SAFETY FIRST
DO'S AND DON'TS
If this fireplace is not properly installed, a house fire may
result. For your safety, follow the installation directions.
Contact local building or fire officials about restrictions
and installation requirements in your area.
NOTE: We strongly recommend installers be WETT or
WHERF certified.
To ANYONE using this fireplace:
These DO’s and DO NOT’s are for your safety.
1. DO read this instruction manual before lighting your
first fire.
2. DO read the section MOVING THE DELTA before
installing (page 10)
3. DO burn seasoned wood fuel only or processed solid
fuel firelogs.
4. To avoid glass breakage, DO NOT slam the fireplace
door.
5. DO NOT use gasoline, lantern-type fuel, kerosene,
charcoal lighter fluid, pellet stove lighter gel or similar
liquids to start or freshen up a fire in this fireplace.
Keep all such liquids well away from the fireplace
while it is in use.
6. DO NOT overfire the fireplace. If the chimney con-
nector behind the top louver glows red, or if you
are unable to slow down the burning rate of the
fire, you are probably overfiring the fireplace.
7. DO operate the fireplace with door fully open or
fully closed. If door is left partly open, gas and
flame may be drawn out of the firplace opening
creating risk of both fire and smoke.
8. DO keep all combustible materials (furniture, shoes
etc.) at least 4 feet away from the front of the fire-
place.
9. DO not use a fireplace insert or other products not
specified for use with this fireplace.
10.DO not operate without or with a damaged gasket. To
do so will cause damage to the fireplace.
CREOSOTE
When wood is burned slowly, it produces tar and other
organic vapours, which combine with expelled moisture
to form creosote. The creosote vapours condense in the
relatively cool chimney flue of a slow burning fire. As a
result, creosote residue accumulates in the flue lining.
When ignited, this creosote makes an extremely hot fire.
The chimney must be inspected periodically during the
heating season to see if a creosote buildup has occurred.
If a significant layer of creosote has accumulated (1/4" or
more), it should be removed to reduce the risk of chim-
ney fire.
Warning: burn seasoned wood only!
Do not burn: - driftwood
- treated wood
- coal
- garbage
- plastic
Do not use construction scraps (e.g., 2x4 or plywood
scraps) as your only supply of fuel, as you may over-
heat and seriously damage the fireplace. Use no
more than 3 densified fuel logs (e.g. Presto Logs), at a
time. Do not poke or stir the logs while they are burning.
Use only firelogs that have been evaluated for fireplace
use and refer to firelog warning and caution markings
prior use.
GENERAL SPECIFICATIONS
COMBUSTION CONTROL SYSTEM
Since the doors are sealed, all combustion air must
come from outside the house through a draft control.
This control has a bimetal coil to allow more air when the
unit is cold, and less air when the unit is hot, guarding
against overheating. It can be controlled either manual-
ly with the lever that is located above the lower right side
louvers, or automatically with an optional electric wall
thermostat.
For the first few days, it is best to operate the fireplace
with the manual control fully open (moved to the right as
far as possible). Just control the fire as you would any
normal fireplace using two or three logs at a time for a
smaller fire, or more logs for more heat. Once you
become familiar with operating the fireplace with the con-
trol open, you can start experimenting with lower set-
tings. Remember: when the fireplace is hot, the control
will not need as much movement to reduce the fire as
when it is cold. The bimetal coil will already have shut
the damper part way.
FIRESCREEN (option)
If you want to use the fireplace with the doors complete-
ly open, you have to run it with the firescreen (FDFSD) in
front of the opening. The firescreen will avoid sparks to
fall on the floor. When using the firescreen do not leave
the fireplace without any supervision. This option is
absolutely needed if you want to use the fireplace the
door open.

DELTA

THERMOSTAT (option)
If you want constant heat, day and night, you will be sur-
prised of what the wall thermostat option can do for you.
Once you have your fire burning, just set the manual con-
trol on low (push the draft control lever all the way to the
left) and let the automatic thermostat take over. Your
room temperature will keep as even as though you were
heating with oil, gas, or electricity - except you will find
wood heat more comfortable (see Options: Wall
Thermostat part FDHC4).
NOTE: This thermostat controls the combustion air rate,
not the internal circulating blower.
INTERNAL CIRCULATING BLOWER (option)
If you have the optional internal blower installed, adjust
the speed of the blower to the output you require. The
blower speed control should have been installed at a
convenient place on the wall. When a fire is burning, the
thermo disc installed inside the fireplace will turn on at
110° F, allowing the blower to operate; this will take about
20 minutes from the time you start the fire. When the
Delta cools to 90°F, the switch deactivates the blower.
The maximum heat output of the fireplace is greater with
the blower running (see Options: Circulating Blower part
FDHB5-N).
GRAVITY VENT SYSTEM (option)
If there are areas in your home that you would like to
heat either in an upper level or an adjacent room, the
gravity vent system can provide this heat with or without
the use of a blower. It is controlled by a gravity vent
damper. The handle is located above the top left louvers
of the fireplace. Simply turn the lever to adjust the air
flow through the gravity vent ducting. As the hot air rises,
it will be distributed through the insulated ducting to the
outlet (see Options: The Gravity Vent System part FDVD,
page 24).
CENTRAL HEAT SYSTEM (option)
You have the option to heat remote rooms in your home
from the heat generated by your fireplace. If this option
is installed, there may be a thermostat installed in the
main room you want to heat, away from the room that
contains the fireplace. Or a thermostat installed that
removes heat from the fireplace when the main room you
are trying to heat reaches the desired temperature. This
thermostat controls the blower, which brings air to the
other rooms in your home, keeping them at the tempera-
ture you desire. When the blower is running, it takes air
from the room the Delta is in, draws it around the fire-
place and distributes it (see Options: Central Heating
System parts FDHC6/FDHB6).
NOTE: The blower (part FDHB6) can push warm air
either up or down, and can also be zone controlled (see
Options: Zone Heating and diagrams).
HINT: If some evening you would like to enjoy the ambi-
ence of the wood flame, but you are a little too warm, turn
up the central heating thermostat and open a window in
the room the ducting goes to. This will keep your room
in front of the fire from getting too warm.
OPERATION
THE FIRST FIRE
Before the first fire, be absolutely sure to wipe off all fin-
gerprints and debris from the gold plating, if you have
chosen this option. The plating undergoes a sealing
process during this first fire, and the acid from your finger
prints will permanently etch the gold plating. You will
experience a slow start-up during the first fire. The
refractory bricks still contain moisture and take a good
hot fire to get rid of the moisture. While there is moisture
in the bricks, the bricks will be black with smoke deposits.
When the moisture is gone, the bricks will turn white.
You will experience an odour during the first few fires.
This odour results from the curing paint and the burn-off
of oil from the heat exchanger. Ventilate room to expel
odours.
LIGHTING
Slide the draft control that is located above the lower
right side louvers all the way to the right. Light a fire in
the fireplace, starting with paper and kindling only. Then
add 2-3" diameter wood. After the fire is established,
close the doors to prevent overheating of the fireplace
face. The unit is designed to accept combustion air
through the outside air duct only. (See the Combustion
Control System, page 5) Never use any flammable liq-
uids. Once a coal bed is established, add standard cord
wood. Leave the draft control open until the fire is well
lit, then adjust it to the level you desire.
Warning: Do not use a grate or elevate the fire.
REFUELLING
Fuel wood can be of any species. However, ensure that
the wood is well seasoned and kept under cover.
NOTE: The central heat and internal blowers, if installed,
should be shut off during refuelling to prevent smoke
from spilling out of the fireplace.
The door should be opened slowly to keep smoke from
spilling into your room. If you do have smoke spillage,
check to see that all kitchen and bathroom fans have
been shut off. They can cause a vacuum in the house,
which pulls smoke out of the fireplace.

MAINTENANCE
CLEANING
The high heat paint and gold plating can be cleaned with
a soft moist cloth. Use a mild detergent and water. Do
not use abrasive cleaners!
ASHES
Clean the ashes before they become too deep, i.e.,
before you have a spillage problem when opening the
doors.
Ashes should be placed in a metal container with a tight-
fitting lid. The closed container of ashes should be
placed on a non-combustible floor or on the ground well
away from all combustible materials. If the ashes are
disposed of by burial, or otherwise locally dispersed, they
should be retained in the closed container until all cin-
ders have thoroughly cooled.
DOORS
Lubricate the door latch and hinges with an all-purpose
grease at least once during the burn season. The door
has been fitted and adjusted correctly at our factory.
Under normal conditions only the door closer should
need adjustment. To adjust the door closer catch, loosen
the two screws that hold the door closer in place. Slide
the door closer in 1/32" increments to the right, tighten
screws and (as shown in figure 1a) test to ensure that the
door closes tightly. To check if the door seal is tight, try to
slide a piece of paper behind the door gasket from the
top and bottom of the door. If the door closes tight and
you can still pass a piece of paper past, the gasket may
need replacing or the doors need readjusting.
If the door has been replaced the following may need
adjusting. First check that the right side door is in the
centre of its adjustment. Adjust the hinges so the door
closer closes the door. The hinges are adjustable by
removing the door, and loosening the small Allen screws
on the right side of the hinge. The hinge pins are manu-
factured off-centre to facilitate easy adjustment. With a
flat screwdriver, the pins can be turned so that the doors
seal well and fit with each other. After adjustment, tight-
en the Allen screws, holding the hinge pins in place with
the screwdriver, and replace the door. If the left side door
fits correctly and the front door does not pass the paper
test, then the angle bracket needs to be adjusted.
Loosen the four screws that are attached to the centre
door and slightly adjust the Allen screws in the angle
bracket inward. Tighten the two screws closer to the gas-
ket first then the other two screws. Once the left part of
the door seals well the door closer may need to be read-
justed. If there is no more adjustment in the door closer
the right side door must be loosened and adjusted slight-
ly to the right. Adjust the left door until the doors seal. If
the door seal is damaged to the point where it does not
seal tightly, the gasket may need to be replaced. The
gasket replacement kit (part FDGRK7) is available from
your dealer.
The door seal is the most important factor in con-
trolling the burn rate of your Delta fireplace.
GLASS
In a controlled combustion firebox, temperatures are not
always high enough to keep the glass perfectly clean.
We have supplied you with special ceramic glass that will
withstand the heat from the fireplace without cracking.
A good hot fire usually cleans off most of the deposits
that have accumulated.
Remember: the drier the wood, the cleaner the glass.
A word of caution: although heat will not break the glass,
be careful not to hit the glass with logs.
NOTE: Cleaner glass means a cleaner flue.
Warning: Never clean this glass with an abrasive
cleaner. Use only a cleaner recommended by your
dealer. Never clean the glass while it is hot.You risk
getting a serious burn.

If your glass breaks
If your glass breaks, call your dealer for the exact
replacement glass and instructions on how to replace the
glass and gasket.
1. Remove the door from the fireplace by lifting it off the
hinges. If the right side glass needs to be replaced
remove door by removing the adjustment/mounting
screws (See Figure 1).
2. Remove the clips holding the glass in place.
3. Clean out any bits of glass and dirt from the gasket.
4. Place the new glass into the opening and replace the
clips, being careful not to overtighten the screws.
5. Check the glass by trying to move it back and forth. It
should feel snug, but move slightly without too much
effort. If the right glass was replaced, replace the door
and adjust it square with the centre door. See section
DOORS if the door needs adjustment.
GOLD PLATING
If you have gold doors or gold louvers, you will be happy
to know that they will not tarnish. However, they are not
scratch resistant and require a totally abrasive free
cleaning. Use only mild soap and warm water to clean
the gold when the surface is cool. The use of any house-
hold clea-ner, such as Windex, abrasive cleaners, or any
form of acid, may permanently etch or remove some of
the gold plating. Before every fire, be absolutely sure to
wipe off all fingerprints from the gold plating. Acid from
debris or your fingerprints may permanently etch the gold
plating.
CHIMNEY CLEANING
Check the chimney for creosote buildup every month
until experience shows how often cleaning is necessary.
Abuildup of 1/4 inch or more should be cleaned mechan-
ically before more creosote accumulates. Use a plastic
bristle or wire brush that fits correctly into the chimney.
The baffle in the firebox can be removed to gain access
to the flue from below.
To remove the baffle, first remove the secondary air pipe.
This can be done by removing the cotter pin from the top
right side of the secondary air pipe and sliding the pipe
as far as it goes to the left. Then when the right side
drops out of its hole, slide it to the right until the other
side drops. To remove the baffle, push up and slide it off
the brackets. Replace both as you removed them and be
sure the holes on the secondary air pipe are facing
toward the front.
PAINT
You may touch up the face of the Delta with STOVE
BRIGHT flat black high temperature paint. The correct
paint is available from your dealer. When you paint the
face of the fireplace, remove or cover the gold items (i.e.,
doors and louvers), and cover the area surrounding the
fireplace with newspaper. Follow the directions outlined
on the spray can. DO NOTattempt to paint while the fire-
place is still warm. Keep the spray can away from any
source of heat or open flame. Ensure that there is ade-
quate ventilation in the room from the time you start
painting until the paint is dry.
REFRACTORY BRICKS INSTALLATION
The refractories or refractory bricks for the Delta fireplace
are placed in the fireplace at the factory. If, for any rea-
son, they should need to be replaced the following order
should be observed.
The bottom refractory R4606 and R4605 should be
placed at the bottom of the firebox. The two rear refrac-
tories R4602 and R4601 should then be positioned tak-
ing care to place them as in the diagram. The two side
refractories R4604 and R4603 are then positioned once
again being careful to place them properly. If the refrac-
tories on the back and sides do not fit immediately into
position as in the diagram they should not be forced. The
refractories can only be fitted into place as they were
designed to do. The last three refractories should be
placed in front from left to right looking at the fireplace
R4608, R4609, and R4607.
These directions should be reversed in order to remove
the refractory bricks from the Delta.

LOCATION
Your Delta fireplace may be installed in many different
ways (see Figure 5) without any special floor reinforce-
ment.
Warning: If this fireplace is not properly installed, a
house fire may result. For your safety, follow the
installation directions and clearances.
1. Note the location of roof and floor joists. Choose a
location that does not require cutting them.
2. If at all possible, run the chimney up the inside of the
house. If it must be run up outside, it should be
enclosed in an insulated enclosure (see Chase
Enclosure). Remember, a cold chimney causes poor
draft!
INSTALLATION
Check local codes concerning restrictions and installa-
tion requirements in your area.
Warning: Remove the left and centre doors and
cover right side door before installation and place
them in a safe area to reduce the possibility of :
a) vandalism;
b) sub-trade tool abrasion, chipping, or breaking of
glass;
c) gold finish damage because of muriatic acid, plaster,
cement, paint and harmful sprays or liquids, and sub-
trade tool abrasion.
MOVING THE DELTA
Due to the weight of the Delta we recommend you use a
furniture dolly and place the Delta as shown in the dia-
gram below. The Delta weighs 620 lbs. complete and 450
lbs. stripped. The Delta should be stripped before mov-
ing it if possible. Elevate the fireplace and dolly to a 45°
angle to move.
NOTE: If using an Eskelera a 2 x 4 will have to be placed
between the two forks before using.
STANDOFF INSTALLATION
Before installing your Delta, the side nailing strips need
to be assembled as follows:
1. Remove the nailing strips from the top of the unit.
2. Remove the four (4) metal screws on each side of the
Delta facing.
3. Attach the nailing strip to the side of the Delta using
the metal screws that you removed in Step 2 (Figure
4).

CEILING CLEARANCE
Ceiling clearance is the distance from the top of the fire-
place to the ceiling.
Under no circumstances is the distance between the ceil-
ing firestop and the top of the framing guide to be less
than 38 inches.
OUTSIDE AIR DUCT
After the fireplace is correctly positioned, connect the
combustion air inlet duct to the outside. A 4 inch diame-
ter can be use if the total run of the pipe is less than 25
feet. If the total run is longer than 25 feet, a 5 inch diam-
eter flexible pipe must be used.
1. Use the side or back outside air outlet.
2. Find a convenient location for
the combustion air duct and
intake air hood. The location
of the intake air hood may be
above or below floor level
(see Figure 7). Under no cir-
cumstances should the com-
bustion air inlet be placed in
attic spaces.
3. Make a 4 1/4" (5 1/4" if using
a 5" diameter duct) hole in the
outside wall of the house.
Mount the register in the hole
from the outside with the inlet
facing down.
4. Place the flexible duct over
the intake air hood tube.
Carefully pull back the insula-
tion and plastic cover, expos-
ing the flexible duct. Then at
each end, attach the duct with
metal screws to the inlet and
tube. Carefully push the insulation and cover back
over the duct. Tape the plastic cover to the end of
flexible duct in place with a 2" aluminium duct tape.
CAUTION: When running duct around corners, make
certain no crimping that would restrict the combustion air
flow occurs.
You must use an insulated duct rated at over 200°F. Our
testing has shown that as long as the 5" diameter insula-
ted duct is utilised properly, there is no restriction on the
length of the run. It is recommended that the duct does
not exceed 12 ft. vertical height rise above the base of
the unit. The air inlet should never be less than 5 ft.
below the top of the chimney flue and shall not terminate
in attic spaces.
CHIMNEY
This fireplace is certified for use with 8" ICC model Excel
chimney. The chimney system height from the top of the
fireplace must be a minimum of 12 ft. and a maximum of
28 ft. The minimum system height of 12 ft. must be
increased by approximately 1 ft. for every 2000 ft. eleva-
tion above sea level. Every 30° or 45° elbow also
increases the minimum height by 1 ft. For example, if
you are living 6000 ft. above sea level, your chimney
must terminate at least 15 ft. from the top of the fireplace
(12 ft. + 3 ft. for the 6000 ft.). See table #1 bellow for
more precise recommended flue heights.
CHIMNEY INSTALLATION
NOTE: The clearance between the chimney and com-
bustible material must be 2" or more. DO NOT fill this
area with insulation.

1. Cut and frame the required holes in the floor, ceiling
and roof where the chimney will pass through. Use a
plumb bob. The framing size is 14 1/4” square.
2. From below, install a radiation shield in each floor
through which the chimney passes. At the attic level,
install a storm collar above the radiation shield as
shown in (Figure 8).
3. Place the first chimney length on the fireplace.
Secure the chimney length to the fireplace with the
three screws provided.
The chimney must extend at least 3 ft. above its point
of contact with the roof and at least 2 ft. higher than
any wall, roof, or building within 10 ft. of it. Refer to the
Excel instruction installation flue height requirements
for penetration above a chase.
If the chimney is higher than 5 ft. above the roof, it
must be secured using a roof brace.
4. Put the roof flashing into place. Seal the joint between
the roof and the flashing with roofing tar. For sloping
roofs, place the flashing under the upper shingles and
on top of the lower shingles. Nail the flashing to the
roof using roofing nails.
If the chimney is enclosed to the roof:
USA: use a vented flashing
Canada: use a roof radiation shield (ERRS)
and a regular flashing
5. Place the storm collar over the chimney and flashing.
Seal it around the chimney with silicone sealer (DO
NOT use roofing tar).
6. Fit the rain cap on the chimney. Secure it tightly in
place.
7. Wash the roof flashing with solvent (or vinegar if the
flashing is galvanized), then paint it with exterior
paint.
Read the Excel Chimney installation manual concerning
requirements for supports bracing anchors, etc.

be enclosed in a chase structure. It is best to locate the
chase away from any overhead obstructions and meet all
clearances from such objects. The chase should be con-
structed in such a way that it is an extension of the home.
It should be well insulated between the footings and the
floor of the home to prevent heat loss. If the climate in
your area is mild, insulate the chase at least to the first
firestop. If the climate in your area is very cold, insulate
the chase to the top to keep the flue warmer, to increase
the draft, and reduce creosote buildup.
If required by local codes, make certain that the walls
have been properly insulated, vapour sealed and
sheathed with a fire rated gypsum board (see Figure 9-
10).
Remember: Check local codes concerning installation
requirements and restrictions in your area.

A fire stop must be placed where the chimney passes
through each floor level overhead. This will assist in
retarding any spread of fire and act to contain the fire
within the area below the firestop.
OFFSET CHIMNEY
• Maximum offset angle: 45°
• Maximum number of elbows: four (4), resulting in two
(2) offsets.
An elbow may be installed directly on top of the fire-
place if required.

Install the fireplace and chimney as described earlier.
When you require an elbow, proceed as follows:
1. Install the required elbow. Turn it in the desired direc-
tion, and fasten it to the other section with 3 metal
screws at the joints.
2. Install enough lengths to obtain the desired offset.
Secure each joint with 3 metal screws.
3. Use another elbow to return the chimney to the verti-
cal direction.
4. Install a roof support, an offset support, or a wall sup-
port after the return elbow, to support the weight of
the flue (elbows are not designed to support a flue
above an offset). Refer to the Excel chimney instal-
lation manual for more information.

FRAMING IN
The enclosure walls can be framed with any suitable
materials (2x4 or 2x6 studs, plywood, gypsum board,
etc.). Because of the high heat output potential of the
Delta, combustible material must NOT go closer to the
fireplace than the stand-offs, top, back and sides. You
may also completely cover the top of the Delta as long as
you maintain top standoff clearances and the 2" clear-
ances around the chased chimney. The 2"
clearance around the chimney must be
open to the fireplace up to the first fire stop
(39½" min.).
SPARK GUARD
Install a 5" piece of sheet metal centred
under the joint between the fireplace and
the hearth extension (see Figure 15). This
is required under the centre door only (pro-
vided). This will make certain that sparks
cannot lodge in the crack and start a fire. If
you are preparing a raised fireplace, then a
“Z” shaped spark guard must be installed.
The height of the Z-shaped hearth guard
must equal the distance between the floor
and the base of the unit. The minimum
depth the spark guard must extend beneath
the Delta is 2 ½ inches. (Z-SHAPED GUARD
NOT SUPPLIED).
MANTEL
A masonry or other non-
combustible mantle may be
placed directly above the top
louvers. If a wood or other
combustible mantle is
desired, then it must be at
least 10 1/2 inches above
the top louver opening (see
Figures 16 and 17). No com-
bustible material is to be put
under mantle.
HEARTH EXTENSION
The area immediately in
front of the fireplace must be
protected by a non-com-
bustible material such as
brick, tile, stone, or slate.
The protection must extend
at least 16" in front and 8" on
both sides of the fireplace
opening (see Figure 16).
There is no minimum thick-
ness required for the hearth
extension.

DELTA OPTIONS
Just a few comments about your Delta options. The size
and shape of your home and how you intend to use your
fireplace will determine the options you require.
For a basic, high-efficiency fireplace, you won’t need any
options or electricity.
Temperature control can be accomplished by adding the
thermostat option (part FDHC4). The thermostat automa-
tically controls the amount of combustion air to the fire,
leaving your home at an even preset temperature. If you
plan to heat your home with the fireplace, the thermostat
option will increase comfort, end the fuss of continual
manual adjustment, and reduce wood consumption.
For more heat output and increased air circulation, you
can add the internal blower (part FDHB5-N). For larger
homes in colder climates, this is an important option if
you plan to use the fireplace as an important source of
heat.
NOTE: It will be difficult to install the internal blower if
wiring is not run during framing. If there is any chance
that this option will be installed in the future, power
should be run to the fireplace and wire must be run to a
switch box at a convenient place on the wall for mount-
ing the blower control.
If you have room directly above or adja-
cent to the room with the fireplace which
you would like to heat, you may consider
the gravity vent option (part FDVD). The
gra-vity vent distributes hot air to this
room and requires no blower to assist its
operation. However, with the internal
blower (part FDHB5-N) installed, there will
be some increase in warm air movement
to the room serviced by the gravity vent.
If you desire even heat throughout your
home strictly from your fireplace, or if you
want to move heat to a remote area of your
home, it is recommended that you incor-
porate the central heat option (parts
FDHC6 and FDHB6). A thermostatically
controlled blower takes heat from the fire-
place, and distributes the warm air
throughout your home - even several sto-
ries up or down.
WALL THERMOSTAT (FDHC4)
This optional kit allows you to control the
temperature by a remote electric wall
mounted thermostat.
NOTE: It is strongly recommended that
this kit be installed during framing so that
the wiring can be easily hidden.
1. Remove both right side louvers. They are held in
place by springs underneath, so push down from the
top and pull forward.
2. The damper motor and transformer are mounted on a
bracket in the bottom right hand corner of the fire-
place (see Figure 19).
3. BEFORE fastening the controls with the 2 screws
provided, thread the supplied chain through the spare
keyhole in the draft control and attach a pendant to
the end, just like the chain that is beside it. Let the
chain down on the same side of the heat shield as the
existing chain, and attach it to the lever on the
damper motor with another pendant. Push the pen-
dant snug into the hole in the lever. Then mount the
controls to the bracket.
4. Adjust the chain on the draft control lever until it is just
snug but the damper is still closed. When the damper
motor is energized, the damper should open all the
way. Lock the chain onto the keyhole with another
pendant just like the chain beside it.
5. Wire the thermostat as shown in (Figure 19), using
20/2 wire, making sure the wall control is sufficiently
away from the direct radiation of the fireplace. Make
certain that it is at least 10 ft. away from the fireplace,

ed for thermostat installation.
CIRCULATING BLOWER (FDHB5-N)
NOTE: It is important that the wiring for the blower kit is
installed during framing so that the wiring can be easily
hidden.
1. Remove the bottom middle louver. It is held in place
by springs underneath. Therefore, push down from
the top and pull forward.
2. Hold the blower with the outlet facing up from the
back. Fit the blower through the louver opening.
3. Slide the blower into the two blower mounts being
sure that it is pushed all the way down.
4. Mount the thermo disc as shown in (Figure 21). The
front face of the fireplace is bent into a flange just
above the lower opening. The thermo disc mounts
just above the centre louvers. Push the clips on to the
flange as far as they will go.
NOTE: One thermo disc is all that is required to operate
either the internal blower, the central heat blower, or
both.
5. Mount the provided speed control in a switch box at a
convenient location on the wall and connect it with
conventional 90° C 18 gauge wire (see Figure 20).
GOLD LOUVERS (FDLD)
The standard black louvers above and below the doors
can be replaced with a gold plated set. You may order
these from your dealer.
Dismantling and assembling louvers
For the following refer to (Figure 22):
1. The louvers are held in place by springs underneath.
Therefore, to remove, push down from the top and
pull the top of the louvers forward.
2. Take the assembly apart by removing the top nuts
from the rods. Leave the bottom nuts and spring
assemblies on the ready rod.
3. Assemble the louvers the same way the black ones
came apart, reusing the original rods, spacers and
springs. There should be about 1/4" of the rod pro-
truding above the top nut.
4. Put the reassembled louvers back into the
fireplace by inserting the rods into the lower
holes, and pushing the louvers into place.
Warning: Be sure to replace the heat shield
behind the top centre louvers the same way
it was removed. Failure to do this may
result in a fire hazard (see Figure 22).
IMPORTANT! Before you light the first fire
after you have installed the new louvers, you
must wipe all fingerprints and dirt off the gold

plating. The gold louvers have been coated with a sil-
icone substance that will seal to the gold louvers dur-
ing the first fire. If you do not wipe off the gold plating,
the acid from your fingerprints or other substances will
permanently etch the gold plating.
NOTE: Although the gold plating will not tarnish, care
must be taken not to scratch the surface.
DELTA ROCK RETAINER KIT (FDKD)
Facing
Facing material may only be non-combustible such as
metal, brick, rock, concrete board, or ceramic tile.
Gypsum board is NOT an acceptable facing material.
Page 16
DELTA
Warning: DO NOT restrict air flow through the inlet and
outlet louvers of the fireplace.
If you desire to fully face the fireplace with soldiering
brick, it is recommended that you purchase the rock
retainer kit (part FDKD-1) to help keep the facing in
place. It is NOT recommended for brick or other self-
supporting materials. Follow these steps:
NOTE: Remove the fireplace doors and louvers, and
store them in a safe place until the masonry work is fin-
ished. Acid from the cleaning operation will permanent-
ly damage the gold plating. Ensure that the cover
remains over the right door.
NOTE: The louvers have two sets of mounting holes.
Use the rear set when there is no
facing added to the fireplace and
use the front set when a facing
has been added. This is a cos-
metic recommendation only.
Installation
1. Start by installing the top cen-
tre expanded metal flush and
centred with the top centre
louver opening. (It is recom-
mended that you just clamp
the centre piece in place until
the sides are lined up) Next
install the right and left
expanded metal by aligning
the edging and the mesh to
the centre piece and the side
louver openings. Now install
the lower arch centre above
the door aligning it to the side
pieces (see Figure 23).

away. (Figure 26) illustrates various certified venting
options.
THE GRAVITY VENT SYSTEM (FDVD)
The FDVD Kit (see figure 27) includes:
- a grille
- a grille adapter
- a B-vent starter section
- a shut-off damper
IMPORTANT: No substitution of any of these parts is
allowed. These genuine RSF Woodburning
Fireplaces parts have the correct clearances. These
clearances must be maintained for your safety exept
that B-vent components can be replace by ICC dou-
ble wall black pipe ULTRABlack UBF (use only UBF
black pipe).
The FDVD system incorporates standard 8" B-vent com-
ponents for installation. Single wall pipe is not allowed
due to the high temperature of the air in a gravity vent
system. Any listed brand of 8" B-vent pipe may be used
and is not a part of the FDVD . The maximum pipe length
is 15 ft. from the top of the fireplace to the outlet.
Remember: double wall black pipe from ICC may be
used instead of B-vent pipe.
(Figure 28) indicates the minimum clearances
and framing dimensions. Passing through a
combustible wall or ceiling requires a minimum
clearance of 2" from combustibles.
Warning: Every measurement and clearance
on the illustrations must be followed to
assure safety of the installation.
NOTE: When using wider lintel bar for heavier rock,
make sure that you have enough room to open the door
wide.
2. Cover any remaining area which you wish to put fac-
ing material on with wire mesh, or metal lath, over-
lapping the heavy expanded metal. Make sure nails
or staples used for fastening mesh penetrate the
studs at least 1".
3. Mortar must be "thin set" or "thin bed" type, inherent-
ly polymer modified. Do not add water to the mixture
(this applies to the grout as well). If the mortar is not
modified, you should add a synthetic latex additive.
Mix to a firm, moist consistency.
4. Using a plasterer’s or mason’s trowel, apply a scratch
coat that covers the wire mesh. Let the mortar set
before adding another coat. This will take several
hours. Afterwards, apply a thinner coat and the fac-
ing. Do not spread plaster over more than a workable
area so that the mortar will not set before the facing is
applied.
5. If additional mortar is required, use a grout bag to fill
in the joints. Take extra care to avoid smearing on the
surface of the facing.
Optional redesign of upper louver area
You may use other decorative materials to cover the
upper louver area. However, you must follow the follow-
ing criteria:
If any material is placed in front of the louvers (brick, tile,
etc.) the louvers must first be permanently removed.
The final open area over the louver must be at least 50%
of the area of the opening or 100 square inches. For
example see (Figure 25).
REMOTE VENTING

grill

Installation
CAUTION: Do not replace the grille from (Figure 28)
with shutters. Do not allow heat to be trapped in the
gravity vent system.
1. Plan the gravity vent run first. Be aware that the max-
imum actual pipe length between the top of the fire-
place and the outlet is 15 feet. There is no maximum
number of elbows in a run, but the run must never go
in a downward direction as this can trap heat in the
gravity vent system.
2. The grille adapter is designed to be installed under-
neath the gypsum board in the wall. In the desired
location, frame a 13" x 13" hole to accept the gravity
vent grille adapter. Fit the gravity vent grille adapter
into the framed hole and fasten it into place with nails
or screws. If you are installing the outlet in an already
finished area, you must remove the gypsum board
and frame a 13" x 13" hole in the existing framing, in
order to meet the required clearances.
3. Remove the outer cover to the left side of the flue out-
let on the Delta.
4. Cut the insulation to the size of the opening and slide
the cover plate underneath to the side (it is taped in
place).
5. Install the B-vent starter section. By putting your hand
up inside and underneath, bend up at least two of the
four tabs at the base of the starter section to hold it
in place.
6. Install the “shut-off” damper in the B-vent starter sec-
tion through the left side louvers. The shut-off damper
enables the manual control of hot air flowing through
the gravity vent pipe. With the top left louver
removed, and the angular portion of the rod in hand,
insert the damper rod into the rear hole in the starter
section. The rod should slide in and down the key-
hole, making sure that the #2 washer and spring on
the control arm are both on the outside of the starter
section and #1 washer is inside the starter section. A
definite tension should exist between the shut off
damper rod and the starter section. Replace the lou-
vers. The damper rod should protrude above the top
of the louvers.
7. Install the B-vent pipe between the B-vent starter and
the grille adapter. Fasten each joint with 3 screws (if
the B-vent pipe manufacturer allows this in their
instruction manual). Insert the B-vent pipe in the grille
adapter and fasten it with three screws. The B-vent
pipe needs only to be inserted into the adapter
enough to be able to screw it in place. This allows
you about 3 ½" of play.

operation.
THE CENTRAL HEAT SYSTEM
To install the central host option you will need:
1. Part FDHC6:A blower transformer relay, a thermostat
and a thermo disc (Figure 30).
2. Part FDHC6-1: A back draft damper (Figure 30).
3. Part FDHB6: A maximum 636 c.f.m. blower with a
variable speed motor, 2 noise reduction collars, a
blower speed control, and a mounting bracket (Figure
29).
NOTE: Both part numbers must be used together for this
system. Use of any substitutes will decertify the system.
When ducting from the top of the fireplace the 8" back
draft damper prevents hot air from trav-
elling into the ‘C’ vent (single wall) duct-
ing unless the Central Heat Blower
(FDHB6) is operating. When the ther-
mostat calls for heat, the blower turns
on and opens the one-way valve. At the
same time, the room air is drawn
through the upper and lower louvers,
which mixes and reduces the overall
temperature of the forced air that travels
through the ducting.
NOTE: The central heat ducting may be
run at a 0" clearance to combustibles.
Warning: If you are ducting out of the top of
the fireplace and the backdraft damper is not
installed, the central heat ducting will
become too hot for the surrounding com-
bustible materials. Any substitute for any
RSF kit will void all liability and warranty
coverage by RSF Woodburning Fireplaces.
Installation
1. Remove the cover to the left on the top of the
Delta.
2. Cut the insulation to the size of the opening
and slide the cover plate underneath to the
side (it is taped in place).
3. Install the back draft damper crimped side
up, making sure it is pushed all the way
down. Bend out the 4 top tabs once install
bend out the tabs on the lower edge of the
damper in at least 2 places inside the fire-
place with a pair of pliers, so the back draft
damper cannot be pulled out again.
4. Before proceeding with the installation of the
blower,
make sure that the electrical service to the
blower is in the “OFF” position. All wiring
should be in accordance with local ordi-
nances and the National Electric Code.
NOTE: The blower can basically be installed
anywhere in the home. However, some thought
should go into the planning, to ensure that the

blower noise does not affect rooms you would like kept
quiet. If the central heating system duct work is passing
through an area in your home that you do not wish to be
heated, then the ducting should be insulated. Length of runs
should be as short as possible to conserve space and mini-
mize cost. There is a loss of about 15% performance at 50
feet. Also: for your safety the blower automatically shuts
off if the air temperature reaches 180° F inside the ducting.
5. Locate the blower in a convenient location. The blower
may be installed vertically or horizontally. The horizontal
installation can utilize either the supplied mounting brack-
et or, if you want to install the blower farther away from
the ceiling, you can use plumber’s strapping. A vertical
installation must include the mounting bracket.
NOTE: If you have an existing hot air system, you may safe-
ly tie-in to this hot air system. However, no hot air duct is to
be connected to the return air of another central heat-
ing system.
6. Connect the INLET of the blower to the ducting coming
from the fireplace, using 8" diameter metal ducting (rigid
or flex). Any other size will not work properly. Use only
metal ducting between the fireplace and the blower. You
may use plastic ducting after the blower, provided the
temperature rating of the ducting is at least 250°F. Do
not use plastic ducting in a chase.
7. To install the blower (for the FDHB6 blower only), attach
the noise reduction collars to either side of the blower
using 1/2" self-tapping screws.
8. Duct-work can then be run to the desired rooms. Up to
six - 5" or five - 6" diameter runs can be installed from this
system.
NOTE: Runs must be balanced as air travels along the path
of least resistance. Balance the air flow by diameter and
length of runs. Longer runs should have larger diameters.
Houses vary in size and layout, so duct systems must be
specifically designed for each home. The diagrams on
this sheet are examples only. The cross sectional area of the
distribution system must total at least 50 square inches. If
you have more than 50 square inches, some of the system
may be shut off, but there must always be 50 square inches
of ducting open at all times. For example, if 5" pipe is used
for distribution, the cross section of each is 20 square inch-
es. The minimum allowable ducting would be three runs
of 5" pipe.
(Figure 33 and 34) illustrate two examples of tying in to exist-
ing duct work. Directing air in the right direction will reduce
reverse flow when the existing furnace blower is off. Some
reverse flow will not cause any problems.
CAUTION: Tie-ins into existing duct work must be down
stream from the existing furnace.
NOTE: When the central heating blower is in operation, it
removes air from the room containing the fireplace. If this
room can be closed off from the rest of the house (e.g. with
a door), a grille with at least a 100 square inch open area
