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, char-
coal lighter fluid, pellet stove lighter gel or similar liquids to
start or freshen up a fire in this fireplace. Keep all such liq-
uids 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 fireplace.
9. DO not use a fireplace insert or other products not spec-
ified 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 rel-
atively 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 chimney
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 con-
trol 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 manually 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 control open, you can start
experimenting with lower settings. Remember: when the
fireplace is hot, the control will not need as much move-
ment 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 completely
open, you have to run it with the firescreen (FD-FSD) 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.
Page 3

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 FD-
HC4).
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 FD-HB5-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 grav-
ity 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 FD-VD, 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 temperature you desire.
When the blower is running, it takes air from the room the
Delta is in, draws it around the fireplace and distributes it
(see Options: Central Heating System parts FD-HC6/FD-
HB6).
NOTE: The blower (part FD-HB6) 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 cho-
sen 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 exchang-
er. 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 fire-
place, 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 liquids. Once a coal bed is
established, add standard cord wood. Leave the draft con-
trol 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-fit-
ting 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 bur-
ial, or otherwise locally dispersed, they should be retained
in the closed container until all cinders 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 nor-
mal conditions only the door closer should need adjust-
ment. 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 cen-
tre 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 manufactured 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, tighten 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 theAllen
screws in the angle bracket inward. Tighten the two screws
closer to the gasket first then the other two screws. Once
the left part of the door seals well the door closer may need
to be readjusted. If there is no more adjustment in the
door closer the right side door must be loosened and
adjusted slightly 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 FD-GRK7) is available
from your dealer.
The door seal is the most important factor in control-
ling 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 with-
stand 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 replace-
ment 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 clean-
ing. Use only mild soap and warm water to clean the gold
when the surface is cool. The use of any household 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. A
buildup of 1/4 inch or more should be cleaned mechanical-
ly before more creosote accumulates. Use a plastic bristle
or wire brush that fits correctly into the chimney. The baf-
fle 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 fireplace
is still warm. Keep the spray can away from any source of
heat or open flame. Ensure that there is adequate ventila-
tion 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 reason,
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 refractories
R4602 and R4601 should then be positioned taking 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 refractories 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.

INSTALLATION
Check local codes concerning restrictions and installation
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, orbreaking 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 diagram
below. The Delta weighs 620 lbs. complete and 450 lbs.
stripped. The Delta should be stripped before moving 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).
NOTE: When using the optional 45° nailing strip be sure to
line up the 45° nailing strip with the 45° angle on the top
framing guide to ensure facing will be flush.
LOCATION
Your Delta fireplace may be installed in many different
ways (see Figure 5) without any special floor reinforce-
ment.

These framing dimensions are larger than required for
ease of installation. The fireplace has a minimum clear-
ance of 0" to standoffs. (See unit dimensions Figure 18)
Use the provide framing guide to frame
the front of the fireplace
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!
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 com-
bustion air inlet duct to the outside. A4inch diameter 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 diameter 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 circumstances should the combustion 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 insulation 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 insu-
lation 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 cer-
tain 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
outside air connection 2"

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. elevation above
sea level. Every 30° or 45° elbow also increases the min-
imum 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 ineach 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 instruc-
tion 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 roof-
ing 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.
CHASE ENCLOSURE
If the chimney runs up the outside of the house, it must be
enclosed in a chase structure. It is best to locate the chase
away from any overhead obstructions and meet all clear-
ances from such objects. The chase should be construct-
ed 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.
FIRE STOP
A fire stop must be placed where the chimney passes
through each floor level overhead. This will assist in retard-
ing 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

An elbow may be installed directly on top of the fire-
place if required.
Use the offset option if you need to clear a joist or pass
around a cupboard.
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 vertical
direction.
4. Install a roof support, an offset support, or a wall support
after the return elbow, to support the weight of the flue
(elbows are not designed to support a flue above an off-
set). Refer to the Excel chimney installation manual for
more information.
FRAMING IN
The enclosure walls can be framed with any suitable mate-
rials (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 main-
tain top standoff clearances and the 2" clearances 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 (provided).
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 1/2 inches. (Z-SHAPED GUARD NOT SUPPLIED).

MANTEL
Amasonry or other non-combustible mantle may be placed
directly above the top louvers. If a wood or other com-

inches above the top louver opening (see Figures 16 and
17). No combustible material is to be put under mantle.
HEARTH EXTENSION
The area immediately in front of the fireplace must be pro-
tected by a non-combustible 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 thickness 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 FD-HC4). 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 man-
ual adjustment, and reduce wood consumption.
For more heat output and increased air circulation, you can
add the internal blower (part FD-HB5-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 mounting the blower
control.
If you have room directly above or adjacent
to the room with the fireplace which you
would like to heat, you may consider the
gravity vent option (part FD-VD). The gra-
vity vent distributes hot air to this room and
requires no blower to assist its operation.
However, with the internal blower (part FD-
HB5-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 incorpo-
rate the central heat option (parts FD-HC6
and FD-HB6). Athermostatically controlled
blower takes heat from the fireplace, and
distributes the warm air throughout your
home - even several stories up or down.
WALL THERMOSTAT (FD-HC4)
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 fireplace (see
Figure 19).
3. BEFORE fastening the controls with the 2 screws pro-
vided, 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 pendant 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, but in the same
room. An interior wall is recommended for thermostat
installation.
CIRCULATING BLOWER (FD-HB5-N)
NOTE: It is important that the wiring for the blower kit is
installed during framing so that the wiring can be easily hid-
den.
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 con-
ventional 90° C 18 gauge wire (see Figure 20).

GOLD LOUVERS (FD-LD)
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 protruding
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 finger-
prints and dirt off the gold plating. The gold louvers have
been coated with a silicone substance that will seal to the
gold louvers during the first fire. If you do not wipe off the
gold plating, the acid from your fingerprints or other sub-
stances 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 (FD-KD)
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.
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 FD-KD-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 finished.
Acid from the cleaning operation will permanently 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 cosmetic recommendation only.
Installation
1. Start by installing the top centre expanded metal flush
and centred with the top centre louver opening. (It is rec-
ommended 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).
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 facing
material on with wire mesh, or metal lath, overlapping 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, inherently
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 facing. Do not

use only the pre-drilled holes in the rock
retainer kit for screwing to the face
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 following crite-
ria:
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
The gravity vent system can distribute air to an upper level
or a room next door without an extra blower. The central
heat option allows heat to be sent up to 50 ft. away. (Figure
26) illustrates various certified venting options.
THE GRAVITY VENT SYSTEM (FD-VD)
The FD-VD 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 double wall black
pipe ULTRABlack UBF (use only UBF black pipe).
The FD-VD 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 FD-VD . The maximum pipe length is 15 ft.
from the top of the fireplace to the outlet. Remember: dou-
ble 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.

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 fireplace
and the outlet is 15 feet. There is no maximum number
of elbows in a run, but the run must never go in a down-
ward 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 loca-
tion, 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 keyhole, 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. Adefinite tension should exist
between the shut off damper rod and the starter section.
Replace the louvers. 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 1/2" of play.
