FOR SAFE INSTALLATION AND OPERATION PLEASE
NOTE THE FOLLOWING:
1 . This fireplace gives off high temperatures and should
be located out of high traffic areas and away from
furniture and draperies.
2. Children and adults should be alerted to the hazards
of fireplace high surface temperatures and should
stay away to avoid burns or ignition of clothing.
3. CAUTION: Due to high glass surface temperature
children should be carefully supervised when in
the same room as fireplace.
4. Under no circumstances should this fireplace be
modified. Parts removed for servicing should be
replaced prior to operating this fireplace again.
5. Installation and any repairs to fireplace must be
performed by qualified installer, service agency or gas
supplier. A professional service person should be
contacted to inspect fireplace annually. More frequent
cleaning may be required due to excess lint and dust
from carpeting, bedding material, etc.
6. Control compartments, burners and air passages in
this fireplace should be kept clean and free of dust
and lint. Make sure that the gas valve and pilot light
are turned off before you attempt to clean this
fireplace.
7. The venting system (chimney) of this fireplace should
be checked at least once a year and if needed your
venting system should be cleaned.
8. Keep the area around your fireplace clear of combusti-
ble materials, gasoline and other flammable vapour
and liquids. This fireplace should not be used as a
drying rack for clothing, nor should Christmas stockings
or decorations be hung on or around the fireplace.
9. Under no circumstances should any solid fuels (wood,
coal, paper or cardboard etc.) be used in this
fireplace.
10. The flow of combustion and ventilation air must not be
obstructed in any way.
11. When the fireplace is installed directly on carpeting,
vinyl tile or any combustible material other than wood,
this fireplace must be installed on a metal or wood panel
extending the full width and depth of the fireplace.
12. This fireplace requires adequate ventilation and
combustion air to operate properly.
13. This fireplace must not be connected to a chimney flue
serving a separate solid fuel burning fireplace.
14. When the fireplace is not in use it is recommended
that the gas control valve be left in the OFF position.
IMPORTANT:
PLEASE REVIEW THE FOLLOWING CAREFULLY
Remove any plastic from parts before turning the
fireplace ON.
It is normal for fireplaces fabricated of steel to give
off some expansion and/or contraction noises
during the start up or cool down cycle. Similar
noises are found with your furnace heat exchanger
or car engine. It is not unusual for your gas fireplace
to give off some odor the first time it is burned. This
is due to the curing of the paint and any undetected
oil from the manufacturing process.
Please ensure that your room is well ventilated-
open all windows.
It is recommended that you burn your fireplace for
at least ten (10) hours the first time you use it. If the
optional fan kit has been installed, place the fan
switch in the “OFF” position during this time.

PREPARATION
GAS LINE INSTALLATION
The use of wall paper adjacent to this
fireplace is not recommended, as the
high heat given off by this fireplace may
adversely affect the binders in the
adhesive used to apply the wallpaper.
Before beginning, remove the window frame assembly
from the fireplace. Also check to make sure there is not
hidden damage to the fireplace. Take a minute and
plan out the gas, vent and electrical supply. See
Window Frame Assembly Section.
When purging the gas line, the front
glass must be removed.
The gas pipeline can be brought in through the rear of
the fireplace as well as the bottom. Opening is provided
on the bottom behind the valve to allow for the gas pipe
installation and testing of any gas connecion. It is most
convenient to bring the gas line in from the rear right
side of the valve, as this allows fan installation or
removal without disconnecting the gas line.
The gas line connection can be made
with properly tinned 3/8” copper tubing,
3/8” rigid pipe or an approved flex con-
nector. Since some municipalities have
some additional local codes, it is always
best to consult your local authority and
the CSA-B149 (.1 or .2) installation code.
For USA Installations consult the current
National Fuel Gas Code, ANSI Z223.1.
Always check for gas leaks with a mild
soap and water solution. Do not use an
open flame for leak testing.
The gas control is equipped with a
captured screw type pressure test point,
therefore it is not necessary to provide a
1/8” test point up stream of the control.
This appliance may be installed in an aftermarket
permanently located, manufactured (mobile) home,
where not prohibited by local codes.
This appliance is only for use with the type of gas
indicated on the rating plate. This appliance is not
convertible for use with other gases, unless a
certified kit is available and used.
Fig. 2
Input ratings are shown in BTU per hour and
are certified without deration for elevations up
to 4,500 feet (1,370 m) above sea level.
For elevations above 4,500 feet (1,370 m) in
USA, installations must be in accordance with
the current ANSI Z223.1 and/or local codes
having jurisdiction.
In Canada, please consult provincial and/or
local authorities having jurisdiction for install-
ations at elevations above 4,500 feet (1,370 m).

The remote ON/OFF switch can not be fitted to units
using the Honeywell Radio Frequency control valve.
If the fireplace has been fitted with the Radio
Frequency Control Valve, the ON/OFF function is
controlled by the remote handset. (See the Comfort
Control Valve Operating Instruction Section).
Install on/off switch assembly on either the rear right or
left side of the Fireplace.
1. Remove the screw at the back of the cabinet top
either on the left or the right side of the fireplace.
2. Position switch assembly onto the back of the
fireplace, then fasten two screws as shown in Fig. 5.
3. Attach wiring under the clips on the rear casing
(Fig. 5) and install wiring through the rear opening
of the fireplace before connecting to the valve as
shown in Fig. 4.
When using copper or flex connector use only ap-
proved fittings. Always provide a union when using
black iron pipe so that gas line can be easily
disconnected for burner or fan servicing (see Fig. 2)
See gas specification for pressure details and ratings.
The fireplace valve must not be
subjected to any test pressures
exceeding 1/2 psi. Isolate or disconnect
this or any other gas appliance control
from the gas line when pressure testing.

Before joining elbows and pipes apply a bead of high
temperature sealant to the crimped end of the elbow or
pipe. Join the pipes using a 2” (50mm) overlap and
secure the joints with three (3) sheet metal screws
(Fig. 11). Wipe off excess sealant.
There are polished brass decorative
rings available to hide the exposed
piping joints. Wrap the brass ring over
the joint fitting the stud into the notch
and tighten down the 3/8” nut.
GENERAL INFORMATION ON ASSEMBLING
THE VENT PIPES IN DIRECT VENT APPLICATIONS
CANADIAN INSTALLATIONS:
The venting system must be installed in accordance
with the current CSA-B149 (.1 or .2) installation code.
USA INSTALLATIONS:
The venting system must conform with local codes
and/or the current National Fuel Gas code ANSI
Z223.1.
Fig. 11
Screw Holes
Fig. 12
CRIMPED END PIPES TWIST LOCK PIPES
When using twist-lock pipe it is not necessary to use
sealant on the twist lock joints.
The only areas of the venting system that need to be
sealed with high temperature silicone sealant are the
collars on the fireplace and termination, and the sliding
joint of any telescopic vent section used in the system.
To join the twist lock pipes together, simply align the
beads of the male end with the grooves of the female
end, twisting the pipe until the flange on the female
end contacts the external flange on the male end.
It is recommended that you secure the joints with three
(3) sheet metal screws, however this is not mandatory
with twist lock pipe.
To make it easier to assemble the joints we suggest
putting a lubricant (Vaseline or similar) on the male
end of the twist lock pipe.

VERTICAL SIDEWALL APPLICATIONS
Since it is very important that the venting system
maintain its balance between the combustion air intake
and the flue gas exhaust, certain limitations as to vent
configurations apply and must be strictly adhered to.
The graph, on page 11, showing the relationship
between vertical and horizontal side wall venting will
help to determine the various lengths allowable.
Minimum clearance between vent pipes and
combustible materials is one 1” (25mm) on top, bottom
and sides unless otherwise noted.
When the vent termination exits through
foundations less than 20” below siding outcrop,
the vent pipe must flush up with the siding.
It is always best to locate the fireplace in such a
way that minimizes the number of offsets and
horizontal vent length.
The horizontal vent run refers to the total length of
vent pipe from the flue collar of the fireplace to the
face of the outer wall.
Horizontal plane means no vertical rise exists on
this portion of the vent assembly.
VERTICAL SIDEWALL INSTALLATIONS
• The maximum number of 90°elbows per side wall
installations is three (3).
• For IRFSDV24 and IRFSDV34 models the
maximum horizontal run off a minimum 12” vertical
rise is 3’ (see Fig. 15).
• If a 90˚ elbow is used in the horizontal vent run
(level height maintained) the maximum horizontal vent
length is reduced by 36 inches, (Fig. 14). This does not
apply if the 90˚ elbows are used to increase or redirect
a vertical rise (Fig. 16).
Example: According to the chart the maximum
horizontal vent length is 20’ and if a 90˚ elbow
is required in the horizontal vent it must be
reduced to 17’.
In Fig. 14, Dimension A plus B must not be
greater than 17’ (5.2m).
• The maximum number of 45°elbows permitted per
side wall installation is two (2). These elbows can be
installed in either the vertical or horizontal run.
• For each 45°elbow installed in the horizontal run,
the length of the horizontal run MUST be reduced by
18” (45cm). This does not apply if the 45°elbows are
installed on the vertical part of the vent system.
• The maximum number of elbow degrees in a system
is 270°(Fig. 13).
Example: In Figure 13
Elbow 1 = 90°
Elbow 2 = 45°
Elbow 3 = 45°
Elbow 4 = 90°
Total angular variation = 270°

To The Center Of The Horizontal Vent Pipe
TO USE THE VENT GRAPH
SIDEWALL VENTING GRAPH
(Dimensions In Feet)
1. Determine the height of the center of the horizontal
vent pipe exiting through the outer wall. Using this
dimension on the Sidewall Vent Graph below, locate
the point it intersects with the slanted graph line.
2. From the point of this intersection, draw a vertical
line to the bottom of the graph.
3. Select the indicated dimension, and position the
fireplace in accordance with same.
Example A:
If the vertical dimension from the floor of the
fireplace is 11’ (3.4m) the horizontal run to the face
of the outer wall must not exceed 14’ (4.3m).
Example B:
If the vertical dimension from the floor of the unit is
7’ (2.14m), the horizontal run to the face of the
outer wall must not exceed 8-1/2 (215mm).

STEP 1
Locate vent opening on the wall. It may be necessary to
first position the fireplace and measure to obtain hole
location. Depending on whether the wall is combustible or
noncombustible, cut opening to size (Fig. 17).
(For combustible walls first frame in opening. Fig. 17)
COMBUSTIBLE WALLS: Cut a 9-3/8”H x 9-3/8” W (240
mm x 240 mm) hole through the exterior wall and frame
as shown Fig. 14.
NONCOMBUSTIBLE WALLS: Hole opening must be 7.5”
(190 mm) in diameter.
STEP 2
Measure wall thickness and cut zero clearance sleeve
parts to proper length (MAXIMUM 12”/305 mm). Assem-
ble sleeve and attach to firestop with #8 sheet metal
screws (supplied). Install firestop assembly (Fig. 18).
Zero clearance sleeve is only required for
combustible walls.
STEP 3
Place fireplace into position (Fig. 19). Measure the
vertical height (X) required from the base of the flue
collars to the center of the wall opening.
STEP 4
Apply a bead of silicone to the inner and outer flue
collars of the fireplace (Fig. 20) and using appropriate
length of pipe section(s) attach to fireplace with three (3)
screws. Follow with the installation of the inner and outer
elbow, again secure joints as described on page 9.

When it is not possible to meet the required vent
terminal clearances of 12 inches (305mm) above grade
level a snorkel vent kit is recommended. It allows
installation depth of down to 7 “ (178mm) below grade
level. The 7 “ is measured from the center of the
horizontal vent pipe as it penetrates through the wall.
If venting system is installed below
ground, we recommend a window well
with adequate and proper drainage.
Ensure sidewall venting clearances are observed.
Support horizontal pipes every 3’ (91 cm)
with metal pipe straps.
Check fireplace to make sure it is lev-
elled and properly positioned.

STEP 6
Note: If using the charcoal wall plate, Part #52202-CG,
and collar, Part #52203-CG, put them in place before
putting the pipe sections through the wall.
Use appropriate length of pipe sections - telescopic or
fixed - and install. The sections which go through the
wall are packaged with the starter kit, and can be cut to
suit if necessary (Fig. 22).

Sealing vent pipe and firestop gaps with
high temperature sealant will restrict
cold air being drawn in around fireplace.
STEP 7
Apply high temperature sealant to 4” (100 mm) and 7”
(175 mm) collars or the termination one inch away from
crimped end. Guide the vent terminations 4” and 7”
collars into their respective vent pipes. Double check
that the vent pipes overlap the collars by 2” (50mm).
Secure the termination to the wall with screws provided
and caulk around the wall plate to weatherproof.

If the foundation is recessed, use recess brackets (not
supplied) for securing lower portion of the snorkel.
Fasten brackets to wall first, then secure to snorkel
with self drilling #8 x 1/2 sheet metal screws. It will be
necessary to extend vent pipes out as far as protruding
wall face (Fig. 25).
This Gas Fireplace has been approved for,
• Vertical installations up to 40’ (12m) in height. Up
to a 10’ horizontal vent run can be installed within
the vent system using a maximum of two 90°
elbows (Fig. 26).
• Up to two 45°elbows may be used within the
horizontal run. For each 45°elbow used on the
horizontal level the maximum horizontal length
must be reduced by 18”.
Example: Maximum horizontal length
0x 45°elbows = 10’
1x 45°elbows = 8.5’
2x 45°elbows = 7’
• A minimum of an 8’ vertical rise.
• Two sets of 45°elbows offsets within these vertical
If installing a snorkel a minimum 24” vertical rise is
necessary. The maximum horizontal run with the 24”
vertical pipe is 36” (915 mm). This measurement is
taken from the collar of the fireplace to the face of the
exterior wall. See the Vent Chart on page 11 for
extended horizontal run if the vertical rise exceeds 24”.
1. Establish vent hole through the wall (Fig. 17).
2. Remove soil to a depth of approximately 16"
(406mm) below base of snorkel. Install drain pipe.
Install window well (not supplied). Refill hole with
12" (305mm) of coarse gravel leaving a clearance
of approximately 4" (100mm) below snorkel (Fig.
24).
3. Install vent system.
4. Ensure a watertight seal is made around the vent
pipe coming through the wall.
5. Apply high temperature sealant caulking (supplied)
around the 4” and 7 “ snorkel collars.
6. Slide the snorkel into the vent pipes and secure to
the wall.
7. Level the soil to maintain a 4" (100mm) clearance
below snorkel (Fig. 24).

It will be necessary to clean the glass periodically.
During start-up condensation, which is normal, forms
on the inside of the glass. This condensation causes
lint, dust and other airborne particles to cling to the
glass surface. Also initial paint curing may deposit a
slight film on the glass. It is therefore recommended
that the glass be cleaned two or three times with a
non-ammonia based household cleaner and warm
water (We recommend gas fireplace glass cleaner).
After the initial cleaning process the glass should be
cleaned two or three times during each operating
season depending on the environment.
• The use of substitute glass will void all pro-
duct warranties.
• Care must be taken to avoid breakage of the glass.
Under no circumstances should this
fireplace be operated without the front
glass or with a broken glass.
Replacement of the glass (with gasket)
as supplied by the manufacturer should
be done by a licensed qualified
service person.
Clean glass after first two weeks
of operation.
