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.

A hearth is not mandatory but is recommended for
aesthetic purposes. We recommend a noncombustible
hearth which projects out 12” (305 mm) or more from
the front of the fireplace. The hearth cannot exceed 1¹⁄₂”
(38mm) in height from bottom of fireplace for ease of
door accessibility. (Fig. 5)
Cold climate installation recommendation:
When installing this unit against a non-
insulated exterior wall or chase, it is
mandatory the outer walls be insulated to
conform to applicable insulation codes.
If a vapor barrier is used it can not come into
contact with fireplace.
Hearth
Mantels
The height that a combustible mantel is fitted above the
fireplace is dependent on the depth of the mantel. This
also applies to the distance between the mantel leg (if
fitted) and the fireplace.
For the correct mounting height and widths refer to
Figs. 4a and 4b, the following Mantel Charts.
Noncombustible mantels and legs may be installed at
any height and width around the appliance.
When using paint or lacquer to finish the mantel, such
paint or lacquer must be heat resistant to prevent
discoloration.

7. The U-channel located on the top of the unit as well
as the nailing flanges on the sides that were men-
tioned in Step 1, are designed to accommodate non-
combustible board (recommended Dura-Rock). They
are positioned 1” (25mm) back from the face of the
unit. NOTE: The U-channel depth can be adjusted
by loosening the hex nut inside the channel.
If marble, tile or any other noncombustible decora-
tive face finish material is desired, a 3” (76 mm) wide
noncombustible board (recommended Dura-Rock)
is to be nailed to the nailing flanges on both sides
of the unit. Also, 12” (305 mm) of noncombustible
board is to be nailed to the front face of the U-chan-
nel and the top framing member above the standoff.
Combustible material can then be brought to the
outside edges of the noncombustible board installed
earlier. Any noncombustible decorative face finish
could be brought to the sides and top of the unit and
can cover the framing and sheet rock. If a decora-
tive facing is not desired, then the noncombustible
boards must be double thickness and brought flush
with the face of the unit.

The fireplace, when installed, must be elec-
trically connected and grounded in accord-
ance with local codes or, in the absence
of local codes, with the current CSA C22.1
Canadian Electrical Code or the national
electrical code ANSI/NFPA No. 70 in the
USA.
It is strongly suggested that the wiring of
the Electrical Junction Box be carried out
by a licensed electrician. The box should
be near the valve box assembly to plug the
cord into.
Ensure the power to the supply line has
been disconnected before commencing
this procedure.
Electrical Junction Box (E Units Only)
Do not wire the remote ON/OFF wall switch
for this gas appliance into a 120V power
supply.
The unit is equipped with an ON/OFF rocker switch at
the valve box assembly. If a wall switch is desired, fol-
low these instructions.
1. The valve box is equipped with two knockouts at
the top right and left corners. The right knockout is
designed to run the wall switch wires to the valve.
Use Romex connectors when running wires through
the valve box where the knockouts are located.
2. Attach the wire to the ON/OFF switch and install the
switch into the receptacle box.
3. Connect the other end of the wire to the gas control
valve. (Fig. 10)
Remote ON/OFF Switch This appliance may be fitted with a Honeywell ignition
module. The unit is shipped from the manufacturer with
an ON/OFF switch. The ON/OFF switch is located in
the valve box assembly. If desired a wall switch may be
used.
Installation of the remote ON/OFF switch on electronic
ignition units:
1. The valve box is equipped with two knockouts at the
top right and left corners. The right knockout is de-
signed to run the wall switch wires to the valve. The
left knockout is designed for wiring the electronic
unit (E model) to 120v with proper grounding. Use
Romex connectors when running wires through the
valve box where the knockouts are located.
2. Attach the wire to the ON/OFF switch and install the
switch into the receptacle box. (Fig. 11)
3. Connect the White wire from the wall switch to the
Black wire from the transformer, using an approved
wire nut or terminal. Connect the Black wire from the
wall switch to the Black wire running from the #6 po-
sition of the ignition module, also using an approved
wire nut or terminal.
Electronic Gas Control Valve
Always check for gas leaks with a mild
soap and water solution applied with a
brush no larger than 1” (25mm). Never ap-
ply soap and water solution with a spray
bottle. Do not use an open flame for leak
testing.
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.
The gas control is equipped with a captured screw type
pressure test point, therefore it is not necessary to pro-
vide a 1/8” test point up stream of the control.
When using copper, use only approved fittings. Always
provide a union when using black iron pipe so the gas
line can be easily disconnected for burner servicing. A
union may not be behind a wall. (Fig. 9) See the gas
specifications for pressure details and ratings.

Your fireplace is approved to be vented either through
the side wall, or vertical through the roof.
• Only CFM Corporation venting components spe-
cifically approved and labelled for this fireplace
may be used.
• Venting terminals shall not be recessed into a wall or
siding.
• Horizontal venting must be installed on a level plane
without an inclining or declining slope.
There must not be any obstruction such as bushes, gar-
den sheds, fences, decks or utility buildings within 24”
(610 mm) from the front of the termination hood.

Vertical Termination
A vertical vent system must terminate no less than 12’
(3.66 m) and no more than 40’ (12 m) above the appli-
ance flue collar. A 2’ (610 mm) vertical section must be
installed before any offset. A maximum of 20’ (6.1 m)
horizontal and three (3) 90° elbows may be installed
with a minimum of 12’ (3.66 m) vertical section above
the flue collar of the unit. Refer to Page 15, Figure 26
for more information.
A vertically terminated vent system must also conform
to the following criteria:
• No more than three (3) 90° elbows may be used.
• Two (2) 45° elbows may be substituted for one (1)
90° elbow. No more than six (6) elbows may be
used.
• Vent must rise a minimum of 2’ (610 mm) before

General Information
Assembling Vent Pipes
SK8 Venting Pipes
Canadian Installations:
The venting system must be installed in accordance
with the current CSA-B149 .1 installation code.
USA Installations:
The venting system must conform with local codes and/
or the current National Fuel Gas code ANSI Z223.1/
NFPA 54.
Only venting components manufactured by CFM Cor-
poration can be used in Direct Vent systems.
NOTE: The joints of the inner pipe (flue pipe) must be
taped with 550°F or higher temperature metal adhesive
tape that meets the requirements of F.A.R. 25.853(a)
High temperature sealant milpack or stove cement
of 550°F or higher could be used instead. The joints
of The outer pipe (fresh air pipe) must be taped with
315°F or higher temperature metal adhesive tape or the
use of high temperature milpack or stove cement would
be applicable. When using the unitized 30°, 45° or 90°
elbows, apply 1/4” bead of high temperature, 550°F or
higher, sealant (milpack or stove cement) to the joint of
the inner pipe (flue pipe) and the straight section as it is
impossible to be taped. The outer pipe must be taped
with 315°F high temperature metal adhesive tape for
proper sealing.
Start by attaching the first vent pipe section to the collar
on top of the fireplace. In order to attach the first pipe
section, it may be necessary to remove the top shield.
Remove four (4) screws securing top shield, install first
pipe section and replace top shield.
Install the pipe as shown in Figure 14. When you get a
good lock, you will hear the pipe clearly snap together.
Once sections are snap-locked in place, it is extremely
difficult to get them apart. Make sure the pipe is firmly
snapped and locked together as each pipe section is
mounted. When using 45° or 90° elbows, it is accept-
able to use three (3) screws (not supplied) at the joint
between the vertical SK8 pipe and the elbow to ensure
no separation.
When installing elbows, follow the same procedure.
The joints of inner and outer elbow must be taped with
UL approved high temperature metal adhesive tape for
proper sealing. Be sure to always attach straps on up-
per elbow to a structural framing member.
For vertical installations, continue installing the pipe as
required until pipe is installed up through the ceiling. At
this point, you must install a firestop spacer.

Since it is very important that the vent-
ing 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.
NOTE: The penetration to the outside of the build-
ing or structure shall be sealed air and weather
tight.
Use of the Restrictor Plates in
Horizontal Venting Applications
The primary purpose for the vent restrictor plate is to
regain flame height under certain venting conditions as
outlined below.
The DVT38 is shipped with the fresh air plate set-
tings at #4 (this applies to both natural gas and liquid
propane) when using the horizontal starter vent kit
SK8DVSK.
Minimum clearance between vent pipes
and combustible materials is 3¹⁄₂” (89 mm)
on top, 2¹⁄₂” (64 mm) on both sides and 1¹⁄₂”
(38 mm) on the bottom.
When the vent termination exits through foundations
less than 20” (508 mm) below siding outcrop, the vent
pipe must be flush 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 of vent pipe from the flue collar of the fire-
place to the face of the outer wall.
Horizontal plane means no vertical rise exists on this
portion of the vent assembly.
NOTE: Apply high temperature sealant or UL approved
high temperature metal adhesive tape as directed on Page
12.

STEP 6
Measure the horizontal length requirement including
a 2” (50 mm) overlap, ie from the elbow to the outside
wall face plus 2” (50 mm) (or the distance required if
installing a second 90° elbow). (Fig. 23)
Always install horizontal venting on a level plane.
STEP 7
Use appropriate length of pipe sections and
install the horizontal vent sections. You may need to cut
1’ wall section to size to be flush with the outside wall.
The sections which go through the wall are packaged
with the starter kit, and can be cut to suit if necessary.

Use of Restrictor Plate
for Vertical Venting Applications
The primary purpose for the vent restrictor is to regain
flame height under certain venting conditions as
outlined below.
NOTE: The joints of the inner pipe (flue pipe) must be
taped with 550°F or higher temperature metal adhesive
tape that meets the requirements of F.A.R. 25.853(a)
High temperature sealant milpack or stove cement
of 550°F or higher could be used instead. The joints
of The outer pipe (fresh air pipe) must be taped with
315°F or higher temperature metal adhesive tape or the
use of high temperature milpack or stove cement would
be applicable. When using the unitized 30°, 45° or 90°
elbows, apply 1/4” bead of high temperature, 550°F or
higher, sealant (milpack or stove cement) to the joint of
the inner pipe (flue pipe) and the straight section as it is
impossible to be taped. The outer pipe must be taped
with 315°F high temperature metal adhesive tape for
proper sealing.
For vertically venting either propane or natural gas
units, with vertical vent heights of 12’ (3.7 m) or greater,
(measured from the top of the flue collar) the restrictor
plate as supplied with this unit should be used. (Fig.
26) Also, the fresh air restrictor plate could be adjusted
according to your vent height. (Fig. 26) Refer to Pages
20 & 21, Figures 35 & 37 for restrictor plate installation
and fresh air restrictor plate adjustment.

• Up to two (2) 30° or 45° elbows may be used within
the horizontal run. For each 30° or 45° elbow used
on the horizontal level the maximum horizontal
length must be reduced by 18” (457 mm).
Example: Maximum horizontal length
0 x 30° or 45° elbows = 10’ (3 m)
1 x 30° or 45° elbows = 8’6” (2.6 m)
2 x 30° or 45° elbows = 7’ (2.1 m)
• A minimum of an 12’ (3.7 m) vertical rise.
• Two sets of 30° or 45° elbows offsets within these
vertical installations. From 0 to a maximum of 8’ (2.4
m) of vent pipe can be used between elbows. (Fig.
29)
• SKCS8 must be used to support offsets. (Fig. 30)
This application will require that you first determine
the roof pitch and use the appropriate starter kit.
(Refer to Venting Components List)
• The minimum height of the vent above the highest
point of penetration through the roof is 2’ (610 mm).

Only glass approved by CFM Corporation
should be used on this fireplace.
1. Turn the fireplace OFF (including the pilot).
2. If the unit has been operating allow time for the
components to cool.
3. Using a Phillips screwdriver, unfasten two (2) screws
located at the top of the glass frame. (Fig. 34)
4. Tilt the glass frame at the top away from the unit.
Lift it carefully off the bottom door track and set on
padded surface.
It is necessary to periodically clean the glass. 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 the glass be
cleaned two or three times with a non-ammonia based
household cleaner and warm water (gas fireplace glass
cleaner is recommended) within the first few weeks of
operation.
After the initial cleaning process the glass should be
cleaned two or three times during each operating
season depending on the environment in the house.
Clean the glass after the first two weeks of
operation.
• The use of any non-approved replacement glass will
void all product warranties.
• Care must be taken to avoid breakage of the glass.
• Do not operate appliance with glass front
removed, cracked or broken.
• A replacement glass frame assembly (complete
with gasket) is available through your CFM
Corporation dealer and should only be installed
by a licensed qualified service person.
