IMPORTANT:
PLEASE REVIEW THE FOLLOWING CAREFULLY
Remove any plastic from 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
four (4) 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.
Proposition 65 Warning: Fuels used in gas, wood-
-
burning or oil fired appliances, and the products of
combustion of such fuels, contain chemicals known to
the State of California to cause cancer, birth defects
and other reproductive harm.

Hearth
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.
Cold climate installation recommendation:
When installing this unit against a
non-insulated exterior wall or chase,
it is mandatory that the outer walls
be insulated to conform to applicable
insulation codes.
NOTE: Never allow vapor barrier to contact the
outer casing of this fireplace or venting.
Framing and Finishing
1. Choose the unit location.
2. Place the unit into position and secure it to the floor
with 1¹⁄₂” (38 mm) screws, or nails. The holes to
secure the unit to the floor are located just behind
the access door grille on the left and right side of the
unit.
3. Frame in the fireplace with a header across the top.
It is important to allow for the finished wall face when
setting the depth of the frame.
4. Attach the fireplace to the frame using the adjust
able frame drywall strips (located behind the access
door for shipping). Preset the depth to suit the facing
material of the wall. The strips are adjustable to 1/2”
(13 mm), 5/8” (16 mm) or 3/4” (19 mm). (Fig. 4)
5. Screw through the slotted holes in the drywall strip
and into the pre-drilled holes in the fireplace side.
Measure from the face of the fireplace to the face of
the drywall strip to confirm the final depth.
-
Final Finishing
Noncombustible materials such as brick or tile may be
extended over the edges of the face of the appliance.
DO NOT cover any vent or grille panels.
If a Trim Kit is going to be installed on the fireplace, the
brick or tile will have to be installed flush with the edges
of the appliance.

TDVN Series Direct Vent Gas Fireplace
Gas Line Installation
When purging gas line, the front window
frame assembly must be removed.
1. The gas pipeline can be brought in through the rear
of the fireplace as well as the bottom. Knockouts are
provided on the bottom behind the valve to allow for
the gas pipe installation and testing of any gas connection. 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 prop
erly tinned 3/8” copper tubing, 3/8” rigid pipe or an
approved flex connector. Since some municipalities have additional local codes, it is always best to
con- sult your local authority and the National Fuel
Gas Code, ANSI Z223.1/NFPA 54 in the USA or the
CSA-B149.1 installation codes.
*Adhere to the following installation requirements in the
State of Massachusetts:
• The installer must be a licensed plumber or gas fitter.
• Flex connectors must be Massachusetts approved, cannot
exceed 36” (914 mm) in length, must be a minimum 1/2”
dia. and may not penetrate a wall.
1/2” Gas Supply
1/2” NPT X 1/2” Flare Shut-off Valve
3/8” Flex line
(from valve)
-
5. For natural gas, a minimum of 3/8” iron pipe with a
gas supply pressure of 4.5” w.c. (from the gas meter). Consult with local gas utility and ANSI Z223.1/
NFPA 54 if any questions arise concerning pipe
sizes.
6. Turn the gas supply to ‘ON’ and check for leaks. DO
NOT USE OPEN FLAME FOR THIS PURPOSE.
Use an approved leak testing solution.
7. The appliance and its appliance main gas valve
must be disconnected from the gas supply piping
system during any pressure testing of that system at
test pressures in excess of 1/2 psig (3.5KPa).
8. This appliance must be isolated from the gas supply
piping system by closing its equipment shut off valve
during any pressure testing of the gas supply piping
system at test pressures equal to 1/2 psig (3.5KPa).
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.
When using copper or flex connector use only approved
fittings. Always provide a union when using black iron
pipe so that the gas line can be easily disconnected
for burner or fan servicing . See gas specifications 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.
FP297A
Fig. 5 Typical gas supply installation.
2. The gas control inlet is 3/8” NPT. typical installation
layout for rigid pipe is shown in Figure 8.
NOTE: All models are equipped with a flex tube
with a shut off valve having a 1/2” NPT inlet. The
flex line with shut off is shipped in the control
valve compartment. Using two wrenches, tighten
the flexible tube at the shut off valve and at the
gas control
3. When using a flex connector,* use only approved fit
tings. When a union is installed, provide easy access
in its placement for servicing. Refer to gas specification for pressure details and ratings.
4. When a vertical section of gas pipe is required for
the installation, a condensation trap is needed. In
Canada see CSA-B149.1 for code details. See the
National Fuel Gas Code ANSI Z223.1/NFPA 54 in
the USA.

General Information on Assembling Vent Pipes
* Be sure the vent is actually crushed before proceeding. Apply a tug to be sure the vent will not slip off the
collars.
Repeat process with 7” flex vent pipe. The same procedure must be performed on the vent side.
Only venting components manufactured by CFM Corporation can be used in Direct Vent systems.
Flex Vent Pipes
Before joining the flex vent pipe to the unit, apply a
bead of high temperature sealant* (provided) to the 4”
pipe exiting the fireplace. Secure flex vent pipe in place
with a hose clamp (provided).
*Be sure the flex pipe overlaps at least 1” (25 mm) onto
the collars of the fireplace and termination. If the termination has an internal bead, be sure to overlap and
secure 1” (25 mm) past the bead.

Twist Lock Pipes
TDVN Series Direct Vent Gas Fireplace
When using CFM Corporation twist-lock pipe it is not
necessary to use sealant on the 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, then while bringing the ends together, twist 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 prior to assembly.

How to Use the Vent Graph
Vertical dimension from the floor of the fireplace to
the center of the horizontal vent pipe
Horizontal dimension from the outside face of the wall to
the center of the fireplace vent flange
Sidewall vent graph showing the relationship between vertical
and horizontal dimensions for a Direct Vent flue system.
Fig. 12 Sidewall venting graph. (Dimensions in feet)
The vent chart should be read in conjunction with the
following vent installation instructions to determine the
relationship of the vertical and horizontal dimensions of
the vent system.
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 (Fig. 12),
locate the point intersecting 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’ (3.4 m) the horizontal run to the face of the outer
wall must not exceed 14’ (4.3 m).
Example B:
If the vertical dimension from the floor of the unit is 7’
(2.14 m), the horizontal run to the face of the outer wall
must not exceed 8¹⁄₂’ (2.6 m).
20007636
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 vent graph showing the relationship between vertical and horizontal side wall venting will help to determine the various dimensions allowable.
Minimum clearance between vent pipes
and combustible materials is one 1” (25
mm) on top, bottom and sides unless otherwise noted.
When the vent termination exits through foundations
less than 20” (508 mm) 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 of vent pipe from the flue collar of the fireplace to
the face of the outer wall.

Fig. 13 Support straps for horizontal runs.
Horizontal plane means no vertical rise exists on this
portion of the vent assembly.
• The maximum number of 90° elbows per side wall
installations is three (3).
• If a 90° elbow is fitted directly onto the fireplace
flange the maximum horizontal vent run before the
termination or a vertical rise is 36” (914 mm).
• If a 90° elbow is used in the horizontal vent run
(level height maintained) the maximum horizontal
vent length is reduced by 36” (914 mm). This does
not apply if the 90° elbows are used to increase or
redirect a vertical rise.
Example: According to the chart the maximum
horizontal vent length in a system with a 7.5’ (2.3 m)
vertical rise is 20’ (6 m) and if a 90° is required in
the horizontal vent it must be reduced to 17’ (5.2 m).
In Figure 16, Dimension A plus B must not be
greater than 17’ (5.2 m).
1 x 90° elbow in horizontal plane = 3’ (914mm)
FP1238
Fig. 15 Maximum vent run with elbows.
• The maximum number of elbow degrees in a system
is 270°. (Fig. 16)
Example:
Elbow 1 = 90°
Elbow 2 = 45°
Elbow 3 = 45°
Elbow 4 = 90°
Total angular variation = 270°
1 + 2 + 3 + 4 = 270°
Fig. 14 Maximum horizontal vent run.
• 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” (457 mm). This does not apply if the 45° elbows
are installed on the vertical part of the vent system.

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.
NOTE: When using flex vent, the opening will have to
be measured according to the 1” (25 mm) rise in 24”
(610mm) vent run.
