WARNING: Check with your electronics manufacturer
before installing a television or other electronic device above this fireplace.
This appliance may be installed in an aftermarket
permanently located, manufactured home or 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 used.
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, woodburning or oil fired appliances, and the products of

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
Figures 3a and 3b.
The fitting of a bay window trim kit does not effect
the distances and reference points referred to in the

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 noninsulated 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.

TDVDSN 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” (914mm) in length, must be a minimum 1/2”
dia. and may not penetrate a wall.
1/2” Gas Supply
1/2” NPT X 3/8” Flare Shut-off 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.
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.
3/8” Flex line
(from valve)

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
fittings. 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.
EB-1 Electrical Box
The fireplace, when installed, must be elec-
trically connected and grounded in accordance with local codes or, in the absence
of local codes, with the current CSA C22.1
Canadian Electrical Code.
For USA installations follow local codes
and the national electrical code ANSI/NFPA
No. 70.
It is strongly suggested that the wiring of
the EB-1 Electrical Junction Box be carried
out by a licensed electrician.
Ensure that the power to the supply line
has been disconnected before commencing this procedure.

Twist Lock Pipes
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. 10 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. 10),
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).
12
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 fire
place to the face of the outer wall.

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

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. 15) 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”

Secure the termination to the wall with screws provided and caulk around the wall plate to weatherproof.
(Fig. 20) As an alternative to screwing the termination
directly to the wall you may also use expanding plugs
or an approved exterior construction adhesive. You
may also attach the termination with screws through
the inner body into the 4” (102 mm) vent pipe however
for this method you must extend the 4” (102 mm) pipe
approximately 6” (152 mm) beyond the outer face of the
wall.

Below Grade Installations
When it is not possible to meet the required vent terminal clearances of 12” (305 mm) above grade level a
snorkel vent kit is recommended. It allows installation
depth of down to 7” (178 mm) 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.
If installing a snorkel a minimum 24” (610 mm) vertical
rise is necessary. The maximum horizontal run with
the 24” (610 mm) vertical pipe is 36” (914 mm). This
measurement is taken from the collar of the fireplace
(or transition elbow) to the face of the exterior wall.
Refer to the Sidewall Vent Graph for extended
horizontal run if the vertical rise exceeds 24” (610 mm).
1. Establish vent hole through the wall. (Fig. 15)

Glass Cleaning
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 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) 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.
Do not clean glass when hot.
Do not use abrasive cleaners.
Do not strike or slam glass.

Installation of Logs, Lava Rock & Ember Material
Unpack the logs from packaging and remove each log
from its wrapping materials.
The logs are fragile and should be handled
with care. Keep the packaging material out
of the reach of children and dispose of the
material in a safe manner.
The embers supplied with your fireplace
are made from platinum coated embers
and should be handled carefully. Wash
your hands immediately after touching to
avoid irritation. The embers must be placed
correctly in order to function properly.
Log Installation
Attention: Glass door should be removed when install-
ing logset and prior to lighting the unit.
1. Remove glass door (Refer to “Window Frame).
2. Remove logs from carton and inspect. Refer to Fig
ure 37.
3. Rear log should be installed onto rear log supports.
Match up slots on rear of log with the vertical log
bracket tabs. Push log back as far as it will go.
4. The center log should be placed on the center log
supports, slots aligned with tabs and log placed rearward.
5. Top twigs can then be placed in their designated po
sitions provided with pins on back logs and grooves
on the center log.
6. Place platinum embers loosely along top surface
of burner along entire length of ported area of front
burner. DO NOT place embers on back portion of
burner. Use individual pieces of embers no larger
than dime size, about 1/16” thick (fluffed up thickness). Use a single layer of embers and DO NOT
overlap pieces. Ember material should be fluffed up
and not compressed. When properly placed, all embers will glow red. Adding more embers than necessary will detract from appearance.

Unit Adjustment
Once installed, the unit should be operated at least
three (3) times to ensure that all is in working order.
NOTE: Manufacturing oils will smoke during initial firing
of appliance. Open windows for ventilation.
Before leaving, the installer should make the following
checks:
Btu Input/Gas Pressure
The fireplace input is marked on the Rating Plate. The
gas inlet pressure specified in Table 1 is the pressure
where the field-installed gas line connects to the gas
control. This is measured at the inlet test port (1/8” NPT
plugged port) on the gas valve in the appliance. Ensure
that pressure is as shown in Table 1.
The manifold pressure is controlled by a regulator
built into the gas control and should be checked at the
pressure outlet test port located on the body of the gas
valve.
The pressure should be checked with the appliance
burning on high (highest setting) and all other gas appliances turned on. One must then read the manometer
and if pressures are not as specified in Table 1, then the
inlet pressure must be adjusted.
The appliance and its individual shut-off valve must be
disconnected from the gas supply piping system during
any pressure testing of the system at test pressures in
excess of 1/2 psig (3.5 KPa).
Pressure ranges are as listed below:
Table 1
Gas Supply Pressure (inches w.c.)
Minimum Normal Maximum
Natural Gas 4.5” 7.0” 14.0”
LP (Propane) 10.8” 11.0” 14.0”
Manifold Pressure (inches w.c.)
Normal (HI) Normal (Low)
Natural Gas 3.5” 1.6”
LP (Propane) 10.0” 6.3”
High Altitude
When installing this fireplace at an elevation between
0 and 2000 feet (0 - 610m) in the USA and 0 and 4500
feet (0 - 1370m) in Canada the input rating does not
need to be reduced.
When installing this fireplace at an elevation above
2,000 feet (in the United States), it may be necessary to
decrease the input rating by changing the existing burner orifice to a smaller size. Input should be reduced
four percent (4%) for each 1,000 feet above sea level,
unless the heating value of the gas has been reduced,
in which case this general rule will not apply. To identify
the proper orifice size, check with the local gas utility.
When installing this fireplace at an elevation above
4,500 feet (in Canada), check with local authorities.
Consult your local gas utility for assistance in determining the proper orifice for your location.
Main Burner
The main burner should be allowed to operate for 15 to
20 minutes before making any adjustment to the burner.
The air shutter on the right front of the main burner
should be adjusted so that there are no orange/red
flames with dark sooty looking tips. A luminous yellow
flame with blue base is what is acceptable.
For burner air shutter settings see Air Shutter Settings
chart. (Page 28)
If there is too much primary air then the flame will be
very blue with yellow tips and smaller flame height.
If there is too little primary air then the flame will be yellow with orange/red tips on the back flames with dark
sooty elongated tips. In this condition the glass and logs
could show signs of soot accumulation within 10 to 20
minutes.

Maintenance
TDVDSN Series Direct Vent Gas Fireplace
Motor and Blower for Fan Kit (optional)
This motor has been factory oiled and under normal
operating conditions should not require oiling.
WARNING: Ensure the power is turned off to
the fireplace before servicing.
Cleaning
This unit should be cleaned and serviced by a Qualified
Gas Technician at least annually. More frequent cleaning may be necessary if pet hair accumulates, dust and
lint are present, or if the unit is located in a high traffic
area. A Qualified Agency is defined in the Gas Code.
Cleaning should include burner tubes, orifice/injectors
(refer to section B.3 National Fuel Gas Code) and logs.
It is recommended that any sediment traps in the gas
line be emptied and cleaned at this time. (Refer to Section 3.7.2 National Fuel Gas Code)
Burner, Firebox and Logs
CAUTION: Before cleaning or moving logs or
other parts of the unit, be sure to read the section on important safeguards.
Cleaning should be done before the logs are used each
year and after long periods of non-use. All cleaning
should be carried out when the appliance is cold.
Cleaning will be required under normal use. Dusting the
front grate or the control knob panel may be required
occasionally. Do not use any cleaning fluids to clean the
logs or any other part of the appliance.
If the flames show any unusual shapes or behavior, or if
the burners fail to ignite properly, then the burner holes
may require cleaning. If this occurs, contact your nearest dealer to get the appliance serviced.
Alternatively, the appliance can be cleaned by removing
all the logs. Handle the logs gently so as not to damage
them. Always lift each log by holding it carefully at each
end.
After the logs are removed allowing access to the burner area, use a vacuum cleaner to carefully remove dust
and loose particles from the base, logs and from around
the burners. Gloves are recommended to prevent the
ceramic fibers that compose the logs from pricking
your skin. If the skin is pricked, wash gently with soap
and water. Use extreme caution in cleaning around the
pilot . The spark igniter should not be moved or altered
from the original factory setting. The burner should be
placed back into its original locked and secure position
after cleaning and servicing(proper location of burners
are critical). NOTE: All replacements and repairs should
be performed by a qualified technician (contact your
nearest dealer). After cleaning and/or repairs, follow
instructions for positioning of logs as illustrated on Page
22.
Glass
It will be necessary to clean the glass periodically. During startup it is normal for condensation to form on the
glass and cause dirt, lint, etc., to adhere to the inner
surface of the glass. There also will be a film deposited
on the glass during the initial use of the fireplace due
to initial curing of the paint. It is recommended that the
glass be cleaned with a non-abrasive household cleaner and warm water. Be sure to rinse and dry the glass
well as not to leave any marks. It may be necessary to
clean the glass two to three times a season depending
on use of the fireplace.

Fan Kits
FK24 Fan Assembly
This auxiliary fan system increases the efficiency of the
circulation of the heating air.
The FK24 fan kit allows variable speed control of the
circulation fan and also incorporates a heat sensor in
the circuit.
Specifications
115 Volt / 60Hz / 56 Watts
Maintenance
The fan itself does not require regular maintenance,
however periodic cleaning of the fan and the
surrounding area is required.
Check the area under the control door (lower louvre
assembly) and in front of the fan and wipe or vacuum this
area at least once a month during the operating season.
Installation
The fan assembly and other components are supplied
fully wired eliminating the need for a licensed electrician
to carry out the installation.
If hard wiring the fan using Method B (following), we
strongly recommend the use of a licensed electrician.
1. Open the lower louvre assembly. Maneuver the fan
& bracket assembly around the gas valve and lines
to locate the unit onto the screw studs on the back of
the fireplace.
2. Install the thermal sensor under the bottom of the of
the firebox, locating it over the two 10 mm studs and
secure it with nuts.
3. Locate the fan speed control unit. This can be fitted
behind the lower louvre assembly as in Figure 52
or located remotely in a conveniently located wall
mounted electrical box. Remote location of the
speed control will require suitable extension of the
component wiring.
4. The power supply may be connected in two ways:
Method A
Route the 6’ lead fitted to the unit to a conveniently
located wall socket.
Method B
The EB-1 receptacle box (Pt. # ZA1200) may be
hard wired into the house supply. The fan lead is
then plugged into the EB-1 box. For instruction on
wiring the EB-1 Electrical Junction Box see the
earlier chapter in the Installation section of this
manual.
