Framing and Finishing

1. Choose a fireplace location and frame in accordance
with the fireplace dimensions specified on Page 3 of
this manual. When using a surround, the fireplace
must be flush to the wall. Also, allowances must
be made for drywall, tile or any other facing used
around the unit.

2. When the appliance is installed directly on carpeting,
tile or other combustible material other than wood
flooring, the appliance shall be installed on a metal
or wood platform.

3. Pull out the nail tabs which are located on each side
of the fireplace. Move the fireplace into position and
secure to the floor with screws or nails through the
holes provided in the bottom flanges of the side cas
ing. After checking unit for squareness, secure top of
fireplace to the framing with screws or nails using the
nailing tabs provided.

4. Cold climate installation recommendation: when
installing this fireplace against a non-insulated exte­rior wall or chase, it is recommended that the outer
walls be insulated to conform to applicable insulation
codes. Drywall should be installed around the unit to
prevent insulation from contacting the body.

Surround Material

When using materials around the face of the fireplace,
these materials must be suitable to withstand the tem­peratures which they will encounter. Also these materi­als must not extend out in front of the face of the unit, in
effect recessing the unit.

If the material used for surround is not flush with the
face of the unit, then the optional surround kits will not
fit properly.

It is recommended that any material used to surround

the face of the fireplace be noncombustible (i.e. ceram­ic tile, brick, natural stone, etc.). Combustible materials
such as drywall, are permissible.

76657

Materials such as cultured marble or other synthetic
materials are not recommended as they may discolor,
warp or create odor as a result of exposure to the tem­peratures of the front of the fireplace.

Temco DV1000/1200/1400 Series

When locating the vent termination, the minimum vent
clearances must be observed. (Page 10, Fig. 9)

NOTE: Local codes may require different clearances.

It is recommended that the termination not be located
within 24” (305mm) of garden sheds, fences, decks,
utility buildings or other obstructions.

Do not locate termination cap where excessive snow or
ice build up may occur. Be sure to check vent termina­tion area after snow falls and clear to prevent accidental
blockage of venting system. When using snow blowers,
make sure snow is not directed towards vent termina­tion area.

This appliance has a “special vent system”. Check
with local codes or in the absence of same, with CSA
B149.1 installation codes in Canada, or the current
National Fuel Gas Code ANSI Z223.1/NFPA 54 in the
USA, regarding special vent termination clearances.

These fireplaces are certified for use with four types of
venting systems

1. Temco 4” x 7” dia. flex vent.

2. Temco TDV series 4” x 7” dia. rigid vent.

3. Simpson Dura-Vent GS series 4” x 6⁵⁄₈” dia. vent.

4. Security Secure Vent series 4” x 6⁵⁄₈” dia. vent.
Review general venting information in this manual, and

information packed with the venting prior to starting the
installation of the fireplace.

• Termination shall not be recessed into a wall or sid­ing.

• Horizontal sections must maintain a minimum 1/4”
rise per linear foot of horizontal run.

• Combustible clearances from any horizontal vent
pipe area must be 2” (51 mm) from top of vent, and
1” (25 mm) from sides and bottom.

• Clearance to combustibles from vertical pipe surface
is 1” (25 mm).

Sidewall (General) Venting Information

Figures 15 and 16 show examples of horizontal termi­nation arrangements using two 90° elbows (Rigid Vent).

NOTE:

1. A maximum of two 90° elbows are permitted.

2. A minimum of 10’ (3 m) vertical from base of unit is
required if two 90° elbows are used.

3. Minimum distance between elbows is 2’ (610 mm).

4. Determine the permitted range of horizontal ter­mination arrangement by using chart above and
deducting 3’ (914 mm) from the maximum horizontal

distance for the second 90° elbow.

• Flex vent shall use the spacer springs as included
every foot to ensure proper vent operation.

• The 4” x 7” flex system may be used for all sidewall
applications and vertical venting up to 35’ (10.7 m).

• Flex shall be properly supported so there are no
sags in the system. Supports must be used at least
every 24” (610 mm) on horizontal section and every
36” (914 mm) on vertical. Wire or metal stripping
may be used to support the venting.

• For 4” x 7” flex, the 7” flex has an outside diameter
of 7¹⁄₂” (191 mm) and if installed in a chase the in­side diameter of the chase should be 9¹⁄₂” (241 mm)
minimum.
