IMPORTANT:

PLEASE READ THE FOLLOWING CAREFULLY

Remove any plastic from trim 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 Temco Fireplace Products gas
fireplace to give off some odor the first time it is
burned. This is due to 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 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.

WARNING: When purging the gas line, the glass
front must be removed.

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
casing. 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.

NOTE: Never let vapor barrier contact the outer
case of this fireplace or venting.

5. Drywall can be extended flush on the bottom, top
and to the outermost part of the sides of the fire­place.

6. Noncombustible materials such as brick and tile can
be extended across the face of the fireplace. If
brass trim kit is going to be installed, brick and tile
will have to be installed flush with the front of this
appliance.

Hearth

A hearth is not mandatory, but is recommended for
aesthetic purposes. We recommend a noncombustible
hearth projecting 12” (305mm) or more in front of the
fireplace.

Although a hearth is not mandatory, (as surface tem­peratures of combustibles are tested) surface tempera­tures of flooring (carpeting, tiel, varnish, etc.) may
reach a point where damage to some surfaces may
result.

For example:

• carpeting may buckle and discolor

• vinyl tile may discolor and unglue

• varnishes, waxes, etc. on wood flooring may dis-

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.

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 it’s 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.

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
ANSI223.1/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 1/2psig (3.5 KPa).

8. The 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 or less than
1/2psig (3.5KPa).

NOTE: The gas line connection may be made of 3/8"
minimum rigid pipe, 3/8” minimum copper pipe or an
approved flex connector. Since some municipalities
have additional local codes, it is always best to consult
your local authorities and the current CSA-B149.1
installation code in Canada or National Fuel Gas Code
ANSI Z223.1/NFPA 54 in the U.S.A.

Flex Venting

•

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’ (10.7m).

• Flex shall be properly supported so there are no

sags in the system. Supports must be used at least
every 24” (610mm) on horizontal section and every
36” (914mm) 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” (191mm) and if installed in a chase the
inside diameter of the chase should be 9¹⁄₂”
(241mm) minimum.

• Lengths of co-axial flex may be joined together

using a flex connector kit (GFPVCK) only, maximum
1 kit per installation.

An extension collar is included with side wall cap kits
to simplify the connection of the flex pipe to the fire­place. Refer to Page 13, Figure 22.

ATTENTION: Spacer springs must be installed when
installing flexible venting systems.

Wrap spacer spring around flex flue pipe and overlap
spring ends approximately 2” (610mm). Tie one end
over the other like a shoelace tie, then reverse direc­tion of spring ends. Lift up hooped spring and slide
both spring ends underneath hooped spring. Spring
spacers should be spaced at approximately 12”
(305mm) intervals for the length of pipe system. Once
the springs are placed around the flue pipe, slide the
flue section with spacer springs into the outer flex pipe.

Sidewall (Horizontal) Venting

For side wall (Horizontal) venting, this appliance is
approved for use with a 7" x 4" flexible venting system
with spacers.

Clearance to combustible material from the pipe is 1"
(25mm). Sides and bottom, 2” clearance from the top.
Note: O.D. of pipe is 7¹⁄₂" (191mm).

Horizontal Vent Kits
♦ CDV-HSK (Round Termination Cap)

The vent starter kit contains the following:

• Horizontal termination

• Wall thimble

• 36" of 7" x 4" flex with spacers and clamps.

• Extension collar

♦ HFTK (Trapezoid Termination Cap)

The vent starter kit contains the following:

• Horizontal termination

• Wall thimble

• Extension collar

NOTE: HIGH WIND AREAS All termination caps are
tested and certified for wind conditions up to 40 mph
(64 k/h).

A Vinyl Extension Frame Kit No. VEF is required for all
installations where vinyl siding is used with the HFTK
Kit or HSQ47 Horizontal Vent Termination. If a Vinyl
Extension Frame Kit No. VEF is used, measure to
outside surface of wall without siding and add 2 addi­tional inches (51mm) to the venting length.

A brick extension kit No. BEF is available to extend the
horizontal vent terminal HSQ47 or HFTK kit terminal
beyond the brick surface. If the BEF extension is used,
measure to the outside surface of the framed wall and
add 4 additional inches to the venting length.

2. Assemble wall thimble with thimble extension flange
to top. Mate thimble to wall plate with the four tabs
provided. Bend tabs over to secure. (Fig. 19)

3. Install the wall thimble assembly through the framed
opening so the firestop plate is on the interior wall.
(Fig. 20) Telescope section should extend all the
way through wall.

Telescope Extension

Flex Vent Offsets

Each installation assumes the use of (1) 45° (bend)
starting off top of unit.

To determine the amount or length of flex vent you
need for a given installation, add the total offset dimen­sion to the total rise needed. Then add 1 ft. (305mm)
for every 45° bend and/or 2’ (610mm) for each 90°
bend.

No more than (4) 90° and (2) 45° offsets are to be used
per installation. Vent terminal cap location should be in
accordance with the Venting Graph chart and the
Vertical Termination Location information.

1. Measure the total wall thickness. Determine whether
or not the thimble extension is needed. If the com­bustible wall depth is over 5” (127mm), the exten­sion should be used. (Fig. 19)
