INSTALLING A GAS LINE
All Temco fireplaces are designed to accept a 1/2" gas line
for a decorative gas appliance complying with Z21.60 Stan-
dard for decorative gas appliances for installation in vented
fireplaces. The decorative appliance must be installed in ac-
cordance with its installation instructions and the National
Fuel Gas Code ANSI Z223.1. The fireplace has a factory
installed tube for insertion of the gas line. Refer to page 4
for gas line inlet location.
NOTE: A minimum 1/2" clearance from
the gas pipe must be maintained within
4" of the fireplace, (see figure 21).
To install the gas line, use a hammer
and punch gently to knock a hole
through the refractory at the emboss.
Remove the insulation from the inlet
tube. Run the line to just outside the gas
inlet hole of the fireplace. Slide a 1/2"
gas line nipple through the tube and at-
tach to the line. Finish installation by ei-
ther capping gas line inside fireplace or
by attaching an approved gas appliance
in accordance with its installation
instructions. Re-install insulation around
the gas line to seal between the gas line
and gas conduit. Seal around the gas
line and the refractory with refractory ce-
ment.
CAUTION: When using a decorative
appliance, the fireplace damper must
be set in the fully open position.
RECOMMENDED COLD
CLIMATE INSTALLATIONS
The insulation and sealing of the enclo-
sure around the fireplace is very impor-
tant in cold climates. If the enclosure is
insulated and sealed properly, you can
avoid future cold air problems. The time
taken to install the firebox correctly is
well worthwhile. The following steps are
recommended to stop potential cold air problems.
INSULATION OF THE FIREPLACE ENCLOSURE
When in a chase or on an outside wall, the fireplace enclo-
sure should be insulated like any other outside wall. Insula-
tion should be installed on the outside walls and the wall
above the fireplace. It is also recommended in chase instal-
lations to install a firestop at the first ceiling level above the
fireplace and seal the remaining area with either sheet
metal or 1/2" gypsum wallboard. Insulation may then be
installed above the sheeting material. Required
clearances to the chimney pipe must be main-
tained. Lining the interior walls of the fireplace en-
closure with gypsum wallboard will further reduce
cold air infiltration, (see figure 22.)
INSULATE TO SEAL UNDER THE FIREPLACE
Insulating under the fireplace is beneficial for
installations on a concrete slab. The fireplace
should be placed on insulating board. It is impor-
tant that a hard, rigid surface be maintained, so do
not use fiberglass insulation for this purpose. In a
chase that cantilevers outside the house, it is bene-
ficial to insulate between the floor joists.
CAUTION: When installing a fireplace in an in-
sulated enclosure, be sure to maintain all
marked air spaces.
SEAL SEAMS
Seal between the fireplace and finishing materials.
Use high temperature caulk. See figure 23 for the
details of sealing spaces between the fireplace and
finishing materials. Note the small amount of insu-
lation installed across the top of the fireplace and
down the sides as a backing for the caulk.
