Installing A Gas Line; Cold Climate Installations - Temco TLC39-22 Installation Instructions Manual

Figure 21

INSTALLING A GAS LINE

All Temco fireplaces are designed to accept a 1/2" gas line.
The gas appliance must be certified, listed or approved for
installation in a solid fuel fired fireplace by a nationally
recognized certification agency. A gas appliance must be
installed and operated in accordance with the instructions
provided by the appliance manufacturer 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 22.
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 attach to the line. Finish installation by
either 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 cement.
CAUTION: When using a decorative appliance, the
fireplace damper must be set In the fully open position.

INSTALLATIONS
NOTE: THE FOLLOWING INFORMATION ON SEALING
AND INSULATING THE FIREPLACE IS LEFT UP TO THE
DISCRETION
MANUFACTURER. THESE STEPS ARE REQUIRED FOR
SAFE INSTALLATION OF THE FIREPLACE SYSTEM.
The insulation and sealing of the enclosure around the
fireplace is very important 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.
INSULATION OF THE FIREPLACE ENCLOSURE
When in a chase, or on an outside wall, the fireplace
enclosure can be insulated like any other outside wall.
Insulation can be installed on the outside walls and the wall
above the fireplace. In chase installations, 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 maintained. Lining the interior walls of the fireplace
enclosure with gypsum wallboard will further reduce cold air
infiltration. (See figure 23.)
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 important 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
beneficial to insulate between the floor joists.
CAUTION: When Installing a fireplace in an insulated
enclosure, be sure to maintain all marked air spaces.
SEAL SEAMS
Figure
Seal between the fireplace and finishing materials. Use high
temperature caulk. See figure 24 for the details of sealing
spaces between the fireplace and finishing materials. Note
the small amount of insulation installed across the top of the
fireplace and down the sides as a backing for the caulk.
DO NOT BLOCK INLET HOLES AT BASE OF CHIMNEY
SYSTEM.
