A gas line or gas log lighter may be installed for the purpose of
installing a vented or vent-free decorative gas appliance incorporat-
ing an automatic shutoff device and complying with the Standard
for Decorative Gas Appliances for Installation in Vented Fireplaces,
ANSI Z21.60 or American Gas Association draft requirements for
Gas Fired Log Lighters for Wood Burning Fireplaces, Draft NO. 4
dated August, 1993.
If you wish to install an unvented (vent-free) gas log set, only
unvented gas log sets which have been found to comply with the
standard for unvented room heaters, ANSI Z21.11.2 are to be installed
in this fireplace.
Gas line hook up should be done by your supplier or a qualified
service person.
Note:
Before you proceed, make sure your gas supply is turned off.
Use only a 1/2" black iron pipe and appropriate fittings.
1. Remove knockout indentation on refractory or firebrick wall
located above refractory hearth floor. Knockout indentation must
be firmly tapped with any solid object, such as a 1/2" dowel, until
it is released. Remove fragmented portions of refractory (see
Figure 21).
2. Remove gas line cover plate located on either side of fireplace and
pull out insulation from gas line conduit sleeve. Save insulation
for reuse.
3. Run a 1/2" black iron gas line into fireplace through rear at
gas line conduit sleeve (if using a raised platform, add height).
Provide sufficient gas line into fireplace chamber for fitting
connection (see Figure 22).
Note: Secure incoming gas line to wood framing to provide rigidity
for threaded end.
4. Repack insulation around gas line and into sleeve opening. Seal
any gaps between gas line and refractory knockout hole with
refractory cement or commercial furnace cement. Install gas
appliance or cap off gas line if desired.
CAUTION: All gas piping and connections must
be tested for leaks after installation is completed.
After ensuring that gas valve is on, apply soap and
water solution to all connections and joints. Bubbles
forming show a leak. Correct all leaks at once. DO
NOT USE AN OPEN FLAME FOR LEAK TESTING AND
DO NOT OPERATE ANY APPLIANCE IF A LEAK IS
DETECTED. LEAK TESTING SHOULD BE DONE BY A
QUALIFIED SERVICE PERSON.
Note:
An IHP hood must be installed when using an unvented gas
log set (see Accessories on page 20).
WARNING: Do not operate an unvented gas log
set in this fireplace with chimney removed.
