GAS LINE INSTALLATION
WARNING: A qualified service person must connect
heater to gas supply. Follow all local codes.
IMPORTANT:
See Connecting to Gas Supply in your log set owner’s
manual for details on gas hookup.
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 lo-
cated 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
18).
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. Replace screws.
3. Run a 1/2" black iron gas line into fireplace through the 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 19).
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 the gas appliance or
cap-off gas line if desired.
A gas line or gas log lighter may be installed for the purpose of installing
a vent-free decorative gas appliance incorporating an automatic shutoff
device and complying with the Standard for Decorative Gas Appliances
for Installation in Vented Fireplaces, ANSI Z21.60 or American Gas As-
sociation draft requirements for Gas Fired Log Lighters for Wood Burning
Fireplaces, Draft No. 4 dated August, 1993.
When installing 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.
CAUTION: All gas piping and connections must be
tested for leaks after the installation is completed.
After ensuring that the 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.
