Note:
Before you proceed, make sure your gas supply is turned off.
Use only a 1/2" black iron pipe and appropriate fittings.

-
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
24).
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 25).
Note:
Secure incoming gas line to wood framing to provide rigidity for

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.
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.
