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 appropri-
ate fittings.
1. Remove knockout indentation on refracto-
ry 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 insu-
lation from gas line conduit sleeve. Save
insulation for reuse.
3. Run a 1/2" black iron gas line into fire-
place 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 com-
pleted. 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.
