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 appropri-
ate fittings.
1. Remove knockout indentation on refrac-
tory or firebrick wall located above refrac-
tory 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 insula-
tion 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 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 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 OPER-
ATE ANY APPLIANCE IF A LEAK
IS DETECTED. LEAK TESTING
SHOULD BE DONE BY A QUALI-
FIED SERvICE PERSON.

unvented gas log set in this fire-
place with the chimney removed.
