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 the
refractory hearth floor. The 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 19).
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. Replace screws.
3. Run a 1/2" black iron gas line into the
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
