OPTIONAL GAS LINE 

INSTALLATION

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 appropriate 

fittings. 
1.  Remove knockout indentation on refractory 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 insulation 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 (see Figure 20, page 12). 

Note

:  Secure  incoming  gas  line  to  wood 

framing to provide rigidity for threaded end.

ment or commercial furnace cement, Install the
