OPTIONAL GAS LINE INSTALLATION

OPTIONAL GAS LINE INSTALLATION
Permanently Located (Sited) Homes Only

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.

A gas line may be installed for the purpose of installing a vented 

or vent free appliance available through your local distributor. Use 

only a 1/2" black iron pipe and appropriate fittings. When installing 

a gas line, a shutoff valve designed for installation outside appliance 

is recommended.

1.  Remove knockout indentation on refractory or firebrick wall 

located above the 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 28

).

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 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 29

).

 

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 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 APPLI-

ANCE IF A LEAK IS DETECTED. LEAK TESTING SHOULD 

BE DONE BY A QUALIFIED SERVICE PERSON.

     WARNING

Do not operate an unvented gas log set in this fireplace 

with the chimney removed.

     WARNING

If the fireplace has been used for wood burning, the 

firebox and chimney must be cleaned of soot, creosote 

and ashes by a qualified chimney cleaner. Creosote 

will ignite if heavily heated.

     WARNING

When using a decorative vented gas log, the damper 

must be removed or permanently locked in the fully 

open position and the glass doors must be in the fully 

open position.
