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 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 ANYAPPLIANCE IF A LEAK IS DETECTED. LEAK TESTING SHOULD BE DONE BYA QUALI- FIED SERVICE PERSON.

WARNING: Do not operate an unvented gas log set in this fire- place with the chimney removed.

If you install a decorative gas appliance (vented gas log), the decorative gas appliance must comply with the Standard for Decorative Gas Appliance for Installation in Solid Fuel Burning Fireplaces, ANS Z21.60, Z21.84 or RG 2-72and shall also be installed in accor- dance with the National Fuel Gas Code, ANSI 7223NFPA 54 latest edition.

WARNING: If the fireplace has been used for wood burning, the firebox and chimney must be cleaned of soot, creosote and ashes be a qualified chimney cleaner. Creosote will ignite if heavily heated.

WARNING: When using a decorative vented gas log, the damper must be removed or per- manently locked in the fully open positionandtheglassdoorsmust be in the fully open position.
