IMPORTANT: The glass must be allowed to warm slowly and evenly. The tempered glass will withstand a gradual temperature rise to 550 degrees Fahrenheit, which is more than a normal fire will generate. Such materials as pitch/wax laden logs, very dry mill end lumber, and large amounts of paper or cardboard boxes can create an excessively hot fire and should not be burned in this fireplace. Always keep the fire well back from the doors and never allow flames to contact the glass.

WARNING: Fireplaces equipped with glass doors should be operated only with door fully opened or doors fully closed. Doors, if left partly open, may draw gas and flame out of the fireplace opening creating risks of both fire and smoke.

CLEANING THE GLASS: Clean the glass with any commercial glass cleaner or soap and water. DO NOT use any abrasive material to clean the glass. DO NOT clean the glass with any cool water if the glass is still hot from the fire.

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.

A gas line may be installed for the purpose of installing a vented or vent-free gas appliance available through your local distributor. Use only ½ inch black iron pipe and appropriate fittings. When installing a gas line, a shut-off valve designed for installation outside the appliance is recommended.

STEP 1: To install, remove the knockout indentation on the refractory, (or firebrick), wall located approximately 2 inches above the refractory hearth floor. The knockout indentation must be firmly tapped with any solid object until it is released. Remove fragmented portions of refractory (see figure 22).

Figure 22

STEP 2: Remove gas line cover plate on rear of fireplace and pull out insulation from gas line conduit sleeve. Save insulation for reuse.

STEP 3: Run a ½ inch black iron gas line into the fireplace through the gas line conduit sleeve. Provide sufficient gas line into fireplace chamber for fitting connection (see figure 23).

NOTE: Secure incoming gas line to wood framing to provide rigidity for threaded end.

Figure 23

STEP 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.

The gas pipe is intended for connection to an unvented (vent- free) or a decorative gas appliance (vented gas log).

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 a 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 APPLIANCE IF A LEAK IS DETECTED.

If you wish to install an unvented (vent-free) gas log set, ONLY UNVENTED GAS LOG SETS WHICH HAVE BEEN FOUND TO COMPLY WITH THE STANDARD FOR UNVENTED ROOM HEATERS, ANSI Z21.11.2, ARE TO BE INSTALLED IN THIS FIREPLACE.

NOTE: A DESA hood must be installed when using an unvented gas log set (see accessories on page 10).

WARNING: DO NOT OPERATE AN UNVENTED GAS LOG SET IN THIS FIREPLACE 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 Appliances for Installation in solid fuel burning Fireplaces, ANS Z21.60-1996, Z21.84 or RGA 2-72, and shall also be installed in accordance with the National

Fuel Gas code, ANS Z223.1-1996.

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 highly heated.

WARNING: WHEN USING A DECORATIVE VENTED GAS LOG, THE DAMPER MUST BE REMOVED OR PERMANENTLY LOCKED IN THE FULLY OPENED POSITION.
