Typ. Figure 28 - Fireplace Facing (Your Fireplace May Vary from Illustration) 24" Min. 24" Min. Figure 27 - Multiple Chase Installation Optional Gas Line Installation WARNING: A qualified service person must connect fireplace to gas supply. Follow all local codes. NOTICE: 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 decorative gas appliance available through your local distributor. Use only gas piping approved by local codes. When installing a gas line, a shutoff valve designed for installation outside the appliance is recommended. The gas pipe is intended for connection to a decorative gas appliance that operates using natural or propane/LP gas only. This appliance must have an automatic shutoff device and must comply with the Standard for Decorative Gas Appliances for Installation in Vented Fireplace, ANSI Z21.60-1990. ONLY UNVENTED GAS LOG SETS WHICH HAVE BEEN FOUND TO COMPLY WITH THE STANDARD FOR UNVENTED ROOM HEATERS, ANSI/IAS/AGA Z21.11.2, ARE TO BE INSTALLED IN THIS FIREPLACE. Use only a 1/2" black iron pipe and appropriate fittings. 1. Remove knockout indentation on refractory or firebrick wall located approximately 2" above 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 29). 2. Remove gas line cover plate located on rear of fireplace and pull out insulation from gas line conduit sleeve. Save insulation for reuse. 3. Run gas line into fireplace through the rear at 11 1/4" from floor and through gas line conduit sleeve (if using a raised platform, add height). Provide sufficient gas line into fireplace chamber for fitting connection (see Figure 30). 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 APPLIANCE 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.

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. Note: An appropriate DESA hood (see Replacement and Accessory Parts, page 15) must be installed when using an unvented gas log set. Operation and Maintenance Guidelines Glass Doors Bi-fold glass doors are optional with this fireplace. Check with your local distributor for availability. To install glass doors, refer to installation instructions that are included with kit. When fireplace is in operation, doors must be fully open or fully closed position only or a fire hazard may be created (see Figure 31). A fireplace equipped with glass doors operates much differently than a fireplace with an open front. A fireplace with glass doors has a limited amount of air for combustion. Excessive heat within the fireplace can result if too large a fire is built or if combustion air gate is not completely open. The following tips should be followed to assure that both the fireplace and glass door retain their beauty and function properly. • Both the flue damper and glass doors must be fully opened before starting fire. This will provide sufficient combustion air and maintain safe temperatures in firebox. • The glass must be allowed to warm slowly and evenly. The tempered glass will withstand a gradual temperature rise to 550° F, 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. 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...
