Louver Firebox Top Sheet Metal Screws Hood Figure 3 - Assembling Hood Air for Combustion and Ventilation WARNING: This fireplace shall not be installed in a confined space or unusually tight construction unless provisions are provided for adequate combustion and ventilation air.
AIR FOR COMBUSTION AND VENTILATION Continued Confined and Unconfined Space The National Fuel Gas Code, ANSI Z223.1/NFPA 54 defines a confined space as a space whose volume is less than 50 cubic feet per 1,000 Btu per hour (4.8 m3 per kw) of the aggregate input rating of all appliances installed in that space and an unconfined space as a space whose volume is not less than 50 cubic feet per 1,000 Btu per hour (4.8 m3 per kw) of the aggregate input rating of all appliances installed in that space.
AIR FOR COMBUSTION AND VENTILATION Continued Ventilation Air From Inside Building This fresh air would come from an adjoining unconfined space. When ventilating to an adjoining unconfined space, you must provide two permanent openings: one within 12" of the ceiling and one within 12" of the floor on the wall connecting the two spaces (see options 1 and 2, Figure 4). You can also remove door into adjoining room (see option 3, Figure 5). Follow the National Fuel Gas Code, ANSI Z223.1/NFPA 54, Section 5.
INSTALLATION Continued WARNING: Never install in a bedroom or bathroom. Any heating product with a Btu/Hr rating over 10,000 cannot be used in a bedroom. CAUTION: This fireplace creates warm air currents. These currents move heat to wall surfaces next to fireplace. Installing fireplace next to vinyl or cloth wall coverings or operating fireplace where impurities (such as, but not limited to, tobacco smoke, aromatic candles, cleaning fluids, oil or kerosene lamps, etc.
INSTALLATION Built-In Fireplace Installation Continued CAUTION: If you install the fireplace in a home garage • fireplace pilot and burner must be at least 18" above floor. • locate fireplace where moving vehicle will not hit it. For convenience and efficiency, install fireplace • where there is easy access for operation, inspection, and service • in coldest part of room An optional blower kit is available from your dealer. See Accessories, page 38.
INSTALLATION Continued WARNING: If pre-wiring, do not connect wiring to any electrical source at this time. Install fireplace electrical outlet and connect wiring to outlet before connecting to electrical source. The fireplace electrical outlet is included with the GA3450TA blower accessory. Only use the fireplace electrical outlet supplied with the GA3450TA blower accessory. Note: A qualified installer should make all electrical connections. 3. Install gas piping to fireplace location.
INSTALLATION Continued NOTICE: If your installation does not meet the minimum clearances shown in Figure 10, you must do one of the following: • raise the mantel to an acceptable height • remove the mantel 23" 18" 15" 21" Mantel Shelf 10" Note: 8" All vertical measurements 6" are from top of 2 1/2" fireplace opening to bottom of mantel shelf. All measurements are in inches. Side of Firebox 4. Route flexible gas line through access hole in hearth base. 5.
INSTALLATION Installing Optional Blower Accessory GA3450TA Continued 12. Lower bottom louver door. Use 3" wood screws provided with mantel accessory to attach fireplace to base (see mantel instruction sheet). Cabinet Mantel Assembled Trim Removing Upper Louver To install the blower accessory, you must first remove the upper louver. 1. Lift screen off fireplace and remove log set if installed. 2. Remove 4 screws from upper louver (see Figure 15). Save these screws. 3.
INSTALLATION Continued 5. In top of the fireplace cabinet, locate the four mounting holes on the outer casing. Align these four holes with those on the blower bracket assembly. Attach blower bracket assembly to the outer casing with 4 #10 screws provided (see Figure 16). 6. Route the wire harness through the hole in left side of baffle and between firebox wrapper and outer casing. 7.
5. Test to make sure blower is working properly. 6. Reinstall upper louver beginning with bottom screws (see Figure 15, page 13) and close lower louver. INSTALLATION Continued For Built-In Installation WARNING: A licensed electrician must connect the wiring harness to electrical supply following all local codes.

INSTALLATION Continued CONNECTING TO GAS SUPPLY WARNING: This appliance requires a 45° male flare fitting 5/8"18 UNF (Unified National Fine Thread) inlet connection and the flexible gas line provided. WARNING: A qualified service person must connect fireplace to gas supply. Follow all local codes. WARNING: Never connect natural gas fireplace to private (non-utility) gas wells. This gas is commonly known as wellhead gas.
INSTALLATION Continued H I We recommend that you install a sediment trap in supply line as shown in Figure 22, page 16. Locate sediment trap where it is within reach for cleaning. Install in piping system between fuel supply and heater. Locate sediment trap where trapped matter is not likely to freeze. A sediment trap traps moisture and contaminants. This keeps them from going into fireplace controls. If sediment trap is not installed or is installed wrong, fireplace may not run properly.
INSTALLATION Equipment Shutoff Valve Propane/LP Supply Tank Continued Pressure Testing Gas Supply Piping System Test Pressures In Excess Of 1/2 PSIG (3.5 kPa) 1. Disconnect appliance with its appliance main gas valve (control valve) and equipment shutoff valve from gas supply piping system. Pressures in excess of 1/2 psig will damage heater regulator. 2. Cap off open end of gas pipe where equipment shutoff valve was connected. 3.
INSTALLATION Continued OPTIONAL Wireless hand-held REMOTE CONTROL ACCESSORies Installing Receiver 1. Disconnect wires from the control valve (see Figure 28). 2. Locate the battery clip mounted on the back of the receiver (see Figure 29). 3. Slide 9-volt battery (not included) through the clip. 4. Attach the terminal wires to the battery (see Figure 29). 5. Connect wires from remote receiver to control valve as shown in Figure 30. 6.
INSTALLATION Terminal “W” Continued W 4. Gently remove the cover of the thermostat from the base. Grasp the sides of the cover firmly and pull to separate from the base. 5. Feed the electrical wires through the rectangular slots on each side of the base (see Figure 33). WARNING: Do not connect the thermostat to a power source. Electrical shock and/or a fire hazard will occur. 6. Connect one bare wire end to each terminal (“W” and “R”) of the thermostat base (see Figure 34). 7.
INSTALLATION Log Set Continued 3. Install left and right brick liners using brackets and screws from hardware kit as shown in Figure 36. Screw the bracket into top of firebox and against brick liners. Adjust bracket before tightening screw. 4. Remove log packaging material and discard. Gently place log over burner (see Figure 37). (Do not allow log to contact flame as this will create sooting.) 5. Insert each rod through ten rings located at top of screen (see Figure 38). 6.
