AIR FOR COMBUSTION AND VENTILATION Continued If the actual Btu/Hr used is less than the maximum Btu/Hr the space can support, the space is an unconfined space. You will need no additional WARNING: If the area in which the heater may be operated is smaller than that defined as an unconfined space or if the building is of unusually tight construction, provide adequate combustion and ventilation air by one of the methods described in the National Fuel Gas Code, ANSI Z223.1/NFPA 54 Section 5.
INSTALLATION Continued Note: Your fireplace is designed to be used in zero clearance installations. Wall or framing material can be placed directly against any exterior surface of your fireplace, except where standoff spacers are integrally attached. If standoff spacers are attached to your fireplace, these spacers can be placed directly against wall or framing materials. Use the dimensions shown for rough openings to create the easiest installation (see Built-In Fireplace Installation, page 10).
INSTALLATION BUILT-IN FIREPLACE INSTALLATION Continued 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.) in the air exist, may discolor walls or cause odors. IMPORTANT: Vent-free fireplaces add moisture to the air.
INSTALLATION Continued 2. If installing GA3450T blower accessory, do so at this time. Follow instructions included with blower accessory. Note: If not installing blower accessory, you may wish to run electrical wiring to your fireplace for future blower installation (see Accessories, page 30). Use only approved three-wire electrical wiring. Note: A qualified installer should make all electrical connections. WARNING: If pre-wiring, do not connect wiring to any electrical source at this time.
INSTALLATION OPTIONAL MANTEL INSTALLATION Continued MANTEL CLEARANCES FOR BUILTIN INSTALLATION If placing mantel above built-in fireplace, you must meet minimum clearance between mantel shelf and top of fireplace opening. NOTICE: Surface temperatures of adjacent walls and mantels become hot during operation. Walls and mantels above the firebox may become hot to the touch. If installed properly, these temperatures meet the requirement of the national product standard.
INSTALLATION Continued Set Screws 13. Place mantel around fireplace. Be careful not to damage wall or mantel. 14. Place brass trim kit on the shoulder screws located on the side and top of the fireplace. Firmly snap the brass trim over the shoulder screws on fireplace (see Figure 13, page 12). 15. Adjust assembly to remove any gaps. Attach remaining two 3" wood screws from hardware pack through openings inside of fireplace sides into the mantel.
INSTALLATION Continued Removing Valve Cover Shield 1. Open bottom louver assembly by swinging the assembly down (see Figure 17). 2. Using short Phillips screwdriver, remove the screw under the center of the branch support. Rotate valve cover shield clockwise and slide out. IMPORTANT: Do not remove shoulder screw on the left side of valve cover shield. Slide the valve cover shield off of the shoulder screw (see Figure 17).
INSTALLATION Continued 9. Install the switch plate on the valve cover shield with 2 #10 screws provided (see Figure 19). Reinstall the valve cover shield. Route power cord out of the cabinet by inserting it through the bushing on the outer casing (see Figure 18, page 14). Plug fan kit into 120-Volt grounded power supply and test operation. Note: When switch is in the AUTO position, the fan will start after the heater has run for a few moments.
INSTALLATION Continued Extension Cord Use extension cord if needed. The cord must have a three-prong, grounding plug and a three-hole receptacle. Make sure cord is in good shape. It must be heavy enough to carry the current needed. An undersized cord will cause a drop in line voltage. This will result in loss of power and overheating. Use a No. 16 AWG cord for lengths less than 50 feet.
INSTALLATION Continued Installation must include an equipment shutoff valve, union and plugged 1/8" NPT tap. Locate NPT tap within reach for test gauge hook up. NPT tap must be upstream from fireplace (see Figure 24). IMPORTANT: Install an equipment shutoff valve in an accessible location. The equipment shutoff valve is for turning on and shutting off the gas to the appliance. Check your building codes for any special requirements for locating equipment shutoff valve to fireplaces.
