SAFETY Continued DANGER: Carbon monoxide poisoning may lead to death! Carbon Monoxide Poisoning: Early signs of carbon monoxide poisoning resemble the flu, with headaches, dizziness or nausea. If you have these signs, the fireplace may not be working properly. Get fresh air at once! Have fireplace serviced. Some people are more affected by carbon monoxide than others. These include pregnant women, people with heart or lung disease or anemia, those under the influence of alcohol and those at high altitudes.
SAFETY Continued 5. Do not use this fireplace as a wood-burning fireplace. Use only the logs provided with the fireplace. 6. Do not add extra logs or ornaments such as pine cones, vermiculite or rock wool. Using these added items can cause sooting. Do not add lava rock around base. Rock and debris could fall into the control area of fireplace. 7. This fireplace is designed to be smokeless. If logs ever appear to smoke, turn off fireplace and call a qualified service person.

AIR FOR COMBUSTION AND VENTILATION Continued DETERMINING FRESH-AIR FLOW FOR FIREPLACE LOCATION All spaces in homes fall into one of the three following ventilation classifications: 1. Unusually Tight Construction 2. Unconfined Space 3. Confined Space The information on pages 6 through 8 will help you classify your space and provide adequate ventilation. Unusually Tight Construction The air that leaks around doors and windows may provide enough fresh air for combustion and ventilation.
AIR FOR COMBUSTION AND VENTILATION Continued The space in the previous example is a confined space because the actual Btu/Hr used is more than the maximum Btu/Hr the space can support. You must provide additional fresh air. Your options are as follows: A. Rework worksheet, adding the space of an adjoining room. If the extra space provides an unconfined space, remove door to adjoining room or add ventilation grills between rooms. See Ventilation Air From Inside Building. B.
Installation NOTICE: This heater is intended for use as supplemental heat. Use this heater along with your primary heating system. Do not install this heater as your primary heat source. If you have a central heating system, you may run system’s circulating blower while using heater. This will help circulate the heat throughout the house. In the event of a power outage, you can use this heater as your primary heat source. WARNING: A qualified service person must install fireplace. Follow all local codes.
INSTALLATION Continued Fireplace Clearances WARNING: Maintain the minimum clearances shown in Figure 7. If you can, provide greater clearances from floor, ceiling and joining wall. If your fireplace is to be used with an optional mantel, the installation instructions included with your mantel shows an approved method of attaching the fireplace/mantel system to a wall. IMPORTANT: Only use optional cabinet or corner mantels specified in this manual.
INSTALLATION Continued 2. If installing GA3450TA 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 31). Use only approved three-wire electrical wiring. WARNING: If pre-wiring, do not connect wiring to any electrical source at this time.
INSTALLATION Continued WARNING: Do not allow any combustible/noncombustible materials to overlap the firebox front facing. WARNING: Do not allow combustible or noncombustible materials to cover any necessary openings like louvered slots. WARNING: Never modify or cover the louvered slots on the front of the firebox. Mantel Clearances for Built-In Installation If placing mantel above built-in fireplace, you must meet minimum clearance between mantel shelf and top of fireplace opening.
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 We recommend that you install a sediment trap in supply line as shown in Figure 14, page 13. 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 Continued CAUTION: Make sure external regulator has been installed between propane/LP supply and fireplace. See guidelines under Connecting to Gas Supply, page 13. 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.
INSTALLATION Continued Optional Wall Mounted Thermostat - GWMT1 WARNING: Read and follow installation instructions. Installation should be done by a qualified installer familiar with low-voltage wiring procedures. WARNING: Do not connect this thermostat to any electrical source! Electrical shock and/or fire hazard will occur. 1. Remove jumper wire from control valve (see Figure 20). 2. Connect one terminal of 25 ft. wire to the “TH” terminal on the control valve.
INSTALLATION Continued 8. Move temperature adjustment back and forth to insure the bimetal is free from restrictions. 9. Replace cover onto base. (Upon installation, thermostat must be allowed to stabilize at room temperature for a minimum of 30 minutes for proper operation). 10. Set temperature adjustment to desired setting. This thermostat has been electronically calibrated at the factory. No adjustment or leveling is necessary. Optional Wall SWITCH - GWMS2 INSTALLING LOG SET AND SCREEN 1.
operation FOR YOUR SAFETY READ BEFORE LIGHTING WARNING: If you do not follow these instructions exactly, a fire or explosion may result causing property damage, personal injury or loss of life. A. This appliance has a pilot which must be lighted by hand. When lighting the pilot, follow these instructions exactly. B. BEFORE LIGHTING smell all around the appliance area for gas. Be sure to smell next to the floor because some gas is heavier than air and will settle on the floor.
Operation Continued • If control knob does not pop out when released, contact a qualified service person or gas supplier for repairs. Note: If pilot goes out, repeat steps 4 through 8. 8. Slightly push in and turn control knob counterclockwise to the ON position. 9. Set flame adjustment knob to any level between HI and LO. 10. To leave pilot lit and shut off burners only, turn control knob clockwise to PILOT position. If using optional hand-held remote, use remote control manual OFF button.
Inspecting Burners Check pilot flame pattern and burner flame patterns often. PILOT FLAME PATTERN Figure 29 shows a correct pilot flame pattern. Figure 30 shows an incorrect pilot flame pattern. The incorrect pilot flame is not touching the thermocouple. This will cause the thermocouple to cool. When the thermocouple cools, the fireplace will shut down. If pilot flame pattern is incorrect, as shown in Figure 30 • turn fireplace off (see To Turn Off Gas to Appliance, page 19.
CLEANING AND MAINTENANCE Continued We also recommend that you keep the burner tube and pilot assembly clean and free of dust and dirt. To clean these parts we recommend using compressed air no greater than 30 PSI. Your local computer store, hardware store or home center may carry compressed air in a can. If using compressed air in a can, please follow the directions on the can. If you don’t follow directions on the can, you could damage the pilot assembly. 1. Shut off unit including pilot.
Troubleshooting WARNING: Turn off and unplug fireplace and let cool before servicing. Only a qualified service person should service and repair fireplace.
