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. WHAT TO DO IF YOU SMELL GAS • Do not try to light any appliance. • Do not touch any electric switch; do not use any phone in your building. • Immediately call your gas supplier from a neighbor’s phone.
Operating Fireplace 10. Wait one minute and switch selector switch to the ON position to light burner. 11. Set flame adjustment knob to any level between HI and LO. CAUTION: Do not try to adjust heating levels by using the equipment shutoff valve. WARNING: Make sure the selector switch is in the OFF position when you are away from home for long periods of time. Heater will come on automatically with selector switch in the ON position.
