OPERATING HEATER 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.
OPERATING HEATER 4. Wait five (5) minutes to clear out any gas. Then smell for gas, including near the floor. If you smell gas, STOP! Follow “B” in the safety information at the top of page 16. If you don’t smell gas, go to the next step. Continued 5. Turn control knob counterclockwise to the PILOT position. Press in control knob for five (5) seconds (see Figure 16, page 16). Note: You may be running this heater for the first time after hooking up to gas supply.
OPERATING HEATER Continued TO TURN OFF GAS TO APPLIANCE Shutting Off Heater 1. Turn control knob clockwise to the OFF position. 2. Turn off all electric power to the appliance if service is to be performed. Shutting Off Burner Only (pilot stays lit) to the PILOT position. 1. Turn control knob clockwise THERMOSTAT CONTROL OPERATION The thermostatic control used on these models differs from standard thermostats. Standard thermostats simply turn on and off the burner.
INSPECTING BURNER Check pilot flame pattern and burner flame pattern often. PILOT FLAME PATTERN Figure 18 shows a correct pilot flame pattern. Figure 19 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 heater will shut down.
INSPECTING BURNER Continued BURNER FLAME PATTERN Figure 20 shows a correct burner flame pattern. Figure 21 shows an incorrect burner flame pattern. The incorrect burner flame pattern shows yellow tipping of the flame. It also shows the flame higher than 1/2 the glass panel height. WARNING If yellow tipping occurs, your heater could produce increased levels of carbon monoxide. If burner flame pattern shows yellow tipping, follow instructions at bottom of this page.
CLEANING AND MAINTENANCE WARNING Turn off heater and let cool before cleaning. CAUTION You must keep control areas, burner, and circulating air passageways of heater clean. Inspect these areas of heater before each use. Have heater inspected yearly by a qualified service person.
