7. Keep control knob pressed in for 30 seconds after lighting pilot. After 30 seconds, release control knob. Note: If pilot goes out, repeat steps 3 through 7. This fireplace has a safety interlock system. Wait one (1) minute before lighting pilot again. 8. Turn control knob counterclockwise to desired heating level. The main burner should light. Set control knob to any heat level between HI and LO. CAUTION: Do not try to adjust heating levels by using the equipment shutoff valve.

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) Turn control knob clockwise to the PILOT position. THERMOSTAT CONTROL OPERATION The thermostatic control used on this fireplace differs from standard thermostats. Standard thermostats simply turn on and off the burner. The thermostat used on this fireplace senses the room temperature. The thermostat adjusts the amount of gas flow to the burner. This increases or decreases the burner flame height. At times the room may exceed the set temperature. If so, the burner will shut off. The burner will cycle back on when room temperature drops below the set temperature. The control knob can be set to any heat level between HI and LO. Note: The thermostat sensing bulb measures the temperature of air near the fireplace cabinet. This may not always agree with room temperature (depending on housing construction, installation location, room size, open air temperatures, etc.). Frequent use of your fireplace will let you determine your own comfort levels. MANUAL LIGHTING PROCEDURE 1. Follow steps 1 through 5 under Lighting Instructions, starting on page 19, column 1. 2. With control knob pressed in, strike match. Hold match to pilot until pilot lights. 3. Keep control knob pressed in for 30 seconds after lighting pilot. After 30 seconds, release control knob. Now follow step 8 under Lighting Instructions, column 1 113111-01A OPERATING FIREPLACE Continued OPERATING BLOWER This blower has three settings: ON, OFF, and AUTO. In the ON position, the blower will operate constantly. In the OFF position, the blower will not operate. In the AUTO position, the blower will start when the thermostat senses a sufficient increase in firebox temperature. Note: Your fireplace and thermostat blower will not turn on and off at the same time. The fireplace may run for several minutes before the blower turns on. After the heater modulates to the pilot position, the blower will continue to run. The blower will shut off after the firebox temperature decreases. Note: It is safe to operate fireplace with blower turned off. However, the blower helps distribute heated air from the fireplace. Auto/Off/On Switch Figure 31 - Auto/Off/On Switch INSPECTING BURNER Check pilot flame pattern and burner flame pattern often. PILOT FLAME PATTERN Figure 32 shows a correct pilot flame pattern. Figure 33 shows an incorrect pilot flame pattern. The incorrect pilot flame is not properly heating 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 33 • turn fireplace off (see To Turn Off Gas to Appliance, page 20) • see Troubleshooting, pages 23 through 26 Note: The pilot flame on natural gas units will have a slight curve, but flame should be blue and have no yellow or orange color. Pilot Burner Thermocouple Figure 32 - Correct Pilot Flame Pattern (Propane/LP Shown) Thermocouple Pilot Burner Figure 33 - Incorrect Pilot Flame Pattern (Propane/LP Shown) BURNER FLAME PATTERN Figure 34 shows a correct burner flame pattern. Figure 35 shows an incorrect burner flame pattern. The incorrect burner flame pattern shows sporadic, irregular flame tipping. The flame should not be dark or have an orange/reddish tinge. Note: When using the fireplace the first time, the flame will be orange for approximately one hour until the log cures. If burner flame pattern is incorrect, as shown in Figure 35 • turn fireplace off (see To Turn Off Gas to Appliance, page 20) • see Troubleshooting, pages 23 through 26 Figure 34 - Correct Burner Flame Pattern Figure 35 - Incorrect Burner FlamePattern 113111-01A CLEANING AND MAINTENANCE WARNING: Failure to keep the primary air opening(s) of the burner(s) clean may result in sooting and property damage. WARNING: Turn off fireplace and let cool before cleaning. CAUTION: You must keep control areas, burner, and circulating air passageways of fireplace clean. Inspect these areas of fireplace before each use. Have fireplace inspected yearly by a qualified service person. Fireplace may need more frequent cleaning due to excessive lint from carpeting, be...
