• You must operate this heater with a fireplace screen in place. Make sure fireplace screen is closed before running heater. NOTICE During initial operation of new heater, burning logs will give off a paper- burning smell. Orange flame will also be present. Open damper or window to vent smell. This will only last a few hours. Note:Homeowners generally prefer to operate their heater with the chimney damper closed. This will put all the heat into the room. However there may be times you will desire the full flames of the Hi heat setting but will find the heat output excessive. You can open the chimney damper (if you have one) fully or partially to release some of the heat. WARNING: Damper handle will be hot if heater has been running. 1. STOP! Read the safety information above. 2. Make sure manual shutoff valve is fully open. 3. Turn control knob clockwise to the OFF position. Ignitor Button Control Knob PILOT OFF LO HI Figure 20 - Control Knob and Ignitor Button Location 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 above. If you don’t smell gas, go to the next step. 20 OPERATING HEATER Continued 5. Turn control knob counterclockwise to the PILOT position. Press in control knob for five (5) seconds (see Page 20). Note:You may be running this heater for the first time after hooking up to gas supply. If so, the control knob may need to be pressed in for 30 seconds or less. This will allow air to bleed from the gas system. • If control knob does not pop out when released, contact a qualified service person or gas supplier for repairs. 6. With control knob pressed in, press and release ignitor button. This will light pilot. The pilot is attached to the front burner. If needed, keep pressing ignitor button until pilot lights. Note:If pilot does not stay lit, contact a qualified service person or gas supplier for repairs. Until repairs are made, light pilot with match. To light pilot with match, see Manual Lighting Procedure, below. 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 heater has a safety interlock system. Wait one (1) minute for system to reset before lighting pilot again. Thermocouple Ignitor Electrode Pilot Burner Figure 21 - Pilot 8. Turn control knob counterclockwise to desired heating level. The burners should light. Set control knob to any heat level between HI and LO. CAUTION Do not try to adjust heating levels by using the manual shutoff valve. TO TURN OFF GAS TO APPLIANCE Shutting Off Heater 1. Turn control knob clockwise to the OFF position. Shutting Off Burners Only (pilot stays lit) 1. Turn control knob clockwise to the PILOT position. THERMOSTAT CONTROL OPERATION (Thermostat-Controlled Models Only) The thermostat control knob can be set to any comfort level between Hi and Lo. The thermostat will gradually modulate the heat output and flame height from higher to lower settings, or pilot, in order to maintain the comfort level you select. The ideal comfort setting will vary by household depending upon the amount of space to be heated, the output of the central heating system, etc. Note:Selecting the Hi setting with the control knob will cause the burner to remain fully on, without modulating down in most cases. VARIABLE CONTROL OPERATION The variable control valve can be set to any heat setting and flame height desired, by simply turning the control knob until that setting is attained. Even the lowest setting provides realistic flames and glowing embers from two burners. Selecting higher settings produces greater heat output. This results in increased heating comfort. INSPECTING BURNERS Check pilot flame pattern and burner flame patterns often. PILOT FLAME PATTERN Figure 22 shows a correct pilot flame pattern. Figure 23 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. Thermocouple Pilot Burner Figure 22 - Correct Pilot Flame Pattern If pilot flame pattern is incorrect, as shown in Figure 23 • turn heater off (see To Turn Off Gas to Appliance, page 21) • see Troubleshooting, pages 23 through 26 FRONT BURNER FLAME PATTERN Figure 24 shows correct front burner flame pattern. Figure 25 shows incorrect front burner flame pattern. The incorrect burner flame pattern shows yellow tipping at top of blue flame. Pilot BurnerThermocouple Figure 23 - Incorrect PilotFlame Pattern WARNING If yellow tipping occurs, your heater could produce increased levels of carbon monoxide. If front burner flame pattern shows yellow tipping, follow instructions at bottom of this page. Yellow flame on rear burner is normal. NOTICE Do not mistake orange flames with yellow tipping. Dirt or other fine particles are burned by heater, causing brief patches of or...
