D. Do not use this appliance if any part has been underwater. Immediately call a qualified service technician to inspect the appliance and to replace any part of the control system which has been underwater. LIGHTING INSTRUCTIONS 1. STOP! Read the all safety information included with and on the side of heater. 2. Make sure the equipment shutoff valve is fully open. 3. Push in gas control knob and slightly turn clockwise to the OFF position (see figure 19). 4. Wait five (5) minutes. Then smell for gas including near the floor. If you smell gas, STOP! Follow “B” in the safety information above. If you do not smell gas, go to the next step. 5. Push in and turn control knob counterclockwise to PILOT/IGN. Press in control knob for five (5) seconds. Note: The first time that the heater is operated after connecting the gas supply, the control knob should be depressed for about 30 seconds. This will allow air to bleed from the gas system. Control Knob Ignitor Button Figure 19. 6. With control knob pressed in, push down and release the ignition button. This will light pilot. If needed keep pressing igniter button until pilot lights. 7. Keep control knob pressed in for (30) seconds after lighting pilot. After 30 seconds, release control knob. Figure 20 • If pilot does not stay lit, refer to Troubleshooting, pages 14 & 15. Also, contact a qualified service person of gas supplier for repairs. • If control knob does not pop up when released, contact a qualified service person or gas supplier for repairs. 11 Installation instructions and Owner’s Manual 8. When the pilot is lit, turn control know counterclockwise to heating level. The main burner should light. 9. To select the desired heat level, turn the temperature setting knob counterclockwise to between 1 & 7. THERMOSTAT CONTROL OPERATION FOR IR20NGT / IR30NGT: The thermostatic control used simply turns on and off the burner. FOR BF20NGT / BF30NGT: The thermostatic control used modulates the flame size as the temperature gets closer to set point, then it turns off the burner upon reaching temperature. 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 1 and 7. Selecting the HI setting will cause the burner to remain on. Note: The thermostat sensing bulb measures the temperature of air near the heater cabinet. This may not always agree with room temperature (depending on housing construction, insulation location, room size, open air temperature, etc.). Frequent use of your heater will let you determine your own comfort levels. TO TURN OFF GAS TO APPLIANCE SHUTTING OFF HEATER 1. Turn control knob clockwise to the OFF position. 2. Turn off all electrical power to the appliance if servicing is to be preformed. 3. Turn off equipment shutoff valve. SHUTTING OFF BURNER ONLY (PILOT STAYS LIT) 1. Turn control knob clockwise to the PILOT/IGN position. INSPECTING BURNER Check pilot flame pattern and burner flame pattern often. PILOT FLAME PATTERN Figure 21 show a correct pilot flame pattern. Figure 22 shows an incorrect pilot flame pattern. The incorrect pilot flame pattern is not touching thermocouple. This will cause the thermocouple to cool. When the thermocouple cools, the heater will shut down. If pilot flame pattern is incorrect, as shown in Figure 22: • Turn heater off (see To Turn OFF Gas to Appliance, page 11 for non-thermostat models or page 12 for thermostat models). • See Troubleshooting, pages 14 and 15. Figure 21 Figure 22 BURNER FLAME PATTERN Figure 23 show a correct burner flame pattern. Figure 24 shows an incorrect burner flame pattern. If burner flame pattern is incorrect, as shown in Figure 24: • Turn heater off (see To Turn OFF Gas to Appliance, page 11 for non-thermostat models or page 12 for thermostat models). • See Troubleshooting, pages 14 and 15. Figure 23a. Figure 23b. Figure 24a. 12 Installation instructions and Owner’s Manual 70574 REV. C 8/05 Figure 25 CLEANING AND MAINTENANCE WARNING: Turn off heater and let cool before servicing. CAUTION: You must keep control areas, burner and circulation air passageways of heater clean. Inspect these areas of heater before use. Have the heater inspected yearly by a qualified service person. Heater may need more frequent cleaning due to excess lent from carpeting, bedding material, pet hair, etc. Make sure grille guard is in place before running heater. If screen or grille guard is removed for servicing it must be replaced prior to operating the heater. WARNING: Failure to keep the primary air opening(s) of the burner(s) clean may result in sooting and property damage. CLEANING HEATER CABINET Air passageways • Use a vacuum cleaner or pressurized air to clean Exterior • Use a soft cloth dampened with a mild soap and water mixture. Wipe the cabinet to remove dust. CLEANING ODS/PILOT AND BURNER • Use as vacuum cleaner, pressurized air or small soft bristled brush to clean. CLEANING BURNER PILOT AIR HOLE INLET We recommend that yo...
