If the gas control is turned to the “OFF” position or gas flow to the appliance is shut off, the pilot cannot be relighted until the safety magnet is deenergized (approximately 60 seconds). There will be an audible “click” when the safety magnet in the gas control is de-energized. Pilot can now be relighted. Repeat steps 5 through 9. 11. Turn gas control knob counterclockwise to “ON”. 12. Turn on all electric power to the appliance. (If applicable) 13. Replace access panel (front panel). Set thermostat to desired setting. 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. LIGHTING INSTRUCTIONS PILOT FLAME CHARACTERISTICS PILOT FLAME CHARACTERISTICS The correct flame will be almost horizontal, blue and will extend past the thermocouple 1/4" (6mm). The flame will surround the thermocouple just below the tip. On Propane (LP-gas) slight yellow might occur where the pilot flame and the burner flame meet. Natural gas pilots require adjusting when the inlet pressure is above 5" w.c. (1.25kPa). Remove pilot adjustment cover. Turn adjustment screw clockwise to reduce flame. Propane (LP-gas) will not require adjusting. 3/16" (5mm) Figure 5 MAIN BURNER FLAME CHARACTERISTICS There will be a short blue inner flame with a larger, lighter blue secondary flame. The burner flame may have yellow tips when hot. Dust in the combustion air will produce an orange or red flame. Do not mistake the orange or red flame for an improper yellow flame. The flame will be proper if the factory-set pressure and orifice are used. After use, cleaning may be required for the proper flame. On Propane gas, if a whistling noise (resonation) occurs a. Screw the air adjustment bolt into the burner throat to eliminate the whistling noise (resonation). b. Size main burner orifice with a drill bit. For RH-50(C) use #47 drill bit. For RH-65(C) use 2.3mm drill bit. Primary Air Adjustment see page 11. Figure 6 Page 10 12822-2-0903 MAINTENANCE MAINTENANCE Cleaning Pilot Burner After use, cleaning of the pilot burner may be required for the proper flame. The pilot orifice can be cleaned with high pressure air or by placing under running water. Pilot orifice must be dry before replacement. Use a pipe cleaner to clean inside the pilot after the pilot orifice has been removed. Removing Pilot Orifice 1. Disconnect the pilot supply line at the pilot burner. 2. Remove pilot orifice from pilot burner. It may be necessary to tap on pilot burner in order to remove the pilot orifice. Cleaning Main Burner Remove the burner and apply water pressure inside the throat of the burner and down into the ports; follow with air pressure. Removing Main Burner 1. Remove casing front. 2. Disconnect pilot bracket from the burner. 3. Remove brass nut from burner. 4. Disconnect burner from chamber leg flange. 5. Remove burner from bottom of combustion chamber. Cleaning Combustion Chamber A qualified serviceman should remove the chamber and apply air pressure to the inside in order to clear all passageways. Primary Air Adjustment 1. A primary air adjustment bolt is located on left, front of burner throat. The bolt can be screwed into burner throat to REDUCE primary air or unscrewed from burner throat to INCREASE primary air. To reduce yellow flame on main burner unscrew bolt from burner throat. Also, refer to Step 2. To reduce resonation (whistling) noise or extinction (popping) noise screw bolt into burner throat. 2. An air shutter bracket is attached to top of burner throat. The air shutter bracket lays flat across top of burner throat. If yellow flames can not be removed from main burner by using primary air adjustment bolt, the air shutter bracket can be pivoted upward to allow additional primary air to enter burner throat. On Propane gas, if a whistling noise (resonation) occurs screw the air adjustment bolt into the burner throat to eliminate the whistling noise (resonation). TROUBLESHOOTING 1. Impossible to light pilot a. If using piezo ignitor, check electrode location. b. Remove nut at orifice and check for gas. c. If gas available, check for blocked orifice or pilot. 2. Pilot outage a. Proper size of pilot flame. b. Defective or weak thermocouple. 3. Pilot flames but goes out a. Pilot flame not covering the thermocouple properly when knob is released. b. Defective thermocouple. c. Defective magnet in the safety section of valve. 4. Poor thermostatic control a. Thermostat needs calibrating. b. Defective thermostat section. 5. Noisy blower a. Tighten blower screws. b. Check blower wheel in the open for balance. 6. Yellow main burner flame a. Remove main burner to check for obstructions in throat, ports and orifices. b. Install new main burner orifice and pilot orifice. c. Check gas valve for leaking. d. Open the air bolt on the main burner in order to increase the amount of primary air. 7. Yellow pilot flame a. Small yellow tip not objectiona...
