Set gap between ignitor electrode and nozzle to .13"/.15" (3.3/3.8 mm) c. Replace ignitor electrode. See "Maintenance: Ignitor". d. Replace spark transformer. See "Maintenance: Spark Transformer". Operator’s Manual Troubleshooting WARNING: HIGH VOLTAGE. NEVER SERVICE SPACE HEATER WHILE IT IS PLUGGED IN, OPERATING, OR HOT. SEVERE BURNS AND ELECTRICAL SHOCK CAN OCCUR. Symptom Heater shuts down while running. Heater producing odor. Problem Propane / L.P. supply may be inadequate. High surrounding air temperature causing thermal limit device to shut down heater. Restricted air flow. Damaged fan. Excessive dust or debris in surrounding area. WARNING: Use only in areas free of high dust content. Gas leak Heater operating on a 20 lb. Propane / L.P. cylinder. Insufficient Propane / L.P. gas will be supplied by a 20 lb. cylinder resulting in odor Propane / L.P. supply tank is "freezing up". Evaporation and consumption rate of propane from supply tank is to great for the size of the tank and air temperature Solution a. Refill tank b. Provide additional and/or larger tanks. See "Preparation: Propane Supply". This can happen when running heater in temperatures above 85° F (30° C). Run heater in cooler temperatures. Check heater inlet and outlet. Remove any obstructions. Replace fan. See "Maintenance: Fan". Clean heater. See "Maintenance". Check all connections for leaks. Apply mixture of liquid soap and water to gas joints. Bubbles forming show a leak that must be corrected To obtain correct mixture of Propane / L.P. gas and air, use a larger cylinder size, i.e. 40 lb. (minimum) or 100 lb. See "Preparation: Propane Supply". a. Use a larger supply cylinder size, i.e. 40 lb. (minimum) or 100 lb. b. Reduce consumption rate byoperating the heater at LOWsetting temporarily until frostdisappears from the tank Operator’s Manual Service MAINTENANCE: WARNING: TO AVOID RISK OF BURN AND ELECTRICAL SHOCK, NEVER ATTEMPT TO SERVICE SPACE HEATER WHILE IT IS PLUGGED IN, OPERATING, OR HOT. KEEP HEATER CLEAR AND FREE FROM COMBUSTIBLE MATERIALS, GASOLINE AND OTHER FLAMMABLE VAPORS AND LIQUIDS DO NOT BLOCK THE FLOW OF COMBUSTION OR VENTILATION AIR. 1. Keep heater clean. Clean heater annually or as needed to remove dust and debris. If heater is dirty or dusty, clean heater with a damp cloth. Use household cleaners on difficult spots. 2. Inspect heater before each use. Check connections for leaks. Apply mixture of liquid soap and water to connections. Bubbles forming show a leak. Correct all leaks at once. 3. Inspect hose / regulator assembly before each use. If hose is highly worn or cut, replace with hose specified by manufacturer. 4. Have heater inspected yearly by a qualified service agency. 5. Keep inside of heater free from combustible and foreign objects. Remove motor and other internal parts if needed to clean inside of heater. 6. Clean fan blades each season or as needed. Operator’s Manual Service MAINTENANCE (CONTINUED): WARNING: NEVER SERVICE HEATER WHILE IT IS PLUGGED IN, CONNECTED TO PROPANE / L.P. SUPPLY, OPERATING ORHOT. SEVERE BURNS AND ELECTRICAL SHOCK CAN OCCUR. MOTOR: 1. With heater on its side, remove base tray. 2. Access ground screw through underside of heater base. Remove ground screw. Disconnect the green motor wire and the green power cord wire from underside of shell (Fig. 3). 3. Remove black and white motor wires from terminal board (Fig. 3). 4. Carefully push motor wires through hole in bottom of shell. 5. Remove screws holding motor mount to shell. Use nut- driver (Fig. 4). 6. Carefully pull motor and fan out of shell. IMPORTANT: Be careful not to damage fan. Do not set motor and fan down with the weight resting on fan. This could damage fan pitch. 7. Use hex wrench to loosen setscrew which holds fan to motor shaft. 8. Remove fan. Be careful not to damage the fan blade pitch. 9. Use nut driver to remove two nuts that attach motor to motor mount. 10. Discard old motor. 11. Attach motor to motor mount with two nuts. Tighten nuts firmly. 12. Replace fan on motor shaft. Make sure set screw contacts flat surface on motor shaft. 13. Tighten set screw firmly (40-50 inch-pounds [46.08- 57.60 kilogram-centimeters]). 14. Carefully route motor wires through hole in shell (Fig. 5). Place motor, motor mount and fan guard into rear of heater shell. 15. Insert screws through heater shell and into motor mount. Tighten screws firmly. 16. Turn heater on its side to access opening in bottom of base. Connect green wires from motor, transformer and power cord to heater shell using ground nut (Fig. 3). 17. Attach black and white wires to terminal board (see "Wiring Diagram" for correct locations). 18. Replace base tray.
