UNPACKING ASSEMBLY 1. Remove all packing items applied to heater for shipment. 2. Remove all items from carton. 3. Check items for any shipping damage. If heater is damaged, promptly inform dealer where you bought heater. These models are furnished with wheels and handles. Wheels, handles, and the mounting hardware are found in the shipping carton. Tools Needed • Medium Phillips Screwdriver • 3/8" Open or Adjustable Wrench • Hammer 1. Slide axle through wheel support frame. Install wheels on axle.
THEORY OF OPERATION The Fuel System: The air pump forces air through the air line. The air is then pushed through the burner head nozzle. This air causes fuel to lift from the tank. A fine mist of fuel is sprayed into the combustion chamber. The Air System: The motor turns the fan. The fan pushes air into and around the combustion chamber. This air is heated and provides a stream of clean, hot air. The Ignition System: The electronic ignitor sends voltage to the spark plug.
VENTILATION WARNING Follow the minimum fresh, outside air ventilation requirements. If proper fresh, outside air ventilation is not provided, carbon monoxide poisoning can occur. Provide proper fresh, outside air ventilation before running heater. Provide a fresh air opening of at least three square feet (2800 square cm) for each 100,000 Btu/Hr rating. Provide extra fresh air if more heaters are being used.
OPERATION Continued To Stop Heater 1. Turn ON/OFF switch to “OFF.” 2. Unplug power cord from outlet. To Restart Heater 1. Wait 2 minutes after stopping heater. 2. Repeat steps under To Start Heater, page 7. STORING, TRANSPORTING, OR SHIPPING Note: If shipping, transport companies require fuel tanks to be empty. 1. Drain fuel tank by removing drain plug on underside of fuel tank. 2. Replace drain plug. 3.
TROUBLESHOOTING WARNING Never service heater while it is plugged in, operating, or hot. Severe burns and electrical shock can occur. OBSERVED FAULT POSSIBLE CAUSE REMEDY Heater ignites, but flame-out control shuts off heater after a short period of time Wrong pump pressure Dirt in nozzle See Pump Pressure Adjustment, page 12. See Air Output, Air Intake and Lint Filters, page 12. See Fuel Filter, pages 10 and 11. See Nozzle, page 13. Dirty photocell lens Bad flame-out control Clean photocell lens.
SERVICE PROCEDURES WARNING Never service heater while it is plugged in, operating, or hot. Severe burns and electrical shock can occur. Upper Shell Upper Shell Removal 1. Remove screws along each side of heater using 5/16" nut-driver. These screws attach upper and lower shells together. 2. Lift upper shell off. 3. Remove fan guard. Figure 7 - Upper Shell Removal (REMJ70) Upper Shell Fan Guard Figure 8 - Upper Shell Removal (REMJ150) Fuel Filter (REMJ70) 1.
Fuel Filter Fuel Filter, Bushing, and Lower Fuel Line (REMJ150) 1. Remove side cover screws using 5/16" nut-driver. 2. Remove side cover. 3. Pull upper fuel line off fuel filter neck. 4. Carefully pry bushing, lower fuel line, and fuel filter out of fuel tank. 5. Wash fuel filter with clean fuel and replace in tank. 6. Attach upper fuel line to fuel filter neck. 7. Replace side cover. Upper Fuel Line Side Cover Figure 10 - Fuel Filter Removal (REMJ150) Spark Plug 1. Remove upper shell (see page 10).
Air Intake Filter Air Output, Air Intake, and Lint Filters Filter End Cover 1. Remove upper shell (see page 10). 2. Remove filter end cover screws using 5/16" nutdriver. 3. Remove filter end cover. 4. Replace air output and lint filters. 5. Wash or replace air intake filter (see Preventative Maintenance Schedule, page 8). 6. Replace filter end cover. 7. Replace fan guard and upper shell.
Nozzle 1. Remove upper shell (see page 10). 2. Remove fan (see page 15). 3. Remove fuel and air line hoses from burner head. 4. Remove spark plug wire from spark plug. 5. Remove spark plug from burner head using 13/16" open-end wrench. 6. Remove three screws using 5/16" nut-driver and remove burner head from combustion chamber. 7. Place burner head into vise and lightly tighten. 8. Carefully remove nozzle from burner head using 5/8" socket wrench (see Figure 18). 9.
Blade Pump Rotor (Procedure if rotor is binding) 1. Remove upper shell (see page 10). 2. Remove filter end cover screws using 5/16" nutdriver. 3. Remove filter end cover and air filters. 4. Remove pump plate screws using 5/16" nutdriver. 5. Remove pump plate. 6. Remove rotor, insert, and blades. 7. Check for debris in pump. If debris is found, blow out with compressed air. 8. Install insert and rotor. 9. Check gap on rotor. Adjust to .003"/.004" (.076/.101 mm) if needed (see Figure 21).
Fan IMPORTANT: Remove fan from motor shaft before removing motor from heater. The weight of the motor resting on the fan could damage the fan pitch. Setscrew Fan 1. Remove upper shell (see page 10). 2. Use 1/8" allen wrench to loosen setscrew which holds fan to motor shaft. 3. Slip fan off motor shaft. 4.
