  • Page 6: Safety Precautions

    Safety Precautions These precautions are in addition to those stated in the owner’s manual by the manufacturer of the heater. Ventilation Always provide adequate ventilation to ensure a sufficient supply of fresh air. Allow at least 3 square feet of opening per 100,000 btu of heater output. For example: a 50,000 btu heater would require at least 1-1/2 square feet of open- ing to supply enough fresh air for safe operation.

  • Page 7: Definitions Of Oil Fired Heater Types

    Defining Oil Fired Heaters This book is about oil fired torpedo heaters. Low Pressure Low pressure heaters operate with an air pump which consists of a rotor and vanes. Operating pressure rarely goes above 9.0 PSI. High Pressure High pressure oil heaters use a mechanical gear type fuel pump driven by the motor to reach a high level of pressure.

  • Page 14: Tools Required

    Preparation/Tools Required Low Pressure Oil Heaters have many small parts: Start by making a clean work area. This will give you an area to layout the disassembled parts. Gather the tools required before work is started. You will need the following: 1/4" and 5/16"...
  • Page 15 The ignition system consists of a transformer or electronic igniter and a spark plug. The transformer increases the input voltage to a much greater potential, which causes an arc to jump between the electrodes of the spark plug. This arc will ignite the fuel and air mixture with in the combustion chamber.
  • Page 16 How It Works If you understand how this heater operates, you will be able to service and maintain it. The principle is simple. No oil pump is needed. The oil is sup- plied by a siphon system. Air pressure is used for the siphon., therefore it is important to maintain proper air pressure adjustment.

  • Page 17: Component Description And Operation

    Component Description and Operation 12 o'clock Fig. 1 (E) Mount screw (Pump body ring) (A) Back of Motor (B) Pump Body Ring (G) .003 to .005 Gap (C) Rotor (F) Rotor Insert (D) Blade or Vane (H) Large Gap 6 o'clock Air Pump The heater's air pump consists of a rotor (c) with four carbon blades (d) rotating inside a pump body(b).
  • Page 18 FIG. 3 Nozzle As mentioned previously, the purpose of the air pump is to compress air and deliver it to the nozzle. The compressed air, as it travels through the nozzle, creates a negative pressure and lifts the fuel from the fuel tank. The fuel from the fuel tank and the compressed air are mixed at the nozzle which results in a very fine mist of fuel being sprayed into the combustion chamber.
  • Page 19 Motors FIG. 5.1 FIG. 5.2 The motors used on the low pressure heaters are fractional horsepower motors ranging from 1/35 HP on the smallest heaters to 1/4 HP on the largest heaters. The motors used can be grouped into two categories.
  • Page 20 Solid State Relay (Applicable models use 097061-01 Solid State Relay) The solid state relay is used to de-energize the start winding on split-phase motors. As mentioned in the Motor Section, remember that split-phase motors have both an auxiliary (start) and a main (run) winding.
  • Page 21 Hot Surface Ignition Heaters (HSI) On hot surface ignition (HSI) heaters the ignition control board (ICB) is what controls the entire heater electronically. There is no reset button and no motor start relay, with exception to some older HSI models. The ICB takes care of those components internally.
  • Page 22 Glowbar (cont.) Installation 1. Unplug the heater from the 120 volt source. 2. Remove the two wires for the existing glowbar from the pc board mounted inside the access panel. 3. Disconnect the air line and fuel line from the fittings on the nozzle adapter or burner head.
  • Page 23 Electric Igniter (Transformer) (Applicable models use 079870-01 or 102482-01 Electronic Igniter) The electronic igniter operates on 120V60 Hz. It delivers approximately 15,000 volts average to the spark plug causing the kerosene sprayed from the nozzle assembly to ignite. The igniter operates on a pulse basis. The igniter has no internal service parts and must be replaced when found defective.
  • Page 24 Toro Spark Plug The spark plug must be positioned all the way in against the housing; line up the red line of the spark plug with the casting line on the burner. Gap the spark plug to .062"(FIG. 9). If plug is fouled, clean or replace. Test spark plug by removing top cover, remove air gauge plug, loosen setscrew and remove spark plug from the burner.
  • Page 25 MAINTENANCE PROCEDURES Air Compressor Servicing The air compressor is built to very close tolerances and is susceptible to exces- sive moisture accumulation. Handle all parts with care and keep them clean and dry. Dirt, oil, water and other foreign material will interfere with proper operation of the compressor.
  • Page 26 F. Using a new air-filter housing gasket between housing halves and new/clean output filter, install outer housing to inner housing and secure with the five (5) remaining. Be certain gasket is properly installed around the perimeter and in center section. Air leakage from the HIGH PRESSURE (left) side will result in lower air pressure readings.
  • Page 27 No or low air pressure may be caused by a missing "O" ring check that O-Ring is in place. FIG. 14 *Two (2) styles of Back Plates and Inner Housing Halves were used at time of pro- duction. Determine which style the heater involved contains to insure proper Assembly and Operation.
  • Page 28 Toro Fuel Tube Dimensions* Upper Fuel Lower fuel tube must be a Tube replacement item ordered from PHP, as its length will affect pick Fuel Filter up tube length. Excessive length will cause the tube to kink and block fuel flow.
  • Page 29 Nozzle Servicing Accumulation of dirt from fuel and carbon from the compressor vanes will eventually fill up the passages in the nozzle, resulting in reduction of fuel and air flow. Pressure will gradually increase giving improper fuel-air mixture causing excess odor and smoke. To clean the nozzle, usually compressed air is sufficient.Caution: Safety glass- es should be worn.
  • Page 30 Toro Nozzle Adjustment Nozzle adjustments may be necessary to alter the spray pattern-to-spark-plug relationship, due to changes in climate, oil, altitude, or after cleaning. If the heater operates properly there is no reason to change the factory setting. However, if the unit starts sluggishly in cold weather, make the following adjustments.
  • Page 31 Transformer Test Three styles of transformers have been used in the Low Pressure Heaters. Prior to 1986 an enclosed style was used and mounted as shown in FIG. 21. Since 1986 an open style transformer has been used it is shown FIG. 22 and mounts through the same two mounting bracket holes as the enclosed style transformer.

  • Page 119: Theory Of Operation

    High Pressure Theory of Operation When the thermostat is turned up power is sent to the flame/safety control and to the fan switch. This brings power to the motor relay and the trans- former. The transformer raises the voltage to a high level and sends the high voltage to a spark plug or electrode(s).

  • Page 120: Component Description And Operation

    Component Description and Operation Fuel Pump The fuel pump draws fuel from the fuel tank and pressurizes it to a high level. Pump pressures vary by manufacturer and model, but typically fall into a range of 80 to 160 pounds per square inch, or PSI. The pump is driven by the heater motor.
  • Page 121 solenoid valve, transformer and motor. If flame is not detected within approx- imately 45 seconds, power is removed from the solenoid valve and the trans- former. Depending on the temperature of the fan switch, the heater will then run a cool down phase or totally shut down. Photocell The photocell contains a light sensitive cell and is aimed thru an opening in the combustion chamber to detect the presence of flame.
  • Page 122 Spark plug or electrode(s) The high voltage sent by the transformer is received by the spark plug or elec- trode(s) and jumps across the gap to ignite the fuel spray. Consult the owner’s manual of your heater for the recommended gap or position. Thermostat The setting of the thermostat decides whether power is sent to the safety/flame control.

  • Page 123: Troubleshooting

    High Pressure Troubleshooting To use the troubleshooting section, look up the symptom you observe for the possible causes. This section is based on the Master brand models B350 and B600 manufactured by Desa. Other brands and models may differ somewhat, but the troubleshooting and tests are applicable in most cases.
  • Page 124 2. Fuel pump seized. Unplug the heater and remove the top shell to access the fan blade. Standing behind the heater, attempt to turn the fan blade clockwise by hand. If the fan blade is difficult to turn, rock the fan blade back and forth (clockwise and counterclockwise) to loosen the pump.
  • Page 125 6. Dirty or worn nozzle. 7. Drawing air in on fuel inlet line of pump. 8. Defective fuel pump. Solutions: 1. Defective transformer. If no spark is observed at the spark plug or electrode(s) check that the hot and neutral wires to the transformer are properly connected. Check to make sure the transformer output wire is connected to the spark plug or electrode(s).
  • Page 126 5. Dirty fuel filter. Inspect the fuel filter and clean or replace as needed. If your heater has a can- ister type filter remember to fill the canister with fuel before re-attaching the filter. This will help prime the fuel pump. 6.
  • Page 127 a cleaner be necessary, use an alcohol based cleaner that will dry completely without leaving an oil residue. If the photocell is clean and this symptom continues, remove the photocell for testing. Place a flashlight or lamp shining directly at the photocell eye. Set a multimeter to read ohms and connect the two multimeter probes to the two photocell wires.
  • Page 128 Heater ignites, but combustion is poor or uneven. Causes: 1. Incorrect pump pressure. 2. Dirty or worn nozzle. 3. Dirty fuel filter. 4. Spark plug or electrode(s) not gapped or positioned properly. 5. Weak spark output from transformer. 6. Fuel contaminated by water or impurities. Solutions: 1.
  • Page 129 Solutions: 1. Flame/safety control reset button is tripped. Check to see if the flame/safety control reset button is tripped. If your heater is equipped with a thermostat, turn the thermostat up to its highest setting and press the reset button. If pressing the reset button does not power up the heater, either the thermostat or flame/safety control is defective.
  • Page 130 Solutions: 1. Pump pressure too high. Use a high pressure fuel gauge attached to the pump’s gauge port to check the pump pressure. Use the pump’s pressure adjustment if the pressure is higher than the manufacturer’s recommended setting. 2. Incorrect fuel. Only use fuels recommended by the specific manufacturer of the heater.

    Indirect Oil Troubleshooting Symptoms: Motor and transformer do not operate. Page 146. Motor does not start, but spark is present. Page 147. Motor runs, spark is present, but there is no fuel spray. Page 148. Motor runs, fuel sprays, but no spark is observed. Page 150. Motor runs, fuel sprays, spark is present, but heater will not ignite.
  • Page 147 3. Thermostat is defective or not turned up to call for heat. Turn the thermo- stat up to the highest possible setting and try to start the heater. Next set a multi-meter to measure voltage coming out of the thermostat. If approximate- ly 120 volts is not measured, the thermostat is defective.
  • Page 148 4. Fuel pump seized. With the heater unplugged, stand behind the heater and attempt to turn the fan blade clockwise by hand. If the fan blade is difficult to turn, undo the connection between the motor shaft and the pump shaft. Attempt turning the fan blade again.
  • Page 149 3. Solenoid valve is defective. Use a multi-meter set to measure volts. Check for approximately 120 volts at the ends of the two wires that carry voltage to the solenoid valve. If proper voltage is read, try cleaning the valve if it is dirty. If the valve will not open fully to allow fuel spray, the solenoid valve is defec- tive.
  • Page 150 Motor runs, fuel sprays, but no spark is observed Causes: 1. Electrodes damaged or gapped incorrectly. 2. Transformer defective. 3. Control board defective. Solutions: 1. Electrodes damaged or gapped incorrectly. Inspect the electrode tips for melting. Make sure there are no cracks in the porcelain insulation. Check the electrodes with the manufacturer’s specifications for gapping and spacing.
  • Page 151 the pump pressure to the manufacturer’s specifications. 2. Electrodes damaged or gapped incorrectly. Inspect the electrode tips for melting. Make sure there are no cracks in the porcelain insulation. Check the electrodes with the manufacturers specifications for gapping and spacing. Adjust or replace the electrodes as needed.
  • Page 152 the photocell or borrow a known functioning photocell from an identical heater. 2. Control board is defective. If the heater’s spray and spark are correct, the photocell and control board must work together to recognize the combustion flame has become established. Therefore if a new photocell does not correct this symptom, the control board is defective.
  • Page 153 and the overheat thermostat is still hot. Place the multi-meter probes on the two male terminals of the safety thermostat. If the multi-meter reads infinity (no continuity) the safety thermostat is defective. Remember that if the heater is over firing due to high pump pressure, worn nozzle, or is improperly duct- ed or vented, the safety thermostat will heat enough to shut the heater off.
  • Page 154 6. Whirl disk dirty or mis-aligned. 7. Ducting is improper. 8. Venting is improper. 9. Fuel contains water or contaminants. Solutions: 1. Fuel pump pressure is incorrect. The output pressure of the fuel pump can be checked by placing a high pressure fuel gauge into the gauge port of the fuel pump.
  • Page 155 Heater ignites but flame is excessive Causes: 1. Fuel pump pressure is too high. 2. Nozzle is worn. 3. Incorrect fuel. Solutions: 1. Fuel pump pressure is too high. Attach a high pressure fuel gauge to the fuel pump and check the pump pressure. Adjust the pressure to the manufac- turer’s specifications with the adjustment on the fuel pump.
