MAINTENANCE AND STORAGE
WARNING. To prevent personal injury, unplug the heater from the wall outlet before servicing.
For maximum efficiency and trouble-free service, make the following periodic maintenance, cleaning and inspections.
DAILY SCHEDULE
1.GENERAL. Make general visual inspection of heater for loose or damaged parts. Check nuts and bolts to insure against looseness caused by vibration or rough handling. Damaged parts should be repaired or replaced before using heater again. Check heater operation to be sure it is operating normally (See "Servicing" section for description of normal operation).
2.FILTERS. Dirty air or fuel filters will cause an imbalance in the air-fuel mixture. The best indication that this condition exists is an increase in odors or difficulty getting your heater to ignite. This heater should never be operated without the filters in place. If required, clean filters as described under "500 Hours" and "Annual Schedules".
500 HOUR SCHEDULE
1.AIR INTAKE FILTER. Remove and wash the filter element with a mild detergent, dry thoroughly and replace. Do not oil the filter element. If your heater is used where there is considerable dust or dirt, clean as often as necessary (approximately every 50 hrs.).
2.REMOVE DUST. Clean heater twice a season (more often under dusty conditions). Remove accumulated dust from the transformer, burner, motor and fan blades with compressed air. Wipe area clean with a clean dry cloth. Inspect area to insure all foreign materials are removed, especially around the burner and combustion area.
3.CAD CELL. Clean the glass portion of the cad cell with a soft dry cloth.
4.NOZZLE. 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 and excess odor and smoke. If this occurs, replace the fuel nozzle.
5.FUEL TANK. Clean twice a season (during frequently used periods, clean twice a month). Drain and flush the fuel tank with clean fuel oil.
ANNUAL SCHEDULE
1.AIR OUTPUT FILTER. Remove the air output filter and tap the contaminated side gently on a solid object to remove contaminates. Compressed air or liquids should not be used to clean this filter. Reinstall cleaned filter in filter body in the same position as it was when removed. If the filter appears extremely dirty, replace it with a new filter of the same type. When replacing the filter cover, be sure the gasket is firmly in place and the screws in the filter cover are tight to prevent air leaks.
2.FUEL FILTER. Remove the fuel filter from fuel line and direct compressed air through the filter in the opposite direction of fuel flow. Safety glasses should be worn when using compressed air.
3.AIR AND FUEL LINES. If the air or fuel lines are removed during cleaning, be sure all connections are tight before operating unit.
4.AIR PRESSURE SETTING. The air pressure has been properly set at the factory. If the air pressure is out of adjustment, it will most likely be caused by dirty air filters, a partially plugged nozzle, an air leak in the system or improperly set pressure. If adjustment becomes necessary, first determine the proper pressure setting for your heater which is printed on the serial label located on the fuel tank. Remove the plug from the air filter cover and attach an accurate pressure gauge calibrated to a maximum reading of 15 PSI. Start the heater and note the pressure reading. If the pressure is low, slowly turn the pressure adjusting screw in (Clockwise) until the correct pressure is obtained. If the air pressure is high, turn the adjusting screw out (counterclockwise) until the pressure is correct. When correct pressure is reached, unplug the heater, remove the gauge and replace the plug.
STORAGE
Store the heater in a dry location free from fumes or dust. At the end of each heating season, clean the heater as described in the MAINTENANCE section. Drain and flush the fuel tank with clean fuel. The manufacturer recommends completely filling the tank with fuel for extended storage to minimize condensation inside the tank.
SERVICING
A hazardous condition may result if a heater is used that has been modified or is not functioning properly. When the heater is working properly:
*The flame is contained within the heater.
*The flame is essentially yellow.
*There is no strong disagreeable odor, eye burning or other physical discomfort.
*There is no smoke or soot internal or external to the heater.
*There are no unplanned or unexplained shut downs of the heater.
DIAGNOSTIC FLAME CONTROL:
This heater is eqiupped with a diagnostic control board and flashing LED error indicator. This flashing LED signals when there is a Malfunction of a monitored component. See the following diagnostic Guide for error signal and a brief description of the error:
LED | UNIT OPERATION |
Show Flash | System lockout-High temp limit or rollout |
........................... | switch open |
2 Flashes | System lockout-flame exist before motor |
.......................... | starting |
4 Flashes | System lockout-motor no normal operation |
5 Flashes | System lockout-RESET KEY error |
6 Flashes | System lockout-failled to detect flame |
Steady Off | Waiting or normal operation |
Steady On | Ignition control failure |
