5. Venting is improper. Follow the manufacturer’s recommendations concerning proper venting. Failure to do so can result in heat building up in the
heater until the safety thermostat contacts open and shut the heater off.

6. Nozzle is dirty. If dirt reaches the nozzle, the spray can be adversely affected and cause a shut down. If possible observe the spray pattern and
clean the nozzle as needed.

7. Fuel filter dirty. Check the internal and external fuel filters. Clean or replace as needed.

8. Control board is defective. For the heater to function, the control board must send proper voltage to three components: motor, transformer and
solenoid valve. Using a multi-meter set to measure voltage, check the appropriate control board terminals for proper voltage out to these three
components. If proper voltage to any of these three components is not observed, the control board is defective.

9. Fuel contains water or contaminants. Visually inspect the fuel in the tank for water bubbles or contaminants. Drain, flush, and re-fill as needed.

Heater ignites, but combustion is poor or uneven

Causes:

1. Fuel pump pressure is incorrect.
2. Nozzle dirty or worn.
3. Electrodes damaged or gapped incorrectly.
4. Fuel filter is dirty.
5. Air damper setting incorrect.
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. Use a gauge with enough capacity to measure the high pressure your particular heater can produce. Use the adjustment on the
pump to set the pump pressure to the manufacturer’s specifications.

2. Nozzle dirty or worn. Clean the nozzle using compressed air. Never use anything metal to clean the nozzle as this may enlarge the orifice. With
enough use, fuel traveling under high pressure thru the nozzle orifice can enlarge the orifice. This is especially true when diesel fuel is used. Clean
or replace the nozzle as needed.

3. 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. Adjust or replace the electrodes as needed (page 5/17).

4. Fuel filter is dirty. Inspect the internal and external fuel filters and clean or replace as needed.

5. Air damper setting incorrect. Use the manufacturer’s specifications for the air damper setting and adjust as needed. (see Diagram B, page 17)

6. Whirl disk dirty or mis-aligned. Inspect the whirl disk and clean if necessary. If the disk is warped or mis-aligned, replace or adjust as needed.

7. Ducting is improper. Follow the manufacturer’s recommendations concerning maximum duct length and diameter.

8. Venting is improper. Follow the manufacturer’s guidelines for venting.

9.   Fuel contains water or contaminants. Visually inspect the fuel in the tank for water or contaminants. Drain, flush, and re-fill tank as needed.
