Continued

OBSERVED PROBLEM POSSIBLE CAUSE

REMEDY

Heater will not ignite, but motor runs for a short period of time.

1.A) Fuel tank empty

B)Water in fuel

C)Wrong fuel

2.Dirt in nozzle

3.Very low temperature may cause fuel to thicken and not flow

4.Dirty fuel filters

5.Wrong pump pressure

6.Spark plug wire disconnected from plug

7.Spark plug problems due to:

A)Wrong gap

B)Plug wet with fuel

C)Carbon deposits on plug

D)Damaged plug

8.Solenoid valve not opening

1.A) Add fuel to tank

C)Remove wrong fuel (see Storing, Transporting, or Ship- ping, page 5). Clean tank and fuel filters (see Fuel Filters, page 12). Fill with correct fuel

2.Replace nozzle (see Nozzle, page 10)

3.Move heater to warmer place until fuel flows freely

4.Clean fuel filters (see Fuel Filters, page 12)

5.Adjust pump pressure (see Pump Pressure Adjustment sections, page 11)

6.Connect spark plug wire to spark plug

7.A)Adjust electrode gap to .075" (see Spark Plug, page 10)

B)Clean fuel from spark plug with clean, soft cloth

C)Replace plug if heavily coated with carbon (see Spark Plug, page 10)

D)Inspect plug for worn or eroded electrodes. If found, replace plug (see Spark Plug, page 10)

8.Check electrical connections and voltage to solenoid. If good, replace solenoid valve

WARNING: High Voltage!

9. Damaged electronic ignitor
