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
B)Check fuel tank for bubbles of water in bottom. If found, remove fuel (see Storing, Transporting or Shipping, page 6). Clean tank and fuel filters (see Fuel Filters, page 14). Fill with clean fuel
C)Remove wrong fuel (see Storing, Transporting or Ship- ping, page 6). Clean tank and fuel filters (see Fuel Filters, page 14). Fill with correct fuel
2.Replace nozzle (see Nozzle, page 11)
3.Move heater to warmer place until fuel flows freely
4.Clean fuel filters (see Fuel Filters, page 14)
5.Adjust pump pressure (see Pump Pressure Adjustment sections, page 12)
6.Connect spark plug wire to spark plug
7.A)Adjust electrode gap to .075" (see Spark Plug, page 11)
B)Clean fuel from spark plug with clean, soft cloth
C)Replace plug if heavily coated with carbon (see Spark Plug, page 11)
D)Inspect plug for worn or eroded electrodes. If found, replace plug (see Spark Plug, page 11)
8.Check electrical connections and voltage to solenoid. If good, replace solenoid valve
