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 5). Clean tank and fuel filters (see Fuel Filters, page 11). Fill with clean fuel

2.Replace nozzle (see Nozzle, page 9)
3.Move heater to warmer place until fuel flows freely
4.Clean fuel filters (see Fuel Filters, page 11)
5.Adjust pump pressure (see Pump Pres- sure Adjustment sections, pages 9 and 10)
6.Connect spark plug wire to spark plug
7.A) Adjust electrode gap to .075" (see Spark Plug, page 9)
B)Clean fuel from spark plug with clean, soft cloth
C)Replace plug if heavily coated with carbon (see Spark Plug, page 9)
D)Inspect plug for worn or eroded elec- trodes. If found, replace plug (see Spark Plug, page 9)
8.Check electrical connections and volt- age to solenoid. If good, replace sole- noid valve
