The intention of this Troubleshooting Video is to describe the procedure of diagnosing and servicing a Frost Fighter Heater if the burner will not ignite.
Use for FrostFighter IDF and OHV LPNG Units
Procedure:
A. Always make sure gas supply pressure is 14" (1/2 lb) or less as over that amount could cause damage to manifold regulator.
B. Check gas pressure at 1/8" tap on elbow of manifold. Ensure pressure is correct (1.2" for IDF200, 1.8" for IDF350, and 3.0" for IDF500). If no pressure there, remove cover and check for 24v across solenoid valve wires. If voltage present, replace solenoid valve.
C. If no voltage, at solenoid valve, check gas primary control to ensure wired and grounded properly. If wired properly, and still no voltage to solenoid, replace gas primary.
D. Remove the electrode assembly from burner housing. Shut off all manual gas valves then reset the unit. Install jumper wire between terminals 3 and 4. Lay electrode assembly across top of burner housing. Carefully check for spark across the ignition gap after 34 second pre-purge. If no spark, check for 120VAC at ignition transformer. If power there, replace transformer. If no power, replace gas primary. If spark is arching at another point other than the tip of the spark rod, ensure spark rod is in the correct position. If it is then replace spark rod. After test remove jumpers from terminals 3 and 4.
