Initial Inspection/Disposal Criteria

  1. Visual inspect for missing parts (guards, knobs, etc.) or any structural damage preventing repair. Inspect for torn or cut heater element, damaged or cracked hose/hose connections, loose fittings, and damage to regulators.
  2. Inspect hoses for cracks, inspecting for breaks by flexing.
  3. Inspect hose or valve for foreign material that might cause a blocked line.
  4. Inspect O-rings on supply hose and replace if needed.
  5. Inspect for out-of-round fittings by screwing regulator into tank POL fitting.
  6. Return to stock if item passes initial inspection, passes Testing for Performance, is clean, and is serviceable.
  7. Refurbish heater if any damage is repairable, missing or damaged components are available, and it’s economically feasible to refurbish.
  8. Dispose of heaters that have structural damage that prevents repair. Salvage parts that are serviceable for future repairs. Dispose of damaged regulators and cracked or damaged hoses.

Refurbishing Procedures

A. Cleaning

  1. Clean the outside of the heater using a damp cloth. DO NOT clean the heater by spraying water on it.
  2. Clean the inside of the heater using compressed air.

B. Repair

  1. Replace regulator if there is any damage to the regulator or threads do not properly seat.
  2. Replace or straighten any damaged or bent parts.
  3. Repair or replace auto shut off valve if not working properly (if applicable.)
  4. Replace any damaged or cracked hose or hose connections.

C. Testing for Performance

  1. Prior to testing use an air hose to blow unit off of any dust, dirt or debris.
  2. Perform initial inspections prior to testing.
  3. Ensure a fire extinguisher is in the work area prior to lighting any heater.
  4. Mount or connect the heater to a LP-Gas supply cylinder.
  5. Turn on gas supply to the heater and check all fittings and connections for gas leaks using mild soap and water solution. NEVER INSPECT FOR LEAKS USING A MATCH OR ANY OTHER TYPE OF FLAME. Should a gas leak occur, shut off the gas supply to the heater immediately and wait a minimum of five minutes before repairing the leak.
  6. When assured that there are no leaks, light heater/pilot. If heater/pilot does not ignite within 5 seconds, extinguish flame and shut off gas valve. Wait 5 minutes before retrying.
  7. (#006139 heaters) Once pilot is lit, let run for 3-5 minutes, try on/off cycle 2 to 3 times.
  8. (#006187 heaters) Once pilot is lit, turn heater on, let run for 3-5 minutes; try on/off cycle 2 to 3 times.
  9. If heater fails, determine if economical to repair, send to a certified repair shop.
  10. Inspect auto shut off valve is in working condition by tipping unit over (if applicable.)

D. Repackaging

  • Repack in original carton if possible or pack to local cache option.
