Pilot will not light

  • Air in gas line (hold control knob in on PILOT for a full 2 minutes)

  • Low gas pressure (check tank and regulator)

  • Electrode not creating spark (try lighting pilot with lighter flame) (adjust electrode gap and check ignitor battery)

  • Blockage in pilot orifice (clean)

Pilot will not stay lit

  • Dirt build-up around pilot orifice (yellow flame) (clean pilot)

  • Corroded or faulty thermocouple (replace if pilot flame is blue)

  • Damaged gas valve

  • Winds above 10 mph

Pilot lights but main burner does not light

  • Low gas pressure (check tank and regulator)

  • Blockage in main orifice (clean)

  • Blockage in main burner (clean)


  • If pilot has yellow flame, clear out orifice/pilot area with compressed air.

  • Make sure valve on heater is set to “Off” before turning on tank valve.

  • If pilot has blue flame and heater still will not light it is most likely a bad thermocouple.


  1. Is there sufficient propane gas in the tank? Tank should weigh approximately 40 lbs when full.

  2. Is the tank turned on? If you smell gas check for leaks with a soap-water solution. Replace hose and regulator if necessary.

  3. Has the gas line been fully bled of air by depressing the control knob in the pilot position? This takes a full 90 seconds with a fresh tank.

  4. Is the control knob turned to the pilot position? Control knob should depress about 1/4 inch. Control knob must be in the pilot position.

  5. Is the electronic igniter working properly? Do you need to replace the AA battery? Can the heater be match lit?

  6. Can you see the pilot flame? Does the pilot flame remain after the control knob is released? If not review item #3.

  7. Once the pilot flame is established turn the control knob to the full ON position. The burner flame should have a blue-orange appearance. A lazy yellow flame would indicate a blockage in the burner and will need to be repaired.
