There is an air pump on the back of the fan motor. The plastic cover is probably cracked, allowing the air pressure to escape. This pump causes the nozzle to siphon fuel from the tank and MUST privide the rated pressure indicated on the data plate of the heater. Spray soapy water on this cover to check for leaks while the motor is running. You will need to remove the end and top covers to do this. If leaking, it may need to be tightened a bit, or if cracked you will need to replace the cover. Set pressure when replacing the cap with a low pressure gage.

My unit is a kerosene 35000 btu unit...just had similar issue.
It is very possible that the spark plug is

  1. fouled out (dirty)
  2. mis-gapped
take the top cover off, you will see the plug. There is a sheetmetal plate held on by two screws holding the ground, plug, and nozzle together. It is easier to just remove the plate (you will have problems with the plug nut if you don't).

remove the plug with a plug socket, probably 5/8.
I used brake parts cleaner to spray off the electrode of the plug then a wire brush to clean it.

check your plug gap...this might be crucial. my gap was specified on a label stuck on the inside of the bottom of the body. The plug on my unit was way too small. Adjust gap if necessary using feeler guages.

reinstall parts and plate. (I actually tack-welded the plug nut into place for ease of maintenance later). Note that the electrode needs to be a specific angle, relative to nozzle....probably diagrammed on the same label as the gap spec.

replace top and see if she'll fire up.

...last note...also might check your fuel pickup/filter. It is located behind the side panel in the unit

good luck...hope I have helped you

When plugg in fan turns about a 1 second and stops. Used to work fine last year actually used it couple times this year too what seems tobe the problem thank you

sounds like an ignition problem. The fan is supposed to start first to get the airflow going, then the igniter should heat up (glow igniters) or start sparking (spark plug igniters), then the fuel starts pumping. If the igniter is not working the fuel won't start. Things to check.... igniter - see if it is intact, fuse (usually in the circuit board), If those are ok, then check fuel pump, fuel filter, air filter. Hope this helps.

Heater used once 3 yrs ago. Now wont start.

When the heater hums is the fan turning. If it is I would add more Kerosene. There is no shut off but the Kerosene is sucked out a tube from the top of the tank. This tube does not reach quite all the way to the bottom of the tank. Your heater should hold about 9 gallons if it is empty. A couple of gallons would give it plenty to run though. Let me know.

Kerosene does not get stale or go bad like gas. I would make sure the tank is close to full to prevent condensation and just put it away in a dry place. I have stored over 50 each year for many years and have never had any problems.

check your air lines that go to the burner nozzle for any breaks and clean all of the filters.
