You need to check the nozzle for clogs and also check the fuel filter. Let me know what you find and I will tell you some other things to check.

Clean any photocell eye this unit may have. If it continues, replace reset control.

the unit is working exactly as designed , the system is noticing that the unit has not fired so it shuts down so there is not a lot of unburnt fuel everywhere.
try to find out why the unit is not igniting . is the igniter sparking continually

generally if a heater with a spark plug will run for 10 minutes or longer then that’s an indication that the electronics are functioning properly, so for now, eliminate "any fuel delivery problems" before trouble shooting the electronics. The spark plug should spark for the duration of the run time. If the flame goes out the heater shuts down (just like its designed to do). Imagine the fumes & danger involved if the heater continued to pump raw fuel into a hot combustion chamber!

Some possibilities:

1. the plastic end cover is cracked. When the room heats up the crack expands allowing the air pressure to fluctuate.
2. the air pump pressure is not correct. (instructions at www.reddyparts.com )
3. the fuel filter is restricted.
4. the nozzle is restricted or worn.
5. there is an air leak between the pump & the nozzle.
6. water in the fuel. When a droplet passes through there is a momentary flameout condition which will cause the photocell to shut the unit down.
7. The photocell is defective

Some more troubleshooting tips

the air pressure is not set correctly.take a look at the back plate very closly and check to see if you have a crack in one of the plug bosses.if you do the back plate is no good and needs to be replaced.you should also change the adjuster,spring and ball at the same time.now you need to have a gauge to check to see if air pressure is correct.you can not set it with out one.

Model R150A

Old Fuel? Added a Can of Fuel Booster? Used Starter Fluid?
Spark Plug or Igniter?
Gas, Propane, or Kerosene?

You can order it from here.

I would just pull it out and see if you can get at a local auto supply store first.

Good Luck
