SOURCE: Garage Heater

the kerosine heater uses a spark plug for ignition and a photocell to detect flame. at the back end of the blower motor is an air compressor. it is a vane and diaphragm compressor that supposed to put out 3.6 psi of air to the fuel nozzle. the fuel nozzle is a venturi type that creates a vacuum across the orifice to suck fuel from the tank. try this site for spare parts www dot desatech dot com. its the same place I get parts for repairing heaters.

If the unit lights Check the photo cell this can be done with an ohm meter and good light. Should have continuity in light.

SOURCE: reddy heater will not fire.

Your problem is most likely the lack of pressure from the air pump. Your pressure is extremely low. Pressure on a 100k heater should run 5psi. At 3psi there is not enough fuel and not enough air to atomize whats there. Bump the pressure up. If it won't come up, then you have an air leak. Test w/ soapy water. Keep your fingers clear of the fan!

I HAVE A 170 REDDY HEATER THAT RUNS FOR APP.10 MINUTES AND QUITS BLOWING OUT BLACK SMOKE I HAVE CHANGED FILTERS AND CHECKED PRESSURE WAS AT6. PSI CAN YOU GIVE ME ANY HINTS


sounds like you have dirt in your fuel tank, as the heater runas it picks up the dirt in the filter plugging it up. When the heater shuts off, the dirt falls out of the filter. You start the heater back up and it does it all over again. Empty your tank and change the fuel filter. Should be fine then.

Reddy heater model r100a runs approxamitly 15 to 20 minutes then kicks out.fan seems to run fine and already replaced the spark plug.


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

Heater shuts down prematurly


If the heater runs fine for the 15 or so minutes without smoke/odor- do this
  1. check for water droplets on bottom of tank
  2. check for restricted fuel filter
  3. test photocell
  4. test safety control (reset)
You don't state whether this is a spark plug heater *or* Hot Surface Ignitor type. I made the assumption you were inquirung about a Spark Plug Heater. Disregard the list if the heater is an HSI type---- troubleshooting is different.

There are any number possibilities for intermittent running.
1. Bad ground connection at the Ignition Device (transformer, spark box)
2. restricted fuel filter causing fuel starvation
3. crack in the plastic end cover
4. crack in the airline
5. crack in the fuel line
6. crack in the nozzle adapter
7. water in the fuel
8. Others I’m sure I left out

You must be the one to troubleshoot & find the cause.
