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.

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!

Won't stay on , not very consistent


You don't state whether this heater has the old style spark plug technology or the newer Hot Surface Ignitor technology. Troubleshooting will be different, depending on the style of heater, because the electronics are different.

You ask "what are the two adjustments screw heads on the back of heater". As stated by tros1 these are A. an air pump adjustment screw, and B. a pressure relief valve.


Both technologies require correct pump pressure in order to deliver the fuel at the proper rate. For a pressure setting video

Reply with the model number and/or the specific ignition technology and maybe we can help.

Wont stay running


Reddy suggests: 1. Propane supply may be inadequate 2. High surrounding air temperature causing thermal limit device to shut down heater 3. Restricted air flow 4. Damaged fan 5. Excessive dust or debris in surrounding area solutions are: 1. A) Refill tank B) Provide additional and/or larger tanks. 2. This can happen when running heater in temperatures above 85° F (29° C). Run heater in cooler temperatures 3. Check heater inlet and outlet. Remove any obstructions 4. Replace fan. 5. Clean heater. could not get manual for your exact model but if you want manual for RLP 125 then; http://12.153.20.74/manuals/113893-01C.PDF appears to be the same beast. Hope helps :)
