Question about Reddy Heater-70,000 BTU Kerosene w/T'stat

2 Answers

Reddy Heater R55 55,000 BTU heater spits and sputters but CONTINUES TO RUN. Air pressure is at 3.4 (was 4.0). new lines, Plug is firing well, fuel is old but clean. My question is: is there supposed to be a fuel filter on this model? The black plastic piece in the tank is just hollow. Any ideas on why this unit is spitting and sputtering but continuing to run? Thanks Dave

If you brought the heater to my shop with the great (no lie!) description of the problem we would immediately grab a flashlight, shine into the tank and look for water droplets rolling on the bottom of the than. (Keep in mind that a layer of water can be on bottom & not show up with the light)

The next thing would be to use soapy water and try to find a crack in or around the plastic cover and move all the way to the nozzle looking for an air leak. 3.4 at the gauge doesn't mean the air is going all the way to the nozzle.

Next, remove the top cover. Does the heater run fine once removed? If so, replace the worn out nozzle. That heater has some age on it and DESA recommended annual replacement.

The filter is more of a strainer than a filter. It is hollow.

Not getting fuel after air and fuel filter maintenance.


If the maintenance procedure included anything that required you to dis-assemble the air pump then you must simply re-set the pump pressure in order for fuel to be pumped into the combustion chamber. . It's an easy procedure. Instructions for setting the pump pressure

Reddy heater runs then stops


it's the ignitor itself, if everythingelse is working or new then your just not getting enough spark. Also check your air lines as they do tend to get brittle and if your not getting enough air it won't light either.

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!
