Reddy Heater kerosene 110,000 btu . plup it in, fan runs, blows smoke out the front, leaks kerosene also from front, i have cleaned photo cell, replaced plug, cleaned filter and checked lines for cracks,...


Just because there is fuel & spark does not necessarily mean there will be combustion. The fuel must be delivered at the correct pressure, the correct volume, and must be delivered as a fog- not a mist.

My suggestions:
  1. set the pump pressure
  2. be sure the fuel filter is clean
  3. be sure no air leaks or vacuum leaks
  4. Desa recommended annual replacement of the nozzle. They wear out. When was the last time yours was changed?

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...


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.

I have a portable forced air heater Model R55A heater size 55,000/Hr can I use diesel fuel instead of kerosene?


You can, but prolonged use of diesel fuel will burn out the cone faster. Too hot. And it stinks alot worse than kerosene.

Hello, I have a 55,000 BTU kerosene heater, model # R55 It will not fir or ignite when I plug it in. Just paid $10.00 for a guaranteed online answer and have not received one


Take air preassure from a compressor and turn the fan blades in the back of the motor while you reset the switch. the you know its gumming up and needs to be cleanned and changed parts or a kit added from your local lawnmower supply house.

Will not start unless top cover is off


Check that the fan is clean and unobstructed. It sounds like something may be cutting down the air flow. Or the cad eye may be faulty or dirty.
Hope this helps.
