Unburned fuel coming from front nose cone when heating

I have a Reddy Heater R55, s/# 3349330. I had just recently replaced the spark plug because heater would not ignite. After repalcing spark plug unit ran great. I useed the heater tonight, about a week after replacing the sprk plug and i noticed small unburnt dropps of fuel blowing out past the cone onto my floor. I ran the heater and looked at the cone and i see small drops of fuel hiting the inside surface if the combustion chamber after the cone. I have no idea why but it is getting cold here in Minnesota. thanks

In the back of the heater by the filter there should be a screw if yours is like mine screwing it in adds fuel backing it out gives you less make sure filtre is clean because if it isnt it will make it **** more fuel i took the cover off watched the ignitors and adjusted the fuel until it stoped making the jet sound and that is where i left it seems to be burning good there give it a try hope i helped

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?

Can i run diesel fuel in my m50a reddy heater


Yes you can run Diesel in this heater but you will have to turn the pressure up on the back of the pump.
You want the nose cone to be a good glowing orange and with Diesel you may need more air pressure to achieve the proper burning of the heater with the least amount of fumes.

I have a 60,000 btu Reedy Heater runs 5-10 min then shuts off restarts black puff of smoke bad plug ??


Check the fuel filter on the units as well as the inlet and outlet filters on the back of the motor.

Watch the nose cone and see if the end starts to loose the glowing orange color before it quits.
If the unit slowly looses the color then you have a fuel problem but if the unit just quits at full heat then you could have a electrical problem.

Typically the spark plugs on these heaters don't go bad.

Nose not getting red just a little


You need to adjust air/fuel mixture. At the back of the heater there is a plastic slotted set screw. That is the air mixture adjustment screw. Turn it in clockwise a 1/4 turn at a time until the nose cone gets to be about 90% reddish orange. The heater should also burn cleaner. Hope this helps.

I have an older reddy heater pro 100 kerosene space heater,


You Must set the pump pressure quickly! If allowed to run with the nose cone a "bright" cherry red the welds will deterioate to the point that the end will separate from the combustion chamber. Individual sheet metal parts of the chamber are not available.

Reddy Heater runs but will not ignite with bonnet attached.


First, let me say that the general principal of fuel delivery ***to the spark plug*** depends on several things.
  1. Proper air pressure at the nozzle (provided by the rotor/motor)
  2. Proper “fuel pattern” at the nozzle (provided by the rotor/motor/nozzle)
  3. Proper amount of ***air & fuel*** at the nozzle (provided by the rotor/motor/nozzle)
  4. Proper ***air flow (cfm) through the combustion chamber (provided by the fan blade/motor)
  5. Proper rpm’s of the motor, which affects all of the above.

On your heater the first step is to set the air pressure to specs. Instructions are on the www.reddyparts.com website. This pressure setting directly affects fuel delivery & fuel atomization

This nozzle rule will only apply if everything is correct as far as fuel delivery applies. The pump pressure must be correct- not almost correct. Set the pressure with a low-pressure gauge that registers12-15 psi max. A gauge with a higher scale just will not read close enough to satisfy the system. If the pressure is not correct, the above rule will not apply. Instructions for setting the pressure can be viewed at http://reddyparts.com/pressure.htm.

  • Next, if the fan is OK (correct & intact) look at the NOZZLE. DESA recommends annual replacement of the nozzle, which is a wear item. Naturally, annual usage varies, so, wear will depend on annual usage. A worn nozzle produces a cone shaped SPRAY rather than a cone shaped FOG. A spray drowns the spark, where a fog gets ignited, provided it contacts the spark. ALSO, the pattern from a worn nozzle can completely miss the spark (combustion??? Hardly!). When the top is lifted the change in airflow allows a false correction in the combustion chamber, allowing combustion, but when the top is replaced the flame is extinguished. A restricted nozzle or a restricted fuel filter will also distort the fuel pattern and create the same symptom. Also, like the fan blade, make sure that the correct nozzle is installed. Nozzles get swapped, too.

Silvercliff- since you use the word “plug” I am assuming that you have a spark plug type heater, not the new technology HSI type (hot surface ignitor) that uses a glowbar and an onboard computer.

Reddy heaters are simple to troubleshoot, but you must understand how the system operates.

Since you state that the heater produces a fog at startup indicates that you are getting “some” fuel.

Obviously, the fuel is not igniting.

Now, you must determine if there is any spark. Is a good spark arcing across the electrodes on the plug? If not, is spark being produced by the Ignition Control unit (aka spark box, transformer) ? If not, is the Safety control (reset) sending electricity to the Ignition Control unit?

If there is a good strong spark at the plug, then you are having a fuel delivery problem, even though there is “some fuel”. Understand that the amount of fuel being delivered to the nozzle is DIRECTLY related to the air pump pressure. If the air pump pressure is not correct, then the fuel delivery is not correct. Setting the pump pressure is not difficult. Pump pressure is CRITICAL. Instructions for setting the air pump pressure can be found at www.reddyparts.com .

If the air pump pressure is correct, then check the following:
  1. Cracked air line preventing correct pressure at the nozzle.
  2. Cracked nozzle adapter preventing the fuel from being SUCKED from the tank.
  3. Clogged fuel filter.
  4. Restricted or worn nozzle. The fact that your heater is a spark plug type heater indicates that it has some age on it. DESA recommends annual replacement of the nozzle. Are you using the original nozzle? Worn nozzles produce a SPRAY. New nozzles produce a FOG. The nozzle produces a cone shaped fog. If the cone is missing (not hitting) the spark, for some reason, then there will be no ignition.
  5. Finally, and don’t laugh, is your fuel 100% kerosene or diesel? Water sinks to the bottom of the tank. The heater draws fuel from the bottom. If there is an inch of water on the bottom…….., well, water will not ignite.

I hope this helps.

www dot desatech dot com is a parts distributor for reddy heat products. on their main page they have a short troubleshooting guide. the motor needs to provide 3.5 psi of air across the fuel nozzle to suck the fuel out of the reservoir. check your ignition source (spark plug, hot surface igniter) if the hot surface igniter is broken get a new one, if the spark plug don't spark, check the gap might be too big. see if the spark plug is grounded. poor grounds will cause intermittent sparking. check the high voltage wire for breaks in the insulation, might be shorting out to ground BEFORE the plug. gap should be 75 thousandths.
