Question about Desa International Kerosene Portable Forced-Air Heater

1 Answer

My DESA C100D kerosene heater quits after running a while. It may

Run for 1/2 hour or 5 min. It just stops heating and eventually the reset will kick off. I think it's running out of fuel to the nozzle. I don't know where to look for the filter and I don't know the theory of fuel delivery in these units. It has a spark plug and seems to have good spark. It ran perfectly until last week. Any help would be appreciated. Thanks in advance.

Emery- there are 2 types of filters used in the spark plug heaters.. Most likely yours is a long cylindrical type which is hidden inside the pickup tube that drops into the tank. These filters tend to get gummed up with a black, tar type goo that restricts fuel flow & starves the flame. The other is a lawnmower type filter. Go to this page for pictures of both types of filter.

The filter is probably the problem. The flame goes out due to lack of fuel, then the photocell shuts the heater down due to lack of flame.

Don't rule out water in the fuel. Water will cause a flameout condition, also.

Hope you'se can help...I have a Desa 60,000 kerosene heater,only ran about 10 hours.Went to start it today,ran for about 1 hour then it quit on me. Motor runs and igniter heats up and shuts off. Took cover...

You need to check the fuel nozzle for a blockage and check the fuel filter. Remove the top of the heater and you should be able to remove the nozzle adapter and the nozzle by turn it until the tabs on the nozzle adapter line up with the holes. One hole is bigger than the other so it will only come out and go in one way. If you remove the nozzle from the adapter and hold the nozzle up to light you should be able to see light through it. Use a piece of small wire or something to clear any blockage.

Grade of fuel required for DESA heater

Dave you can use all three types that you have listed.

The pump is typically set for Number 2/ Diesel Fuel and if you run Kerosene the unit will run a little bit hotter but with a 3E359B you will typically run diesel due to the amount it will use and the increased cost of kerosene over diesel fuel.

Number 1 is similar to kerosene and is the fraction that boils off right after gasoline.
Number 2 is the diesel fuel that trucks and some cars run on, leading to the name "road diesel". It is the same thing as heating oil.

Ready heater forced air 60 kerosene run for 4 min or so and dyes


#2 fuel is too dirty, use #1 or clear K-1.

I have found when running mine in any confined space like a garage, it will consume too much oxygen if not vented. It might run till it draws down the oxygen level. You start at 21% and draw down the oxygen to 14% that is where mine kicks out.

Clean out the filter, flush the tank, put in clean K-1, You might need to replace the igniter. Check your fuel line pressue (mine was 4 psi).
Good Luck

Reset button keeps popping and the time between becomes shorter.

check the photo eye. It's the little rubber boot on the bottom right on the back side of the burner. If it's dirty, it may not be shutting off the igniter. If the igniter runs continuously, the safety breaker will trip.
