Air fuel mixture screw adjustment, forced air kerosene heater

I have a ready heater 3500, and it is out of ajustment, it runs and burns, but it is not adjusted right, The cone at the front of the heater should glow but this one just barely gets red around the edges, Do you know how to set the adjustment screws for the air fuel mixture?

    Can the heater be adjusted to get the fuel smell out all together, or is that just something that you have to live with ? I'm using diesel in my unit which is a lot better than kerosene, but it still has a smell. Thanks

    First thing to do for a stinky heater not burning well is to turn it upside down and empty the tank into a bucket. It likely has an amount of water in it, which cools the flame and results in incomplete burning, which is why it smells and burns cool.

    FYI, only no.1 diesel, no. 1 fuel oil, or kereosene should be used. #2 diesel is dirty fuel and will crud up your heater faster. Also, diesel gels in extreme cold.

Most ready heaters have a fuel pressure setting on the back of the heater near the fan. There should be two small plastic covers, looking directly at the back, the one on the left can be removed and a pressure gauge installed. The one on the right is slotted for adjustment of pressure. I think the correct pressure for that model is 3.0 lbs.

    Fuel pressure adjustment is almost never needed. Try emptying the tank and removing the water in there first.

    rockrat is correct. There is water in the tank, which is causing incomplete burning of the fuel. That is why is stinks and burns cool.

The fuel/air mixture is not right.
  • Start by setting the pump pressure to factory specs.
  • Stop all air/vacuum leaks between the air pump & nozzle
  • If the problem persists, replace the nozzle. Desa recommended annual replacement. Simply stated- the nozzle wears out to a point that the fuel is a spray rather than a fog and the fuel can't burn completely.
  • You don't state the type being burned. Diesel smells more than kerosene.

How to ajust dayton 155000 btu torpedo heater when running smell like kerosen

You say: When running it smells like Kerosene--
That is what you are burning in it, right?

Is it smoking--- like there is a poor combustion mixture?
-- like maybe not enough air pressure?

There is a pressure adjustment for both-- Please check the manual for adjusting the pressures for your particular model.

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.

Heater wont start.Fan goes, Starts to heat, then blows a couple clouds of smoke and dies. Ive cleaned filter, new fuel. Cant figure out what adjustment I should be doing. Glow Plug? What else?

take the shield off and see if it burns with more combustion air. If it does then the heater isnt getting enough air. look for a shutter or set screw near the burner that should be the primary air adjustment. sounds like you have been working on the fuel side already. You may check the orfice to see if it is partially blocked, use a safety pin and gently **** it out. also check the burner tube
