I have a Reddy Heater 125 Multi fuel that I am and have been burning fuel oil in for about 2 years. It just started to make a lot more fumes than it ever did. Any ideas? Thank You Bob

Are you sure there is not water in the tank? Fuel pressure should almost never need adjusted.

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.
  

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.

Is there a fuel pressure gauge on it? IF so it be set to the pressure on the nameplate rating. Mine did samething and I had to replace the rubber hoses from the pump to the injector. Your fuel pressure will tell us whats going on.

It sounds like you are not getting complete combustion and need to adjust the air flow to the burner so it will have more air/oxygen to burn. You may try cleaning the fan and burner also.

Not familiar with the R100B unit. Is it kerosene, propane or something else. Anytime a combustible heater gives off fumes it is not burning the fuel completely. This could be clogged filters, wrong fuel ratio or something else. Send me more info and I will try to solve your problem.

Hi, If this heater is the Reddy 170,000 b.t.u. heater, model # 170t professional series, then yes you can.It is a multi-fuel heater. Fuels it can use are Kerosene, JP8, Jet A fuel, 1&2 Diesel fuel, and 1&2 fuel oil. It must be this model 170T.

no please don't mix. disaster waiting to happen. You will be changing flash point. Do not do it.If kerosene hard to come by ,see if you know someone in aviation that can give you sumped jet fuel.

One of two things, a high heat limit control or the flame sensor, also check your air line that runs to the heater nozzle could be cracked, not enoughair to fuel mix will make it burn dirty.
