    So the manual says 5.7 psi and you say 15 quite a difference there...

    Yes, my search was a bit off! I got it from here. Very sorry :(

    Remove the plug from the air filter cover and
    attach an accurate pressure gauge calibrated to a
    maximum reading of 15 PSI.

Reddy heater 170T- terrible fumes-fuel pressure problem

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

Reddy Heater 170T works fine with the cover off but will not ignite with the cover on.

First, heaters with Hot Surface Ignitor technology MUST have the air pump pressure set to factory specs. The onboard computer will not allow any deviation. Proper fuel delivery depends on it.

Now, if the pump pressure is correct, there are no leaks between the pump and the nozzle and no vac leaks on the fuel line, the 90% of the time the problem is a worn nozzle. Desa recommended annual replacement of the nozzle simply because of the wear factor.

More troubleshooting tips

I have an allpro 170T that flames out after a few min. I checked the eye with a meter and it checks OK , The air and fuel and fuel filter Check OK. Took the nozzle apart and it looks OK. Have yet to check...

Being that it will light I will assume air fuel problem. If it were the control board you would not get the heater to fire. Try cleaning the nozzle with carb cleaner and a blow gun and compressor, by simply blowing air thru the nozzle after spraying it good and maybe even soaking it in carb cleaner. Think simple here as these are simple heaters. Have you checked the fuel tank for water? These heaters build condensation when in storage so check the fuel. I empty mine in to a clean five gallon bucket and observe, the fuel is lighter than water so it floats to the top and water sinks to the bottom. If this is the case dry out the tank as best you can and you can siphon off the fuel from the water just be careful not to siphon to much and end up with the water back inside the fuel tank. Check all lines both fuel and air as these dry rot quickly from heating and cooling so many times. Make sure the foam air filter is clean, I use dawn dish soap it works wonderful, just make sure that it is dry before installing. You may even want to test with the air filter out, if it runs correctly you may want to increase the air mixture.

Can you burn diesel fuel

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.

All pro heater runs for a couple of minutes.then

it only shuts down because of an overheating condition or the lack of fuel. if you have an ohm or multimeter, check the ohms on the fan and see if you have any resistance. If you do the fan is good but may still not be putting enough air across the heat exchanger to safely alloww the heater to run without causing a fire.

Is thier a filter that needs to be changed for the fuel system on a 170t

There is a inline fuel filter, small plastic filter-looks like a small space ship located behind side panel.It has a hose attached - one going to tank, one going to nossle

Look below

make sure air and fuel filter are clean.Set pump pressure to mfg set pressure after two minutes of operation

All pro multi fuel

This may sound dumb, but is it full? i have a simupar one and if i start it out at 1/4 tank or ness it will not run long before it shuts off.
