Question about Reddy Heater-170,000 BTU Kerosene Deluxe

1 Answer

Still stumped tbugger

Took the cover off, replaced the fuel line with a clear one, fuel does notsiphon into the nozzle right away, 2nd or 3rd try (plugging in unit).Runs great...
Is there supposed to be some kind of in-line check valve to keep the fuel from returning into the tank? took off brass fittings and Teflon taped them inspected nozzle plate (no cracks), put old nozzle back in re-started unit, same thing the fuel doesn't get to the nozzle quick enough or is there some other type of vacuum leak?

Thanks Hojo

If your heater has a plastic nozzle adapter - check for a crack at its base. There could be either a vac leak- or a pressure leak at this point.

There is no check valve. And there is supposed to be a slight delay ( 2-3 seconds, maybe) in fuel pick up, but it sounds excessive, in your case.

One time, this is true, a do-it-yourselfer engineer had a similar problem. He had put a hardware store hose on his fuel pick up. The I.D. of the hose was slightly larger that factory specs, but it was all he could find. He fought the problem until he put his pencil to the weight of the column of liquid that the pump was attempting to lift, figured the column was too heavy, so he ordered a factory spec'd fuel line and that solved his problem, so he says.

Here's another wierd one. A customer brought a new heater into our shop for warranty. He was having a similar problem. Our veteran mechanic found that the nozzle had been factory overtightened into the nozzle adapter and the o-ring on the nozzle was partially restricting the fuel entry hole of the nozzle adapter. Now you know why we called him "Moses". He could work miracles.

You have a minor problem thats going to be hard to find. Just keep plugging away.

The fuel level sensor in the tank is not linear, meaning it doesn't have the same equally spaced indication between E and F . The shape of the tank has a lot to do with the reading also. The needle will move more rapidly when the tank is below 1/2 full. When the low fuel light comes on there should be almost 3 gallons left in the tank 2 1/2 which are usable.

Ok if they have hooked a tranx box or something similar to the truck and you dont have the problem then that means the computer is comanding this downshift activity.This does not mean the computer is bad only that some piece of data that it needs to make a decision with is faulty.There are four basic inputs that the computer needs,1 engine rpm( crank shaft sensor or tach signal from distributor)2 Engine load ( map sensor ) 3 Throttle opening / engine torque ( tps/fipl/map)4 road speed (vehicle speed sensor). my guess would be either a bad tach signal which would probaly not affect the way the engine runs or a bad map sensor.The problem with these early model E4OD transnissions was there is not much live data availiable from the onboard computer and you really need a breakout box to diagnose one of these types of problems.Good luck let me know if i can help.

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.

I have ready heater 150, 000 btu, the fan is blowing strong and there is constant fire comeing from sparkplug , but its not igniting. What could be wrong.

No fuel!! Several things can cause this, empty fuel tank, dirty fuel filter, plugged screen in the nozzle assembly,or plugged nozzle. So lets clean up the fuel system by first removing the top section of the heater and exposing the burner tray. Remove the tray and locate the fuel nozzle, remove the nozzle, now they say you can not clean them, I say with a q-tip, tooth pick and carb cleaner you can just be careful not to damage the nozzle. Behind the nozzle is a screen assembly these corrode at times so clean it up too. Below the nozzle assembly is the flame sensor, clean this with windex and a soft terry cloth rag, make sure it will have a clear unobstructed view of the flame.Put the nozzle assembly back together, and now inspect the fuel line for cracks, holes,and dry rot replace if necessary. Trace the lines down to the side where they come thru the case. Remove the side cover and locate the fuel line and in line filter, remove the filter. Cleaning this is easy you need a compressor and blow gun, all you do is blow air backwards thru the filter and instantly its clean. Inspect fuel lines and reassemble. Now make sure that you have clean fuel in your tank, and there is no water in it as well.Plug it in and you should now be heating like new. If not it could be your fuel pump!

Check your fuel lines and most models have a fuel filter in line. A few things come to mind one how old is the fuel? Check the screen in the nozzle assembly by removing nozzle it sits directly behind the nozzle, these corrode and affect fuel flow. While you have this tore down clean the fire-eye with windex and terry cloth rag, it may not be seeing the flame. Check the air filter at the back of the heater as well. These are common problems with these heaters.

Reddy heater will not fire.

Your problem is most likely the lack of pressure from the air pump. Your pressure is extremely low. Pressure on a 100k heater should run 5psi. At 3psi there is not enough fuel and not enough air to atomize whats there. Bump the pressure up. If it won't come up, then you have an air leak. Test w/ soapy water. Keep your fingers clear of the fan!
