R.H. 40,000 kerosene/diesel salamander: sprays,ignites,blows 10 s

Take it back to the Service Centre and ask the guy to "show you how it works, because you can't get it going". Although Kerosene and Diesel are similar, as fuels go they are different. You can combust anything in a Diesel car, but you can't burn anything in a Kerosene heater.

You can find a service manual for that unit at www,desaparts.com and download the PDF.

Hot Surface Ignition Models Service Manual

I am sure you have confirmed that the fuel is fresh and good, no water in it, etc.--
It is kerosene, not #2 Diesel fuel, right?

And the shutting down is good, if the flame does NOT ignite--- :-)
So we have to figure out why the fuel is not getting hot enough to ignite?


Question-- is the oil spray passing close enough to the ignitor?
And this unit does NOT use SPARK to ignite?, correct? --
for most of these heaters have spark ignition.. I am learning all the time, too!

How about checking the fuel pressure. and the air -- is it correct?
Check with your manual how to check and adjust.

After testing these tings, let us know what you learned

It would have to be the igniter,just replace it.

Run ONLY kerosene,#1 diesel fuel if you can tolerate the fumes.Regular diesel will jell up and can't be pumped.

The heater shuts off after 5 seconds because the photocell fails to see a correct flame, in your case any flame at all. That's the photocell's job.

What you are going to have to do is troubleshoot the unit to see if the problem is fuel related or electronics related.

Go to the ReddyParts.com website for troubleshooting tips. This is a good place to start.

The deisel fuel hogged it up. Clean everything out and replace the wick. Deisel fuel is filthy to burn and it needs a lot of airflow.

Dustin, The ignitor only glows for 5 seconds, just long enough to ignite the fuel. The heater is shutting down because the photocell does not see the correct flame color.
Since you say "comes on for 5 seconds", I can only assume that there is a flame. You do not specify a lack of flame. I am also assuming that you have had the heater running this heater season and the problem just started.

YOU must find out if the problem is fuel delivery related or electronics related. Start by checking the pump pressure.

air compressor needs to put out between 3.0 and 3.5 psi of air for proper suction across the nozzle - the nozzle acts as a venturi to create suction or a vacuum.
