Last spring I bought a Reddy Heater. [50K BTU - uses a bunch of fuels from Jet fuel to Kero]
I used it twice and ran it about 3 hours and it quit. So this fall I checked it over and replaced a burned out ignitor.
The air pressure was 5.5 from the factory, so it reset it to 3.4 like the manual instructed. The service guy said that it was likely that the air pressure caused the ignitor to fail prematurely. He also said that Kero would burn cleaner than the deisel I was using. [and apologized for the $45!!! cost of an ignitor]
So I replaced the ignitor- put Kero in-- and got 2 hours out of the next ignitor.
I don't think I want to mess with any more ignitors.
It's in the shop now [1 year warranty] but I don't intend to spend anything on it.
Why they took a rugged spark plug and replaced it with a fragile ignitor is beyond me. Am I just unlucky or are these things way to fragile for a construction site?
Has anyone had any success converting it back to a reliable plug? [or at least, a not so fragile, and much less expensive plug]
