Why does my blue flame ventless propane heater go out for no reason?

Did the gas man use a manometer when the gas pressure was adjusted up? The three basic types are 1. round needle guage capable of measuring approximately 30" water column pressure, 2. U-tube manometer filled with a clear or red glycol, and 3. digital guage.

It sounds like the gas pressure is a few inches water column too high which could cause the pilot flame to actually lift off the thermocouple tip causing flame failure after the gas valve opens. More is not necessarily better when it comes to gas pressure. Normal propane manifold pressure is around 10.5" w.c. with maximum inlet pressure of 14" w.c. This pressure can be accurately measured with one of the above listed manometers by tapping into the manifold downstream of the gas valve or in the pressure tap on the downstream side of the gas valve. Most normal 100% redundant gas controls have an individual pilot adjusting screw in the valve itself for adjusting the pilot size and pressure independent of manifold pressure.

Dyna glo pro forced air heater won't ignite?

I've had mine for about 8 years now. Just started spitting out fuel and failing to ignite. Took it all apart and found a couple of cracked lines where they went on to the fittings. One was to the air pump and the other was a fuel line at the manifold. Cut them both back and reattached, but it still wouldn't ignite. Then I checked the pressure coming off the air pump and it was at 2 psi, should be at 3.4 on mine. Adjusted the fuel pressure up and bingo, it lit right up as soon as the pressure was right.

My heater starts then cuts out within a minute I've cleaned everything has new fuel whats wrong? its the same as the other posting.

You need to make sure the pressure it correct and that you have no leaks or cracks on the rear cover of the pump.
Sometimes you will get a small crack in the plastic housing and it will cause low pressure.
Check to make sure the photocell is clean and lined up properly to see the flame.
If you hold you finger over the pump adjustment screw you should see the pump pressure go much higher.
