brad, yes there was a spring that goes into that silver regulator/pilot lite mechanism on the under the fan. replaced it 1st. no need to worry bout the adjustment on it as the propane tank regulator limits the out flow at 10 psi max. as for the the fresh air duct for the flame, i already said i was gona make a plenum to introduce fresh outside air to the flame area and it will be hung from the roof at 8-9 ft from the floor. as for the pilot, it has a sensor the flame keeps at a certain temp, sorta looks like an O2 sensor thats on your car. if the sensor doesn't get proper temp, it shuts off the flow of propane.
like timi says, ive seen these heaters in many body shops, mechanic shops and the biggest problem with having the heater use shop air for the flame, is the FUMES of stuff like paint, carb cleaner, brake clean when HITTING AN OPEN FLAME........STINKS really bad!!!!!!! since i do paint and and work on vehicles, i definitely want that fresh air plenum for the burner. as for running the KILNS FOR HEAT......will work great, but propane is much cheaper.
thank for all the concern, its appreciated.
