Does any one know what size of jet a flamefast cubicle furnace would
have to run on propane the one I,ve brought has a natural gas set-up
it will run on propane but if I could make a replacement jet it would
properly be more efficient its not forced air if that makes a
differance

Thanks Andrew Bishop

quid

Hi Andrew (or anyone else with a flamefast250PB.
My son (a sculptor experienced in hot metals/casting) has just bought one second hand and I am trying to find a manual for it. I would also like to know where to get a gas jet for propane or butane. I see it has an electrical connection too. Is that simply to ignite the gas or does the electric run a fan or something else? If you do have a manual could you scan and send it to me please? Thanks very much, David Thomas

A/ I never managed to get a manual for mine
B/ Although the jet 'should' be changed I've successfully run mine on both
town gas and propane by adjusting the propane regulator pressure
C/ The blower is obviously electric, and there are (two I think) gas
solenoid valves that are electrical.
D/ The way it works is counter intuitive as the gas is sourced via a demand
valve and venturi arrangement whereby the blowing air sucks gas from the
zero pressure demand valve
E/ I've not fired mine up for a year or two
F/ Bits were available from the makers when I set mine up but that must be
15-18 years ago !
G/ Original post (from Andrew Bishop) was back in 2009 !!!!
