Well, just fired it up. The fan was stuck on the shroud and it only runs true when you put some weight on the housing. hehe, will take a few little mods.
I've had an oil one in the US. When it clogged and got a blow out smoke would billow out. I don't think the LPG one will do that.
I just want to use it every now and again. Primarily to take the chill off when I'm in there for 2 or 3 hours at a time.
