.......they are not safe!
last job of the day i switch on the pump and the heater ignites but the ignition is still sparking.then a loud bang and flash!
turned the gas off,disconnected the gas regulator and took the bottle back to the boat yard and took the heater out of the van when i got home.
ill hold my hands up I WAS WRONG!ive been using these gas heaters on and off for a few years now with a few little niggly problems but nothing like this!
it scared me TBH esp in my new van!
its in my car boot now ready for the tip!lucky escape methinks.
