1.when changing gas bottles make sure you spray the connection with soapy water every time(i use a spray bottle and turn the gas on)if you see bubbling then refit the connection until no bubbling occurs.(after turning the gas off obviously).
2.make sure your gas bottle is really secure in the van with no chance of tipping over.
3.put LPG stickers on the van(2 sides and back of van)
4. fit a flue or if not practical then leave the back door open to let fumes escape when working and fit heater just inside the door to be left open with at least a 12 inch gap at the top.
5.periodically check the gas connection going into the heater(spray bottle again)with it running.
6.buy a good heater(mines an eccotemp L10)from corwoods with heavy duty gas regulator.
7.get the DE right on your controller so it stops the pump shortly after turning water off at brush end.
8.depressurise your heater at the end of your working day by opening up your pole tap after turning off your pump and letting it drain out.
9.in colder weather unscrew the drain screw after doing the above and let it drain.
10.fit a carbon monoxide detector in the van(mines never gone off)
11.when fitting heater on plywood make sure you fit heat proof sheeting on the plywood first.
