Fitted a new gas stove yesterday as the one I had been using had a leak and had caught fire on two separate occasions which was quite scary. It was a cartridge type stove and the spring on the back of the unit was worn and wasn't pushing the cartridge into the mechanism enough.

Now have a double burner unit bolted through an aluminium plate which bolts through the top of a cupboard unit.
This stove runs off a 4.5 kg gas bottle. Made a box for the bottle and bolted it onto the inside of one of the storage boxes/seat next to the stove. I then ran the gas pipe from the stove behind the seat and connected it to the bottle using a regulator. Turned it all on and there was a gas leak coming from the stove connection. Turned the gas off then tightened the connection up with mole grips, turned the gas back on and there was no leak this time. Lit the stove up and everything works fine.
