A word of advice always make sure that the connection from the gas to the cadac is screwed tightly with a spanner or plyers. We had an accident with our Cadac on Tuesday night where there was a light back and it ignited the plastic casing around the ignition button. Having tightened the nut with a spanner we are not sure what caused this but having spoke to Cadac they have said there must have been a gas leak. Cadac customer services have been fantastic and are replacing the full burner without charge even though it was only the plastic casing that was damaged. Great customer service.
