I installed a new gas bottle a few days ago for my stove and trying to find out why the following is happening.
When the gas hasn't been used for a few hours, the moment you turn the gas button on the stove there is what looks like a higher pressure wave that comes with a large flame and a 'wooof' sound when the gas ignites.
The the stove works normally. It takes 3-4 hours of not using it for this to occur again.
It looks like there is a pressure buildup in the gas line when it's not in use.
What could be the reason?
