Its especially bad on LP systems with long lines from tank to logs.
We will get folks calling they can not get the logs lite, it happens on nat gas as well, we show up looking all official, pull the trim off, remove the glass, check the pilot assembly, open the lower panel and check gas valve to make sure the shut off valve was not turn, push the pilot and stick my long lighter in the pilot and watch it sputter and then PILOT..
We mention on the phone it can take 3-5 mins of keeping the pilot knob pushed in to expel the "stale" gas. Some take the advise and do ok. Others just want us to come and check the logs anyway..
great way to make money.
So why doesn't it go "stale" in the tank when it's not being used???
Our fireplace has a gas burner at the bottom for lighting the firewood. When I crack the valve open on the wall it takes a few seconds for the gas to fill the pipe and burner. Until it gets there the air being pushed out ahead of it will try to blow the lighter out.
Natural gas and propane don't go "stale".
