the only way to cook . I took the lava rock out and threw away the burner to make room for the mesquit chunks..
As for gas storage,, state laws may vary HOWEVER N.A.F.P. 54 is the national recognized standard. My copy is at work so I will not quote much , BUT I do know three cylinders is TOO MUCH in a home. easy answer is to buy two and when one dies get the empty out of the house and replace it, you need never run out compleatly.
as for your gas grill cylinder leave it attached to the grill, if you want to have a spare chain it to a tree out of the house. or just leave it out next to a shed.. I am not shure enough to quote but I think putting it in a shed is a bad idea too. I put a small plastic bucket over the valve to keep rain off of it.
