Add Lava Rocks and Test Fire Pit

home depot sells these lava rock brands by mr barbecue they're six bucks a piece now the reason why you don't want to use regular rocks is because regular ox when they're gonna heat up they're possibly gonna explode and hurt yourself or somebody else the lining of the plumbing here was a little bit off i had it set up for natural gas not set up for propane propane has an extra attachment which this little air entrainment device port that follows the direction what happens is it mixes the air with the propane to allow for a cleaner burn from my understanding from directions if you don't install this piece right there you would have a little soot built up on your lava rock so i just went back i had to buy a half inch brass coupling right there screw screwed on and now i can thread it back onto our burner and we'll have a nice clean burn [Music]
