I am trying to install a natural gas fire pit in my flagstone patio. I
am trying to make the pit flush with the surface of the flagstone
(nothing above ground). I have conduit running to the location and a
hole dug, but I'm unsure how to configure the gas lines and valve.
Specifically, all the outdoor fire pits I've seen are above ground,
which makes it easy to access the manual gas valve with a key on the
side of the above-ground portion, below where the ring burner is.
Where I'm doing a flush mount pit, is there a standard solution? I was
thinking about something equivalent to a sprinkler box to access the
valve in a location adjacent to the fire pit (although the sprinkler
box wouldn't look too good in the patio).
Can anybody steer me in the right direction to get this setup?
Also, which gas line should I pull through the conduit? The yellow
flex stuff or the flex stainless (or other)?
