Just a few rules on gas:
A gas line must come from the outside wall, straight into the house and end
at the stove, in one straight and continuous line. Therefore, no longer is
running it inside a wall cavity, under the house or through the attic,
allowed. Although some of us who are "grandfathered in", and don't have to
rush right out and change it, I'm planning on redoing mine so it's in
compliance.
This necessitates putting the stove on an outside wall or near the outside
wall. If the pipe has to travel a distance to get to the stove, the pipe can't
be put into a wall. It must be run along the wall, instead of inside the
wall. I know this isn't as pretty, but this is to keep a leaky pipe from
filling the wall cavity full of gas. If it does leak, it will be leaking into
the room where you can smell it sooner, is their theory.
There must be a shutoff valve at the stove even if you have one outside.
Use pipe putty or teflon tape. Pipe putty comes in stick form which is
really handy to have. Tighten each connection until it "sings".
The pipe can't have joints except for turns, it must be one continuous piece.
Really, I can't see any reason for ever having a turn inside the house. If it
must turn, do the turning outside, and have the pipe go straight through the
wall to the stove inside. This is uglier having a pipe going up the outside
wall and in, but much safer.
When I'm through installing, I shut off the gas at the the stove and turn it
on at the main. Then I give it a sniff test, all along the line. If I don't
smell gas, I wait 10 minutes and try again. Gas only has 4 lbs pressure
compared to household water which has between 40 and 60 lbs pressure. Gas
pressure isn't even enough to blow up a balloon but the only thing is that it
is thinner than water, so it can more easily slip through joints that aren't
tight enough.
