I need to run a gas (LP) line from outside the house to a cooktop in the kitchen. Here's what I think I need to do:
- drill a hole in the exterior wall and the header (from the attic) of the same wall
- connect a 90° joint to Corrugated Stainless Steel Tubing (CSST), drop it through the hole drilled in the header and fish it through the hole in the exterior wall
- connect a short piece of black pipe to the elbow, and connect it to the regulator installed by the propane supplier
- the other end of the CSST would run through the attic and down through another hole in the header of the kitchen wall
- connect to cooktop (I will, of course, use the supplied conversion kit)
This is the plan I've assimilated from research, much of it conflicting. So I'm sure it needs some adjustments. Here are my questions:
- from what I've read CSST is the way to go, but how do you protect it from fasteners going into the wall?
- I assumed short legs of black pipe should be used at the ends, since it probably looks better coming out of the wall, unless...is there some kind of wall plate/jack that could be used?
Is this approach generally sound? Anything else I should consider?
