What a Sunday morning surprise: leaking hot water heater. I've known this
day was coming and dreaded it, since the gas supply pipe for the hwh runs
from a corner, through a cold air return, over the fuse box then down to the
hwh. I'm sure this not acceptable, kind of thing that makes the fire
marshall wake up screaming, but I have a couple questions on how to properly
reroute the line. I'd like to drop the gas pipe down so it passes under the
cold air return and the fuse box, at which point it will be roughly shoulder
height off the floor( for a 5'8" guy). Question 1: what is legal/ prudent
clearance for a gas pipe passing a fuse panel?
Question 2: I notice all my gas lines run along the ceiling and drop only
when they reach the appliance: is this standard/required? My last question
concerns the dead end stub just before the pipe meets the valve: is there a
standard or agreed upon distance the pipe should drop vertically before it
makes that bend into the valve?
I'd appreciate any comments or directions to FAQs
If the line passes thru the return without fittings, it may not
be a problem. Can run past the panel without concern.
"Drip Leg" looks like this:
(copper line is shown, but drip leg is same)
Use a nipple of roughly 3" length.
Shut off valve is ahead of the drip.
