One minor question we had for the natural gas line was whether or not to
kink the gas hose in an S-shaped curve to trap sediments before they enter
the thermostat.

Do you arrange the gas hose in any particular manner?

Yes. There should be a tee.

It would go something like this: The incoming gas goes to the heater thru
the tee, but at the bottom of the tee is a 6" piece of pipe to catch oil &
other impurities in the gas. tailpiece, drip loop, whatever you want to call
it. The -hose- goes from the tee to the heater; the rest is solid pipe.
