I am installing (green) drywall in a room that has a gas water heater
vented to the outside through a 6" wall. It has a large metal
escutcheon ring around a metal exhaust pipe. The exhaust pipe has an
interior exhaust surrounded by a fresh intake jacket. The pipe gets
warm. Currently there is (no paper) fiberglass insulation. Do I
drywall leaving a large gap around the pipe? Great Stuff expanding
foam? I want this job to look good with safety in mind.

I'd just fit around the exhaust reasonably closely and use the
escutcheon or another one that's more in fitting the decor (if a room
containing the water heater can be said to have "decor" :) ) if that's
an issue...

Aren't there zero clearance flanges for vent pipes? If in doubt, leave
space and use a decorative metal flange to cover gap.

Are you sure it gets warm?

Gas water heater vent pipes usually are double walled - the gap acting as a
heat barrier.

Nevertheless, sheetrock won't burn (note the "rock" part of the name). The
paper covering it might char, but it really won't burn either.

Get from your municipal building permits office the
standard specifications for installing a gas heater.
You will not need a permit because you are not
installing a new fixture, but those two or three
pages of the building code will tell you safe clearances
for various types of interior or finishing wall.
