CLEARANCES

Minimum clearances between the water heater and
combustible construction are 0 inch at the sides and rear,
4" (102 mm) at the front, and 6" (153 mm) from the vent
pipe. Clearance from the top of the jacket is 12" (305
mm).
A gas water heater cannot operate properly without the
correct amount of air for combustion. Do not install in a
confined area such as a closet, unless you provide air
as described in
obstruct the flow of ventilation air. If you have any doubts
or questions at all, call your gas supplier. Failure to
provide the proper amount of combustion air can result in
a fire or explosion and cause death, serious bodily injury,
Figure
or property damage.
