❑ DO check inlet gas pressure to ensure
that it is within the range specified on the
rating plate.
❑ DO provide adequate air for combustion
and ventilation as discussed in the Use and
Care Manual and the National Fuel Gas Code.
❑ DO maintain proper clearances to
combustibles as specified on the rating
plate.
❑ DO allow enough time for joint cement
vapors to dissipate BEFORE applying power
to the water heater.
❑ DO ensure that the venting system
complies with the guidelines found in the Use
and Care Manual and National Fuel Gas
Code.
❑ DO contact a qualified service technician
if the pilot or main burner will not stay lit. The
burner chamber is designed to be sealed

For increased energy efficiency, some
water heaters have been supplied with
factory installed 3/4” NPT heat traps in
the hot outlet line and cold water inlet
line.
These heat traps may
require a minimum
of one (1) 90
° 3/4” NPT elbow and may
require an additional 90° 3/4” NPT elbow
or a 3/4” coupling depending on your
installation needs. See Illustration of
nipples and heat traps on page 31.
NOTICE: If pipe insulation
is used, ensure that the
thickness does not
exceed ½”. Insulation
thicker than ½” can
interfere with the Blower
Assembly Dilution Air
Holes.
