Installing the water heater.
The water heater must be installed with the factory supplied draft hood in place.
Venting
Insulation Blanket
Vent connectors must be attached to the
draft hood outlet to connect the water
heater to the gas vent or chimney. The
vent connectors must be the same size
(diameter) as the draft hood or larger,
never smaller.
For proper venting in certain installations
a larger vent connector size may be
needed. Consult the Vent Tables in
Appendix G of the latest version of the
National Fuel Gas Code (ANSI booklet
Z223.1 or NFPA booklet 54.)
Horizontal vent connectors must be
pitched upward to the chimney at least
1/4
″ per foot of length. Single wall vent
connectors must be at least 6
″ from
adjacent unprotected combustible
surface. Vent joints must be securely
fastened by sheet metal screws or other
approved method.
Insulation blankets, available to the
general public, for external use on gas
water heaters are not necessary. The
purpose of an insulation blanket is to
reduce the standby heat loss encountered
with storage tank heaters. This water
heater meets or exceeds the National
Appliance Energy Conservation Act
standards with respect to insulation and
standby loss requirements making an
insulation blanket unnecessary.
The manufacturer’s warranty does not
cover any damage or defect caused by
installation, attachment or use of any
type of energy saving or other unapproved
devices (other than those authorized by
the manufacturer) into, onto or in
conjunction with the water heater. The use
of unauthorized energy saving devices may
shorten the life of the water heater and
may endanger life and property.
The manufacturer disclaims any
responsibility for such loss or injury
resulting from the use of such
unauthorized devices.
CAUTION: If local codes require the
application of an external insulation
blanket to this water heater, pay careful
attention to the following so as not to
restrict the proper function and
operation of the water heater:
● Do not cover the operating or warning
labels attached to the water heater or
attempt to relocate them on the
exterior of insulation blanket.
● Do not apply insulation to the top
of the water heater. This will interfere
with the safe operation of the draft
hood.
● Do not cover the burner access panel,
gas control (thermostat)/gas valve or
pressure and temperature relief valve.
● Do not apply insulation to the bottom
of the water heater or the 2
″ space
between the bottom pan of the water
heater and the floor. This area must be
unobstructed so as not to restrict
combustion air flow to the burner.
● Inspect the insulation blanket
frequently making certain it has
not sagged and is restricting the
combustion air to the bottom of the
water heater. This could result in an
unsafe operating condition.
!
DANGER: Failure to
install the draft hood and
properly vent the water
heater to the outdoors as
outlined in the Venting
section of this manual will
result in unsafe operation of
the water heater causing
bodily injury, explosion, fire
or death. To avoid the risk
of fire, explosion, or
asphyxiation from carbon
monoxide, NEVER operate
the water heater unless it
is properly vented and has
adequate air supply for
proper operation as
outlined in the Venting
section of this manual.
WARNING: If local codes
require external application
of insulation blanket kits
the manufacturer’s
instructions included with
the kit must be carefully
followed.
