Installing the water heater.
The water heater must be installed with the factory supplied draft hood in place.
Venting
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.
For increased energy efficiency, some
water heaters have been supplied with
two (2) twenty four inch sections of pipe
insulation. Please install the insulation,
according to the illustration on the left,
that best meets your requirements.
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: Application of any
external insulation to this water heater
will require careful attention to the
following:
● 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,
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.
