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 standard

Z223.1 or NFPA 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.

Test for spillage at the draft hood relief

opening after 5 minutes of main burner

operation. Use a flame of a match or

candle or smoke. The flame or smoke

should be pulled into the draft hood’s

relief opening(s).

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.

Insulation Blankets

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 door,

jacket door, gas control (thermostat)/gas

valve or pressure and temperature relief

valve.

 DO NOT apply insulation to the bottom

of the water heater or the area where

the combustion air inlet openings are

located. 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 air flow to the combustion

air inlet openings (perforation holes)

located around the lower perimeter of

the water heater jacket. This could result

in an unsafe operating condition.

WARNING: If local codes

require external application

of insulation blanket kits

the manufacturer’s

instructions included with

the kit must be carefully

followed.
