are available.
Install water heater in accordance with

the instruction manual.

Breathing carbon monoxide can cause brain damage or

death. Always read and understand instruction manual.

Breathing Hazard - Carbon Monoxide Gas

Insulation blankets are available to the general public for

external use on gas water heaters but are not necessary

with these products. The purpose of an insulation blanket is

to reduce the standby heat loss encountered with storage

tank heaters. The water heaters covered by this manual meet

or exceed the Energy Policy Act standards with respect to

insulation and standby heat loss requirements, making an

insulation blanket unnecessary.
Should you choose to apply an insulation blanket to this

heater, you should follow these instructions. See the Features

and Components section of this manual for identification

of components mentioned below. Failure to follow these

instructions can restrict the air flow required for proper

combustion, potentially resulting in fire, asphyxiation, serious

personal injury or death.

•

do not apply insulation to the top of the water heater, as

this will interfere with safe operation of the draft hood.

•

do not cover the thermostat or the Temperature-

Pressure Relief Valve.

•

do not allow the insulation to come within 2 inches (5

cm) of the floor to prevent blockage of combustion air flow

to the burner.

•

do not cover the instruction manual. Keep it on the side

of the water heater or nearby for future reference.

•

do obtain new warning and instruction labels from the

manufacturer for placement on the blanket directly over

the existing labels.

•

do inspect the insulation blanket frequently to make

certain it does not sag, thereby obstructing the

combustion air flow.

hard water

Where hard water conditions exist, water softening or the threshold

type of water treatment is recommended. This will protect the

dishwashers, coffee urns, water heaters, water piping and other

equipment. See the Maintenance Section in this manual for

sediment and lime scale removal procedures.

A circulating pump is used when a system requires a circulating

loop or there is a storage tank used in conjunction with the

water heater. See Water Piping Diagrams in this manual for

installation location of circulating pumps.
See the Circulation Pump Wiring Diagrams below for electrical

hookup information. Install in accordance with the current

edition of the National Electrical Code, NFPA 70 or the

Canadian Electrical Code, CSA C22.1.
All bronze or stainless steel circulating pumps are recommended

for used with commercial water heaters.
Some circulating pumps are manufactured with sealed bearings

and do not require further lubrication. Some circulating pumps

must be periodically oiled. Refer to the pump manufacturer’s

instructions for lubrication requirements.
