in an alcove or closet, the entire floor must be covered by the panel.

Failure to heed this warning may result in a fire hazard.

Minimum clearances between the water heater and combustible

construction are 0 inch at the sides and rear, 5.5” (14.0 cm) from the front

and 12” (30.5 cm) from the top. (Standard clearance.) If clearances

stated on the heater differ from standard clearances, install water

heater according to clearances stated on the heater.
Adequate clearance 24” (61.0 cm) for servicing this appliance should be

considered before installation, such as changing the anodes, etc.
A minimum clearance of 5.5” (14.0 cm) must be allowed for access to

replaceable parts such as the thermostats, drain valve and relief valve.
When installing the heater, consideration must be given to proper

location. Location selected should be as close to the wall as practicable

and as centralized with the water piping system as possible.

InsulatIon BlanKets

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. Your water heater meets or

exceeds the Energy Policy Act standards with respect to insulation and

standby loss requirements, making an insulation blanket unnecessary.
Should you choose to apply an insulation blanket to this heater, you

should follow these instructions (For identification of components

mentioned below, see Figure 1). 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 blower assembly.

• Do not cover the outer door, thermostat or temperature & pressure

relief valve.

• Do not allow insulation to come within 2” (5.1 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 combustion air flow.

coMBustIon aIr and ventIlatIon

A gas water heater cannot operate properly without the correct amount

of air for combustion. Do not install in a confined area such as a closet,

unless you provide air as shown in the “Facts to Consider About

Location” section. Never obstruct the flow of ventilation air. If you have

any doubts or questions at all, call your gas supplier. Failure to provide

the proper amount of combustion air can result in a fire or explosion

and cause death, serious bodily injury, or property damage.

FIGURE 5.

If this water heater will be used in beauty shops, barber shops, cleaning

establishments, or self-service laundries with dry cleaning equipment,

it is imperative that the water heater (s) be installed direct vent so that

all air for combustion and ventilation is taken from outdoors.

Propellants of aerosol sprays and volatile compounds, (cleaners,

chlorine based chemicals, refrigerants, etc.) in addition to being highly

flammable in many cases, will also react to form corrosive hydrochloric

acid when exposed to the combustion products of the water heater.

The results can be hazardous, and also cause product failure.

applIances In unconfIned spaces

unconfIned space is space whose volume is not less than

50 cubic feet per 1,000 Btu per hour (4.8 cubic meters per kW) of the

aggregate input rating of all appliances installed in that space. Rooms

communicating directly with the space in which the appliances are

installed, through openings not furnished with doors, are considered

a part of the unconfined space.
In unconfined spaces in buildings, infiltration may be adequate to

provide air for combustion, ventilation and dilution of flue gases.

However, in buildings of tight construction (for example, weather

stripping, heavily insulated, caulked, vapor barrier, etc.), additional air

may need to be provided using the methods described in “Appliances

in Confined Space” that follows.”

applIances In confIned spaces

confIned space is a space whose volume is less than 50 cubic

feet per 1,000 Btu per hour (4.8 cm per kW) of the aggregate input

rating of all appliances installed in that space.
When drawing combustion air from inside a conventionally constructed

building to a confined space, such a space shall be provided with

two permanent openings. ONE WITHIN 12 INCHES (30 cm) OF

THE ENCLOSURE TOP AND ONE WITHIN 12 INCHES (30

cm) OF THE ENCLOSURE BOTTOM. Each opening shall have
