WARNING:

Improper installation, adjustment, alteration, service

or maintenance can cause serious injury or prop-

erty damage. Refer to this manual. For assistance

or additional information, consult a qualified installer

or service agency.

WARNING:

If the information in these instructions is not fol-

lowed exactly, fire or explosion may result and can

cause property damage, personal injury or death.

WARNING:

Follow minimum combustible clearance as noted

on water heater label. Do not install on combustible

flooring (see Figure 2, Page 3). Install in accor-

dance with all local codes. In the absence of local

codes, refer to NFPA 31 or ANSI Z21.10.1.

CAUTION:

The recommended temperature for normal residen-

tial use is 120°F. The dial on the aquastat does not

always reflect the outcoming water temperature,

which could occasionally exceed 120°F. The varia-

tion in outcoming temperature could be based on

factors including but not limited to usage patterns

and type of installation. Test your water at the tap

nearest to the water heater. (See page 5 for mea-

suring the outcoming water temperature).

WARNING:

Hotter water increases the risk of scald injury. Be-

fore changing the temperature setting, read the

instruction manual. Temperatures at which injury oc-

curs vary with the individual’s age and length of

exposure.
The slower reaction times of children, elderly and

physically or mentally impaired persons increases

the scalding hazard to them. It is recommended lower

water temperatures be used where these situations

exist.
Households with small children or invalids may re-

quire a temperature setting less than 120°F to prevent

accidental contact with hot water.
To lower water temperature use point-of-use tem-

perature limiting devices.

WARNING:

Flammable vapors may be drawn to this water heat-

er from other areas of the structure by air currents.
Do not store or use any flammable liquids in the

vicinity of this heater.

WARNING:

Water heater blankets may restrict air flow to the

heater and cause fire, asphyxiation, personal injury

or death.
