Installation and Operation Instructions Manual
WARNING: If the information in these instructions is not followed exactly, a
fire or explosion may result causing property damage, personal injury or death.
– Do not store or use gasoline or other flammable
vapors and liquids in the vicinity of this or any
other appliance.
– WHAT TO DO IF YOU SMELL GAS
• Do not try to light any appliance.
• Do not touch any electrical switch; do not use
any phone in your building.
WARNING
Improper installation, adjustment, alteration,
service or maintenance can cause serious injury
or property damage. Refer to this manual. For
assistance or additional information, consult a
qualified installer or service agency.
WARNING
Install in accordance with all local codes. In the
absence of local codes, refer to NFPA 54 or CSA
B149.1.
CAUTION
The recommended temperature for normal
residential use is 120°F. The dial on the aquastat
does not always reflect the out-coming water
temperature and it could occasionally exceed
120°F. Variation in out-coming temperature could
be based on factors including but not limited to
usage patterns and type of installation.
WARNING
Hotter water increases the risk of scald injury.
Before adjusting the water temperature setting,
read this instruction manual. Temperatures at
which injury occurs vary with the person's age
and the length of exposure. The slower reaction
time of children, elderly or physically or mentally
challenged persons increases the scalding hazard
to them. It is recommended that lower water
temperatures be used where these exposure hazards
exist. Households with small children or invalids
may require a temperature setting less than 120°F
to prevent accidental contact with hot water.
To produce less than 120°F, use point-of-use
temperature limiting devices.
