IMPORTANT INFORMATION
The equipment must be installed in accordance with
those installation regulations required in the area
where the installation is to be made. These regulations
must be carefully followed in all cases. Authorities
having jurisdiction shall be consulted before
installations are made.
All wiring on water heaters installed in the USA must
be in accordance with the National Electrical Code and/
or local regulations; or in Canada, installed in

substantial property damage.
INSTALLATION & SERVICE MANUAL
DANGER
Indicates a potentially hazardous situation, which, if
not avoided, may result in moderate, or minor injury
or property damage.
Indicates a potentially hazardous situation, which, if
not avoided, could result in death, serious injury, or
substantial property damage.
NOTICE
Indicates special instructions on installation,
operation or maintenance, which are important but
not related to personal injury hazards.
DO NOT store or use gasoline or other flammable,
combustible, or corrosive vapors and/or liquids in the
vicinity of this or any other appliance.
IF YOU SMELL GAS:
DO NOT try to light any appliance.
DO NOT touch any electric switch; do not
use any telephone in your building.
Immediately call your gas supplier from a
telephone in another building. Follow the
gas supplier's instructions.
If you cannot reach your gas supplier, call
the fire department.
DO NOT OPERATE THE APPLIANCE UNTIL
THE LEAKAGE IS CORRECTED!
Liquefied petroleum gas/propane gas is heavier than
air and will remain at floor level if there is a leak.
Basements, crawl spaces, closets, and areas below
ground level will serve as pockets for accumulation
of leaking gas.
This water heater is supplied with an adjustable
thermostat to control water temperature. Hot water
temperatures required for automatic dishwasher and
laundry use can cause scald burns resulting in serious
personal injury and/or death. The temperature at
which injury occurs varies with the person's age and
the time of exposure. The slower response time of
disabled persons increases the hazards to them.
NEVER allow small children to use a hot water tap
or to draw their own bath water. NEVER leave a
child or disabled person unattended in a bathtub or
shower.
