For your safety
▶ Do not store or use gasoline or other flammable,
combustible or corrosive vapors and liquids in the
vicinity of this or any other appliance.
DANGER: Fatal accidents!
Carbon monoxide poisoning.
▶ Carefully plan where you install the
heater. Correct combustion air supply
and flue pipe installation are very
important. If a gas appliance is not
installed correctly, fatal accidents can
result such as carbon monoxide
poisoning or fire.
DANGER:
Carbon monoxide poisoning.
▶ Exhaust gas must be vented to outside
using approved vent material. See table
5, page 13 (In Canada use only
ULCS636 approved material). Vent
and combustion air connector piping
must be sealed gas-tight to prevent flue
gas spillage, carbon monoxide
emissions and risk of fire, resulting in
severe personal injury or death.
Approved vent terminations must be
used when penetrating to the outside.
DANGER: Electric shock!
▶ Field wiring connections and electrical
grounding must comply with local
codes, or in the absence of local codes,
with the latest edition of the National
Electric Code, ANSI/NFPA 70, or in
Canada, all electrical wiring must
comply with the local codes and the
Canadian Electrical Code, CSA C22.1
Part 1.
DANGER: Electric shock!
Shock hazard: line voltage is present.
▶ Before servicing the water heater,
unplug power supply cord from outlet.
Failure to do so could result in severe
personal injury or death.
WARNING: Damage to the appliance from over
pressure.
▶ The heater must be disconnected from
the gas supply piping system during any
pressure testing of that system at test
pressures equal to or more than 0.5
psi.
NOTICE:
▶ The appliance should be located in an
area where leakage of the heater or
connections will not result in damage to
the area adjacent to the appliance or to
lower floors of the structure. When
such locations cannot be avoided, it is
recommended that a suitable drain
pan, adequately drained, be installed
under the appliance. The pan must not
restrict combustion air flow.
WARNING:
▶ The maximum inlet gas pressure must
not exceed the value specified by the
manufacturer and the minimum value
listed is for the purpose of input
adjustment.
NOTICE:
▶ If a water heater is installed in a closed
water supply system, such as one
having a backflow preventer in the cold
water supply line, means shall be
provided to control thermal expansion.
Contact the water supplier or local
plumbing inspector on how to control
this situation.
WARNING: Fire danger!
▶ Keep appliance area clear and free from
combustible materials, gasoline and
other flammable vapors and liquids.
NOTICE:
▶ Do not obstruct the flow of combustion
and ventilation air.
NOTICE: Appliance malfunction!
▶ If power is lost while appliance is
operating. Turn off both water and
power for 15 seconds to reset device.
