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 12 (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.

WARNING: Risk of scalding and property damage.

▶ Precautions must be taken prior to manually

operating the relief valve to avoid contact with hot

water discharged from the relief valve and to prevent

water damage.

NOTICE: Appliance damage!

▶ Label all wires prior to disconnection when servicing

controls. Wiring errors can result in improper and

dangerous operation. Verify proper operation after

servicing.

WARNING: System damage!

▶ If a relief valve discharges periodically, this may be

due to thermal expansion in a closed water supply

system. Contact the water supplier or local plumbing

inspector on how to correct this situation. Do not

plug the relief valve.

WARNING: Property damage!

▶ If the water heater is used in a space heating

application, all piping and components connected to

the water heater must be suitable for use with

potable water.

WARNING: Personal Injury from toxic chemicals.

▶ Toxic chemicals, such as those used for boiler

treatment, shall not be introduced into the potable

water used for space heating.
