No valve or other obstruction is to be placed between the

Temperature-Pressure Relief Valve and the tank. Do not connect

discharge piping directly to the drain unless a 6” (15.2 cm)

air gap is provided. To prevent bodily injury, hazard to life, or

property damage, the relief valve must be allowed to discharge

water in adequate quantities should circumstances demand. If

the discharge pipe is not connected to a drain or other suitable

means, the water ow may cause property damage.

Water Damage Hazard

Temperature-Pressure Relief Valve discharge

pipe must terminate at adequate drain.

•

CAUTION

T&P Valve Discharge Pipe Requirements:

• Shall not be smaller in size than the outlet pipe size of the

valve, or have any reducing couplings or other restrictions.

• Shall not be plugged or blocked.

• Shall not be exposed to freezing temperatures.

• Shall be of material listed for hot water distribution.

• Shall be installed so as to allow complete drainage of both

the Temperature-Pressure Relief Valve and the discharge

pipe.

• Must terminate a maximum of six inches above a oor

drain or external to the building. In cold climates, it is

recommended that the discharge pipe be terminated at an

adequate drain inside the building.

• Shall not have any valve or other obstruction between the

relief valve and the drain.

Burn hazard.

Hot water discharge.

Keep clear of Temperature-

Pressure Relief Valve

discharge outlet.

The Temperature-Pressure Relief Valve must be manually

operated at least twice a year. Caution should be taken to

ensure that (1) no one is in front of or around the outlet of the

Temperature-Pressure Relief Valve discharge line, and (2) the

water manually discharged will not cause any bodily injury or

property damage because the water may be extremely hot. If

after manually operating the valve, it fails to completely reset

and continues to release water, immediately close the cold water

inlet to the water heater, follow the draining instructions in this

manual, and replace the Temperature-Pressure Relief Valve with

a properly rated/sized new one.

NOTE: The purpose of a Temperature-Pressure Relief Valve is

to prevent excessive temperatures and pressures in the storage

tank. The T&P valve is not intended for the constant relief of

thermal expansion. A properly sized thermal expansion tank must

be installed on all closed systems to control thermal expansion,

see Closed Water Systems and Thermal Expansion on page 13.

regarding the Temperature-Pressure Relief Valve call the toll free

COMBUSTIBLE MATERIAL STORAGE

Fire or Explosion Hazard

Read instruction manual before

installing, using or servicing

water heater.

Avoid all ignition sources if you smell gas.

Do not store or use gasoline or other flammable vapors and

liquids in the vicinity of this or any other appliance.

Use only the gas shown on the water heater rating label.

Keep ignition sources away from faucets after extended

periods of non-use.

Maintain required clearances to combustibles.

Do not expose water heater controls to excessive gas

pressure.

Keep water heater area clear and free of combustible materials,

gasoline and other ammable vapors and liquids.

CONTAMINATED AIR

Breathing Hazard - Carbon Monoxide Gas

Install water heater in accordance with

the Instruction Manual and NFPA 54 or

CAN/CSA-B149.1.

To avoid injury, combustion and ventilation

air must be taken from outdoors.

Do not place chemical vapor emitting

products near water heater.

Breathing carbon monoxide can cause brain damage or

death. Always read and understand instruction manual.

Corrosion of the ue ways and vent system may occur if air for

combustion contains certain chemical vapors. Such corrosion

may result in failure and risk of asphyxiation.

Combustion air that is contaminated can greatly diminish the

life span of the water heater and water heater components such

as igniters and burners. Propellants of aerosol sprays, beauty

shop supplies, water softener chemicals and chemicals used

in dry cleaning processes that are present in the combustion,

ventilation or ambient air can cause such damage.

Do not store products of this sort near the water heater. Air

which is brought in contact with the water heater should not

contain any of these chemicals. If necessary, uncontaminated

air should be obtained from remote or outdoor sources. The

limited warranty is voided when failure of water heater is due

to a corrosive atmosphere. (See limited warranty for complete

terms and conditions).
