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 flow may cause property damage.

Temperature-Pressure Relief Valve discharge

pipe must terminate at adequate drain.

•  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 floor 

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.
If you do not understand these instructions or have any questions 

regarding  the  Temperature-Pressure  relief  Valve  call  the  toll 

free number listed on the back cover of this manual for technical 

assistance.

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 flue 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 

hot surface 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).

Install water heater in accordance with

Breathing carbon monoxide can cause brain damage or

death. Always read and understand instruction manual.

For safe operation an adequate supply of fresh uncontaminated 

air for combustion and ventilation must be provided.
An insufficient supply of air can cause recirculation of combustion 

products  resulting  in  contamination  that  may  be  hazardous  to 

life. Such a condition often will result in a yellow, luminous burner 

flame, causing sooting of the combustion chamber, burners and 

flue tubes and creates a risk of asphyxiation.
Do  not  install  the  water  heater  in  a  confined  space  unless  an 

adequate supply of air for combustion and ventilation is brought 

in  to  that  space  using  the  methods  described  in  the  Confined 

Space section that follows.
