American (A)BCL3100T2506NOX, Instruction Manual

14

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.

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 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.

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 flammable 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 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  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).
