LOCATING THE WATER HEATER

Carefully  choose  a  location  for  the  new  water  heater.  The 

placement is a very important consideration for the safety of the 

occupants in the building and for the most economical use of the 

water heater. 

Property Damage Hazard

All water heaters eventually leak.

Do not install without adequate drainage.

CAUTION

Whether  replacing  an  existing  water  heater  or  installing  the 

water heater in a new location observe the following critical 

points:
1.  The water heater must be located indoors.
2.  The water heater must not be located in an area where it 

will be subject to freezing temperatures.

3.  Locate the water heater so it is protected and not subject 

to physical damage by a moving vehicle.

4.  Locate the water heater on a level surface.
5.  Locate the water heater near a floor drain. The water heater 

should be located in an area where leakage of the tank or 

connections will not result in damage to the area adjacent 

to the water heater or to lower floors of the structure. When 

such  locations  cannot  be  avoided,  it  is  recommended  that 

a  metal  drain  pan,  piped  to  adequate  drain,  be  installed 

under the water heater. Drain pan should be fabricated with 

sides at least 2” deep with diameter at least 2” greater than 

diameter of heater. Pan must not restrict combustion air flow.

6.  Locate  the  water  heater  close  to  the  point  of  major  hot 

water usage.

7.  Locate the water heater close to a 120 VAC power supply. 

See Power Supply on Page 18 for requirements.

8.  Locate the water heater where an adequate supply of fresh 

air  for  combustion  and  ventilation  can  be  obtained.  See 

Combustion Air and Ventilation on Page 15.

9.  Locate the water heater where the vent and intake air piping, 

when installed, will remain within the maximum equivalent 

lengths allowed. See Venting Installation on page 25.

10. Do  not  locate  the  water  heater  where  noise  (such  as 

the  Combustion  Blower)  during  normal  operation  will  be 

objectionable in adjacent areas.

11. Do  not  locate  the  water  heater  where  the  subsequent 

installation of the vent (exhaust) or intake air terminations 

would be objectionable due to noise at the termination(s). 

This  includes  locations  close  to  or  across  from  windows 

and doors. See Venting Installation on page 25.

Do  not  locate  water  heater  areas  where  flammable  liquids 

(vapors) are likely to be present or stored (garages, storage 

and utility areas, etc.): Flammable liquids (such as gasoline, 

solvents, propane (LP or butane, etc.) and other substances 

(such as adhesives, etc.) emit flammable vapors which can be 

ignited by a gas water heater’s ignition device or main burner. 

The resulting flashback and fire can cause death or serious 

burns to anyone in the area.

Also, the water heater must be located and/or protected so it 

is not subject to physical damage by a moving vehicle.

When the water heater is installed directly on carpeting, the water 

heater  shall  be  installed  on  a  metal  or  wood  panel  extending 

beyond the full width and depth of the water heater by at least 3 

in (76.2 mm) in any direction or, if the water heater is installed in 

an alcove or closet, the entire floor shall be covered by the panel. 

The panel must be strong enough to carry the weight of the heater 

when full of water.
