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 appliance.
Whether replacing an old water heater or putting the water heater in
a new location, the following critical points must be observed. The
water heater must be located:
1. On a level surface. Shim the channel type skid base as
necessary if levelling is required.
2. Near a floor drain. The 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 heater or to lower floors of
the structure.
3. The discharge opening of the temperature and pressure relief
valve 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.
4. Close to the point of major hot water usage and the power supply.
Hot water piping and branch circuit wiring should be as short as possible.
Insulate hot and cold water piping where heat loss and condensation
may be a problem.
Heater construction permits installation, maintenance, and service
work to be performed through the front control panel.
Suggested clearances from adjacent surfaces are 12 inches on top,
30 inches in front for access to the unit.
The heater may be installed on or against combustible surfaces. The
left side and back may be placed flush against adjacent surfaces.
The temperature of the space in which the water heater is installed
must not go below 32°F or above 122°F.
