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
appliance.
CAUTION
Property Damage Hazard
•
All water heaters eventually leak.
•
Do not install without adequate drainage.
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, adequately drained, be installed under the
appliance.
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 14 for requirements.

8. Locate the water heater where an adequate supply of fresh
air for combustion and ventilation can be obtained. See Air
Requirements on page 18.
9. Locate the water heater where the vent and intake air piping,
when installed, will remain within the maximum equivalent
lengths allowed. See Venting requirements on page 24.
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 22.
Fire or Explosion Hazard
Do not store or use gasoline or other flammable vapors and
liquids in the vicinity of this or any other appliance.
Avoid all ignition sources if you smell gas.
Do not expose water heater controls to excessive gas
pressure.
Use only the gas shown on the water heater rating label.
Maintain required clearances to combustibles.
Keep ignition sources away from faucets after extended
periods of non-use.
Read instruction manual before
installing, using or servicing
