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.
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 oor 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 oors 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 Combustion
Air and Ventilation on page 11.
9. Locate the water heater where the vent and intake air piping,
when installed, will remain within the maximum equivalent
lengths allowed. See Venting on page 20.
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 starting on page 20.
INSTALLATIONS IN 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 ammable vapors
which can be ignited by a gas water heater’s hot surface igniter or
main burner. The resulting ashback and re 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.
This water heater must not be installed directly on carpeting.
Carpeting must be protected by metal or wood panel beneath the
appliance extending beyond the full width and depth of the appliance
by at least 3” (7.6 cm) in any direction, or if the appliance is installed
