IMPORTANT: 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. Due to the normal corrosive action of

water, the tank will eventually leak after an extended period

of time. Also any external plumbing leak, including those

from improper installation, may cause early failure of the

tank due to corrosion if not repaired. If the homeowner is

uncomfortable with making the repair a qualified technician

should be contacted. A suitable metal drain pan should be

installed under the water heater as shown below, to help

protect the property from damage which may occur from

condensate formation or leaks in the piping connections

or tank. The pan must limit the water level to a maximum

depth of 1-3/4” and be two inches wider than the heater

and piped to an adequate drain. NOTE: The pan must not

restrict combustion air flow. Locate the water heater near a

suitable indoor drain. Outside drains are subject to freezing

temperatures which can obstruct the drain line. The piping

should be at least 3/4” ID and pitched for proper drainage.

Water heater life depends upon water quality, water usage,

water temperature and the environment in which the

water heater is installed. Water heaters are sometimes

installed in locations where leakage may result in property

damage, even with the use of a metal drain pan piped to a

drain. However, unanticipated damage can be reduced or

prevented by a leak detector or water shut-off device used

in conjunction with a piped metal drain pan. These devices

are available from some plumbing supply wholesalers and

retailers, and detect and react to leakage in various ways:

• Sensors mounted in the drain pan that trigger an alarm

or turn off the incoming water to the water heater when

water is detected.

• Sensors mounted in the drain pan that turn off the

water supply to the entire home when water is detected

in the drain pan.

• Water supply shut-off devices that activate based on

the water pressure differential between the cold water

and hot water pipes connected to the water heater.

• Devices that will turn off the gas supply to a gas water

heater while at the same time shutting off its water

supply.

Clearances and Accessibility

NOTE: Minimum clearances from combustible surfaces are

stated on the rating plate adjacent to the gas control valve/

thermostat of the water heater.

The water heater is certified for installation on a

combustible floor.

• IMPORTANT: If installing over carpeting, the carpeting

must be protected by a metal or wood panel beneath

the water heater. The protective panel must extend

beyond the full width and depth of the water heater by

at least three inches (76.2mm) in any direction; or if in

an alcove or closet installation, the entire floor must be

covered by the panel.

• Figure 4 may be used as a reference guide to locate

the specific clearance locations. A minimum of 24 inch-

es of front clearance should be provided for inspection

and service.
