LOCATING THE NEW WATER HEATER
FACTS TO CONSIDER ABOUT THE LOCATION
The water heater should be located as close as possible
to/or centralized to the water piping system. The water
heater should be located in an area not subject to freezing
temperatures.
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 heater or to lower floors of the structure.
When such locations cannot be avoided, a suitable drain pan
should be installed under the heater.
Such pans should be at least two inches deep, have a
minimum length and width of at least two inches greater
than the diameter of the heater and should be piped to an
adequate drain.
Drain pans suitable for these water heaters are available
from your distributor, dealer or manufacturer listed on the
rating plate.
Water heater life depends upon water quality, water pressure
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 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 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
leakage 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
how 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
A minimum clearance of 4" must be allowed for access to
replaceable parts such as thermostats, drain valve and relief
valve.
Adequate clearance for servicing this water heater should be
considered before installation, such as changing the anodes, etc.
