6. Locating the Indirect Water Heater

All water heaters will eventually leak, which can cause property damage. Do not install indirect water heater in a location
that does not have adequate drainage.
• Locate water heater in an area not subject to freezing temperatures.
• Locate water heater in an area where water leakage from the tank or connections will not result in damage to areas adjacent to the water heater or to
lower floors of the structure. When such a location cannot be avoided, a suitable drain pan must be installed under the water heater, and the drain pan
must be connected to a drain.
• The drain pan should be at least 2" deep with a length and width at least 2" greater than the total diameter of the unit and should be piped to an
adequate drain.
• Drain pans are available from your wholesale distributer.
• The life span of an indirect water heater depends on water quality, water pressure, and the environment in which the water heater is installed.
• Water heaters are sometimes in locations where leakage may result in property damage, even when a drain pan is installed and piped to a drain. Such
property 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,
available from some plumbing supply wholesalers and retailers, detect and react to leaks in various ways.
a. Sensors mounted in the drain pan that trigger an alarm or turn off the incoming water to the water heater when leakage is detected.
b. Sensors mounted in the drain pan that turn off the water supply to the entire home when water is detected in the drain pan.
c. 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.
