NOTICE
Property damage!
• This water heater must 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, a suitable drain pan must be installed under the water heater.
Such pans must be at least 2 inches deep having a minimum length and
width of at least 2 inches greater than the diameter of the water heater
and should be piped to an adequate drain.
4.4.1 Drain Pan Installation
It is recommended to install a drain pan under the water heater, especially if leaks
can substantially destroy the building structure. In some cases code may even
require it.
Water Heater Size Minimum Required Drain Pan Diameter
50 Gallon 26" (66 cm)
80 Gallon 30" (77 cm)
Table 10
4.4.2 Condensate Drain
The water heater produces condensate during operation which must be drained
properly. Do not use the drain pan but provide proper drainage with a condensate
pump for instance. The condensate does not need to be neutralized. The water
heater comes supplied with a 6 foot long, 1/2 inch diameter drain hose.
