When installing the heater, consideration must be given to proper location. Location selected should be as close to the wall as practicable and as centralized with the water piping system as possible.

CAUTION

In cold climates provide protection against freeze-up.

THE 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, see Figure 1. The pan should have a minimum length and width of at least 2 inches (51mm) greater than the diameter of the heater and should be piped to an adequate drain.
