Installation (Locating the Water Heater) cont.-
Proper venting practices must be considered when selecting a location for this
water heater. For exact venting specifications, please consult the Venting
section of these Installation and Operation Instructions.
This water heater must be located in an area where leakage of the tank, water
line connections, or the combination temperature and pressure relief valve 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. The drain pan must have a minimum
length and width of at least 4 in (10.2 cm) greater than the diameter of the
water heater and must not restrict proper combustion air flow to the water
heater. The drain pan, as described above, can be purchased from your
plumbing professional. The drain pan must be piped to an adequate drain.
The piping must be at least 3/4 in (1.9 cm) in diameter and pitched for proper
drainage.
It is recommended that a minimum clearance of 4 in (10.2 cm) be provided on
the side of the water heater for servicing and maintenance of the combination
temperature and pressure relief valve.
