Installation Instructions
Locating the New Water
Heater
You should carefully choose an indoor location for the new water
heater, because the placement is a very important consideration
for the safety of the occupants in the building and for the most
economical use of the appliance. This water heater is not for
use in mobile homes or outdoor installation.
Whether replacing an old water heater or putting the water
heater in a new location, the following critical points must be
observed.
1. The location selected should be indoors as dose as practical
to the vent termination point, and as centralized with the
water piping system as possible. The water heater, as all water
heaters, will eventually leak. Do not install without adequate
drainage provisions where water flow will cause damage.
2. The vent piping cannot exceed a total of 35 feet including
vertical and horizontal runs and have no more than 3 elbows.
It cannot slope downward and horizontal runs require ¼" per
foot rise. All horizontal runs require adequate support at
feet intervals.
3. The water heater requires its own (separate) venting system.
It cannot be connected to an existing ventpipe or chimney.
It must terminate horizontally to the outdoors. Whenever
possible terminate the vent on the leaward side of the build-
ing. NOTE: Condensation may be created, at times, as the
combustion gases exit the vent cap and discoloration of
surfaces in proximity to the vent cap may occur.
