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 close 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 tuns and have no more than 3 elbows.
It cannot slope downward and horizontal runs require '/*" per
foot rise. All horizontal runs require adequate support at y/i
feet intervals.
3. The water heater requires Its own (separate) venting system.
It cannot be connected to an existing vent pipe 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.
AWARNING
The power vent water heater requires its own (separate) venting
system. It cannot be connected to an existing vent pipe or chim<
ney. It must be terminated horizontally to the outdoors. Failure to
properly install the venting system can result in asphyxiation, a fire
or explosion and can cause DEATH, SERIOUS BODILY INJURY,
OR PROPERTY DAMAGE.
The water heater comes equipped with a 5 foot power cord
which can be used to connect to a 110/120 volt power
source if (1) local codes allow, and (2) there is a three prong
receptacle available.
AWARNING
Do not use an extension cord. If there is not a suitable recepta­
cle and/or local codes prohibit use of a power cord, field wiring
must be provided.
A CAUTION
WATER HEATERS EVENTUALLY LEAK; Installation of the
water heater must be accomplished in such a manner that if
the tank or any connections shouid leak, the flow of water
will not cause damage to the structure. When such locations
cannot be avoided, a suitable drain pan should be installed
under the water heater. Drain pans are available at your
local Sears store. Such a drain pan must be not greater than
1 '/] inches deep, have a minimum length and width of at least
2 inches greater than the water heater dimensions and must
be piped to an adequate drain. The pan must not restrict
combustion air flow. Under no circumstances is the manu­
facturer or Sears to be held liable for any water damage in
connection with this water heater.
5. The location selection must provide adequate clearances for
servicing and proper operation of the water heater.
AWARNING
INSTALLATIONS IN AREAS WHERE FLAMMABLE UQUIDS
(VAPORS) ARE LIKELY TO BE PRESENT OR STORED
(GARAGES, STORAGE, AND UTILITY AREAS, ETC):
Flammable liquids (such as gasoline, solvents, propane (LP) or
butane, etc.), all of which emit flammable vapors, may be
im|Mt>periy stored or used in such areas. The gas water hotter
pilot light or main burner can ignite such vapors. The resulting
llashba^ and fire can cause deatii or serious bums to anyone in
the area, as well as property damage.
If installation in such areas is your only option, then the installa­
tion must be accomplished in a way that the pilot flame and
main burner flame are elevated from the floor at least 18 inches.
While this may reduce the changes of flammable vapors fmm a
floor spill being ignited, gasoline and other flammable substances
should never be stored or used in the same room or area con­
taining a gas water heater or other open flame or spark produc­
ing appliance.
NOTE: Flammable vapors may be drawn by air currents from
other areas of the structure to the appliance.
AWARNING
Propellants of aerosol sprays and volatile compounds, (clean­
ers, chlorine based chemicals, refrigerants, etc.) in addition to
being highly flammable in many cases, will also change to cor­
rosive hydrochloric acid when exposed to the combustion
products of the water heater. The results can be hazardous,
and also cause product failure.
AWARNING
This water heater must not be installed directly on carpeting.
Carpeting must be protected by a metal or wood panel
beneath the appliance extending beyond the fiill width and
depth of the ^pliance by at least 3 inches (76.2mm) in any
direction, or if the appliance is installed in an alcove or closet,
the entire floor must be covered by the panel. Failure to heed
this warning may result in a fire hazard.
AWARNING
Minimum clearances between the water heater and com­
bustible construction are I" at the sides and rear, 4" at the
front, and 6" from the vent pipe. Clearance from the top of the
jacket is 18" on most models. Note that a lesser dimension may
be allowed on some models. Refer to the label on the water
heater adjacent to the gas control valve for all clearances.
