Installation Instructions (cont'd)
Filling the Water Heater
A CAUTION
Never use this water heater unless it is completely filled with J
water. To prevent damage to the tank, the tank must be filled J
with water. Water must flow from the hot water faucet
before turn ng ON gasto the water heater.
To fill the water heater with water:
• Close the water heater drain valve by turning the handle to
the right (clockwise). The drain valve is on the lower front of
the water heater.
• Open the cold water supply valve to the water heater.
NOTE: The cold water supply valve must be left open
when the water heater is in use.
• To insure complete filling of the tank, allow air to exit by
opening the nearest hot water faucet. Allow water to run
until a constant flow is obtained. This will let air out of the
water heater and the piping.
• Check all new water piping for leaks. Repair as needed.
Venting
A WARNING
VENT DAMPERS - Any vent damper, whether it is operated
thermally or otherwise must be removed if its useinhibitsprop-
er drafting ofthe water heater.
Thermally Operated Vent Dampers: Gas-fired water heaters
havingthermal efficiency in excessof 80% may produce a rela-
tively low flue gastemperature. Suchtemperatures may not be
high enough to properly open thermally operated vent
dampers. This would causespillageof flue gasesand may cause
carbon monoxide poisoning.
Vent dampers must bear evidence of certification ascomplying
with the latest edition of American National Standard ANSI
Z21.68 (ANSI Z21.66 & 67, respectively, cover electrically and
mechanically actuated vent dampers). Before installation of any
vent damper, consult your local SearsService Center or the gas
utility for further information.
AWARNING
To insure proper venting of this gas-fired water heater, the
correct vent pipe diameter must be utilized. Any additions or
deletions of other gas appliances on a common vent with this
water heater may.adversely affect the operation of the water
heater. Consult the local Sears Service Center or gasutility if
any such changesare planned.
For proper venting in certain installations, a larger diameter vent
pipe may be necessary. Due to great variances in installations,
unforeseeable by the manufacturer of the water heater, you mus
consult )'our gas company to aid you in determining the proper
venting for your water heater from the vent tables in the latest edi-
tion of the National Furl Gas Code ANSI Z223.l, aim referred to
as NFPA 54.
Check the venting system for signs of obstruction or deterioration
and replace if needed.
The combustion and ventilation air flow must not be obstructed.
f A WARNING
Obstructedor deterlo_s maypresenta serious
healthriskor asphyxiation.
• Place the draft hood legs in the receiving holes on the top of
the water heater. The legs will snap in the holes to give a
tight fit.
• Place the vent pipe over the draft hood. With the vent pipe in
position, drill a small hole through both the vent pipe and
draft hood. Secure them together with a sheet metal screw.

The water heater with draft hood installed must be properly
vented to a chimney which terminates outdoors. Never oper- I

adequate air supplyto avoidrisks of improper operation, explo-
sionor asphyx at on.
AWARNING J
The vent pipe from the water heater must be no less than the J
diameter of the draft hood outlet on the water heater, and
must slope upward to the chimney at least ¼ inch per linear
foot.
