Filling the Water Heater
A CAUTION J
Never use this water heater unlessit is completely filled with J
water. To prevent damage to the tank, the tank must befiUed J
with water. Water must flow from the hot water faucet
before turn ng ON gasto the water heater.
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 must
consult your gas company to aid you in determining the proper
venting for your water heater from the vent tables in the latest
edition of the National Fuel Gas Code ANSI Z223.1, also
referred to as NFPA 54.
To fill the water heater with water:
• Close the water heater drain valve by turning the handle to
the right (clockwise). The drain valve ison 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
AWARNING
VENT DAMPERS - Any vent damper, whether it is operated
thermally or otherwise must be removed ifitsuseinhibitsprop-
er drafting ofthe water heater.
Thermally Operated Vent Dampers: Gas-fired water heaters
havingthermal efficiency inexcessof 80% may produce a rela.
tivelylowflue gastemperature. Suchtemperatures may not be
high enough to properly open thermally operated vent
dampers. This would causespillageofflue gasesand may cause
carbonmonoxide 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 installationof any
vent damper, consultyour local SearsService Center or the gas
utilityfor 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 gasappliances on a common vent with this
water heater may adversely affect the operation of the water
heater. Consult the local Sears Service Center or gas utility if
any suchchangesare planned.
Check the venting system for signs of obstruction or deteriora-
tion and replace if needed.
The combustion and ventilation air flow must not be obstructed.

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.

AWARNING J
The water heater with draft hood installed must be properly J
vented to a chimney which terminates outdoors. Never oper- J
ate the water heater unlessit isvented to the outdoors and hasJ
adequate air supplyto avoid Hsksof improper operation, explo-
sionor asphyxiation.
AWARNING
The vent pipe from the water heater must be no lessthan the
diameter of the draft hood outlet on the water heater, and
must slope upward to the chimney at least ¼inch per linear
foot.
