_E,CAUTION ]
Never usethiswater h_ completelyfilledwith
water To prevontdamageto the tenk, the tank mustbefilledI
with water. Water must flow from the hot water faucet
beforetuming"ON" gastothe 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 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 our of the
water heater and the piping.
Check allnew water piping for leaks. Repair asneeded.

A,WARNING
VENT DAMPERS - Any vent damper, whether it is operated
thermally or otherwise must be removed if its useinhibitsprep-
er drafting ofthe water heater,
Thermally Operated Vent Dampers: Gas-fired water heaters
havingthermal efficiency in excessof 80% may produce a rela.
t_ely lowIlue 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 evidenceof certification as complying
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, consult your localSears Service 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 gasappliances on a common vent with this
water heater may adversely affect the operation of the water
heater. Consult the local SearsService Center or gas utility if
any suchchanges are 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.
