Filling the Water Heater
&CAUTION
I
Never usethis water heater unlessit ms completelyfilled w_l
water. To preventdamageto the tank, the tank mustbe filled I
with water. Water must flow from the hot water faucet I
I beforetorn 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
_WARNING
VENT DAMPERS- Any vent damper,whether it is operated
thermallyor otherwise mustbe removedif itsuseinhibits prop-
er drafting of thewater heator,
Thermally Operated Vent Dampers:Gas-firedwater heaters
havingthermal efEciency in eacessof 80% may producea rela-
low fluegastemperature.Suchtemperaturesmay not be
high enough to properly open thermally operated vent
dampen. Thiswouldcausespillage of flue gases andmay cause
carbonmonoxidepoisoning.
dampersmustbear evidence ofcertiEcntion as complying
with the latest edition of American National StandardANSI
Z21.68 (ANSI 7.21.66& 67, respectively, coverelectricallyand

vent damper,consult y ourlocalSea_ ServiceCenter or the gas
utilityfor further information.
AWARNING
To insure proper venting of this gas-fired water heater, the
correctvent pipediameter mustbe utilized.Any additionsor
deletions of other gasappliances on a common vent with this
water heater may adverselyaffectthe operation of the water
heater,Consultthe localSearsServiceCenter or gasutility if
anysuchchanges are 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 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.
Check the venting system for signs of obstruction or deterioration
and replace if needed.
The combustion and ventilation air flow must not be obstructed.
AWARNING . I
Obstructed or deteri,o_ted ventsystems maypresenta senous
healthrisk or 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.
