Filling the Water Heater
_, CAUTION I
Never use this water heater unlessit is completely filled with
water. To prevent damageto the tank, the tank must be filled I
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,
unforeseeableby 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 edi-
tion of the National Fuel Gas Code ANSI Z223.1, alsoreferred 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 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
thermally or otherwisemust be removed if itsuseinhibitsprop-
er draftingof the water heater.
Thermally Operated Vent Dampers: Gas-fired water heaters
havingthermal efficiencyin excessof 80% may producea rela-
tivelylowflue gastemperature. Suchtemperatures may not be
high enough to properly open thermally operated vent
dampers. Thiswould causespillage of fiue gases and may cause
carbon monoxide poisoning.
Vent dampers must bear evidenceof certificationas complying
with the latest edition of American National Standard ANSI
Z21.68 (ANSi Z21.66 & 67, respectively, c over electricallyand
mechanicallyactuatedvent dampers).Beforeinstallationof any
vent damper, consultyour localSearsServiceCenter or the gas
utilityfor further information.
•_ WARNING
To insure proper venting of this gas-fired water heater, the
correct vent pipe diameter must be utilized. Any additionsor
deletions of other gasapplianceson a common vent with this
water heater may adverselyaffectthe operation of the water
heater. Consult the localSears Service Center or gasutility if
any suchchangesare planned.
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
Obstructedor deterioratedvent systemsmay presenta seriousI
healthriskor asphyxiation. [
• Place the dra_ 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 ;crew.
