Filling the Water Heater
A CAUTION
I
Never use thiswater heater unlessit is completely filled with [
water. To prevont damageto the tank, the tank must be filled I
with water. Water must flow from the hot water faucet
beforeturning ON" gasto tile water heater.
For proper venting in certain installations, a largerdiametervent
pipe may be necessary. Due to great variancesin installations,
unforeseeable by the manufacturer o f the waterheater, you must
consult your gascompany to aid you in determiningthe 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 valveis on the lowerfront of
the water heater.
• Open the cold water supply valveto 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.Repairas needed.

AWARNING
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 advarselya_rectthe operation of the water
heater. Consult the localSears Service Center or gas utility if
any suchchangesam planned.
Check the venting system for signs of obstruction or deteriora-
tion and replaceif needed.
The combustion and ventilationair flowmust not be obstructed.

• Place the drafthood legs in the receiving holes on the top of
the water heater. The legswill snap in the holes to give a tight
fit.
• Place the vent pipe over the drafthood. With the vent pipe in
position, drill a small hole through both the vent pipe and
drafthood. Secure them together with a sheet metal screw.
