Filling the Water Heater
A CAUTION
Never use this water heater unless it is completeiy (iiied with
water. To prevent damj^ to the tank, the tank must be fiiied
with water. Water must flow from the hot water faucet
before turning “ON” gas to 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
AWARNING
VENT DAMPERS ■ Any vent clamper, whether It is operated
thermally or otherwise must be remcmd if its use inhibte prop­
er drafong of the water heater.
Thermally Operated Vent Dampers: Gas-flred water heaters
having thermai efficiency in excess of 80% may produce a rela­
tively low flue gas temperature. Such temperatures may not be
high enough to properly open thermally operated vent
dampers. This would cmise spill^ of flue ga^ and may cause
carbon monoxide poisoning.
>font dampers must bear evidence pf certification as complying
with the latest edition of American National Standard ANSI
Z2I.68 (ANSI Z2I.66 & 67, respectively, cover electrically and
mechanically actuated vent dampers). Before installation of any
vent damper, conmit your local Sears 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 c^er gas appliances on a common vent with this
water heater m^ adversely affect the operation of the water
heater. Consult the local Sears Service Center or gas utility if
any such changes 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 edi­
tion 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
Obstructed or deteriorated vent systems may present a serious
health risk or asphyxiation.
Place the draft hood legs in the receiving holes on the rop 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.

VENT TO OUTDOORS
OR CHIMNEY
AWARNING
The water heater with draft hood installed must be properly
vented to a chimney which terminates outdoors. Never imper­
ate thè water heater unless it ts vented to the outdoors and has
adequate air supply to avoid risks of improper operation, explo­
sion or asphyxiation.
AWARNING
The vent pipe from the water heater must be no less than the
diameter of the draft hood outlet on the water heater, and
must slope upward to the chimney at least 'A inch per linear
foot
