Filling the Water Heater
_ CAUTION
Never usethis water heater unless it is completelyfilledwith
water. To prevent damageto the tank, the tank must be filled
with water. Water must flow from the hot water faucet
before turning "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 t_t'bntof
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
• 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
ti_:ht 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.

AWARNING
VENT DAMPERS - Any vent damper, whet'her it is
operated thermally or otherwise must be removed if its
use inhibits proper drafting of the water heater.
Thermally Operated Vent Dampers: Gas-fired water
heaters having thermal efficiency in excess of 80% may
produce a relatively low flue gas temperature. Such
temperatures may not be high enough to properly open
thermally operated vent dampers. This would cause
spillage of flue gases and may cause carbon monoxide
poisoning.
Vent dampers must bear evidence of certification as
complying with the latest edition of thh American
National Standard ANSI Z21.68 (ANSI Z21.66 & 67,
respectively, cover electrically and mechanically actuat-
ed vent dampers). Before installation of any vent
damper, consult the local Sears Service Center or gas
utility for further information.
AWAIRNING
To insure proper venting of this gas-firedwater beater, the
correctvent pipe diameter mustbe utilized.Any additions or
deletionsof other gasappliances on a common ventwith this
water heater may adversely affectthe operation ofthe water
heater.Consultthe localSearsServiceCenter or gasutilityif
anysuchchanges are 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.

All vent gases must be completely vented to the outdoors of the
structure (dwelling). Iustallonly the draft hood provided with
the new water heater and no other draft hood.
Vent pipes must be secured at each joint with sheet metal screws.
The water heater must be connected to a roof jack: The vent
pipe from the water heater to the roof jack mustbe no less than
the diameter of the draft hood outlet (rain. 3 ) on the water
heater.
This water heater may be installed with single wall or Type B
vent pipe connection to the draft hood and the following U.L.
listed roof jacks not furnished.

There must be a minimum clearance of 12" between the top of
the draft hood and the top of the enclosure.
The draft hood and combustion air inlet to the water heater
must be in the same atmospheric pressure zone. Do not separate
by a wall, shelf, ceiling, partition, or any other means.
A'WARNING ]
F.ai!ure to have required clearances between vent /
piping and combustible material wdl result m a fire|
hazard. |
AWARNING
Be sure vent pipe is properly connected to prevent
escape of dangerous flue gaseswhich could causedeadly
asphyxiation.
