the Water Heater
Property Damage Hazard
- Avoid water heater damage.
- Fill tank with water before operating.
Never use this water heater unless it is completely full of water.
To prevent damage to the tank, the tank must be filled 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 water piping and connections for leaks. Repair as
needed.
VENT DAMPERS - Any vent damper, whether 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 the flue gases and may
cause carbon monoxide poisoning.
Vent dampers must bear evidence of certification as complying
with the current edition of the American National Standard
ANSI Z21.68 (ANSI Z21.66 & 67, respectively, cover electrically
and mechanically actuated vent dampers). Before installation
of any vent damper, consult your local Sears Service Center or
the local gas supplier for further information.
Breathing Hazard = Carbon Monoxide Gas
• Vent dampers must be certified
in accordance with ANSI Z21.68.
• Vent damper must permit proper
drafting of water heater.

rated vent system to avoid

Breathing carbon monoxide can cause brain damage or
death. Always read and understand instruction manual.
To insure proper venting of this gas-fired water heater, the
correct vent pipe diameter must be utilized. Any additions or
deletions of other gas appliances on a common vent with this
water heater may adversely affect the operation of the water
heater. Consult your gas supplier if any such changes are
planned. For replacement heater installations where using pre-
existing venting, venting must be inspected for obstructions and
if deterioration is present, venting must be replaced.
For proper venting in certain installations, a larger diameter vent
pipe may be necessary. Consult your local Sears Service Center
or gas supplier to aid you in determining the proper venting for
your water heater from the vent tables in the current edition of
the National Fuel Gas Code ANSI Z223.1/NFPA 54.
Periodically check the venting system for signs of obstruction or
deterioration and replace if needed.
The combustion and ventilation air flow must not be obstructed.
The water heater with draft hood installed must be connected
to a chimney or listed vent pipe system, which terminates to the
outdoors. Never operate the water heater unless it is vented
to the outdoors and has adequate air supply to avoid risks of
improper operation, explosion or asphyxiation.
For proper draft hood attachment, the draft hood legs may
be angled slightly inward.
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. Secure two legs to top with sheet metal screws.
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.
See Figure 18.
Obstructed or deteriorated vent systems may present serious
health risk or asphyxiation.
