the temperature-pressure relief valve, and the discharge pipe.

•Shall terminate at an adequate drain.

•Shall not have any valve between the relief valve and tank.

The temperature-pressure relief valve must be manually operated at least once a year. Caution should be taken to ensure that

(1)no one is in front of or around the outlet of the temperature- pressure relief valve discharge line, and (2) the water manually discharged will not cause any bodily injury or property damage because the water may be extremely hot.

If after manually operating the valve, it fails to completely reset and continues to release water, immediately close the cold water inlet to the water heater, follow the draining instructions, and replace the temperature-pressure relief valve with a new one.

Filling the Water Heater

•Check all water piping and connections for leaks. Repair as needed.

Venting

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-ﬁ red water heaters having thermal efﬁ ciency in excess of 80% may produce a relatively low ﬂ ue gas temperature. Such temperatures may not be high enough to properly open thermally operated vent dampers. This would cause spillage of the ﬂ ue gases and may cause carbon monoxide poisoning.

Vent dampers must bear evidence of certiﬁ cation 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.

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 ﬂ ow from the hot water faucet before turning “ON” gas to the water heater.

To ﬁ ll 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 ensure complete ﬁ lling of the tank, allow air to exit by opening the nearest hot water faucet. Allow water to run until a constant ﬂ ow is obtained. This will let air out of the water heater and the piping.

To ensure proper venting of this gas-ﬁ red 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.
