Filling the Water Heater

A CAUTION

J

Never use this water heater unless it is completely filled with J water. To prevent damage to the tank, the tank must be fiUed J with water. Water must flow from the hot water faucet

before turn ng ON gas to the water heater.

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

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 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 damper, whether it is operated thermally or otherwise must be removed if its use inhibits prop- er drafting of the water heater.

Thermally Operated Vent Dampers: Gas-fired water heaters having thermal 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 cause spillage of flue gasesand may cause carbon monoxide poisoning,

Vent dampers must bear evidence of certification as complying with the latest edition of 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 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 other gas appliances on a common vent with this water heater may adversely affect the operation of the water heater. Consult the local Sears Service Center or gas utility if any such changes are planned.

Check the venting system for signs of obstruction or deteriora- tion and replace if needed.

The combustion and ventilation air flow must not be obstructed.

AWARNINGJ

Obstructedor deterioratedventsystemsmay presenta serious

healthHskor asphyxat on.

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.

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.

AWARNINGJ

The water heater with draft hood installed must be properly J vented to a chimney which terminates outdoors. Never oper- J ate the water heater unlessit is vented to the outdoors and has J adequate air supplyto avoid Hsksof improper operation, explo- sionor asphyxiation.

AWARNING

The vent pipe from the water heater must be no lessthan the diameter of the draft hood outlet on the water heater, and

must slope upward to the chimney at least ¼ inch per linear foot.
