Filling the Water Heater

CAUTION

Never use this water heater unlessit is completely filled

with 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" gasto the water heater. To fill the water heater with water:

1.Close the water heater drain valve by turning the han- dle to the right (clockwise). The drain valve is on the lower front of the water heater.

2.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 rl use.

3.To insure complete fillin_ of the tank, allow air to exit by opening the nearest hot water faucet. Allow water to run unti/a constantflow is obtained. This will let air out of the water heater and the piping.

4.Check all new water piping for leaks. Repairas needed.

Venting

WARNING

VENT DAMPERS- Any vent damper,whether it is operated thermally or otherwisemust he removedif its useinhlbits proper drafting of the water heater.

Thermally OperatedVent Dampers:Gas-firedwater heaters having thermal efficiencyin excessof 80% may producea relatively low flue gastemperature.SuchtemperaturesmaX nut be high enoughto properly open thermally operated v_nt dampers. Thlswould causespillageof flue gasesand may causecarbon monoxidepoisoning.

Vent dampersmust bear evidenceof-certificati0n as com- plying with the latest edition of the American National

Standard ANSI Z21.68 (ANSI Z21.66 & 67, respectively, cover electricallyand mechanically actuatedvent dampers).

Before installation of any vent damper, consult the local SearsService Centeror gasutility for further information.

WARNING

To insure proper ventingof this gas-firedwater heater,the correctvent p}_oediametermustbe utilized.Any additionsor deletionsof otEergasapplianceson a commonventwith this waterheater may adverselyaffect the operationof the water heater.Consultthe localSearsService(_enteror gasutility if anysuch changesare 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 edition of the National Fuel

Gas Code ANSI Z223.1, also referred to as NFPA 54.

Check the venting system for signsof obstruction or deterio- ration and replace if needed.

The combustion and ventilation air flow must not be obstructed.

WARNING

1.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.

2.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.
