Sears 153.336431 Filling the Water Heater, Vent Pipeinstallation, Tion, explosion or asphyxiation

WARNING

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

CAUTION

Never use this water beater unless it is completely filled

with water. To prevent damage to the tank, the tank must be fiUed 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:

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 wben the water heater is _n use.

•l-o 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.

4. Check all new water piping for leaks. Repair as needed.

Venting

WARNING

VENT DAMPERS - Any vent damper, whether it is operated thermaffy 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 ofcertlfication as com- plying with the latest edition of the American Natlonal Standard ANSI Z21.68 (ANSI Z21.66 & 67, respectively,

cover electrically and mechanically actuated vent dampers).

Before installatmn of any vent damper, consult the local Sears Service Center or gas utility for further information.

WARNING

i To insure proper venting of this gas-fired water heater, the correct vent p,"pediameter must be utilized. Any additions or Jeletions of otl_er gas appliances on a common _ventwith this water heater may adver-selyaffect the operation of the water heater. Consult the local Sears Service Center or gas utility if any such 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 properWenting 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 signs of obstruction or deterio- ration and replace if needed.

The combustion and ventilation air flow must not be obstructed.

WARNING

The water beater with draft hood installed must be Connect-

ed to a chimney which terminates to the outdoors. Never operate the water heater unless it is vented to the outdoors and has adequate air supply to avoid risksof improper opera-

tion, explosion or asphyxiation.

WARNING

WARNING,

The vent p!pefrom the water_heater.must he no lessthan the I diameter of the draft hood outlet on the water heater, and must i

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

All vent gases must be completely vented to the outdoors of the structure (dwelling). Install only the draft hood pro- vided with the new water heater and no other draft hood.

Vent pipes must be secured at each joint with sheet metal screws.

VENT PIPEINSTALLATION

There must be a minimum of 6 inch clearance between single wall vent pipe and any combustible material. Fill and seal any clearance between single wall vent pipe and combustible material with mortar mix, cement, or other noncombustible substance. For other than single wall, fol- low vent pipe manufacturer's clearance specifications. To insure a"tight fit of the vent pipe in a brick chimney, seal around the vent pipe with mortar mix cement.

I	WARNING
J Failure to have required clearances between vent piping		J
Iand combustible material will result in a fire hazard.
