GSW G65 General Housekeeping, Temperature And Pressure Relief Valve, Water Temperature Regulation

GENERAL HOUSEKEEPING

As a precaution against fire, and to maintain an adequate flow of combustion air to the heater:

- Keep the appliance area clear and free from com- bustible material, gasoline and other flammable vapours and liquids.

-Keep any ventilation and combustion air openings unobstructed.

-do not pile cartons, papers or combustible materials on top or around the heater. Maintain clearances to combustible construction unobstructed.

the tank cools sufficiently (approximately 120oF) the switch will close. This will re-establish the electrical circuit and permit the pilot to function through E.C.O. If recycling of the E.C.O. occurs, it indicates that a problem exists in the heater or installation which must be corrected.

The non-recycling E.C.O. switch will open when water temper- ature exceeds fixed cutoff temperature. It will not close circuit again when the water temperature cools. When this contact opens, it indicates that a problem exists in the heater which must be corrected before a new control is used in the water heater. If single cycle energy cutoff switch opens contact, the control must be replaced.

For gas control replacement, contact your local gas utility, or a qualified service person. The replacement control must be an identical model to the control which has been removed.

TEMPERATURE AND

PRESSURE RELIEF VALVE

The temperature and pressure relief valve (T&P valve) is a part of the safety equipment on the water heater. In order to keep the T&P valve functioning properly, operate the valve at least once a year by lifting the manual lever until water dis- charges from the overflow pipe.

CAUTION: The water flowing from the valve will be HOT. Keep hands and feet away from the stream of water. Take care that discharging water does not damage any flooring, carpeting or other parts of the building which may be damaged by water.

WATER TEMPERATURE REGULATION

The thermostat is adjusted to its lowest temperature position when shipped from the factory. The temperature of the water can be selected by setting of the temperature dial on the front of the gas control. The normal setting corresponds to approx- imately 130oF.

GAS CONTROL

The gas control is equipped with an energy cutoff switch, E.C.O., which functions as a high limit safety switch. When the water temperature exceeds the fixed cutout temperature, the switch will cycle open. This will interrupt the pilot valve cir- cuit and stop all gas flow through the control.

Two types of E.C.O. limits are manufactured:

1.Recycling

2.Non recycling.

The recycling E.C.O. switch will open when water temperature exceeds fixed cutoff temperature. When the temperature in

CAUTION: Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and dangerous operation.

TEMPERATURE

Set temperature as low as possible to provide an adequate supply of hot water. This will reduce heat loss and extend the life of the glass lining. Every “notch” on the dial of the gas con- trol corresponds to approximately a 10o increment in water temperature.

HIGHER SETTING INCREASES

THE RISK OF SCALD INJURY

In households with children or invalids and elderly, select a lower temperature setting. To reduce the risk of scalding, valves for reducing point of use temperature by mixing cold and hot water are available. Consult a licensed plumber or the local plumbing authority.

EXPOSURE TO WATER

IMPORTANT

Should the water heater be subjected to flooding, fire or other unusual condition, turn off gas at the manual gas shut-off valve and water at the inlet valve to the heater. Do not put the heater in operation until a qualified gas technician has inspected and replaced any part of the gas control system that has been underwater.

TAMPERING

Tampering with the thermostat, gas valve, igniter control or temperature and pressure relief valve is DANGEROUS and voids all warranties. Only qualified personnel should service these components.
