THERMALEXPANSION

Water supply systems may, because of such events as high line pressure, frequent cut-offs, the effects of water hammer among others, have installed devices such as pressure reducing valves, check valves, back flow preventers, etc. to control these types of problems. When these devices are not equipped with an internal by-pass, and no other measures are taken, the devices cause the water system to be closed. As water is heated, it expands (thermal expansion) and closed systems do not allow for the expansion of heated water.

The water within the water heater tank expands as it is heated and increases the pressure of the water system. If the relieving point of the water heater’s temperature-pressure relief valve is reached, the valve will relieve the excess pressure. The temperature-pressure relief valve is not intended for the constant relief of thermal expansion. This is an unacceptable condition and must be corrected. It is recommended that any devices installed which could create a closed system have a by-pass and/or the system have an expansion tank or device to relieve the pressure built by thermal expansion in the water system. Expansion tanks are available for ordering through a local plumbing contractor. Contact the local water heater supplier or service agency for assistance in controlling these situations.

STRANGESOUNDS

Possible noises due to expansion and contraction of some metal parts during periods of heat-up and cool-down do not necessarily represent harmful or dangerous conditions.

OPERATIONAL CONDITIONS

SMELLY WATER

In each water heater there is installed at least one anode rod (see parts sections) for corrosion protection of the tank. Certain water conditions will cause a reaction between this rod and the water. The most common complaint associated with the anode rod is one of a “rotten egg smell” in the hot water. This odor is derived from hydrogen sulfide gas dissolved in the water. The smell is the result of four factors which must all be present for the odor to develop:

A.A concentration of sulfate in the supply water.

B.Little or no dissolved oxygen in the water.

C.A sulfate reducing bacteria which has accumulated within the water heater (this harmless bacteria is nontoxic to humans).

D.An excess of active hydrogen in the tank. This is caused by the corrosion protective action of the anode.

The anode rod in a new glass-lined water heater works rapidly to protect the tank. After a period of time the anode action slows and the odor may dissipate.

A smelly water condition (Rotten Egg Odor) in your Point of Use water heater can , in most cases, be resolved or reduced with the addition of sufficient amounts of chlorine to eliminate the bacterial growth inside the tank. This can be accomplished through the installation of a chlorine feeder to the system or the periodic flushing of the water heater with

bleach as needed. On systems where the odor is mild and does not occur too rapidly, a monthly flushing may be sufficient. In more severe cases, a system feeder would be more appropriate.

“AIR” IN HOT WATER FAUCETS

HYDROGEN GAS: Hydrogen gas can be produced in a hot water system that has not been used for a long period of time (generally two weeks or more). Hydrogen gas is extremely flammable and explosive. To prevent the possibility of injury under these conditions, we recommend the hot water faucet, located farthest away, be opened for several minutes before any electrical appliances which are connected to the hot water system are used (such as a dishwasher or washing machine). If hydrogen gas is present, there will probably be an unusual sound similar to air escaping through the pipe as the hot water faucet is opened. There must be no smoking or open flame near the faucet at the time it is open.

HIGHWATERTEMPERATURESHUTOFFSYSTEM

A non-adjustable high temperature limit control operates before steam temperatures are reached. The high limit is in the same area as the thermostat and must be reset manually when it operates. BECAUSE THE HIGH LIMIT OPERATES ONLY WHEN ABNORMALLY HIGH WATER TEMPERATURES ARE PRESENT, IT IS IMPORTANT THAT A QUALIFIED SERVICE AGENT BE CONTACTED TO DETERMINE THEREASONFOROPERATIONBEFORERESETTING.

•Turn off the heater electrical supply. Do not attempt to reset thermostat with power on.

•Remove the two screws securing the outer door and remove door.

•Fold back the insulation to expose the reset button opening.

•Reset the high limit by pushing in the red button marked “RESET”.

•Fold back the insulation so that it completely covers the thermostat and element.

•Replace the outer door.

•Turn “ON” electric power to the water heater.
