Temperature-Pressure Relief Valve

Maytag HXN4975S manual Temperature-Pressure Relief Valve

Toxic chemicals, such as those used for boiler treatment shall not be introduced into this system.

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 to relieve the pressure built by thermal expansion in the water system. Refer to the Thermal Expansion section under Troubleshooting Guide or contact local plumbing authority or call Maytag

can be accomplished by insulating the hot water lines from the water heater.

NOTE: To protect against untimely corrosion of hot and cold water fittings, it is strongly recommended that di-electric unions or couplings be installed on this water heater when connected to copper pipe.

Figure 16 shows the typical attachment of the water piping to the water heater. The water heater is equipped with 1” NPT water connections for 75 gallon models.

NOTE: If using copper tubing, solder tubing to an adapter before attaching the adapter to the water connections. Do not solder the water lines directly to the water connections on the tank. It will harm the dip tube and damage the tank.

•Look at the top cover of the water heater. The water outlet is marked “HOT”. Put two or three turns of teflon tape around the exposed end of the 1” NPT threaded nipple. Connect the hot water pipe to the hot water outlet on the water heater.

•Look at the top of the water heater. The cold water inlet is marked “COLD”. Put two or three turns of teflon tape around the exposed end of the 1” NPT threaded nipple. Connect the cold water pipe to the cold water inlet of the water heater.

NOTE: This water heater is super insulated to minimize heat loss from the tank. Further reduction in heat loss
