Maytag HRP11275P, HRN11250P, HRP31250P T & P Valve and Pipe Insulation, See for mixing valve usage

addition to using the lowest possible temperature setting that satisfies your hot water needs, a means such as a *mixing valve, shall be used at the hot water taps used by these people or at the water heater. Mixing valves are available at plumbing supply or hardware stores, see Figure 8 on page 9 and Figure 21 below. Valves for reducing point of use temperature by mixing cold and hot water are also available. Consult Maytag Customer Service (1-800-788-8899). Follow manufacturer’s instructions for installation of the valves. Before changing the factory setting on the thermostat, read the Temperature Regulation section in this manual.

See Figure 21 for mixing valve usage.

FIGURE21.

This water heater shall not be connected to any heating systems or component(s) used with a non-potable water heating appliance.

If a water heater installed in a closed water supply system; such as one having a back-flow preventer, check valve, water meter with a check valve, etc. . . in the cold water supply; means shall be provided to control thermal expansion. Contact the local utility or call Maytag Customer Service Center at 1-800-788-8899 for an authorized installer on how to control this situation.

Figure 22 shows the typical attachment of the water piping to the water heater. The water heater is equipped with 3/4” NPT water connections for 40,000 Btuh models and 1 inch water connections for 70,000 and 75,000 Btuh models.

NOTE: If using copper tubing, solder tubing to an adapter before attaching the adapter to the cold water inlet connection. Do not solder the cold water supply line directly to the cold water inlet. 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”. 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”. 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 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.

T & P Valve and Pipe Insulation

Remove insulation for T & P valve and pipe connections from carton.

Fit pipe insulation over the incoming cold water line and the hot water line. Make sure that the insulation is against the top cover of the heater.

Fit T & P valve insulation over valve. Make sure that the insulation does not interfere with the lever of the T & P valve.
