Maytag HRN11240P Water Heater User Manual

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.
FIGURE 22.
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.
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.
FIGURE 21.
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.
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.
