DOMESTIC SIDE PIPING
BASIC DOMESTIC PIPING
Figure 12 shows typical domestic water piping for a Maxi-Therm. All components except the thermostat are
provided by the installer. The function of the components shown are as follows:
a) Thermostat (required) - This control is provided by Crown and must be installed in the location
indicated. It is imperative that the bulb of the thermostat is “bottomed out” in the control well. This
thermostat controls the temperature of the domestic water.
b) Shut-off valves (recommended) -Used to isolate the tank for servicing.
c) Backflow Preventer (required by some codes) - Use to prevent water from backing out of the Maxi-
Therm in the event that inlet water pressure drops.
d) Expansion Tank (required when a backflow preventer is used) - This expansion tank absorbs the
increased volume caused by heating water. If a backflow preventer is installed, this expansion tank is
required because the increased water volume will otherwise have no place to go and the T & P valve
will open.
Use an expansion tank designed for use on domestic water systems such as Watts DET series.
Consult the expansion tank manufacturer’s literature for the proper size expansion tank to use.
IMPORTANT
If an expansion tank is used, do not put any valves between the expansion tank and
Maxi-Therm inlet.
