Bradford White TW-55X-78B-3X - Manual (Page 3)

Remove all components from the
package and check that all required
components are included. The required
components are: mixing device, cold
water tee, flexible metal connector and
thermostrip (see Figure 1).
This kit may have two flexible
connectors provided for water heaters
with top water course connections at 8
inch and 11 inch spacing. Use the
appropriate flexible metal connector.
The mixing device, cold water tee, flexible metal connector and thermostrip are integral parts of the
water heater. This system improves hot water deliverability and must be installed. The integrated
appliance is designed for a maximum working pressure of 150 p.s.i. (1034 kPa). Refer to the
“Water Connections” section of the installation and operation instruction manual supplied with the
water heater for additional instructions.
WATER CONNECTIONS
The mixing device is equipped with a ½” NPT alternate hot water
outlet that draws unmixed very hot water from the tank. This outlet
should be used if unmixed very hot water is needed at specific
fixtures (laundry, dishwasher, etc…). It is also equipped with a ½”
NPT optional recirculation inlet that must be utilized in conjunction
with a check valve if a recirculation loop is used (see Figure 2).
WARNING
If recirculation loop water is returned
to the water heater at any location
other than the optional recirculation
inlet, unmixed very hot hot water is
exposed to the recirculation loop.
Do not return recirculation loop to
any other location other than “R”
inlet of the mixing device.
