DOMESTIC WATER PIPING

1. Thread the included 3 / " brass tee onto the pipe marked
4
COLD WATER.
2. Screw the
3 / " drain valve into the opposite end of the brass
4
tee.
3. Connect the cold water supply to the remaining port on the
brass tee.
4. Temporarily attach the top tee fitting (with o-ring face seal)
to the union nut on top of the tank. Test fit the piping near
the tee before soldering. Remove the tee before soldering
connections to avoid damage to the top o-ring seal or
plastic liner.
Note: Do not solder piping within 24 inches of the top tee
fitting while attached to the tank.
5. Make an 8-inch "heat trap" as shown in the diagram.
This will reduce standby losses from heat migrating up
the piping. Continue this line to the domestic hot water
system.
6. Install the included T&P relief valve on the top port of the
top tee connection. Plumb a blowdown tube to within 6
inches of a floor drain or as directed by plumbing code.
7. When all domestic water piping is complete, open the cold
water supply and allow some water to enter the tank. Look
and listen for signs of leaks and repair as necessary before
continuing.
Note: If installing on a city supply, ensure a dedicated
Thermal Expansion tank (Therm-X-Trol
used.

BOILER PIPING

1. Plumb the circulator or zone valve on the BOILER SUPPLY
line. If using a separate circulator, the pump flange
can be mounted directly to the threaded pipe marked
BOILER SUPPLY. Alternately, the circulator can be placed
anywhere on the boiler supply line.
2. Pipe the BOILER RETURN connection to the boiler return
line.
Be sure the return line is NOT
plumbed to the suction side of
any heating circulators. This may require moving the
heating circulator off the boiler tapping on packaged
boilers. Failure to do so will result in overheating and
tank damage when the heating system is in operation.
3. Install a weighted flow check on the boiler return line. This
is not necessary on systems utilizing a zone valve to control
the BoilerMate temperature.

4. After completing the boiler piping, slowly open the boiler fill
valve and pressurize the BoilerMate
and repair as necessary. Proceed to the appropriate wiring
section in this manual.
