tenance and service must be provided. Water lines and the

storage tank should be protected from freezing tempera-

tures. Do not install the storage tank in outdoor unprotected

areas. It is desirable to have a floor drain nearby to permit

easy draining if necessary.

A circulator pump is not supplied. Use only a bronze body

model rated for 110/120 volts, 60Hz. Install in accordance

with the pump manufacturer’s instructions using standard

plumbing practices.

The main parts and features of your storage booster tank

are identified in Figure 1. Install plumbing according to

Figure 2 for single storage tank and according to Figure 3

for multiple storage tank systems.

1. Ensure the storage tank is level before starting installa-

tion.

2. Install circulation loop as shown using 19mm (¾ in.)

copper pipe.

3. Install the cold water supply piping into a tee between

the circulator discharge and the boiler coil inlet.

4. Connect the boiler supply line to the combination return

and drain valve.

5. Connect hot water supply to top tank fitting.

6. Install 19mm (¾ in.), 150 psi Temperature and Pressure

Relief Valve into the tank as shown.

7. A check valve may be installed between the cold water

tee connection and the circulator. This will force the cold

water through the coil first.

NOTE: The check valve can often be noisy and cause

reduced supply pressures. For multiple storage tank sys-

Do not apply heat directly to tank fittings when making

sweat connections. They contain non-metallic material.

The water heating source piping and components con-

nected to the tank must be suitable for potable water use.

TOXIC chemicals such as used for boiler treatment must

not be introduced into the tank.
