DESCRIPTION
Many local codes require back fl ow preventers. Since this
seals off the system, an expansion tank is required or
the relief valve will discharge on every heating cycle. The
thermal expansion tanks eliminate this wasteful, costly,
and dangerous practice. The thermal expansion tank is
designed to be used with water temperatures to 140° F
(60° C). DO NOT USE A STANDARD TANK. The sizing chart
will allow you to choose the correct size expansion tank
for your application. When water is heated, it expands.
Provision must be made for this expansion in a closed hot
water heating system. The Bell & Gossett Series PT
pre-charged diaphragm tank stores the expanded hot
water and returns air-free water to the system when the
temperature drops.
