INSTALLER: PLEASE LEAVE THIS MANUAL FOR THE OWNER’S USE.

WARNING: Explosion or Rupture Hazard.

A relief valve must be installed to prevent

pressure in excess of local code requirement

or maximum working pressure

designated in the Product Manual, whichever is less.

Do not expose Product to freezing temperatures or

temperatures in excess of 140°F. Do not adjust the

pre-charge or re-charge this Product except for any

adjustments at the time of the initial installation,

especially if Product is corroded, damaged or with

diminished integrity. Adjustments to pre-charge must

be done at ambient temperature only. Failure to

properly size the Product or follow these instructions

may result in excessive strain on the system and may

lead to Product failure, serious or fatal personal injury,

leakage, and/or property damage.

WARNING: Read carefully the product

installation, operating and maintenance

instructions. Failure to follow the instruc-

tions and warnings in the manual may result

in serious or fatal injury and/or property damage, and

will void the product warranty. This product must be

installed by a qualiﬁ ed professional. Follow all

applicable local and state codes and regulations, in the

absence of such codes, follow the current editions of

the National Plumbing Code and National Electric

Code, as applicable.

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.
