tions and warnings in the manual may result

DESCRIPTION

When water is heated, it expands. Provision must be

made for this expansion in a closed hot water heating

system. The Bell & Gossett Series HFT pre-charged

diaphragm tank stores the expanded hot water and

returns air-free water to the system when the

temperature drops.

OPERATIONAL LIMITS

Maximum Operating Pressure: 100 PSI.

Maximum Operating Temperature: 240ºF.

under pressure, may over time corrode,

weaken and burst or explode, causing

serious or fatal personal injury, leaking or

ﬂooding and/or property damage. To minimize risk, a

licensed professional must install and periodically

inspect and service the Product. A drip pan connected

to an adequate drain must be installed if leaking or

ﬂooding could cause property damage. Do not locate in

an area where leaking could cause property damage.
