Undersized expansion tanks cause system water to be lost from the relief valve, causing make-up water to be
added. Eventual boiler failure can result due to excessive make-up water addition.
SUCH FAILURE IS NOT
COVERED BY WARRANTY.
2. The expansion tank must be located as shown in Part 4, Boiler Piping, or following recognized design methods.
See expansion tank manufacturer’s instructions for details.
3. Connect the expansion tank to the air separator only if the air separator is on the suction side of the circulator.
Always install the system fill connection at the same point as the expansion tank connection to the system.
4. Most chilled water systems are piped using a closed type expansion tank.
DO NOT install automatic air vents on closed type expansion tank systems. Air must remain in the system and
return to the tank to provide an air cushion. An automatic air vent would cause air to leave the system, resulting in
improper operation of the expansion tank.
DIAPHRAGM (OR BLADDER) EXPANSION TANK
Always install an automatic air vent on top of the air separator to remove residual air from the system.
E. CIRCULATORS
DO NOT install automatic air vents on closed type expansion tank systems. Air must remain in the system and
return to the tank to provide an air cushion. An automatic air vent would cause air to leave the system, resulting in
improper operation of the expansion tank.
DO NOT use the boiler circulator in any location other than the ones shown in this manual. The boiler circulator
location is selected to ensure adequate flow through the boiler. Failure to comply with this caution could result in
unreliable performance and nuisance shutdowns from insufficient flow.
Sizing Space Heat System Piping
1. See Piping Details in this manual, Section G. In all diagrams, the space heating system is isolated from the
boiler loop by the primary/secondary connection.
2. Size the piping and components in the space heating system using recognized design methods.
