CHAPTER 4 - BOILER PIPING
4.7.11 System Piping – Special Application
If the boiler is used in conjunction with a chilled water/
medium system, the boiler and chiller must be piped in
parallel. Install ow/check valves to prevent the chilled
medium from entering the boiler.
If the boiler is used to supply hot water to the heating
coils of an air handler where they may be exposed to
chilled air circulation, install ow/check valves or other
automatic devices to prevent gravity circulation of the
boiler water during cooling cycles.
4.7.12 System Piping – Multiple Units Installation
Use a balanced manifold system as the primary / sec-
ondary connection to the space heating piping.
For the space heating piping, refer to the applications
mentioned in this manual or use recognized design
methods.
4.8. INSTINCT Combi Boiler System Piping
It is recommended on all piping applications
to utilize a primary/secondary piping arrange-
ment as a means to provide freeze protection of
the boiler, which is an integral function of the
boiler control. Maintain at least the minimum
boiler flow rate shown in the Graphs of Chap-
ter 19 on page 101. For other piping arrange-
ments, contact Triangle Tube Technical Support
or consult other approved/recognized design
arrangements.
On piping applications utilizing a single zone or
other recognized piping design arrangements,
it is recommended that the installer uses flow/
check valves with weighted seats at or near the
INSTINCT Combi to prevent gravity circulation.
