CHAPTER 4 - BOILER PIPING
The expansion tank must be located as shown in
Fig. 14 on page 23,
when using a hydraulic separator
arrangement. Refer to the expansion tank manufacturer
for additional installation details.
Connect the expansion tank to an air separator only if
the air separator is located on the suction side (inlet)
of the system circulator. Always locate and install the
system fill connection at the same location as the
expansion tank connection to the system.
The expansion tank must be located directly on the
INSTINCT Combi return pipe, before the return check
valve. Incorrect expansion tank location will cause sys-
tem water to be lost through the pressure relief valve
and cause additional makeup water to be added to
the system. Eventual boiler heat exchanger failure can
result due to this excessive makeup water addition.
4.9.2 Diaphragm Expansion Tank
Always install an automatic air vent on top of the air
separator to remove residual air from the system.
4.9.3 Sizing Primary Piping
See Fig. 15 on page 26 through Fig. 17 on page
28 , for recommended piping arrangements based
on various applications. Size the piping and system
components required in the space heating system
using recognized design methods.
4.9.4 System Piping – Zone Circulators
Connect the INSTINCT Combi to the system piping as
shown in
Fig. 20 on page 32 when zoning with zone
circulators.
The installer must provide a separate circulator for each
zone of space heating.
4.9.5 System Piping – Zone Valves
Connect the INSTINCT Combi to the system piping as shown
in
Fig. 21 on page 33 when zoning with zone valves.
CAUTION
4.8.13 System Piping – Multiple Units Installation
Use a balanced manifold system as the primary /
secondary connection to the space heating piping.
For the space heating piping, refer to the applications
mentioned in this manual or use recognized design
methods.
4.8.14 Circulator
The INSTINCT Combi is supplied with a Boiler circulator
that provides circulation for central/space heating(CH)
and Domestic Hot Water (DHW) production.
4.9. INSTINCT Combi Boiler System Piping
It is recommended on all piping applications to
utilize the hydraulic separator arrangement 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
Chapter 19 on page 99
.
For other piping arrangements, 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.
4.9.1 Expansion Tank and Makeup Water
Ensure the expansion tank is properly sized for the
boiler volume:
• 3 gallons [12 L] for the INSTINCT Combi 155
• 4 gallons [15 L] for the INSTINCT Combi 199
the system water volume, and the system water
temperature.
Undersized expansion tanks will cause system wa-
ter to be lost through the pressure relief valve and
cause additional makeup water to be added to the
system. Eventual boiler heat exchanger failure can
result due to this excessive makeup water addition.
