CHAPTER 4 - BOILER PIPING
4.5. Additional Limit Control
If a separate Low Water Cut O (LWCO) is required by
the local jurisdiction or when the boiler is installed
above the system piping, the following guidelines
must be followed:
• The LWCO must be designed for water installations,
electrode probe-type is recommended.
• The LWCO must be installed in a tee connection on
the boiler supply piping above the boiler.
• Wiring of the LWCO to the INSTINCT is done directly
onto the low voltage terminal strip. Reference Fig.
30 on page 46 for available external limit (manual
or auto reset) terminals.
If the installation is to comply with ASME or Canadian
requirements, an additional high temperature limit
may be required. Consult local code requirements to
determine compliance. The limit should be installed as
follows:
• Install the limit in the boiler supply piping between
the boiler and any isolation valve.
• Consult heat exchanger for maximum temperature
set point.
• For wiring of the limit, reference Fig. 30 on page
46. Wire the limit to the manual reset terminals
on the low voltage terminal strip. An open manual
reset limit will require a manual reset of the control.
4.6. Backflow Preventer
• Use a backow preventer valve in the make-up wa-
ter supply to the unit as required by local codes.
4.7. INSTINCT Solo Boiler System Piping
• It is recommended on all piping applica-
tions to utilize a primary/secondary piping
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 101.
For other piping arrangements, contact
Triangle Tube Technical Support or con-
sult other approved/recognized design ar-
rangements.
• On piping applications utilizing a single zone
or other recognized piping design arrange-
ments, it is recommended that the installer
uses flow/check valves with weighted seats at
or near the INSTINCT Solo to prevent gravity
circulation.
