CHAPTER 4 - BOILER PIPING
Connect the hydraulic separator using the sealing
washers provided.
Fit the manual air vents to the unused connections on
the side opposite the hydraulic separator.
199 Models
Ensure the washers are properly seated before tightening
the fittings.
The hydraulic separator is supplied is supplied with
connectors and union fittings to connect to 1¼”NPT
system pipework.
To fit the hydraulic separator:
Using an appropriate thread sealant fit the 1¼”
connecting nipple to the Instinct supply outlet then
connect the union fitting. Repeat this with the return
connection.
Orientate the union connections to ensure the sealing
faces align correctly with the hydraulic separator as
shown above.
Connect the hydraulic separator to the union fittings
using the sealing washers provided.
The system pipework must be aligned to connect with
the union fittings on the secondary circuit side of the
hydraulic separator. Using an appropriate thread sealant
connect the union fittings to the system pipework.
Connect the hydraulic separator using the sealing
washers provided.
Fit the manual air vents to the unused connections on
the side opposite the hydraulic separator.
CAUTION
4.8. INSTINCT Solo Boiler System Piping
4.8.1 Expansion Tank and Makeup Water
Ensure the expansion tank is properly sized for the
boiler volume:
• 2 gallons [8 L] for the INSTINCT Solo 110
• 3 gallons [12 L] for the INSTINCT Solo 155
• 4 gallons [15 L] for the INSTINCT Solo 199
the system water volume, and the system water temperature.
Undersized expansion tanks will cause system 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.
The expansion tank must be located as shown in Fig. 9
on page 17 , when using a hydraulic separator piping
arrangement or as per recognized design methods.
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.
4.8.2 Diaphragm Expansion Tank
Always install an automatic air vent on top of the air
separator to remove residual air from the system.
4.8.3 Closed-Type Expansion Tank
It is recommended to pitch any horizontal piping up-
wards toward the expansion tank 1 inch per 5 feet of
piping. Use 3/4” piping to the expansion tank to allow
air within the system to rise.
DO NOT install automatic air vents on a closed-
type expansion tank system. Air must remain in the
system and be returned to the expansion tank to
provide an air cushion. An automatic air vent would
cause air to be vented from the system resulting in a
water-logged expansion tank.
