NOTE

IBC VFC Series boilers

have been designed to take

advantages of the many

benefits of primary/secondary

piping. These models have a

software routine that utilizes

the boiler pump contacts on

start-up in order to prove

flow. The sketch below details

a wiring modification that

must be made when using

parallel pumping with IBC

VFC model Boilers.

Mechanical Drawing #3, immediately below,

is only applicable to the IBC model SL 20-115

Connect Yellow and

White Primary Pump

wires to the bottom

two terminals on the

Green Terminal Strip

On a VFC Model boiler, locate the

Yellow and White pair of wires in the

wiring box behind the IBC Control.

Connect the Yellow wire to the “P/V

Power L” terminal second from the

bottom on the Green terminal plug.

Connect the White wire to the bottom

terminal labelled “P/V Power N”. This

will satisfy the boiler’s flow proving

routine when either zone starts up.
