* Note that production boiler PCBs are
factory pre-set to operate for boiler range
and output. When ordering Primary PCB
as a spare, an additional Boiler Chip Card
(BCC) MUST also be purchased for your
specific boiler range and output.
Check boiler serial letter code on data
plate to obtain correct BCC.
