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