The products are identied by:
Serial number plate
This is located on the boiler body and species the serial num-
ber, model, and furnace power.
Data plate
This lists the technical specications and performance of the
product. It comes inside the documentation envelope. On com-
pletion of the installation you MUST apply it in a clearly visible
position at the top of one of the side panels. If you damage
or lose this label, order a replacement immediately from
