PRODUCT IDENTIFICATION
b
If these plates or any other means of clearly identifying the product are defaced, removed or lost, proper installa-
tion and servicing may be rendered difficult.
-
Serial number plate
This is located on the boiler body and speci-
fies the serial number, model, furnace power
and maximum operating pressure.
-
Data plate
This lists the technical specifications and per-
formance of the product.
It comes inside the documentation envelope.
On completion 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
