Identification

Novella boilers are identified by a product
name plate giving the boiler's serial number,
model and main technical and performance
data.
b
It is essential to specify the correct
model of boiler when ordering spare
parts or requesting technical assistance.
If the name plate or any other means of
clearly identifying the product is defa-
ced, removed or lost, proper installation
and servicing may be rendered difficult.
