RIVA FP SERVICE MANUAL – REV A 3
1 The Technical Manual
The aim of this manual is to provide technical
assistance operators with all the information
necessary to facilitate maintenance of Biasi
products.
To use this manual in the best possible way
and to find the information in it quickly it is
necessary to understand how it is laid out by
reading the following carefully:
2 Manual layout
The manual is divided into three different parts
(fig. 1).
The first part contains the general instructions
on how to use and consult the manual; the
nomenclature of the models illustrated in this
manual and the grouping criteria for each
family.
The second part contains booklets with
technical data, hydraulic and wiring diagrams,
troubleshooting instructions and start-up
checks, grouped into product families.
The third part contains the technical data
sheets relative to each component, its basic
characteristics, checking its condition and
replacing and/or servicing.
fig. 1
Parts two and three are preceded by an index
that gives the contents and their order of
arrangement.
3 Topic, numbering, edition
The topic dealt with on each card is also shown
in the top right corner of each page, the part in
the top left corner The pages are numbered in
the bottom corner (fig. 2).
Technical sheet edition date (month and year)
is given between the Part and the Argument on
top of the page.
fig. 2
Part one is laid out with consecutive numbers
(fig. 3).
135
fig. 3
Part two is arranged on two levels (fig. 4). The
first gives the acronym of the family to which
the technical sheet belongs; the number that
follows indicates technical sheet order
sequence inside each family.

Part three is also arranged on two levels (fig.
5); the first is a number assigned to each
component, the second indicates technical

sheet order sequence. Correspondence

4 Updating
The evolution of Biasi products entails updating
the technical assistance personnel and relative
documentation.
The updated documentation which will be sent
to the Assistance Service Centres, whether in
the shape of a circular or technical sheets to be
added to the manual or to replace others, must
be properly inserted.
All technical service personnel must be
informed immediately of their contents.
5 Models
All models of products manufactured are
identified with a name. This name (from here
referred to as model) is determined by the unit
construction characteristics (fig. 6)

The information contained in this manual is
applicable to the following models:

7 Series
The boilers are grouped into families in part two
of this manual, each group including models
with identical construction features and, hence,
with identical maintenance.
Within each family the models differ only in their
nominal thermal capacity or other
characteristics that do not call for different
maintenance.
