Place Of Installation; Installation In Older Systems And Systems Requiring Modernisation - Riello TAU 55 UNIT Installation And Maintenance Manual

Because this TAU UNIT, boiler generates over 35 kW of
heat output, it MUST be installed in a dedicated boiler
room in compliance with applicable technical standards.
The boiler must also be provided with a suitable conden-
sate collection system and flue gas vent system (see the
relevant sections in this manual).
b
In Belgium, boilers must be installed according to
standards NBN D51.003, NBN B61.002 (heat output
< 70 kW), and NBN B61.001 (heat output >70 kW).
NOTE! See the table on the previous page for boiler dimensions.

INSTALLATION IN OLDER SYSTEMS AND SYSTEMS REQUIRING MODERNISATION

When installing these boilers in older systems or systems requiring modernisation, always perform the following checks.
- Make sure that the flue is able to withstand the tem-
perature of the combustion gases and that it has been
designed and made in compliance with applicable
standards. The flue must also be as straight as pos-
sible, sealed, insulated and not blocked or choked.
- Make sure that the flue is fitted with a condensation
drainage union.
- Make sure that the electrical system has been installed
by a qualified electrician in compliance with applicable
standards.
- Make sure that flow rate, head and direction of flow of
the pumps are suitable and correct.

PLACE OF INSTALLATION

b
When installing the boiler, allow sufficient space
around it to access all safety and control devices
and to permit easy maintenance.
b
Make sure that the boiler's index of electrical protec-
tion is adequate for the characteristics of the room
where it is to be installed.
a
These boilers must be installed indoors. They are
not designed for outside use.
H
- Make sure that the fuel feed line and any storage tank
are made and installed in compliance with applicable
standards.
- Make sure that expansion vessels are big enough to
contain the additional volume generated by thermal ex-
pansion.
- Make sure that the central heating circuit has been
flushed out to remove all sludge and lime scale, and
that it has been bled and seal tested.
- Make sure that a suitable water treatment system is
installed. (See the "Water in central heating systems"
section.) Refer to the r catalogue for details of spe-
cific products.
