3. INSTALLATION
3.1 General Instructions
THE BOILER MUST ONLY BE INSTALLED BY QUALIFIED PERSONNEL, IN COMPLI-
ANCE WITH ALL THE INSTRUCTIONS GIVEN IN THIS TECHNICAL MANUAL, THE
PROVISIONS OF CURRENT LAW, THE NATIONAL AND LOCAL REGULATIONS,
AND THE RULES OF PROPER WORKMANSHIP.
ENERGY TOP B is a heat generator arranged to operate alone or in cascade (bank).
When two or more generators are installed in cascade with the original kits ENERGY
TOP B, respecting the prescriptionsFERROLIof this manual, they can be considered as
a single heat generator of total power equal to the sum of the powers of all the units con-
nected in cascade.
All the requirements of the current standards and regulations applicable to this "equiva-
lent" total heating capacity generator must be met. In particular, the place of installation,
safety devices and fume exhaust system must be adequate for the total heating capacity
of the bank of units.

In fact, each ENERGY TOP B is a complete and independent heat generator, equipped
with its own safety devices. In case of overtemperature, no water or no circulation in the
unit , the protection devices cause the unit to shutdown , preventing its operation.
The installation instructions given in the following paragraphs concern single units and
connection in cascade.
Given below are the possible configurations for connection in cascade.
