Children and people with disabilities or without
experience and specific knowledge are forbidden to use
the heating unit unless they are assisted by a qualified
person responsible for their safety.It is forbidden to use
electrical devices or equipment, such as switches,
appliances, etc. if there is a smell of gas or un-burnt
products. If so:
- ventilate the room, opening doors and windows;
- close the gas valve at the mains;
- immediately call in the Technical Assistance Centre
or professionally qualified personnel.
a
It is forbidden to touch the heating unit with bare feet
or parts of the body wet.
a
It is forbidden to start on any technical or cleaning
jobs before disconnecting the heating unit from the
power mains.
a
It is forbidden to alter the safety and adjustment
devices without permission and instructions from the
heating unit manufacturer.
a
It is forbidden to obstruct the condensate drain.
a
It is forbidden to pull, detach, twist the wiring coming
out of the heating unit, even if unplugged from the
power supply.
a
It is forbidden to obstruct or reduce the size of air
vents.
a
It is forbidden to expose the boiler to atmospheric
agents (if it is not a specific unit for outdoors).
a
It is forbidden to leave containers or flammable
substances in the premises where the boiler is
4
installed.
a
Do not dispose of packaging material into the
environment, or leave it within the reach of children,
since it can become a potential hazard. Dispose of
packaging material in compliance with applicable
legislation.
a
The user is forbidden to open the cupboard containing
the heating unit. Any jobs on the inside of the latter
must be done by the Technical Assistance Centre or
by qualified personnel.
a
It is forbidden to discard the product as household
waste. At the end of its service life, it can be
consigned to specific selected waste centres
provided by the local authorities or else to dealers
providing this service. Disposing of a domestic
appliance separately will prevent possible harmful
consequences for environment and health derived
from inappropriate disposal, likewise making it
possible to recuperate the materials it is made of with
substantial savings in energy and resources.

TECHNICAL FEATURES
3 .1 Main features
is a modular condensing, premixed,
Power Plus Box 1001
jet heating unit, comprising a modular unit at 26 to 128 kW
equipped with weather adjustment device.
The efficiency of the generators reaches 109% based
on the lower heat potential of natural gas (Hi) making it
possible to use a flue manifold entirely made of plastic
(PP). The system also enables continual modulation of the
gas and combustion air flow.
The Power Plus Box 1001 heating unit is the optimum as far
as operating costs (up to 109% efficiency per Hi, see Figure
1), reliability and flexibility is concerned. Rapid connection
to any type of heating and domestic hot water system
with accumulation is in fact possible owing to a special
more powerful heat exchanger, new electronic control,
modulating electronic circulator and high efficiency.
Furthermore, the "master" board, supplied with each
heating unit, ensures the latter a simple conFiguretion and
enables it to be adapted to any type of system, optimizing
its performance in terms of creating comfort and cutting
down on consumption.
All the safety devices provided in the INAIL "R" File for
this particular application, have been installed on the flow
manifold, downstream from the last combustion unit.
A special water compensator is housed inside the hood
with attachments for simple connection to the systems
directly controlled by the master board which is supplied
with the heating unit:
- Direct system (high temperature)
- Mixed system (low temperature)
- Hot water system.
Distribution units are available as an accessory for each of
the above mentioned systems.
The heating unit thus becomes a complete, versatile
functional "system" to install in a variety of plant typologies.
All the systems and relevant functional components
(circulators, mixer valve and temperature probe) are
entirely controlled by the master board and are connected
up to the latter, without the help of additional boards.
Room thermostats in the unit's system-related areas can
also be connected up to said board.
The system can also be extended to numerous additional
zones by a board called "zone master", which is not
included in this manual.
