2.3 Place of installation
The generator can be installed directly outside or in a special room with ventilation openings to the outside
as prescribed by current regulations. If there are several burners or exhauster units that can work together
in the same room, the ventilation openings must be sized for simultaneous operation of all the units.
The place of installation must be free of flammable materials or objects, corrosive gases, powders or vola-
tile substances.
For positioning, leave sufficient room around the modules for normal maintenance
work.
In particular, make sure the front door can open freely.
The air needed for combustion is drawn in through special openings in
the bottom of the door. Make sure these air passages are not obstructed
in any way.
2.4 Gas and water connections
Plumbing connections
Make the connections to the corresponding connections according to the fol-
lowing instructions. Make the generator connection so that its internal pipes are
free of stress. For correct operation and long life of the generator, the plumbing
system must be well-proportioned and always complete with all the accessories
that guarantee regular operation and running.
In particular, provide for all the protection and safety devices required by current standards for the complete
modular generator. They must be installed on the hot water circuit delivery piping, immediately after the
last module, within a distance of not more than 0.5 m, without shut-off devices in between. The unit is not
supplied with an expansion tank; its connection must therefore be carried out by the Installer.
A filter must be installed on the system return piping to prevent dirt or sludge from the system
clogging and damaging the heat generators.
The filter must be installed when replacing generators in existing systems. The manufacturer is not
liable for any damage caused to the generator by failure to install or inadequate installation of this
filter.
Characteristics of system water
In the presence of water harder than 25° Fr, suitably treated water must be used in order to avoid pos-
sible scaling in the boiler, caused by hard water, or corrosion produced by aggressive water. It should be
remembered that, because of the low thermal conductivity, scaling of just a few mm thick causes significant
overheating of the generator walls, resulting in serious problems.
Water treatment is indispensable in the case of very large systems (containing large amounts of water) or
with frequent introduction of replenishing water in the system. If partial or total emptying of the system
becomes necessary in such cases, it is advisable to refill it with treated water.
Gas connection
The gas connection must be made to the corresponding connector with a rigid metal pipe.
The capacity of the gas meter must be sufficient for the simultaneous use of all equipment connected to it.
Make the generator gas connection in accordance with current regulations. The diameter of the gas pipe
leaving the generator does not determine the diameter of the pipe between the unit and the meter; it must
be chosen according to its length and loss of head.
It is advisable to fit a gas non-return valve on the outside of the modules, for shutting off the gas
supply even without opening the single modules equipped with key closing.
