3.2 Place of installation
The generator can be installed directly outside or in a suitable room with ventilation open-
ings to the outside as prescribed by the current regulations. If there are several burners
or extraction 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 objects or materials, corrosive gases, volatile substances or dusts.
For positioning, leave enough space around the modules for normal maintenance oper-
ations. Make sure the front door opens without hindrance.
B
The air necessary for combustion enters through special openings in the bot-
tom and top part of the unit. Make sure these air passages are not obstructed
in any way.

3.3 Gas and water connections
500
Plumbing connections
500
Make the relevant connections according to the instructions given below. Make the gen-
500
erator connection in such a way that its internal pipes are free of stress. For proper op-
1000
eration and long life of the generator, the plumbing system must be of suitable size and
1000
complete with all the accessories that guarantee regular operation and running.
1000
In particular, provide for all the protection and safety devices prescribed by current reg-
1500
ulations for the complete modular generator. They must be installed on the hot water cir-
cuit delivery piping, immediately downstream of the last module, within a distance of 0.5
1500
m, with no shut-off devices in between. A "Safety Device and Circuit Breaker module"
1500
equipped with internal hydraulic circuit breaker and safety units with ISPESL certification
1500
is available by request. Refer to the price-list or contact our sales network. The unit is not
supplied with an expansion tank; its connection must therefore be made by the Installer.
1500
B
A filter must also be installed on the system return piping to prevent impurities
1500
or sludge from the system clogging and damaging the heat generators.
2000
The filter must necessarily be installed when replacing generators in existing
2000
systems. The manufacturer declines any liability for damage caused to the gen-
2000
erator by failure to install or inadequate installation of this filter.
2000
Water system characteristics
2000
In the presence of water harder than 25° Fr, it is advisable to use suitably treated water,
2500
in order to avoid possible scaling in the boiler caused by hard water, or corrosion pro-
duced by aggressive water. Due to its low thermal conductivity, scaling even just a few
2500
mm thick causes significant overheating of the generator walls, with consequent serious
3000
problems.
3000
Water treatment is indispensable in case of very large systems (containing large
amounts of water) or with frequent introduction of replenishing water in the system. If par-
tial or total emptying of the system becomes necessary in these cases, it is advisable to
refill with treated water.
Gas connection
The gas must be connected to the corresponding union with a rigid metal pipe.
The gas meter must be adequate for the simultaneous use of all units connected to it.
Carry out the generator gas connection in accordance with current regulations. The di-
ameter 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 pressure
loss.
B
Make sure to install a fuel shutoff valve externally with respect to the modules,
enabling the gas to be turned off even without opening the single modules
equipped with key closing.
Connection instructions
ENERGY TOP B is equipped on the inside with 3 manifolds (gas, system delivery and
return) and a condensate drain pipe that facilitate cascade connection and also connec-
tion of a single module to the system. The manifolds are sized for a connection in series
of up to 1000 kW.
The cabinet contains a set of 3 seals (2 for water manifolds, 1 for gas manifold) with re-
spective bolts and nuts, to be used for connection to a subsequent module (connection
in cascade). The optional kit code 042027X0, containing 3 blind flanges and 3 drilled
flanges with respective seals and screws, is available on request for the connection to
the system.
