2.3 Gas and water connections

Plumbing connections
Make the relevant connections according to the instructions given below. Make the generator connection in such a way
that its internal pipes are free of stress. For proper operation and long life of the generator, the plumbing system must
be of suitable size and complete with all the accessories that guarantee regular operation and running.
In particular, provide for all the protection and safety devices prescribed by current regulations for the complete modular
generator. They must be installed on the hot water circuit delivery piping, immediately downstream of the last module,
within a distance of 0.5 m, with no shut-off devices in between. A "Safety Device and Circuit Breaker module" equipped
with internal hydraulic circuit breaker and safety units with ISPESL certification 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.
B
A filter must also be installed on the system return piping to prevent impurities or sludge from the system clog-
ging and damaging the heat generators.
The filter must necessarily be installed when replacing generators in existing systems. The manufacturer de-
clines any liability for damage caused to the generator by failure to install or inadequate installation of this filter.
Water system characteristics
In the presence of water harder than 25° Fr, it is advisable to use suitably treated water, in order to avoid possible scaling
in the boiler caused by hard water, or corrosion produced by aggressive water. Due to its low thermal conductivity, scal-
ing even just a few mm thick causes significant overheating of the generator walls, with consequent serious problems.
Water treatment is indispensable in case of very large systems (containing large amounts of water) or with frequent in-
troduction of replenishing water in the system. If partial 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 con-
nection 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 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
Reply 51 - 71 - 101 is equipped on the inside with 3 manifolds (gas, system delivery and return) and a condensate drain
pipe that facilitate cascade connection and also connection of a single module to the system. The manifolds are sized
for connecting up to 5 modules in series. The cabinet contains a kit of flanges, seals and screws for the connection.
To connect a single module - fig. 16
• After determining on which side of the module to make the water and gas connections, connect the flanges with the
joining section contained in the kit on that side after suitably welding them to the system pipes. Make sure to correctly
to fit the seals contained in the kit.
• Connect a Ø40 pipe to the condensate drain pipe for removing the condensate produced during operation (see
fig. 37).
• Fit the blind flanges contained in the kit on the opposite side of the module, inserting the special seals.
