2 Safety instructions and
recommendations
2.1 Safety instructions
DANGER
If you smell gas:
1. Do not use a naked flame, do not smoke, do not
operate electrical contacts or switches ( doorbell,
light, motor, lift, etc..).
2. Shut off the gas supply.
3. Open the windows.
4. Report any leaks immediately.
5. Trace possible leaks and seal them immediately.
6. If the gas leak is before the gas meter, contact the
gas supplier.
DANGER
If you smell flue gases:
1. Switch the appliance off.
2. Open the windows.
3. Report any leaks immediately.
4. Trace possible leaks and seal them immediately.
2.2 Recommendations
WARNING
4Installation and maintenance of the boiler must be
carried out by a qualified professional in compliance
with prevailing local and national regulations.
4When working on the boiler, always disconnect the
boiler from the mains and close the main gas inlet
valve.
4After maintenance or repair work, check all
installations to ensure that there are no leaks.
CAUTION
The boiler must be installed in a frost-free environment.
Keep this document close to the place where the boiler is
installed.

3.3 Operating principle
3.3.1. Shunt pump
The boiler is supplied without a pump. When choosing a pump, take
account of the boiler resistance and system resistance.
¼ See chapter: "Technical specifications", page 12.
If possible, install the pump directly under the boiler on the return
connection.
¼ See chapter: "Connection of the heating circuit", page 20.

CAUTION
The pump may have a maximum input of 200 W. Use an
auxiliary relay for a pump with a larger input.
3.3.2. System in cascade
The boiler is ideally suited for a cascade system. There are a number
of standard solutions available. For example:
4Cascade sets (quick assembly) for the installation of 2 to 6 boilers
next to each other or 3 to 6 boilers mounted back to back on a free-
standing frame. When the boilers are mounted next to each other,
they can be mounted either on the wall or on a free-standing frame.
4Low loss headers for a cascade system of 2 or 3 boilers (Quinta
Pro 45 and/or Quinta Pro 65). The flow and return of each boiler
can be directly connected to these.
Please contact us for further information.
3.3.3. Calorifier connection
A calorifier can be connected to the boiler. Our product range includes
various calorifiers.
Please contact us for further information.
The calorifier can be connected to the boiler in two ways:
4Using a three-way valve.
4Using a calorifier pump.
3.3.4. Water flow rate
The boiler's modulating control system limits the maximum difference
in temperature between the heating flow and return and the maximum
speed at which the flow temperature increases. For this reason the
boiler is, so to speak, insensitive to a flow which is too low.
In all cases, maintain a minimum water flow of 0.4 m3/h.
