DISTANCES OF SAFETY DEVICES ACCORDINg TO THE STANDARD

 The temperature safety sensors must be in place on the machine at a distance no greater than 30 cm from the flow connection. Whenever the 

generators lack a device, those missing can be installed on the generator flow pipe, within a distance no greater than 1 m from the machine.

COMMISSIONINg CHECkS

Before connecting the boiler:

a) wash all system piping thoroughly in order to remove any residues which might compromise the correct functioning of certain system 

components (pumps, valves, etc.).

b) The company recommends installing a magnetic filter  in the generator return, to increase the operational life of the boiler, make it easier 

to remove impurities and increase the overall efficiency of the system.

It is also advisable to perform an inspection using appropriate instruments, to check for any stray currents that may cause corrosion.

c) check to verify that the flue has adequate draught, that it is not narrowed and that other appliances do not discharge into the flue. This is to 

prevent unexpected power increases. The flue fitting can be mounted between the boiler and the flue only after this inspection. An inspection 

of the connections with pre-existing flues is recommended.

ANTI-CONDENSATION DEVICE (MANDATORY)

Make sure a suitable anti-condensate circuit has been realised, which guarantees an appliance return temperature of at least 55°C. The 

automatic thermostatic valve, for instance, is used in solid fuel boilers as it prevents cold water from returning into the exchanger. A high 

return temperature allows efficiency improvement, reduces formation of smoke condensation and prolongs the generator’s life span. The 

manufacturer recommends using the 55°C model with 1” hydraulic connections.

For the products with the *PWM pump control thermostat, installation is considered equivalent to the realisation of a suitable anti-condensate 

circuit in the case where::

 - the heat generator pump is the only one in the installation, or

- there is a plate heat exchanger between the heat generator and the installation, or

- there is a hydraulic compensator or an inertial storage tank (buffer) between the heat generator and the installation
