After positioning the thermal stove and installing all the smoke discharge pipes, the hydraulic plant can
be connected. First of all make sure that the bleeder valve ( 1 ), on the top right-hand side of the boiler
(see images below) is closed when the water is lling as shown in the gure below.
Connect the boiler connections (see gures below) to the water plant, bringing the plant’s pressure from
1 to 1.3 bar when the thermal stove has not yet been lit (if the plant has an open tank and not a closed
one, the setting reserved for authorised technicians must be changed).
Now proceed with bleeding the water plant from the valve tted on the boiler or from the valves tted on
the radiators. This operation can be carried out several times even after the boiler has been switched
on since, when the water temperature starts to increase, the air bubbles move towards the upper part
of the boiler itself.
When bleeding the boiler, make sure that the electrical parts near the valve do not get wet! If this should
happen, do not switch the boiler on but use a hair-dryer to dry the electronic board.
