Operating Instructions and Installation Instructions

IT IS STRONGLY RECOMMENDED TO WASH THE ENTIRE SYSTEM BEFORE CONNECTING THE
STOVE IN ORDER TO GET RID OF RESIDUES AND DEPOSITS.
Upstream from the stove, always install gate valves so as to disconnect it from the plumbing
system should it be necessary to move it, or when it requires routine and/or special
maintenance. Connect the stove using hoses so that the stove is not connected too tightly
to the system, and to allow slight movements.
The pressure discharge valve (C) must always be connected to a water drain pipe. The pipe
must be adequate to support the water’s high temperature and pressure.

8.6 SYSTEM FILLING
To ll the system, the stove can be equipped with an end piece (optional) with a check valve (D), for manual
lling of the heating system (if the optional is not installed, the lling tap on the main boiler will be used). During
this operation, any air in the system is released from the automatic vent valve located under the top.
To allow the valve to vent, it is recommended to loosen the grey cap by one turn and leave the red cap locked
(see gure). The lling pressure of the system WHEN COLD must be 1 bar. If during operation the system pressure
drops (due to evaporation of gases dissolved in the water) to values lower than the minimum ones indicated
above, the user must use the lling tap to bring the pressure back up to its initial pressure.
For proper operation of the stove WHEN HOT, the pressure in the boiler must be 1.5 bar.
To monitor system pressure, the end piece (optional) is equipped with a pressure gauge (M).
Upon completion of this lling operation, always close the tap.
