PLUMBING SYSTEM CONNECTION
IMPORTANT!
The connection of the stove to the plumbing system must be carried out ONLY by specialized personnel who are
capable of carrying out installation properly, in compliance with current standards in the country of installation.
The manufacturer will not be held responsible for damage to persons or things in the event of failed operation if the
aforementioned warning is not complied with.
It is important that ONLY qualified engineers are used to fit and commission the appliance in ALL cases. The installing
engineer MUST hold a QCF recognised biomass qualification. Any company using sub-contractors MUST ensure they also
hold the relevant qualifications (ONLY FOR UK).

IMPORTANT!!!
CLEAN THE ENTIRE SYSTEM BEFORE CONNECTING THE STOVE, IN ORDER TO REMOVE ALL RESIDUE AND DEPOSITS.
Upstream from the stove, always install shutters 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 too strictly connected to the system, and to allow slight
movements.
