- The water manostat cables that are prearranged in the boiler must be connected to the
hydraulic kit (optional).

7.21 REAR PANEL
If maintenance must be performed on a component of the stove, the rear panel can be removed (if the distances from the walls
allow it), otherwise, the maintenance can be performed by removing the side of the stove.
To remove the rear panel, remove the seven rear screws “a” and pull panel “L” away.
The “L” panel can also be removed with the stove installed since its shape corresponds with the smoke outlet pipe. Plate “L1” sup-
ports the flue pipe as it is secured to the stove using the two screws “a”. With the stove installed you must only remove plate “L1” if
the smoke pipe must be removed, otherwise remove only plate “L”.
