Make sure you have always guaranteed the mechanical stability of the duct.
The hole, for the passage through the wall of the exhaust and air intake pipe,
must not be concreted: the flue gas exhaust must be free to slide through the
hole so that it can be extracted later.
For this purpose, the wall cover rosettes supplied with the flue gas exhaust kit
can be used to cover the empty space of the hole.
IMPORTANT:
LEAVE A SPACE NOT LESS THAN 30 CM ABOVE THE APPLIANCE TO ALLOW ANY MAINTENANCE INTERVENTION ON THE UPPER
PART.
TO AVOID POSSIBLE WATER INFILTRATION DURING THORMS, WE RECOMMEND A SLIGHT SLOPE DOWNWARDS OF THE AIR
