THE BOILERS MUST BE INSTALLED IN ROOMS THAT MEET THE FUNDA-
MENTAL VENTILATION REQUIREMENTS. OTHERWISE THERE IS A DAN-
GER OF ASPHYXIA OR POISONING.

Important
The unit is a "C-type" with sealed chamber and forced draft; the air inlet and fume outlet must be connected to one of
the extraction/suction systems indicated below. Before proceeding with installation, check and carefully observe the
above instructions. Also, comply with the provisions on the positioning of wall and/or roof terminals and the minimum
distances from windows, walls, ventilation openings, etc.
In case of installation with maximum resistance (coaxial or separate flue) it is advisable to carry out a calibra-
tion procedure [AUTO SETUP] to optimize boiler combustion.
