NOTE:
For the C52 type, do not fit the flue and air duct terminals on opposite walls of the building. The maximum length of the air
duct is 10 metres.
If the discharge duct is longer than 6 metres, install the condensate collection kit, supplied as an accessory, near the boiler.
IMPORTANT:
if fitting a single flue duct, make sure it is adequately insulated (e.g.: with glass wool) wherever the duct passes
through building walls.
For detailed installation instructions, consult the technical data provided with the accessories.

IMPORTANT:
Make sure there is a minimum downward slope towards the outside of 1 cm per metre of duct length. If the con-
densate collection kit is installed, the discharge duct must slope down towards the boiler.
