NB: For the C52 type, do not fit the flue and air duct terminals on opposite walls of the building. The air duct (for horizontal discharges)
must have a maximum length of 10 metres (6m for model 140 Fi).
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.
