Installation
Accy No.: 303 926
The appliance is supplied ready-fitted
with the connection-piece for the
60/100 air/flue duct system.
• Loosen the four screws (2) and
pull the appliance connection-
piece (1) upwards to remove it.
• Push the appliance connection-
piece with the selected connection
diameter down from above,
inserting the push-in end onto the
sleeve of the flue collecting
chamber. Now push the
appliance connection-piece
downwards until the flange comes
into contact with the low-pressure
chamber.
• Refit the fixing screws (2).
The seals are sensitive to
mineral oil-based grease
products.
For this reason, the seals must
not be greased. If the seals
need wetting to aid in
installation, use water only.
