discharge to the outside
The discharge should not be connected to a duct which is
also used for other purposes under any circumstances.
Bear in mind any local regulations concerning the ventilation
of gas appliances.
The discharge may pass straight through the wall to the
outside, provided that the wall opening is protected - by
means of a grating - against rain, leaves, and the like getting
in. The passage of the discharge may not be restricted by
the wall grating by more than 20%.
We advise the use of as large a discharge duct as possible.
A duct with a smaller diameter will have a low extraction
capacity and produce higher noise levels. Bends produce
resistance. Make sure that the duct has a smooth run and
has as few bends as possible. Draw the flexible pipe out as
far as possible. Before starting to drill, check that there are
no installed pipes present.
The discharge stump has a diameter of 150 mm. It is best if
the discharge pipe also has this diameter.
A reducing piece (150 mm to 125 mm) is supplied with the
appliance for connection to a 125 mm discharge pipe.
