2.9 EXHAUST AND AIR INTAKE PIPE CON-
NECTIONS
The boiler is equipped with an Authomatic by-pass granting the correct
flow rate of the water in the exchanger in case that the system has a
changeable water flow of the water rate.
You must to protect the discharge pipe of the 3 bar safety valve of the
heating circuit.
The boiler is designed to be connected to a coaxial flue exhaust
system.
Ø 60/100 mm
In addition, it is also possible to use a split (twin pipe) system by fitting
a special adaptor to the flue connector and using the aperture for the
air vent intake located on the top part of the combustion chamber.
To utilise the air intake it is necessary to:
1. Remove the bottom of the air intake by cutting it with a suitable knife;
2. Insert the elbow into the air intake until it reaches the lower end.
(There is no need to use gaskets or sealing componds).
The components marked * are present or absent depending on the
type of flue system used by the installer (see instruction on kit).
