7 INSTALLATION
Before
connecting
the boiler, the following operations must be completed:
-
Thoroughly clean all the
system pipes
in order to remove any foreign matter that could affect correct operation
of the boiler;
-
Check that the
flue
has an
adequate draught
, that there is no narrowing of passages and that it is free from
debris; also check that other appliances do not discharge into the flue (unless designed to serve several utili-
ties).
See the regulations in force
.
7.1 THERMAL PLANT
7.1.1 BOILER ROOM
As a rule, regulations in force should be always observed
.
Premises in which boilers will be installed should be sufficiently ventilated and guarantee access for ordinary and
extraordinary maintenance operations.
7.2 BASE
The boiler should be installed on a stand, 100/200 mm high, in order to create an air trap in the condensate drain,
which is designed to retain fumes and evacuate water.
IMPORTANT
Make sure the boiler supporting base is perfectly horizontal. The door must be at a uniform slope to pro-
vide a proper drainage of the condensate to the smoke box.
7.3 CHIMNEY
The smokestack must be dimensioned as to applicable regulations.
WARNING
The flue gas temperature of this boiler is very low compare to the traditional non-condensing boilers,
therefore, there is a very high humidity density. For this reason the boiler chimney must be water resistant,
acid condense resistant and insulated to warrant sufficient draught.
