narrow passages, hallways or similar spaces. When the boiler is connected to the chimney, the chimney must be
checked on openings. If there are openings, they must be sealed.
Flue gases exhaust must be grounded in accordance with local regulations. Grounding is legally required
and must be carried out independently of the ground tank.
Flue gases exhaust must be performed in accordance with UNI 9615-9731, UNI 10683-N1856-1. Chimneys that
are in bad condition, or are made of inappropriate material (asbestos, galvanized sheet metal, etc.) with rough or
porous surfaces, are not complied with the law and endanger the operation of the boiler. Smoke can be easily
exhausted through a traditional chimney (see below given figure), provided that the following rules are respected:
-
check the condition of the chimney
-
if the chimney is old it is advisable to renew it by inserting a metal tube properly insulated with glass wool
or vermiculite
-
it is possible to let the smoke go directly into the chimney, provided that its dimensions are 200x200 mm or
maximum diameter is 200 mm and that it is equipped with an inspection hole
-
in the event of a larger size chimney, it is necessary to install the corrosion proof pipe of maximum
diameter of 200 mm. The pipe must be properly insulated.
-
make sure the connection is properly sealed to the chimney
-
avoid contact with combustible materials and, in any case, insulate them with fire resistant material

The diameter of the pipe is dependable on the power
of the boiler. Operation of pellet boilers is designed
for flue gas exhaust pipe of 80 mm diameter. In
certain conditions, it is recommendable to use the
pipe of 100 mm diameter, as shown in Figure 2. In
the event when you have to use the pipe of 100 mm
diameter, connect it to the boiler with T-connection of
80 mm diameter and extend the chimney with a
reducer of 80/100 mm diameter.
