Figure 2.3:
Exhaust flue pipe
The room where the heat generator should be installed must not have mounted aspirators because they can reduce the pressure in
the environment.
It is strictly prohibited to close the air intakes.
The exhaust pipe should be cleaned at least once a year; we recommend performing a thorough cleaning of the pipe and its
connections.
After longer period of inactivity and before start up check for blockages.
ATTENTION
: The smoke discharge must be executed in accordance with the provisions of the applicable regulations.
ATTENTION
: Check with appropriate tool if the minimum pressure of 12 Pa is in the chimney.
SM OKE DIS CHA RGE ON EXTERNAL WALL
One of the possible solutions is to position the pellet unit near the external wall of the house and discharge exhaust gases directly outside
(Figure 2.4). Below you can find certain number of indications that point out the standard for this type of system configuration
-
Always make sure there is an inspection opening (I) which will enable regular cleaning activities and removal of possible
accumulated condensation;
-
‘T’coupling must be wind and water resistant;
-
Make sure the discharge pipe is properly insulated in the section that passes through the wall.
If the discharge pipe is completely outside, it must be made of stainless steel with double sides in order to provide better resistance to
atmospheric conditions as well as the proper temperature of exhaust gases.

Combustion smoke can be also discharged by already existing traditional chimney (Figure 2.5), provided it complies with applicable
standards. Main characteristics of a good chimney (C) are listed below:
-
Proper insulation, especially of the outer part which is exposed to weather conditions;
-
Constant internal diameter (smaller diameter parts should not be used);
