3.3 EXHAUST GAS SYSTEM
It is always important to know that the exhaust system is as important as the pellet stove.
The installation of the exhaust system should be performed by authorized persons. The authorized person
should be guided by the following data
:
15 kW
Draft of the pellet stove
Pa
12
Mass of the combusted air
g/s
5.3
CO measured for 13% oxygen
%
0.0196 0.015
Temperature of the exhaust gases

3.4 EXHAUST GASES AND INSTALLATION
The exhaust gas system operates as a result of depression which occurs in the combustion area. It is very
important for the exhaust gas system, above marked as SIG, to be made of certified materials and:
- to be hermetically closed, meaning the system should be made of special pipes with adequate silicon sealer.
- to be able to operate under high pressure and under temperature ranging from 200-250
o
C (pipes with
thickness not less than 1 mm is recommended).
If the pellet stove is connected to the existing system, the system should be checked by an authorized person.
The system cannot be installed indoors. Periodical cleaning of the exhaust gas system is recommended.
3.5 USABLE PIPES
The pipes used for the exhaust gases should be resistant, smooth from inside, made of metal and to have
silicon sealer. The diameter of the pipes up to 3 m long should be 80 mm or 100 mm for pipes longer than 3 m
or over 1200 m height above sea level.
The length is calculated along the whole horizontal and vertical length, counting each curve of 90
o
as 1 m of
length.
ATTENTION
Do not connect the system to the existing system or to the aspiration system.
