Please observe that combustion air openings and flue
pipes are not reduced in size or closed. Make end user
aware of these guidelines and their potential danger.
Clean the chimney and the flue gas tube at regular
intervals.
Check if the draft inducer is clean and in a good
condition.
2. Flue gas temperature
The flue gas temperatures are approximately the same for all AutoPellet covered in this manual.
The dewpoint of flue gas with wood pellets (max. 10% water content) is approx. 120°F.
It is possible to increase the flue gas temperature to prevent condensation inside the chimney and avoid
damage due to damp. Only authorised installers may increase the flue gas temperature.
Note:
The increase in flue gas temperature results in reduced efficiency and thus increases fuel
consumption.
3. Negative pressure of the chimney
The boiler must be connected to a chimney or a vertical venting system that is capable of handling and
producing a negative breeching pressure of –0.4 “WC. Use a draft gauge to verify the indicated draft va-
lue, adjust barometric damper as required. Drill a small hole in the connection pipe at about 2in/ 50mm
from the boiler flue outlet and use this hole as your measuring point.
Chimney draft
The suction effect of the chimney draft must extend all the way to the boiler flue pipe connection. The
maximum flow rate that can be drawn through the chimney limits the maximum performance of the chim-
ney connection. The boiler performance must be reduced if the chimney does not possess the necessary
cross-section. This may only be performend by authorised personnel.
4. Cleaning
Clean the flue gas tube and chimney regularly. Solid fuel burning appliances need to be cleaned fre-
quently because soot, creosote, and ash may accumulate. The hotter the fire, the less creosote is depos-
ited. Cleaning intervals can vary in warm periods due to this and become more frequent.
