AERATION PLATES
The SS850 comes with two aeration plates that are factory fitted, in a position for flues
between 3-5.5 m, refer image below. There are a further two aeration plates supplied in the
accessory pack (for flues 5.6-8 m).
To control flame lift and efficiency on long flues (anything over 3 m) it is important the
aeration plates are configured correctly. Refer chart below.
To maintain balance within the combustion chamber, it is important to fit the plates equally
to both sides. The chart below shows the plates required for any given flue length. Fitting
more plates than shown may have a detrimental effect on startup performance, especially
in very cold areas.
If the flue length is less than 3 m the factory fitted aeration plates need to be removed.
Avoid sliding the flue adapter assembly around too much when fitting. This may
cause the gaskets to be incorrectly sealed.
