Raising the flue gas temperature

You can find out the specified flue gas temperature for the
boiler by referring to the specifications (
page 10).
If you discover when testing the system that the flue gas
temperature is too low for the flue (risk of condensation
formation), you can raise the flue gas temperature by one
or more of the following measures:

– Removing hot gas baffle plates

– Removing the hot gas check plate

V Shut down the heating system (
page 50).
Warning: Risk of burning from touching hot
boiler parts.
V Wear appropriate protective gloves or use
pliers.

flue gas temperature.
V Open the burner door; to do this, remove the two
lateral hexagon bolts.
V Remove the hot gas baffles towards the front.
V Close the burner door with both hexagon bolts. Tighten
the hexagon bolts evenly to properly seal the burner
door.

7.5.2 Removing the hot gas check plate
You can remove the hot gas check plate to further raise
the flue gas temperature if, after the removal of the hot gas
baffle plates, the flue gas temperature is still too low.
