Hot adjustment (with first start for function check, still with closed ball valve)
Hot adjustment of the burner
In the "Hot adjustment" menu items, the fine adjustments for the air and gas flap
are made for the ten adjustment points P0 to P9 using the exhaust gas analysis.
Then, the definitive working range of the burner is defined based on the bu (lower
operating point) and bo (upper operating point) thresholds.
Note: if normal shutdown takes place during the adjustment procedure,
select the "Hot adjustment" menu item immediately after activating
adjustment mode. By doing this, you will keep the values of the points that
have already been adjusted, while a recalculation is carried out in the "Cold
adjustment" menu.
· For burner start, set the Manual/Auto burner selector switch to manual on the
control panel, ensure heat request via boiler regulator.
