4. If the measured value is outside of the values given in the table, cor­
rect the gas/air ratio.
Note
The 210-80 and 210-120 boilers are equipped with a restrictor on
the gas valve unit. They can therefore only be set to part load.
5. Using the adjusting screw, set the percentage of O
type being used to the nominal value. This should always be inside
the highest and lowest setting limit. The direction in which the ad­
justment screw must be turned to increase or decrease the gas flow
is indicated on the gas valve unit.
6. Check the flame through the inspection window.
Note
The flame must not blow off.
