excessive air not limited by the draft regulator. In
these cases it is necessary to partially restrict the
air passages, as shown in figure 21 and 22, so as to
compensate for the excess of draft. As a rule these
adjustments must be made, if necessary, only dur-
ing installation.
The adjustment procedure is as follows: open the
fire door, loosen the fixing screws, slide the ad-
justment plates and then fix the screws again. The
adjustment plate slides horizontally and opens or
closes the passage of air according to the indicat-
ed direction. It is recommended not to close the
passage of air completely, because this could lead
to irregular operation which could dirty the glass.
