2.1 Back draught shutters

Are suitable for intermittent operation only
therefore are not to be fitted when using
in continuous operation.
On using intermittent operation we
recommend that the back draught shutters
are not fitted when duties are set less than
15 l/s and for installations other than directly
through the wall to avoid failure of the shutters
opening. Shutters are clipped into place.
Ensure the spring is fitted in lower position.
