Picture 33. Secondary air regulation: the regulation is open in correspondence of the position indicated with
letter A (bigger inflow of secondary air than primary air), while it is closed in correspondence of the
position indicated with letter B (bigger inflow of primary air than secondary air).
On STP thermal cookers the glass cleaning air is
fixed and set so that the combustion is optimal and
the glass of the fire door is clean. When the cooker
is installed on a chimney with high draught, it is
possible to experience an excessive air inflow not
limited by the draught regulator.
In this situation it is necessary to restrict partially
the air flow as indicated in picture 34, so that the
excessive draught is compensated. This regulation
shall be done, when necessary, only during the
installation of the cooker. To make the regulation:
open the fire door, release the screws, scroll the
regulating plate and then fix the screws again. The
regulating plate scrolls horizontally and opens or
closes the air flow according to the indicated direc-
tion. Do not close completely the air flow because
it may cause a not regular working of the cooker
that could make dirty the glass of the fire
door.
