If used with an open door, the
air need of the Heat Pure
changes. The opening at the
front will cause large volumes of
air to be sucked into the
appliance. This air will be taken
from the room the appliance is
installed in.
With an opened door, the built-in
valve ensures that the passage
to the combustion chamber is
closed (see figure). The
connected air is re-routed to the
convection casing, where the air
is warmed before it flows into
the room.
This air then becomes available
in the room where the appliance
is installed so it can be used in
the combustion process.
