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.
