Working combustion air
If used with a closed door, the Heat Pure
takes the combustion air directly from
the connection at the rear
(A)
or base
(A’)
of the Heat Pure. This combustion
air is guided into the combustion
chamber via de air control
(B)
and the
primary thermostat
(C)
, where it is used
as primary or secondary combustion air.
Primary combustion air
(P)
The thermostat regulates this air flow
automatically. When the Heat Pure is
cold the thermostat ensures that air
enters the combustion chamber via the
lower spoiler. As the Heat Pure warms
up, the air flow will gradually decrease.
After approximately 50 minutes, the
Heat Pure is so warm, that this air flow
stops altogether.
The primary air control is 100%
automatic and cannot be influenced by
yourself.
Secondary combustion air
(S)
The air flow is regulated manually via
the operating feature to the right of the
appliance
.
Via risers to the left and right of the
combustion chamber, this air is warmed
up and guided to the combustion
chamber via the upper spoiler.
The secondary air flow is used to
regulate the flames and to keep the
glass door clean. This air flow may
therefore never be completely closed off.
