5.3 Air regulation
The Heat Pure has two types of air
regulation:
The primary air is regulated automatically
and ensures that the wood is easily
ignited. This creates a glowing bed of
carbonised wood for an optimal
gasification process. After burning for
approximately 50 minutes, this valve
closes automatically, which will produce a
high heat output.
When the primary air valve is closed, the
air enters the combustion chamber
through the top spoiler. This top spoiler
also ensures that the window remains
clean. When the draught in the chimney
exceeds 12 Pascal, and (very) dry wood is
being burned, you will be able to keep the
window clean for a considerable length of
time.
However, soiling can occur on the window
when the fire is smothered by closing the
air regulation.
The flames can be regulated by inserting
the side of the key into the groove
positioned on the right-hand side of the
Heat Pure. Use the right side of the
handle (figure 3). By moving the key to
the left, you will minimise the air supply
to the top spoiler; the fire will burn more
calmly (provided that the primary air
valve has closed automatically). By
moving the key to the right, the air supply
to the fire will increase and the fire will
burn more strongly.
