19. Heating at Low Thermal Output
(during
Transitional
Seasons)
You can vary the thermal output of your Ottawa by adjusting
the quantity of fuel used.
NOTE!
Do not attempt to slow down the combustion
by reducing the air supply. When heating with
wood, this can result in an incomplete burning
process and pose the risk of an explosive-like
combustion of the accumulated wood gases
(defl agration)
20. Emptying the Ash Drawer
As a safety precaution, please make sure to wait until the
ashes are cold before you dispose of them. While the ash
collects during the fi re, the lid is located under the ash drawer.
Remove both the ash drawer and the lid located underneath
it. Slide the lid onto the ash drawer so that it is closed; this
prevents ashes from fl ying around, which in turn means your
home stays clean. To place the ash drawer back into the stove,
proceed in the reverse order.
CAUTION!
Piled up ashes can impair or even block the
supply of primary air supply to the stove.
Please ensure that the air supply path for the
primary air between the ash drawer and the
bottom of the ash compartment remains clear.
18. Banking the Fire and Raising the Temperature
Keep the stove set as described above until the brown coal
briquettes are thoroughly burnt. Then close the primary air (I)
and the fi re grate. Slide the secondary air slider (II) to position
2/3.
NOTE!
While the stove is in operation, the secondary
air slider should never be completely closed.
To raise the temperature of the fi re, stir up the rest of the
glowing embers with the fi re grate slider. Open the primary air
(I) and add new logs to the fi re.
