Secondary Air; Initial Operation - HASE Granada Mode D'emploi

8.2 Secondary Air

The secondary air is guided into the fi re box via air ducts from the top. It supplies the fi re
box with the volume of preheated oxygen necessary to completely burn off the wood gas
and ensures that the fi re box window remains free of soot.
For regulating the secondary air, the following general rule applies: a small fi re
requires little secondary air; a large fi re requires ample secondary air.
If the secondary air valve is closed too tightly, there is the risk of the fl ue gases not com-
pletely burning (smouldering fi re) and/or soot build-up on the fi re box window or that the
amassed wood gases will burn explosively (over fi ring/defl agration).
Please note: Burning wood when the primary air slider is opened too wide poses the risk of
overheating the stove (forge fi re effect). During operation, the secondary air slider should
never be completely closed. The fi re box door and ash compartment must always be tightly
shut.

Initial Operation

The fi rst time you operate a stove, smoke and odours can develop as organic components
in the coating, sealing strips and lubricants used in the production process burn off.
At a higher combustion temperature, this one-time process can take between 4 to 5 hours.
To achieve this higher combustion temperature, please increase the fuel quantity recom-
mended in Section 11, Adding Wood or Fuel/ Heating with Nominal Thermal Output, by
approximately 25%.
To prevent adverse effects on health, nobody should stay in the room(s) where the stove
is being operated unless absolutely necessary. Make sure the room is well-ventilated and
open the windows and outside doors. If needed, use a fan for faster air circulation.
If the maximum temperature isn't reached during the fi rst heating operation, you
may notice an odour for a short period of time during subsequent operations
as well.
During shipment to you, condensation moisture can accumulate in the stove's interior,
which may possibly lead to the appearance of condensation or water on the stove or fl ue
pipes.
Please dry off these damp areas immediately.
The surface of your stove was degreased in a sandblasting machine before being lacquered.
Despite careful and thorough inspection, there may still be some blasting material (small
steel pellets) in the stove body, which can fall out when your stove is being installed.
To prevent any damage, please immediately vacuum up these little steel pellets
with a vacuum cleaner.
The Granada / Kyoto may only be operated when the fi re box door is closed; the fi re box
door may only be opened to add fuel.
