OPERATING INSTRUCTIONS
— 8 —
IMPORTANT
The best moment to reload the stove is when a good layer of cinders
has set itself. If this layer is too thin, the way to reload it is repeating
the initial lighting procedure (page 6).
IMPORTANT
If you follow these instructions you will generate an effective
combustion that does not produce smoke when you start a fire
in your stove.
How do I reload firewood into the
stove?
1. Adjust the Primary Air Control to “maximum”
and open the door of the firebox (upper door).
2. Place the dry firewood logs on the cinders
inside the stove. Logs must be loaded front to
back as shown in the figure at right. As is the
case when lighting the fire, remember that it
is better if the logs are arranged with spaces
between them to allow air flow. Finally, close
the upper door.

How do I turn off the stove?
As your stove is a safe unit it is not necessary to turn it off. However, if you wish to do so, all you
have to do is adjust the Primary Air Control to “minimum”. Remember that solid fuels react slowly, so
this process will take several minutes.
IMPORTANT
The “minimum” position on the Primary Air Control must be only used to turn off
the stove. It must never be used as a way to save firewood, as the effect will be to
make the functioning of the stove deficient.
MAINTENANCE AND CLEANING
What maintenance does my Bosca stove require?
Cleaning the flue is essential to ensure the proper functioning of your stove. This consists of removing
the creosote (a flammable substance that results from the combustion of firewood with a high per-
centage of humidity and/or when there is insufficient air entering) from the interior of the flue. This
accumulation obstructs the flue and affects the proper functioning of your stove, making the lighting
process slow and tedious and impeding appropriate combustion. Moreover, the combustion will not be
vigorous and there will be insufficent draft and an abundance of smoke emerging from the door.
IMPORTANT
Under certain conditions creosote can ignite, resulting in extremely high
and dangerous temperatures.
The frequency with which the flue must be cleaned varies according to the percentage of humidity in
the firewood you use. The flues must be cleaned at least once a year if the firewood you use is dry.
However, if it is green or contains over 25% humidity it must be done every 15 or 20 days.
