Setting The Air Control Management
The following is a recommendation only for maximum efficiency.
When burning wood only or solid mineral fuels (smokeless fuels) the following settings are
recommendations only as it is all dependent on the moisture content of the material to be
burnt.
So if the moisture content is above 16 to 20% which is the recommended level in any of
these products you may well need to make adjustments to get the optimum burn efficiency
out of this stove. So the following is a guide only to the position of the primary secondary and
tertiary air controls.
Please note that wood burns from the top of the fire box down so more control is gained from
the secondary and tertiary slider control bar. This slider operates the clean glass air wash
system which assists in helping to prevent the glass blackening up. It also operates the Eco-
Cleanburn at the rear of the fire box which helps to insure that all of the gases given off from
the wood and solid mineral fuels are fully burnt prior to being exhausted up the chimney,
therefore giving maximum heat output and efficiency to the stove.
As you open and close the left hand slider (Fig. 2) for the clean glass air wash (secondary)
and the Eco-Cleanburn (tertiary) there is a balancing valve (which you never need to touch)
fitted into the rear of the stove that automatically manages the volume of air being fed to each
of the outlet air controls so the optimum airflow is delivered to the clean glass air wash down
the front of the glass and the Eco-Cleanburn afterburn at the rear of the fire box.
However, solid mineral fuels burn from the bottom up so you require air flow from the right
hand slider (Fig. 1) and less from the secondary and tertiary control.
Please refer to the table below as a guide only to the position of the 2 air controllers. Also
note the required riddle grate position for each type of fuel. To change the riddle grate position
insert handle (see Fig. 4), then push backwards to close the grate or pull forward to open the
grate.
