c. Extended combustion
This can be obtained:
By tripling the load at rated power (see above), composed of 1 or 2 hard wood, large
diameter and unsplit logs.
With a 6 Pa draught.
By putting the "firing rate" control in the "extended combustion" position, after having
guaranteed and maintained the firing of the load.
By letting combustion continue until a reduced bed of embers is obtained, designed
to guarantee the lighting of a new load.
This operating mode makes it possible to have reduced power and a 8 hour autonomy without
reloading.
Whatever the operating mode used (rated power or extended combustion), make sure each
load of wood lights as soon as it is placed in the appliance and that it continues to burn. If
this does not happen, open the "firing rate" control to the "lighting" position for a few moments
until the wood lights properly.
During the combustion phase of the volatile part of the wood , it is essential to avoid operation
without full fire, failing which the appliance and the chimney flue will be soiled and effluents
harmful to the environment and health will be released into the atmosphere.
Systematically use the heat resistant glove supplied with the appliance to operate the controls
which can be very hot.
d. Firing rate control
Located on the facade, this control is used to modulate the appliance firing rate between
"rated power" and "extended combustion" (control closed).
e. Lighting control
Using the firing rate control beyond the "rated firing rate" position provides additional air for
lighting. This position is reserved for lighting and re-starting operations and must not be used
for more than 30 minutes as this may cause damage to the appliance and its surroundings.
The appliance must be kept under surveillance the entire time this position is used.
f. Secondary air control
This control should remain open to its maximum for effective performance and clean
combustion. Adjusting this control is only justified if the draught is higher or lower than
recommended (see above). In that case, the control can be set to obtain performances. Once
this adaptation has been made, do not use the secondary air control. Only use the firing rate
control to vary the appliance power.
