General firing tips
• The Opti-Air control system works best when the appliance is heated up as described
in section
. An Insufficient amount of fuel during ignition prevents the Opti-Air
system to work as designed, since the appliance temperature will be too low for the
Opti-Air system to reach its optimal setpoint. Refer to section
for advice on the
required fuel amount.
• Make sure the door of the appliance is closed when in use. Only open the door for
ignition and to refuel.
• Do not remove all the ashes. An ash layer in the combustion chamber forms an
insulating layer, that helps the fuel to ignite easy.
• After the first load, do not overload the appliance with fuel. Refer to section
the recommended amount of fuel. The Opti-Air system prevents the appliance to
reach an excessive high temperature, but a large overload can cause excessive
emissions and loss of efficiency.
