Operation
7.4.4
General firing tips
•
The Opti-Air control system works best when the appliance is heated up as described
in section 7.4.2. 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
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.
