OPERATING INSTRUCTIONS
AIR SETTINGS
Th
e high output (when there is a heat demand) is set in the factory at 1
1/2” and should only be altered by the installer. Th
e low output (standby)
can be adjusted with the screw on the primary air blade (see fi g 25)
situated underneath the loading door. It controls the gap
“A”
. Th
e bigger
the gap, the more combustion air enters into the fi rebox, the higher the low
burn.
Every installation is diff erent because of draft , kind of wood being used
and geographic location. Adjust the fl ap in a way that it maintains a fi re
