External air regulation
The control, via the dedicated damper (E- g. 1) located on the
external air intake, regulates the quantity of primary air neces-
sary for combustion.
Push the knob to close the external air intake; pull the knob to
open the external air intake.
OPTIONAL THERMOSTATIC VALVE (FIG. 2)
Manual adjustment of combustion air (to be carried out
during installation)
To obtain the desired water temperature, manually calibrate the
thermostatic valve.
Using the Allen supplied (X - g. 3) it is possible to regulate
the thermostatic valve using the screw located just below the
ash pan (Y - g. 3).
• Screw on RT: combustion air on minimum
• Screw all the way to the LT: combustion air on maximum
• obviously, all intermediate settings are possible
NOTE: If a thermostatic valve must be installed, you must re-
move the manual air intake damper by removing the valve and
the cable with the knob (E- g. 1).
Automatic adjustment of combustion air
The combustion air is captured by the external air intake via the
outlet (E - g. 1) and reaches the hearth through the ash grille.
This is adjusted using valve V ( g. 2).
If the temperature inside the hearth is low,compared to that set
during calibration, the valve automatically positions itself in
the open position and vice versa, it closes when the temperature
is high.
This allows the right quantity of wood to be consumed for the
set thermal comfort to be reached and unnecessary waste is
avoided.
NOTE: when the thermostatic valve fully closes the combu-
stion air inlet completely (the temperature in the hearth is very
high), limited but suf cient access is allowed for the air to
enter and keep the glass clean.

INSTRUCTIONS FOR USE
E
V
Y
Installation of thermostatic valve "V" is optional.
All operations must be performed with the thermo re-
place off and fully cooled.
The mains power must also be disconnected.
Proceed as follows:
- Open the door and block it in the open position in order
to easily work inside the hearth ( g. 4).
- Remove the following components ( g. 5):
• ash pan
• cast iron grille
• hearth base
Note: The hearth base is only on rested on the gasket,
therefore to remove it simply lift it up (keep in mind that
if the thermo replace has been used for a long period of
time there may be signi cant adhesion between hearth
base and hearth).
- Install the pre-assembled thermostatic valve on the
xing pate ( g. 6 - pg. 31).
- Secure the plate with the three screws supplied (S) to
the bottom of the hearth ( g. 7 - pg. 31).
Before xing, make sure to pass the adjustment cable and
the probe wire through the prepared slots.
- The adjustment cable must be inserted into the front
hole under the ash pan ( g. 8 - pg. 31), and secured in
position using the elastic ring supplied.
- The probe wire must be unwound along the right side of
the ash pan proceeding then to the outside of the thermo
replace ( g. 9 - pg. 31 via the hole on the right side.
- At this point insert the probe in the well on the thermo
replace (pg. 26).
- Before putting back the hearth base check the wear con-
dition of the gasket (if necessary replace it) and insert the
gasket on the perimeter of the xing plate of the thermo-
static valve ( g. 8 - pg. 31).
