component, enlarging the existing ash pit of the firebox or creating it
by drilling the fire bed.
The motor housing has the dimensions: L 270 x H 170 x D 265
You must also provide space for the connection of the two air ducts
with 100 mm diameter, to be connected to the flanges (P) of the motor
housing. Insert the motor housing (M) inside the hole that has been
made in the old fire bed of the firebox.
Now, during this phase, make the air duct connections for the fan by
connecting one end of the flexible piping to the flanges (P) and the
other to the air intakes prepared previously (see next page).
Make a hole as well for the passage of the electrical wiring (N-H) that
connects the control unit (Q) to the motor and the thermostatic probe.
A compartment distant from the hot body of the insert must also
be provided to house the control unit so that it can be accessed for any
maintenance (see the “Ventilation assembly kit” section).
