INSTRUCTIONS
BAXI recommends permanent connection of a BAXI buffer tank (see Section 4.3):
– The boiler will always be able to discharge its heat.
– Better combustion, less depositing of soot and tar, longer boiler life.
– Simpler operation as the filling chamber can be completely filled.
– The boiler can be fired when you have time and the house can be supplied with
heating as required from the buffer tank.
3
– Hot tap water from a container in the buffer tank (BAXI will be happy to assist
with calculating the buffer tank size).
– The amount of wood placed in the boiler's filling chamber depends on the size
4
and the temperature of the buffer tank. The boiler should not be fired beyond the
reservoir's heat storage capacity.
– Do not add wood until the temperature in the buffer tank has fallen to 40-50°C so
that the reservoir will again be able to absorb heat.
– Set the boiler temperature to 90°C, i.e. almost maximum.
– Clean the boiler regularly (see Section 1.7).

Too little air.
Flame too long and reddish yellow.
Increase secondary air.
The Solo Innova features primary and secondary air combustion
for optimal burning.
Combustion is controlled with primary air adjustment 3 and
secondary air adjustment 4. Both are normally 75% open*).
Combustion is stable after about 45 minutes of operation and the
secondary air may be turned off.
Observe the combustion through the sight glass 6.
The flame should be yellow and pale bluish, and the flame length
should be appropriate (see below).
It is normally only necessary to adjust the setting if the fuel is
changed.
*)If full output is required, they can be opened 100%.
