4.11.14 Checking System Pressure
The system expansion tank in a closed system allows for the thermal expansion of the fluid in the
heating system. See the expansion tank’s operating instructions for maintenance requirements.
4.11.15 Heat Storage System Maintenance
As described above, the Solo Innova boiler needs to be installed with a thermal storage system or
other heat storage system. Please follow the recommended maintenance schedule for these parts of
the heating system. Specific maintenance items for the heat buffer will be specified by the system
manufacturer, but items may include checking any safety valves, anode in any connected hot water
reservoir, or system water level and system PH in static water storage systems.
4.12 Power Outages
The boiler will not operate in the event of a power failure. Do not open the loading or ash doors until
power is reestablished. The fan needs to be able to operate to remove combustible gasses. It is good
practice to close the primary and secondary air dampers (move the dials counter-clockwise to first
position). Remember to open the dampers before the next firing.

PROBLEM
ROOT CAUSE
Solution
No
Heat
in the System
Thermostat (I) set too low
Set Thermostat higher
Fan cut out because the min. thermostat temperature
has fallen below 90
°
C (194
º
F).
Press Reset Switch (N)
Overheat thermostat triggered
Reset thermostat
Termovar (Mixing Valve) is closed or defective
Check valve for proper operation
Check balancing valve for proper posi-
tion which is half open
Circulator pump is not running
Switch on or replace pump
Insufficient water in the system
Add water to the system Note: Never
add water to an overheated boiler.
Wait until the boiler has cooled down
Air in the system
Bleed air from system
Fuse (D) is blown
Replace fuse in boiler control
Combustion will not stop
Excessive chimney draft
Have a serviceman install a draft
regulator
Loss of pressure in the system
Bleed the system and add water
The fan does not switch off
when the fire burns out
If the boiler is operated from cold, the flue gas tempera-
ture must reach normal operating temperature (above
90
°
C (194
º
F)) to switch over the min. thermostat. If
normal operating temperature is not reached, the fan will
not switch off but continue to run, even though the wood
has burned out and the min. thermostat temperature has
fallen below 90
°
C (194
º
F).
Ensure that the boiler is brought to
normal operating temperature (about
85-90
°
C (185-194
º
F)) each time it is
used.
