No.
1. No heat in the system
2. Combustion will not stop.

If combustion continues despite switching off the fan at the
thermostat (I) or the switch (F), the problem may be an excessive
chimney draught.
Bleed the system and add water.
(See Section 1.6 Maintenance)
If the boiler is operated from cold, the boiler temperature must
reach normal operating temperature (above 80°C) 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.
What causes poor boiler performance and why doesn't the flame length in the fuel
tunnel change when the adjustment for secondary air is changed?
It is important to use wood of an appropriate size (length and diameter) and to stack it
properly so that there are no "holes" and "hanging pieces" in the wood stack, which
must then be regularly stirred with the poker to form it into a compact mass.
The diameter of the wood may not exceed 10-12 cm as "holes" would then form more
easily in the wood layer, creating a risk of reduced heating output. Thick pieces of wood
must be split to a diameter of 10-12 cm.
See Section 1.3.13 for correct flame length.
possible solution
Thermostat (I) set too low.
Set thermostat higher.
Fan cut out because the min. thermostat temperature
has fallen below 90°C.
Press reset switch (N).
Overheating thermostat triggered.
Press knob in again.
Mixer (if present) fully or partly closed.
Open.
Circulation pump not running.
Switch on.
Insufficient water in the system; air in the system.
Top up and bleed.
Never add water to an overheated boiler.
Wait until the boiler has cooled down.
Regulator may have switched off the system.
See user guide for regulator.
Fuse (D) blown.
Replace fuse in boiler control
(see Fig. 1.4.1).
Call a serviceman if you cannot determine the cause.
If this is the cause, a draught limiter should be built into the
chimney. Consult your serviceman and chimney sweep about
purchase and installation (see Section 3.3.3).
Call a serviceman if the pressure continues to fall.
Ensure that the boiler is brought to normal operating
temperature (about 85-90°C) each time it is used.
