Observation
Possible causes
Remedies
Poor heating with a
strong fire
- Appliance not sealed
- Excessive draft
- Check the integrity of the appliance (joints)
and connection
- Reduce the draft conditions of the flue and
in particular add a draft regulator to obtain
between 12 and 20 Pa
Too
much
heating,
combustion too fast
- Appliance overloaded with fuel
- Small diameter fuel
- Too important opening of the air for
combustion
- Load the appliance reasonably, 1 kg of dry
wood per hour for 3 kW of power. Ex. 3 kg of
dry wood per hour for a 9 kW appliance.
- Increase the diameter of the logs
- Clear the ash from the appliance less often
- Decrease the air flow of combustion
Backflow
of
smoke
through the door
- Insufficient draft conditions at nominal
operation of the appliance
- Slightly open the air inlet in order to respect
the minimum value of the operating air flow
- Take care with the use of a cooker hood or
VMC
- Check the position of the baffle
- Check the position and seal of the door
joints
The window fouls very
quickly
- Damp wood
- Slightly insufficient draft
- Operating with the primary air not
sealed
- Burn rate reduced for too long
- Use wood with a moisture level of 15 %
- Increase the level of the air inlet in the
appliance
- Increase the cross-section for the passage
of smoke by slightly opening the air inlet
- Check the position of the baffle
- Close the primary air (lever in central
position)
- Avoid reduced burn rates
The window cracks
- Shock or blow, never "slam" the door
of the insert
- The seal (between glass and door)
hardens by the use of liquid products
when cleaning the window
- Replace the window
Formation of bistre (tar)
in the flue and appliance
- Damp wood
- Flue too long
- Flue poorly insulated
- Burn rate reduced for too long
- Lack of air intake in the home
- Use wood with a moisture level of 15 %
- If possible reduce the path for the smoke,
line the flue
- Add heat insulation to the flue (ceramic
wool …)
- It is recommended using the appliance
intensely every day
- Check the air inlet level in the home
(opening of a door or window)
- Check the use of a cooker hood or
VMC
The paint flakes
- Overheating
- Sanding and repainting
- Respect the maximum loading of wood per
hour
