TROUBLE SHOOTING
Causes - Advice
Observations
Possible reason
Advice
Lighting-up difficulties
- Wet wood
- Logs too large
- Cold flue
- Draft not sufficient
- Use small and dry wood to form a bed of embers
- Reheat the flue by lightingnewspaper, door closed
- Check the operating conditions of the flue and the air intake level in the
home
- Test the draft with a depressionmeter
Smoke backdraft
- Insufficient draft
- Effect of wind
- Poorly insulated flue
- Flue too short
- Flue not sealed
- Flue cross-section too small
- Flue partly obstructed by a foreign
body of tar
- Presence of a too powerfull V.M.C
or cooker extraction hood
- During the opening of the door
- Consult the installer
- Draft test with a depression meter
- Inspect the flue and sweep if necessary
- Review the air intake level of the home (check the opening of a door or
window)
- Place the house und a slight overpressure
- Open the air inlet before opening the door
- Always open the door slowly in order to avoid smoke being sucked
outside the fireplace
Little heating, the fire does not take
well during normal operation
- Insufficient draft
Little heating, the fire does not take well during normal operation
Chimney fire
- Sweep chimney oversight
- Respect the normal occurrence of chimney sweeping
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 pf 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
