7.3 Chimney and flue pipes
The flue pipe’s dimensions and quality must comply with the local applicable regulations prior to
connecting the stove to the flue pipe. Therefore the dimensions must be calculated properly.
We guarantee the proper functioning of the appliance if the chimney draught is at least 12 Pa. If
the chimney draught is too high, a draught regulator must be built into the chimney.
If there isn’t enough chimney draught, then the f
ollowing measures can be considered:
•
Extending the chimney
•
Improving the insulation of the chimney (less cooling of the flue gases)
•
Increasing the supply of combustion air into the space in which the appliance is installed.
•
Improving the airtightness of the chimney
Many problems with inset fires are caused by badly working chimneys. Therefore some
suggestions:
•
A round channel is preferred (minimum friction)
•
The diameter of the chimney may not be smaller at any point than that of the appliance
•
The mouth of the chimney should be unobstructed
•
The chimney should be as close as possible to vertical with as few curves as possible.
Carrying is possible only when the angles are up to 45 degrees.
•
The chimney must not draw in extra air. Watch out for flue dampers and cleaning hatches in
the cellar or on the roof!
•
The chimney may not have too many connections - that reduces the upwards pressure.
Consult your chimney specialist!
•
Flue connections to different stoves and fireplaces may not be located opposite each other at
the same height, in order to prevent the chance that combustion gases will not be drawn out.
Two flue connections must be at separated vertically by at least 30 cm.
For details on chimneys we refer you to the relevant regulations with which the chimney needs to
comply.
7.4 Connection of the stove to the chimney
The stove can be connected directly to the chimney (rear connection).
The diameter of the chimney should match the diameter of the flue outlet of the appliance., Please
note the following regarding the diameter of the chimney:
•
The diameter of the chimney may not be reduced. Also, the flue outlet must fit the chimney
perfectly.
•
If there is too much chimney draught, then a damper must be incorporated.
•
The chimney may not draw in extra air. Watch out for flue dampers and cleaning hatches in the
cellar or on the roof!
•
The flue outlet must be securely attached to the connector pipe.
