Permitted reduction:
- flue Ø150
reduction not permitted
- flue Ø180
maximum reduction 30 mm
- flue Ø200
maximum reduction 20 mm
- flue Ø250
maximum reduction 50 mm
After reducing the flue, it is no longer possible to use the
Pure as an open fire place.
Reduction is permitted immediately behind the damper
connection collar, but not any deeper into the flue. At doubt,
always use the connection diameter indicated on the Heat Pure.
•
Avoid horizontal runs; one extension may be placed with
adjustable elbows with maximum one change of direction of
45°.
•
Kal-fire advises you to insulate the flue; this will reduce the
risk of the smoke condensing and will improve the draught.
Use the Kal-fire stainless steel insulated flue duct for this
purpose.
•
Kal-fire advises you not to use larger flue diameters than the
connection present on the Heat Pure. Using a larger flue
diameter can result in the following problems:
-
-
-
Too fast and uncontrolled combustion;
Irregular flames;
Reduced heat output.
•
Use a draught hood if there is a flue with a (too) strong
draught. If the flue has too much upward draught, this may
result in a too quick, uncontrolled combustion, irregular
flames and rapid soiling of the glass door.
•
Use of different flue diameters to those indicated, is entirely
for the risk of the installer; when the door is opened, smoke
may escape back into the room or it may be more difficult to
ignite the Heat Pure.
•
Take factors in the surrounding environment into acc
which could cause a strong draught in the flue. For example,
frequent high winds, which require a damper
•
Pay attention that it is also possible to sweep the chimney in
the connection piece.
