Minimum reading: The appliance should be lit and allowed to warm
the flue thoroughly. Close the air slider control and ensure firebox
door is fully closed. Allow the burning rate to become steady. The
flue draught reading should now be taken; the minimum required is
12 Pascal’s [Pa] (0.05’’ wg.).
Maximum reading: The air slider controls can now be opened to
allow the appliance to burn at maximum rate. Keep the flue box
door closed. Take a flue draught reading.
Ideally, the flue draught readings should range between 12Pa,
0.12mm (0.05’’ wg.) and 24Pa, 2.5mm (0.1’’ wg.). Any readings
significantly outside this range may indicate the need for remedial
action. Low flue draught symptoms: difficult to light and smoke
coming into the room. With a high flue draught, fuel burns away
very quickly.
Flue Stabiliser
A flue stabiliser can be fitted to reduce the draught through the
appliance if the draught is too high. The flue stabiliser should be
fitted in the same room as the appliance and be the same size as
the flue pipe. (Note: extra ventilation will be required as stated in
the Building Regulations.
SOLID FUEL BURNING
Before attempting to burn solid fuel using the solid fuel
grate and ashpan assembly (these must be ordered
separately)
the catalysers and their holding bracket
must be removed
. Your cooker is fitted with two
catalytic converters under the hotplate on the right
hand side. The function of these catalysers is to improve
the quality of the smoke emissions.
Fitting the solid fuel burning kit will reduce the output
to water.
