Flue
The minimum flue draught required for nominal heat output is 12 Pascals. At nominal heat output
the flue gas temperature will be in the region of 262°C. The appliance should not be connected to a
shared flue. The design of the flue installation should allow access for sweeping.
The stove has both rear and top flue connections. The figure on the right shows the flue connection
options. Seal the flue connections with fire cement or a high temperature rope seal. The flue
blanking plate should be positioned over whichever outlet is not being used.
Figure 5 below shows a typical installation for which you would need:
A register plate – this plate is used to seal off the throat of the fireplace and has a hole for
the flue pipe, access for sweeping and if required a bracket to support the flue.
The 6” (150mm) flue pipe required from the stove to the register plate.
Operational Problems
Blackened Glass
The wood is too damp. Only use wood that has been stored for at least 12 months under
cover and ideally with a moisture content less than 20%
Insufficient intake of air from the air control. Open the air control further.
Insufficient ventilation
The stove is being run at too low a temperature
Smoke in the room when refuelling
Poor chimney performance – consult chimney sweep or Installation engineer
Check the position of any fitted flue damper to make sure it is in the open position
Never open the door when there are high flames on the wood
Uncontrollable Combustion
Damaged door seal. Fit new seal
If there is excessive chimney draft – fit a draft stabiliser in the flue pipe – consult a
chimney sweep or the Installation engineer
