Flue and Chimneys
The stove must be connected to a suitable and efficient flue so that
products of combustion (fumes) from the stove are expelled to the outside
air. Please remember that chimney draught is dependent on four main

• Flue gas temperature
• Flue height
• Flue size
• Flue terminal
To ensure a good up draught it is important that the flue gases are kept
warm and that the flue size suits the stove. The termination of the outlet
at the top of the flue also needs to comply with Building Regulations. The
