Note: Long Flues: It is recommended that a support bracket is tted at least every 1 m of ue length and a
bracket must be tted at every ue joint to ensure ue seal and alignment of ue.
WARNING
Care should also be taken in the selection of ue terminals as these tend to accentuate the formation
of a plume and could freeze in cold weather conditions.

Care should be taken to ensure the specication of the chimney is suitable for the application by
reference to the manufacturers literature.
WARNING
Where single walled ues are used on the appliance, surface temperatures of the ue can reach
temperatures in excess of 80°C.
