•
The Chimney/Flue diameter must never be decreased in size from the stove. It is good
practise to increase the chimney/flue diameter by 25 or 50mm, this will maintain a
suitable draw in the event of the flue way becoming partially blocked due to possible
tar build up in the chimney.
•
The Chimney diameter must be no less than 125mm diameter if only burning
smokeless fuels, for any other fuel type this must be increased to a minimum of
150mm.
•
The Chimney/Flue should be kept as straight as possible. Offsets in the flue way
should be kept to a minimum and should not exceed 45 degrees except when
connecting to the rear off the stove, a 45 or 90 Degree Tee should be used for these
installations completed by a soot box at the base.
•
No more than 4x45degree elbows should be installed, when using a 90 tee at the rear
of the stove this would be classed as 2x45degree elbows.
•
90 degree elbows are not suitable for this stove.
•
When connecting the flue to the rear of the stove the maximum horizontal run should
not exceed 150mm.
•
Provision must be made for cleaning the entire length of the chimney/flue other than
through the stove.
•
The Flue way must be kept warm to ensure a suitable up draught.
