Worcester C1 User Manual

The flue system must be installed following the requirements of
BS5440: 1.
Standard flue kit length is 330 - 725mm (as measured from the
centre of the flue turret) with extension kits for flues up to
2975mm measured from the central line of the flue turret.
The terminal must not cause an obstruction or the combustion
products a nuisance.
Under some conditions the terminal might steam and positions
where this might be a nuisance should be avoided. Refer to Fig 7
If the terminal is less than 2m above a surface to which people
have access then a guard must be fitted. The guard must be
evenly spaced about the terminal and fixed with plated screws.
A Type K2 guard is available from Tower Flue Components, Vale
Rise, Tonbridge, TN9 1TB.
