1.4 Wall Thicknesses
The standard flue assembly can accomodate the foliowing thicknesses.
Rear : from 55 mm to 576 mm
Side : from 55 mm to 392 mm
(this allows for a minimum clearance of 100 mm between the appliance and the side waii. As this dimension
increases. so the maximum side wail thickness available decreases).
Extension flue assemblies are available to accomodate wali thicknesses of:
Rear : from 577 mm to 2876 mm
Side : from 393 mm to 2692 mm
See figs. 2 and 3 for details of number of extensions required.
IMPORTANT NOTE : The extension ducts supplied, up to a maximum of 3, wili in fact permit a greater length than
indicated to be covered. The ducts MUST be cut so that the maximum length from the centre line of the flue turret to
the outermost point of the air duct DOES NOT EXCEED 3 metres horizontal. Greater length must not be used.
