FLUE INSTALLATION
MEASURING THE FLUE (Extension Flue Kits):
ONLY CUT EXTENDED FLUE LENGTHS
As with the Standard Flue measure from the outside wall to the centre line of the flue turret.
Subtract the length of the Standard Flue and turret (725mm) from length L . Subtract the full length 1m extension(s) from the figure.
Cut one of the 1m extensions to the remainder. Cut both tubes square taking care not to distort the tubes.
Remove any burrs.

When flue bends are being used an allowance of 98mm per bend must be allowed from the centre line of the bend. In the example shown using a flue extension with 2 bends will achieve a total length of 1148mm.
