Fitting the Horizontal Flue
The instructions for the installation of the elevated horizontal,
concentric vertical, biflux (twin pipe) and SE duct flue options
are included with the relevant adapter kits.
The horizontal standard flue supplied with the appliance is
suitable for lengths from 300 mm minimum to 610 mm
maximum. This means for rear flueing, the standard kit will
accommodate a maximum wall thickness of 490 mm, and for
side flueing a maximum wall thickness of 477 mm. This takes
into account the minimum appliance side clearances of 5 mm.
If the fixing is a rear exit flue, the template provides the
position of the centre for drilling the flue hole with a core drill.
If the flue is a side exit installation then calculate the position
of the hole with a slope, away from the boiler, of 5 mm / metre
to the terminal.
