Damage to the appliance
Debris entering the appliance
▶ Do not install the flue duct with the open end facing up the chimney
The horizontal flue pipe connecting appliance and flexible liner must rise
by at least 52mm for every metre of length. This is to ensure the
condensate flows back into the appliance.
▶ The lower edge of the chimney opening is higher than the appliance.
As shown in fig. 6, the height h is dependant on the distance d . For every
metre the appliance is away from the chimney wall the height must rise
by at least 52mm. The further away the appliance stands from the
chimney wall, the higher the lower edge of the chimney hole must be.
Fig. 6 Positioning the chimney opening
The chimney hole must be large enough to install the flue and allow
access to the joints for servicing.
▶ Make an opening in the chimney wall according to the measurements
shown in table 13.
▶ Mark the position of elbow support, ensuring that the mark is centred
within the opening made in the chimney wall.
▶ Drill a Ø 10mm hole 60mm deep into the chimney wall.
