7.9 Flue Dimensions
The standard horizontal flue kit allows for flue
lengths between 100mm and 1m from elbow to
terminal (Fig. 17).
The maximum permissible equivalent flue
length is: 4 metres.
NOTE: Each additional 45° of flue bend will
account for an equivalent flue length of 0.5m.
eg. 45° = 0.5m,
7.10 Flue Terminal Trim
1. Once the flue is secure the trim can be fitted if
required.
2. Remove the protective backing from the
adhesive seal. Apply the seal to the rear of the
trim flange (Fig. 18).
3. Locate the trim over the flue terminal and push
it back to the wall to compress the seal (Fig. 19).

between any part of the terminal and the guard.

appliance name and model number.
