8.0 Installation
8.6 Fitting the Flue (Cont)
IMPORTANT: If the equivalent flue length is greater
than 1.5m the restrictor MUST be removed from
the adaptor (Fig. 22).
8. Take one of the rubber seals and position it on the
boiler flue adaptor. Engage the flue elbow on the adaptor
and pull the sleeve up so that it equally covers the joint
(Fig. 22).
9. Remove the screws from one of the clips provided.
Prise the clip apart and fit it over the seal (Fig. 23). Set
the elbow to the required angle.
10. Refit the screws to the clip and tighten them to
secure the elbow. Take the second rubber seal and
position it on the flue elbow.
11. Locate the flue duct clamp on the flue outlet elbow.
Draw the flue duct out of the air duct, engage it in the
clamp and tighten the screws (Fig. 24).
12. Draw the air duct out of the wall and align it with the
elbow. Position the seal so that it equally covers the joint
(Fig. 25).
13. Remove the screws from the second clip provided.
Prise the clip apart and fit it over the seal. Refit the
screws to the clip and tighten them (Fig. 25).
14. Where possible position the clips so that the screws
are not visible.
15. Make good between the wall and air duct outside the
building.
16. Fit the circular flue trim outside if required, and if
necessary fit a terminal guard (see Section 7.10 & 7.11).
8.7 Extensions & Additional Elbows
1. The method of connecting any flue extensions or
additional elbows is the same as that for connecting the
standard flue and 90° elbow as described above.
2. If, for example, when a flue extension is connected to
a 90° elbow the flue duct will project from the air duct at
the unconnected end by the same amount as the flue
duct spigot does from the elbow . Further elbows or
extensions can then be added to this.
3. Similarly, a concentric flue can be connected to the
boiler adaptor in the same manner as it does to the
elbow to provide a vertical flue.
4. The additional 90° elbow available is identical to the
elbow supplied with the standard flue. 45° elbows are of
the same principle.
5. Extensions can be cut according to the requirements
of the installation.
