4.7.2
FLUE RESTRICTOR
A flue restrictor is supplied with the appliance for use, only
if no extensions or additional flue extension elbows are
fitted.
If any extension ducts or additional elbows etc are to be used,
proceed to section 4.7.3.
If only the standard flue components (i.e. those packed in the same
carton as the appliance) are to be used fit the restrictor as follows:
a) ) Note the position of the flue restrictor ring. This is fitted on top
of the appliance and is secured by the air pressure switch
bracket screws (Fig. 24). Loosen the air pressure switch screw
by 1/2 turn only, to release the ring, and tighten the two screws.
b) Fit the restrictor ring inside the flue elbow bottom as shown in
figure 25 ensuring that it is the correct way round.
NOTES
(i) Failing to fit the restrictor when installing the appliance with a
standard flue system will not provide optimum appliance performance.
(iii) Fitting the restrictor on a flue system incorporating extensions
or additional bends will adversely affect performance and

Wall thickness up to 800 mm (31in) only.
a) Push the terminal through the wall liner taking care to ensure that
the terminal is the correct way round and the external wall sealing
ring does not become dislodged.
b) Pull the flue system towards the boiler to seat the external sealing
ring against the outside wall and secure the elbow to the boiler
using the four screws provided.
c) Finally use the internal sealing ring to make good the internal
hole, and check that the terminal is correctly located on the
outside wall (Where possible this should be visually checked
from outside the building).
Figure 26 shows a view of the flue system correctly installed.
d) Assemble as shown in Figure 26.
