FLUE RESTRICTOR
A flue r
estrictor (47 mm Ø NG, 43 mm Ø propane) is supplied with the
appliance for use only if the horizontal flue length does not exceed 620
mm, if a vertical flue is fitted refer to supplement 1 for further guidance
on the use of flue restrictors.
If any extensions 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 r
estrictor 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 r
estrictor ring inside the flue elbow bottom as shown in figure
25 ensuring that it is the correct way round.
NOTES
1)
Failing to fit the r
estrictor when installing the appliance with a
standard flue system will not provide optimum performance.
2)
Fitting the r
estrictor on horizontal flue system incorporating
extensions or additional bends and fitting a restrictor on
vertical flues greater than 2300 mm will adversely affect
performance and may constitute a safety hazard.
3)
Failur
e to comply with these instructions will invalidate the appliance
Certification and therefore may contravene the appropriate EC
legislation and local statutory requirements.
