11a Horizontal Top Flue Installation
The Horizontal Top Flue , Kit No. 86285H is
suitable for installations that require a flue
length from 190 minimum to 667 maximum
(without extensions). If a shorter flue length is
required the flue can be cut to suit, see
diagrams 11a.1 and 11a.2 for minimum flue
length.
Note: Additional 1 metre extentions, 90° and 45° bends are
available. The maximum extended flue is 3.5m. The use of flue
bends requires the flue lengths to be reduced by 1m. for 90° and
0.5m. for 45°.
11a.1 Top outlet flue - kit 86285H
The boiler is only suitable for top outlet flue connection.
11a.2 Rear flue systems
(Refer to diagram 11a.1). To calculate the length when flueing
to the rear measure wall thickness e plus 140 mm for the outer
air duct and e plus 231 mm for the inner flue duct measurement.
11a.3 To The Right or Left flue systems
(Refer to diagram 11a.1). To calculate the length when flueing
For right hand applications measure wall thickness e plus
inside of wall to side of boiler a add 350(mm) for the outer air
duct and wall thickness e plus inside of wall to side of boiler a
add 445(mm) for the inner flue duct measurement.
(Refer to diagram 11a.1). To calculate the length when flueing
For left hand applications measure wall thickness e plus
inside of wall to side of boiler a minus 25(mm) for the outer air
duct and wall thickness e plus inside of wall to side of boiler a
add 70(mm) for the inner flue duct measurement.
• Refer to diagram 11a.2 (table) for cutting lengths of both inner
and outer flue pipes for each of the various flue options
available.
Important: All flue cutting lengths must be measured from the
terminal end of the flue pipes, see diagram 11a.2.
When the dimension X measured on site is greater than that
given in diagram 11a.2 (table), extensions will be required as
necessary.
Important: All cutting lengths should be measured from the
push fit joint end of the extension pipe. Do not leave any burrs
or sharp edges on the cut ends of the pipes. Note : maximum
horizontal flue length without bends is 3 m.
