FIG. 18 FLUE ELBOW EXTENSION
When side fluing, slide the elbow extension onto the elbow,
push on fully and align the hole for securing screw with
arrow on elbow. Engage the screw from accessory pack 'C'
into the pre-drilled hole in elbow extension and screw fully
home. The screw which is self drilling will pierce the elbow
and secure the extension to the elbow.
When rear fluing, the elbow extension should be discarded.
FIG. 20 PIPE CONNECTIONS
Connect system pipework to the boiler, compression
fittings should be used. If however capillary fittings are
used it is essential to temporarily remove both of the
thermostat bulbs from the flow pipe before soldering.
FIG 19 LOCATION OF PRESSURE SENSING TUBES
Slide the flue elbow into the duct, ensure that the sealing
gasket is in place and the elbow is correctly located
beneath the retaining flange at the rear See FIG 19
Secure elbow using thumb screw previously removed.
Reconnect flexible tubes to elbow.
ENSURE THEY ARE NOT KINKED.
The tubes are supplied at the length required for left hand
flue outlet. When using rear or right hand flue outlets, to
avoid kinking, the tubes should be shortened by 150mm. A
band around the tube indicates the cutting point.
NOTE
Red tube connects the front aluminium tube to the lower
connection on the elbow, each being identified with a red
ring.
A drain off tap should be installed close to the boiler if it is
in a low point of the system. Connect the gas supply pipe
to the inlet of the gas cock. Ensure the gas cock is in a
position where it can be easily operated when the controls
cover is removed.
