Once the boiler has been positioned on the wall, it is ne-
cessary to insert the Ø80/125 adaptor (Fig. 5) for both
horizontal and vertical ue runs into the boiler ue soc-
ket (not supplied with ue kit - Part No 3318095).
Push the adaptor onto the boiler’s ue connection,
grease the seals then add extensions or elbows as re-
quired, secure the adaptor, using the clamp and screws
provided.
To t extensions or elbows it is rst necessary to en-
sure that the lip seal is tted correctly into the inner
ue, once veried, it is simply necessary to push them
together, no clamps are necessary to secure the ue
components.
Before proceeding to t the ue, ensure that the ma-
ximum ue length has not been exceeded (See the
tables) and that all elbows and bends have been taken
into consideration, the maximum ue length is 10
metres, for each additional 90° elbow 1 metre must
be subtracted from the total ue length, and for each
45° bend 0.5 metres must be subtracted from the total
ue length (the height of the vertical adaptor and a 45°
bend can be seen in Fig.6 and a 90° bend in Fig. 7).
Note: DO NOT cut the vertical ue kit.
