Fitting the Twin Pipe (Ø80 / 80)
Note: See table for maximum and minimum ue
runs.
Where it is not possible to terminate the ue within
the distance permitted for coaxial ues, the twin
ue pipe can be used by tting a special adaptor to
the ue connector and using the aperture for the air
intake located on top of the combustion chamber.
Always ensure that the ue is adequately supported,
using one ue bracket per extension and avoiding
low points. (ARISTON supply suitable clamps as Part
No. 705778).
To utilise the air intake it is necessary to:
1) Take the air intake cover o the top of the ap-
pliance
2) Assemble the ange on the header supplied with
the boiler
3) Insert the header on the tube or the elbow up
until the lower stop (you do not have to use the
washer).
4) Insert the elbow/header in the boiler air intake
hole and fasten it with screws.
The twin ue pipes can be tted with or without ad-
ditional elbows and need no clamps, simply ensure
that the red o-ring is inserted in the female end of
the ue pipe and push the extension piece fully into
the previous section of ue pipe or elbow. Check
that the o-ring is not dislodged when assembling
the ue (greasing the seal will aid assembly).
When running the twin ue pipe vertically it can
be converted back to coaxial ue to enable vertical
termination with a coaxial kit by use the pipe bridge
(Twin - Coaxial Adaptor - Part No. 3318089).
It is not possible to terminate concentrically hori-
zontally. Termination is only possible with separate
air and exhaust terminals.
When siting the twin ue pipe, the air intake and
exhaust terminals must terminate on the same wall,
the centres of the terminals must be a minimum of
280 mm apart and the air intake must not be sited
above the exhaust terminal (refer to Fig. 10). The
air intake pipe can be run horizontally, however,
the terminal and the nal 1 metre of ue must be
installed either horizontally or with a slight fall away
from the boiler to avoid rain ingress.
It is also strongly recommended that the air intake
pipe run be constructed of insulated pipe to prevent
condense forming on the outside of the tube.
The maximum permissible ue length for twin ue
is dependent on the type of run used (see table on
page 23).
