Pipes and maximum usable lengths
Pipes of painted aluminium-clad steel (minimum thickness 1.5mm), stainless
steel (AISI 316) or enamelled steel (minimum thickness 0.5mm) with a
nominal diameter of 80 or 100 mm (for pipes which run inside the fl ue
maximum diameter 150 mm) can be used.
The male-female connectors must have a minimum length of 50 mm.
The diameter of the pipes depends on the type of installation. The stove was
designed to take 80 mm diameter pipes but, as shown in Table 1, in some
cases the use of double-lined 100 mm diameter pipes is recommended.

If you wish to use an existing chimney it is strongly recommended that
you have it checked by a professional chimneysweep to ensure that it is
completely airtight. The reason for this is that the smoke, because it is
slightly pressurised, can infi ltrate any cracks in the fl ue and escape into
living spaces. If upon inspection you fi nd that the chimney is not completely
sound, it is recommended that you insert piping made of new material. If the
existing chimney is wide enough we recommend a pipe with a maximum
diameter of 150mm. It is also recommended that you insulate the chimney
fl ue (Fig. 21 - 22).
Pipes and bends made by the factory are recommended for connection to the
fl ueway, since they are sized to fi t the fl ue outlet of the appliance.
Other pipes may be applied after adaptation and checking of the compatibility
of the coupling, taking into account that the pipes and bends must be made
in compliance with current regulations. In this case, however, the factory only
guarantees trouble-free operation for parts that it manufactures and that are
used according to specifi cations.

Losses in pressure associated with a 90° bend can be compared to those incurred by one metre of pipe. An inspectable union-tee can be
considered equivalent to a 90° bend.
EXAMPLE:
if installing a section greater than 4.5m in length with 80mm diameter pipe, calculate the maximum usable length in the following ways:
- If a maximum of
three 90° bends
are used, the maximum length of the section will be
4.5m
.
- If a maximum of
two 90° bends
are used and bearing in mind that a 90° bend can be replaced by one metre of pipe, the maximum length of the section
will be
4.5m+1m=5.5m
.
- If a maximum of one 90° bend is used and bearing in mind that a 90° bend can be replaced by one metre of pipe, the maximum length of the section
will be
4.5m+1m+1m=6.5m.
Where 100mm diameter pipe must be used, connect it to the stove fl ue outlet with a 80mm union-tee then use a 80mm 100mm adaptor (not supplied by
Superior) (Fig. 19).
Union-tee
The use of this type of fi tting must allow for the collection of condensate mixed with soot, which builds up inside the pipe. It must also permit periodic
cleaning of the fl ue without the need to disassemble the pipes. This type of fi tting can be bought at Superior retail outlets together with the pipes. An example
is given below of a fl ueway connection, which allows complete cleaning without having to disassemble the pipes (Fig 20).
