Connecting To A Conventional Chimney - Piazzetta P962 Instructions For Installation, Use And Maintenance Manual

1.10 CONNECTING TO A CONVENTIONAL CHIMNEY - Fig. 21 - 22
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 infiltrate any cracks in the flue and escape
into living spaces. If upon inspection you find 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 150 mm. It is also recommended that
you insulate the chimney flue (Fig. 21-22).
Pipes and bends made by Gruppo Piazzetta S.p.A. are recommended
for connection to the flueway, since they are sized to fit the flue 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, Gruppo Piazzetta S.p.A. only guarantees trouble-free
operation for parts that it manufactures and that are used according to
specifications.
Connection to the flue must respect the 40 cm minimum safety
distance from heat-sensitive structural components or inflammable
materials (wood panelling, beams or ceilings, etc). (See figures 17-18).
- If the connector has to pass through partitions or walls of inflammable
or heat-sensitive materials, or through load-bearing walls, create:
an insulating barrier equal to or greater than 10 cm around the
connector using mineral-based insulating material (rock wool,
ceramic fibre) with a nominal density greater than 80 kg/m
- If the connector has to pass through non-flammable partitions or
walls, create:
an insulating barrier equal to or greater than 5 cm around the
connector using mineral-based insulating material (rock wool,
ceramic fibre) with a nominal density greater than 80 kg/m
- Check that the connection to the flueway is gas/smoke-tight, since
the appliance operates in a vacuum.
- Check that the pipe does not penetrate too far into the flueway,
thereby choking the pipe for the passage of smoke and combustion
gases.
Ensure that all installation work is carried out to professional
standards.
