exhaust blower operation (failure), reducing the probability of burn-back
and back-drafting.
Check that the connection to the flueway is gas/smoke-tight,
since the appliance operates in a vacuum.

If you wish to use an existing chimney it is strongly recommended that
you have it checked by a professional chimney sweep to ensure that
it is completely airtight (Fig. 12). The reason for this is that the
smoke, because it is slightly pressurized, can infiltrate any cracks
in the flue and escape into living spaces. If upon inspection you
find that the chimney is not completely sound, a relining of the
chimney with either PL vent or single wall stainless steel pipe may
be necessary to bring the chimney into compliance. If the existing
chimney is wide enough we recommend a pipe with a maximum
diameterof6”.
Put attention: some areas require that a liner must be always installed
to the top of the flue, as shown in figure even if the existing chimney
is in compliance (Fig. 13).
•
When chimneys are relined, a chimney chase cap that reduces the
outlet of the chimney to the size of the liner is required. Extend the
exhaust vent above the chimney chase cap and finish it off with a
raincap.

Outside Chimneys frequently are difficult to keep warm: it is
recommended that you insulate the liner.
•
Venting into the side of an existing masonry chimney must be done
through a masonry thimble. When wall penetration is necessary to
access a masonry chimney, use a listed PL vent wall thimble (Fig.
12-13).
•
WhenventingintoaClassAsteelchimney,(Fig.14),useanappropriate
PL Vent adapter.
Strictly observe the PL Vent manufacturer’s safety
specifications.
INSTALL VENT AT CLEARANCES SPECIFIED BY THE VENT
MANUFACTURER.
Ensure that all installation work is carried out to professional
standards.
