Operation Manual

The stove may be connected to an existing Class A chimney or a masonry
chimney which meets the minimum requirements of NFPA 211. Using
this kind of installation the pellet stove is able to draft naturally without
exhaust blower operation (failure), reducing the probability of burn-back
and back-drafting.
a Check that the connection to the ueway 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 chimneysweep to ensure that it
is completely airtight (Fig. 12). The reason for this is that the smoke,
because it is slightly pressurised, can inltrate any cracks in the ue
and escape into living spaces. If upon inspection you nd 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 diameter of 6”.
Put attention: some areas require that a liner must be always installed
to the top of the ue, as shown in gure 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 nish it off with a
rain cap. A single wall liner may need to be insulated to maintain
adequate exhaust temperatures in the vent system.
a Outside Chimneys frequently are difcult 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).
• When venting into a Class A steel chimney, (Fig. 14), use an appropriate
PL Vent adapter.
a Strictly observe the PL Vent manufacturer’s safety
specications.
a INSTALL VENT AT CLEARANCES SPECIFIED BY THE VENT
MANUFACTURER.
a Ensure that all installation work is carried out to professional
standards.
