Venting Notes
Where possible, avoid splicing
fl
ex pipes. If splices are
required, use a approved connector and seal joints with
RTV high temp sealant
.
Four feet horizontal is permissible to allow for routing
around masonry projections. Do not bend
fl
ex pipe over
a 45 degrees radius.
1. Co-linear venting may be converted to solid 4” x
6-5/8” co-axial venting at the top of the existing
solid-fuel burning chimney as necessary where
the existing chimney has deteriorated and
been removed. The conversion must be done
using approved components (see page 41) and
proper vent clearances to combustibles must be
maintained.
2. Three-inch liners may only be installed into solid-
fuel burning
fi
replaces and chimney systems (no
combustible construction).
3. The appliance must not be connected to a chimney
fl
ue serving a separate solid-fuel burning appliance.
