What Kind of Chimney to Use
You must connect the Encore to a code-approved masonry
chimney with a fl ue liner, to a relined masonry chimney that
meets local codes, or to a prefabricated metal chimney.
(Fig. 3) The chimney and chimney connector must be in
good condition and kept clean.

Masonry Chimneys
An inspection of the chimney must confi rm that it has a lin-
ing. Do not use an unlined chimney. The chimney should
have no cracks, loose mortar, other signs of deterioration,
and blockage. Repair any defects before the chimney is
used with your stove.
Unused openings in an existing masonry chimney must
be sealed with masonry to the thickness of the chimney
wall, and the chimney liner should be repaired. Openings
sealed with pie plates or wallpaper are a hazard and should
be sealed with mortar or refractory cement. In the event
of a chimney fi re, fl ames and smoke may be forced out of
these unused thimbles.
The chimney should be thoroughly cleaned before use.
A newly-built masonry chimney must conform to the
standards of your local building code or, in the absence
of a local code, to a recognized national code. Masonry
chimneys must be lined, either with code-approved ma-
sonry or pre-cast refractory tiles, stainless steel pipe, or
a code-approved, “poured-in-place” liner. The chimney’s
clean-out door must seal tightly.
Prefabricated Chimneys
These should be an internal diameter of 150 mm (6”) and
be of the twin wall insulated construction that has been
approved for solid fuel use (e.g. Rite Vent ICS of ICID
Lite Chimney Systems). Diameters over 200 mm (8”) are
not recommended due to the large cross-section causing
excessive cooling of the fl ue gases.
DO NOT CONNECT THIS UNIT TO A CHIMNEY FLUE
SERVING ANOTHER APPLIANCE.
Chimney Size
An Encore with an 203 mm (8”) fl ue collar is approved for
venting into a masonry chimney with a nominal fl ue size
of 203 x 203 mm (8” x 8”) or 203 x 305 mm ( 8” x 12”), and
into a round fl ue with nominal fl ue size of 203 mm (8”).
An Encore with a 152 mm (6”) fl ue collar is approved for
venting into a masonry chimney with a nominal fl ue size of
203 x 203 mm (8” x 8”), and into a round fl ue with nominal
fl ue of 152 mm (6”).
NOTE: When installed with a 6” fl ue collar, the Encore
may not be operated with the front doors open.
Whatever the fl ue collar size, an Encore may be vented
into larger chimneys as well. However, chimneys with
liners larger than 203 x 305 mm (8” x 12”) may experience
rapid cooling of smoke and reduction in draft, especially if
the chimneys are located outside the home. These large
chimneys may need to be insulated or have their fl ues
relined for proper stove performance.
Accessories to help make the connection between stain-
less steel chimney liners and your Encore are available
through your local dealer.
Chimney Connector Guidelines
A chimney connector is the double-wall or single-wall pipe
that connects the stove to the chimney. The chimney itself
is the masonry or prefabricated structure that encloses the
fl ue. Chimney connectors are used only to connect the
stove to the chimney, as in Figure 5.
Connecting Flue Pipes
Connector pipes should meet the requirements of the build-
ing regulations. This can be achieved by the use connecting
fl uepipes included in the following categories:
a) Vitreous enamelled steel pipe complying with BS 6999:
1989 (1996);
b) Pipes made from stainless steel as descirbed in BS EN
1008-1:1995 grades 1.4401, 1.4404, 1.4432 or 1.4436 with
fl ue wall thickness of at least 1 mm;
c) Mild steel fl uepipes complying with BS 1449: Part 1:
1991, with a fl ue wall thickness of at least 3 mm;
d) Cast iron fluepipes complying with BS 41: 1973
(1998).
If you use an existing masonry chimney, it must be in-
spected to ensure it is in a safe condition before the stove is
installed. Your local professional chimney sweep, building
inspector, or fi re department offi cial will be able to inspect
the chimney or provide a referral to someone who can.
The fl ue and chimney design must meet requirement J2,
Part J of the building regulations 2000 (Combustion Appli-
ances and Fuel Storage Systems).
