Encore

®

 1450CE Non-Catalytic Woodburning Stove

what kind of chimney to use

You must connect the Encore to a code-approved 
masonry chimney with a flue liner, to a relined masonry 
chimney that meets local codes, or to a prefabricated 
metal chimney. The chimney and chimney connector 
must be in good condition and kept clean.
If you use an existing masonry chimney, it must be 
inspected to ensure it is in a safe condition before 
the stove is installed. Your local professional chimney 
sweep, building inspector, or fire department official will 
be able to inspect the chimney or provide a referral to 
someone who can.
The flue and chimney design must meet requirement 
J, Part J of the building regulations 000 (Combustion 
Appliances and Fuel Storage Systems).

masonry chimneys

An inspection of the chimney must confirm that it has 
a lining. 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.  Open-
ings sealed with pie plates or wallpaper are a hazard 
and should be sealed with mortar or refractory cement. 
In the event of a chimney fire, flames 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 
masonry 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 00 mm 
(8”) are not recommended due to the large cross-sec-
tion causing excessive cooling of the flue gases.

chimney Size

An Encore with an 03 mm (8”) flue collar is approved 
for venting into a masonry chimney with a nominal flue 
size of 03 x 03 mm (8” x 8”) or 03 x 305 mm (8” 
x 1”), and into a round flue with nominal flue size of 
03 mm (8”). An Encore with a 15 mm (6”) flue collar 
is approved for venting into a masonry chimney with a 
nominal flue size of 03 x 03 mm (8” x 8”), and into a 
round flue with nominal flue of 15 mm (6”). 

Note:  when installed with a 152 mm (6”) flue col-
lar, the encore may not be operated with the front 
doors open.

Whatever the flue collar size, an Encore may be vented 
into  larger chimneys as well.  However, chimneys 
with liners larger than 03 x 305 mm (8” x 1”) 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 flues relined for proper stove performance.  
Accessories to help make the connection between 
stainless 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 chim-
ney itself is the masonry or prefabricated structure that 
encloses the flue. 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 
building regulations. This can be achieved by the use 
connecting fluepipes included in the following catego-
ries:
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, 1.443 or 
1.4436 with flue wall thickness of at least 1 mm; 
c) Mild steel fluepipes complying with BS 1449: Part 1: 
1991, with a flue wall thickness of at least 3 mm;
d) Cast iron fluepipes complying with BS 41: 1973 
(1998).
