Defiant 1610CE Non-Catalytic Woodburning Stove
30003846
What Kind of Chimney to Use
You must connect the Defiant 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. Figure 3 illustrates the two types. The
chimney and chimney connector must be in good condi-
tion 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 refer-
ral to someone who can. See “Chimney and Fireplace
hazards”, in the appendix, for particulars.
The flue and chimney design must meet requirement
J2, Part J of the building regulations 2000 (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. A loose or
leaky clean-out door can weaken chimney draft, caus-
ing performance problems.
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-sec-
tion causing excessive cooling of the flue gases.
DO NOT CONNECT THIS UNIT TO A CHIMNEY FLUE
SERVING ANOTHER APPLIANCE.
Chimney Size
A Defiant with an 203 mm (8”) flue collar is approved
for venting into a masonry chimney with a nominal flue
size of 203 x 203 mm (8” x 8”) or 203 x 305 mm (8” x
12”), and into a round flue with nominal flue size of 203
mm (8”). A Defiant with a 152 mm (6”) flue connector
is approved for venting into a masonry chimney with a
nominal flue size of 203 x 203 mm (8” x 8”), and into a
round flue with nominal flue of 152 mm (6”).
NOTE: When installed with a 152 mm (6”) flue col
-
lar, the Defiant may not be operated with the front
doors open.
Whatever the flue collar size, a Defiant 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 flues relined for proper stove performance.
Accessories to help make the connection between
stainless steel chimney liners and your Defiant are
available through your local dealer.
Chimney Connector Guidelines
A chimney connector is the single-wall pipe that con-
nects the stove to the chimney. The chimney itself is the
masonry or prefabricated structure that encloses the
flue. Chimney connectors are used only to connect the
stove to the chimney.
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, 1.4432 or
1.4436 with flue wall thickness of at least 1 mm;
