2) Locate and remove the four bolts that
hold the block-off plate on the back of 
the stove. Remove the plate. 
 
3) Place the flue collar on the back of the
stove over the rear flue exit with the 
gasket side towards the stove. Rotate the 
collar so the 3 chimney connector screws 
are easiest to access when necessary to 
install later. Replace the four bolts using 
the 10mm wrench. 
 
4) Place the cover plate over the flue exit
on the top of the stove, using the same 
four bolts that were removed.

HIMNEY
 
Consider two primary elements when 
connecting your stove to a masonry chimney: 
the chimney itself and the thimble where the 
stovepipe connects to the chimney. Use only 
Code approved masonry chimneys with a flue 
liner. 
 
Before connecting to a masonry chimney, hire a 
professional to examine the chimney for cracks, 
loose mortar, and other signs of deterioration 
and blockage. If the chimney needs repair, 
complete the project before installing and using 
your stove. Do not install your stove until the 
chimney is safe for use. 
 
Make sure the chimney’s cleanout is complete 
and working properly. To avoid a loss of draft, 
the cleanout must close off completely. If 
allowed to cool, your stove will perform poorly 
and creosote will build up in the chimney. 
 
Make sure the size of the chimney’s flue is 
appropriate for this stove and that it is not too 
large. Use a masonry chimney with an 8" x 8" 
(203 mm x 203 mm) tile size for best results. 
An oversized flue will contribute to the 
accumulation of creosote. 
Use the following checklist to ensure that your 
masonry chimney meets these minimum 
requirements: 
 
 
Chimney wall construction: 
Brick or modular block at least 4" (102 mm) 
thick. 
A rubble or stone wall at least 12" (305 mm) 
thick. 
 
 
Flue liner: 
Minimum thickness of 5/8" (16 mm).
Installed with refractory mortar.
At least 1" (25 mm) air space.
An equivalent flue liner must be a listed 
chimney liner system meeting type HT 
requirements or other approved material. 
 
 
Interior chimney requirements: 
At least 2" (51 mm) clearance to 
combustible
structure
Fire stops must be installed at the spaces 
where the chimney passes through floors 
and/or ceiling. 
Insulation must be 2" (51 mm) from the 
chimney. 
 
 
Exterior chimney requirements: 
At least 1" (25 mm) clearance to 
combustible structure.
