CONNECTING TO THE CHIMNEY:
Masonry Chimney Thimbles
When installing a Firelight CB into a masonry chimney
through a thimble(the opening through the chimney
wall to the flue), the thimble must be lined with ceramic
tile or metal and be securely cemented in place.
The chimney connector/stove pipe must slide
completely inside the thimble to the inner surface or
the flue liner. It may be necessary to make use of a
thimble sleeve (a pipe with a slightly smaller diameter
than standard stove pipe). This special pipe can be
easily installed into a thimble. See figure 4.
Make sure the connector pipe or thimble sleeve does
not protrude into the flue liner, thereby restricting the
area the smoke has to flow through. This bottle-neck
will have a negative affect on the chimney system.
The space that is cleared of combustible materials
must then remain empty. Sheet metal panels can then
be used to cover the area. However, when using a
panel on both sides of the wall each cover must be
installed on noncombustible spacers at least 1 from
the wall. If one panel of sheet metal is to be used it
may be installed flush to the wall.
SEE SECTION 5.3.1 and 5.3.2 of CAN/CSA -
B365-M91.
The chimney connector should be sealed at the thimble
with refractory cement and the stove pipe leading to
the stove should have a minimum of three screws.
DO NOT CONNECT THIS STOVE TO A
CHIMNEY FLUE SERVICING ANOTHER
APPLIANCE OF ANY KIND.
Connector pipe shall
be flush with the
inside of the flue tile
Hearthmount into a Masonry Fireplace
The Firelight CB may be installed into a masonry
fireplace provided the height of the opening is a
minimum of 31.
When installing the Firelight CB into a masonry
fireplace, code requires that the fireplace damper plate
be removed or securely fixed in the open position. A
connector pipe must then extend from the stoves flue
exit through the damper area of the fireplace and into
the chimney tile liner. See figure 5.
The inside area of the flue liner must not be less than
the area of the stoves flue exit, and cannot be more
than three times greater than the cross sectional area
of the stoves flue exit.
If the chimney liner is too large to accommodate the
stove, an approved relining system must be installed
to resize the flue.
A new sheet metal damper block-off plate must be
installed around the connector pipe at the damper
frame and sealed with the proper sealant (usually
High-Temp Silicone).
