66 _____________________________________________________________________
Follow these steps:
1. Position the fireplace in its location.
Temporarily install the elbow or
chimney section (A) on the top of the
fireplace and, using a level, mark with
an oval the location where the flue
liner will enter the masonry chimney.
2. In the middle of the oval, drill a hole in
the masonry chimney at 45
°
or 30
°
.
3. Increase the size of the hole until a
45
°
or 30
°
insulated liner adapter (B)
can be easily slipped through.
4. Slide the liner (C) down from the top
of the masonry chimney until you
reach the hole level.
5. Slip through the hole a 45
°
or 30
°
insulated liner adapter and connect it
to the liner.
6. Seal the opening around the liner with
high temperature refractory cement.
7. Then, follow the chimney
manufacturer’s instructions to
connect the extended liner section to
the special chimney connector.
Note: Make sure the liner exceeds at least
12” (30 cm) the top of masonry chimney.
8.10 SUPPLY OF COMBUSTION AIR
In Canada, wood fireplaces are not required to have a supply of combustion air from outdoors
because research has shown that these supplies do not give protection against house
depressurization and may fail to supply combustion air during windy weather. However, to protect
against the risk of smoke spillage due to house depressurization, a carbon monoxide (CO)
detector/alarm is required in the room where the fireplace is installed. The CO detector will
provide warning if for any reason the wood fireplace fails to function correctly.
