7.9.1 Installation instructions
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.
7.10 Supply of combustion air
Legally, it is not mandatory to connect your fireplace to a fresh air intake unless it is required by the local
code or the manufacturer. However, if you want to meet the Novo Climate or R2000 requirements, an
external air intake will be required. The fresh air intake promotes proper combustion and prevents the risk
of house depressurization. Although the external air supply is not a guarantee against the risk of smoke
return caused by house depressurization, it will certainly minimize the risk.
•
IT IS STRONGLY RECOMMENDED TO INSTALL A MECHANICAL DAMPER TO CLOSE THE FRESH AIR
INTAKE WHEN THE FIREPLACE IS NOT IN USE.
•
IT IS STRONGLY RECOMMENDED TO INSTALL A CARBON MONOXIDE (CO) DETECTOR/ALARM IN
THE ROOM WHERE THE FIREPLACE IS INSTALLED. THE CO DETECTOR WILL WARN YOU IF, FOR ANY
REASON, THE WOOD FIREPLACE FAILS TO FUNCTION CORRECTLY.
7.10.1 AIR INTAKE IN CONVENTIONAL HOUSES
The easiest and most reliable supply of combustion air for your wood fireplace is from the room in which it
is installed. The room air is already preheated so it will not cool the fire and its availability is not affected by
the pressure of the wind on the house. However, the combustion of wood requires a large volume of air. It
will take only a few hours to consume the equivalent of the entire volume of air contained inside your
home. This air will be replaced by new cold air from outside either through tiny cracks in your home or via
your air exchanger. It is strongly recommended to install an external air intake to increase your heating
efficiency and to avoid consuming the preheated air you already paid for.
