sheet steel supports that is a minimum of 24-gauge thickness and is securely fastened to the wall
surfaces. Any fasteners used to secure the chimney section shall not penetrate any portion of the
chimney flue liner. A minimum of three screws per chimney connector must be used.
A chimney connector shall not pass through an attic, roof space, closet, floor, ceiling, or similar
concealed space. Where passage through a wall or partition of combustible construction is desired or
necessary, the installation shall conform to CAN/CSA-B365.
Whatever brand of chimney system is purchased for your Ovation installation, you must ensure that all
chimney manufacturer’s installation instructions are followed and that all national and local codes have
been met.
OUTSIDE AIR COMBUSTION
It is imperative that the installer or homeowner ensures that a minimum of at least eight square inches
(fifty square centimeters) of outside air be admitted to the hearth room or directly to the stove. If
installation allows, a four-inch diameter pipe can be brought in through an exterior wall and connected
to the freestanding Ovation stove using the optional fresh air adapter.
Provision for outside combustion air may be necessary to ensure that fuel-burning appliances do not
discharge byproducts of combustion into the house. Guidelines to determine the need for additional
combustion air may not be adequate for every situation. If in doubt, it is advisable to provide outside
air.
Outside combustion air may be required if:
1. The Ovation stove does not draw steadily, smoke rollout occurs, fuel burns poorly, or back-
drafts occur whether or not combustion is present.
2. Existing fuel-fired equipment in the house, such as fireplaces or other heating appliances smell,
do not operate properly, suffer smoke rollout when opened, or back-draft occurs whether or not
combustion is present.
3. The home is equipped with a well-sealed vapor barrier and tight fitting windows or has any
powered devices that exhaust house air.
4. There is excessive condensation on home windows in the winter.
5. A ventilation system is installed in the house.
If any of these or other indicators suggests that infiltration air is inadequate, additional combustion air
should be provided from the outdoors to the Ovation appliance. Outside combustion air can be
provided to the appliance by the following means:
1. Direct connection: appliances can only use direct connection of outside combustion air if they
are certified for this type installation. Follow the Ovation instructions for direct connection of
outside combustion air.
2. Indirect connection: for appliances not certified for direct connection of outside combustion
air, outside air can be ducted to within twelve inches of the appliance.
3. Mechanical ventilation: if the house has a ventilation system (air change or heat recovery):
a. The ventilation system may be able to provide sufficient combustion make-up air for
the Ovation appliance.
b. The homeowner should be informed that the ventilation system might need to be re-
balanced by a ventilation technician after installation of the Ovation stove.
