Typical Existing Masonry - Napoleon S Series Installation And Operation Manual

typical existing masonry

note:
Any opening between the masonry of the fireplace and the facing masonry MUST be sealed.
You can install your appliance using your existing masonry
chimney. To do so, use the following guidelines. If you are using a
masonry chimney, it is important that it be built in compliance with
the specifications of the Building Code in your region. It
must normally be lined with fire clay bricks, metal or clay
tiles sealed together with fire cement. (Round flues are
the most efficient).
A. Remove the fireplace damper or fasten it permanently open.
* We recommend the following method of sealing off the damper area around the liner.
B. * Measure the throat of the fireplace and mark this shape on a piece of 24 gauge sheet metal (flue cover);
cut a six-inch (6.75" / 171mm) hole to lie directly below the fireplace flue opening. Allow two inches of
material for a flange on all sides and cut to these measurements. Bend down the flanges. If you have never
done this before, it might be a good idea to make a cardboard pattern and test it first. Fasten this flue cover
in position as high as possible with two masonry screws per side through the flanges into the fireplace.
In Canada: Install a listed 6" (152mm) diameter flexible stainless steel liner from the top of the chimney to the insert
flue collar. Attach a stainless steel liner connector or elbow to the liner and insert onto the flue collar. Fasten with
three screws. Secure the top of the liner to the chimney cap using a liner support and chimney flashing. Cap the top
of the chimney liner assembly using an approved rain cap.
note:
This fireplace insert must be installed with a continuous chimney liner of 6" (152mm) diameter extending from
the fireplace insert to the top of the chimney. The chimney liner must conform to the Class 3 requirements of
CAN/ULC-S635, Standard for Lining Systems for Existing Masonry or Factory-Built Chimneys and Vents, or
CAN/ULC-S640, Standard for Lining Systems for New Masonry Chimneys.
In the United States: While it is not required, it is recommended that a chimney liner be installed that is continuous
from the insert to the top of the chimney, particularly when the insert is installed in a basement. For this type of
connection, use the "In Canada" installation instructions above.
If a continuous liner is not installed, a "direct flue connection" must be made. The direct flue connection requires a
non-combustible connector that extends from the insert into the chimney flue liner and also that the installed flue
cover be sealed below the entry point of the connector to prevent dilution of combustion products in the chimney
flue with air from inside the house. Cap the top of the chimney using an approved rain cap.
The following installation requirements must be observed when installing solid fuel burning inserts into factory built
fireplaces.
