Draft Requirements; Chimney Installation; Factory Built Chimney; Masonry Chimney - SCAN 5-2 Instructions For Installation And Use Manual

Draft Requirements:

Scan 5.2 is only one component of the total system. The venting system is equally important for
achieving the required flow of combustion air to the firebox and for safely removing unwanted
combustion byproducts from the appliance. If the venting system's design does not promote these
ends, the system may not function properly. Poorly functioning venting systems may create
performance problems as well as be a safety hazard (i.e. an oversized chimney may result in less than
optimum performance. Installations into a large, masonry chimney may require a liner to improve
performance). A draft test should read greater than .04" W.C. (Inches Water Column) and less than
.08" W.C. The table below shows dimension of connection piece and data for draft requirements for
the stove:

All models
The chimney draught depends on the weather conditions. In stormy weather, you may reduce the
chimney draught by closing the damper in the smoke pipe (if a damper has been installed). If the
chimney draught is strong, the combustion air supply must be reduced additionally.

Chimney Installation:

DO NOT CONNECT THIS UNIT TO A CHIMNEY FLUE SERVING ANOTHER APPLIANCE. DO
NOT CONNECT TO ANY AIR DISTRIBUTION DUCT OR SYSTEM.
SCAN 5.2 is listed for installation as a vertically top or rear vented stove using a listed class A
(UL103HT) for Canada (CAN/ULC-S629) factory built chimney exiting through the ceiling/attic/roof.
The inside diameter of the chimney, connector pipe must not be smaller than 6" (152 cm) diameter.
Single wall 24 gauge MSG (0.58 – 0.71 mm) and adapter must not be smaller than 6" (152 mm), may
be used in the room where the stove is installed, follow the chimney manufacturer's instruction for
installation of chimney and chimney adapter. In Canada, where passage through wall, or partition of
combustible construction is desired, the installation shall conform to CAN/CSA B365.

Factory Built Chimney

When a metal prefabricated chimney is used, the manufacturer's installation instructions must be
followed. You must also purchase (from the same manufacturer) and install the ceiling support
package or wall pass-through and "T" section package, fire stops (where needed), insulation shield,
roof flashing, chimney cap, etc. Maintain proper clearance to the structure as recommended by the
manufacturer. The chimney must be the required height above the roof or other obstructions for
safety and proper draft operation. See page 11 for chimney termination

Masonry Chimney

Ensure that a masonry chimney meets the minimum standards of the National Fire Protection
Association (NFPA) by having it inspected by a professional. Make sure there are no cracks, loose
mortar or other signs of deterioration and blockage. Have the chimney cleaned before the stove is
installed and operated. When connecting the stove through a combustible wall to a masonry chimney,
special methods are needed. Refer to Combustible Wall Chimney Connector Pass-Throughs on page
10 and 11.
