Flue Connection; Connection To Existing Chimney - Morso 2B Standard Installation And Operating Instructions Manual

1.4 Flue Connection

A flue collar ise placed in the firebox area.
Use a 24 MSG black or blue chimney connector or listed double wall chimney connector. Refer
to local codes and the chimney manufacturer's instructions for precautions required for passing
a chimney through a combustible wall or ceiling. Remember to secure the chimney connector
with a minimum of three screws to the product and to each adjoining section.
Position the stove and connect to the flue system.
Wear gloves and protective eyewear when drilling, cutting or joining sections of
chimney connector
1.5 Connection to the existing chimney
A chimney connector is the double-wall or single-wall pipe that connects the stove to the chimney.
The chimney itself is the masonry or prefabricated structure that encloses the flue. Chim-
ney connectors are used only to connect the stove to the chimney.
Double-wall connectors must be tested and listed for use with solid-fuel burning appliances.
Single-wall connectors should be made of 24 gauge or heavier gauge steel. Do not use galva-
nized connector; it cannot withstand the high-temperatures that smoke and exhaust gases can
reach, and may release toxic furnes under high heat. The connector must be 6 inches (150mm)
in diameter.
If possible, do not pass the chimney connector through a combustible wall or ceiling.
If passage through a combustible wall is unavoidable, refer to the sections on Wall
Pass- Throughs. Do not pass the connector through an attic, a closet or similar
concealed space when installing the chimney connectors.
It is important to keep the flue gases moving smoothly in the right direction. Do not vent into a
large void at this location; rather form one continuous section all the way up. Use mild bends
(e.g. 45º vs. 90º) rather than sharp angles where a change of direction is required. All parts of
the venting must be accessible for cleaning purposes.
In horizontal runs of chimney, maintain a distance of 18 inches from the ceiling. Keep it as short
and direct as possible, with no more than two 90 degree turns. Slope horizontal runs of con-
nector upward 1/4 inch per foot (20 mm per metre) going from the stove toward the chimney.
The recommended maximum length of a horizontal run is 3 feet (1 metre), and the total length
should be no longer than 8 feet (2.5 metres).
Information on assembling and installing connectors is provided by the manufacturer's instruc-
tions exactly as you assemble the connector and attach it to the stove and chimney.
Be sure the installed stove and chimney connector are correct distances from near by
combustible materials. See the clearance paragraph page 8.
Where passage through a wall or partition of combustible construction is desired, the installation
shall conform to CAN/CSA-B365.
