4.1.1 CHIMNEY CONNECTION

Your chimney connector and chimney must have the same diameter as the appliance's exhaust fl ue outlet. The
appliance pipe must be made of aluminized or cold roll steel with a minimum 24 gauge thickness. It is strictly
forbidden to use galvanized steel.
A 6" diameter single wall chimney connector, used to connect the appliance to the chimney, must be installed with
the crimped end toward the appliance. This will ensure that the moisture which condenses from the burning wood
will fl ow back into the fi re chamber. Each joint in the chimney connector must be secured with at least three sheet
metal screws.
For installation of your chimney connector, the following recommendations may be useful.
• The chimney connector must be short and straight. For optimum performance it is recommended that
all horizontal runs have a minimum 1/4" rise per foot, with the upper end of the section toward the
chimney. For safe and proper operation of the appliance, see "INSTALLATION" instructions.
• To insure a good draft, the total horizontal length of the connector should never exceed 8' to 10'. In
the case of vertical installation, the total length of the connector can be longer and connected without
problem to the chimney at the ceiling level.
• There should never be more than two 90° elbows in the entire connector and chimney system. Never
start with a 90° elbow. Always go up vertically for at least 2 feet from the fl ue collar before using a 90°
elbow.
• The connector must not pass through any combustible material, nor may it pass through a concealed
space (such as an attic, roof space, or closet). If passing through a wall, ceiling, or into a masonry
chimney, use either chimney components listed for that specifi c use, or means acceptable to local
authorities having jurisdiction over the installation.
This appliance must be connected to:
A. A chimney complying with the requirements for Type
HT chimneys in the Standard for Chimneys, Factory-
Built, Residential Type and Building Heating Appli-
ance, or
B. A code-approved masonry chimney with a fl ue liner.
Vent the stove into a masonry chimney or an ap-
proved, insulated solid-fuel stainless-steel chimney
with as short and straight a length of 6" diameter
chimney connector as possible. Connection to a ma-
sonry chimney must be by a metal or masonry thimble
cemented in place.
