Chimney Conversion
Before conversion, have the existing installation inspected by a
qualified chimney sweep or professional installer. The existing
chimney system must be in serviceable condition, and functionally
sound. Before proceeding with following installations, check with
local building jurisdiction to verify this type of installation is allowed
in your area.
Follow DIAG.7 for allowable venting configurations for installation
in existing through masonry chimney. Route the exhaust gases and
intake air through the existing masonry chimney.
7.8.1 Coaxial to Co-Linear Venting Configurations
IMPORTANT: Horizontal vent sections require at least 1/4” (6mm) rise
for every 12” (305mm) of travel.
IMPORTANT: The horizontal heat shield included with this fireplace
must be installed when using a 90° elbow off the top of the appliance.
IMPORTANT: Care should be taken when installing flexible pipe to avoid
a tight bend that may cause abrasion or damage to the flexible pipe.
