A. Design and Installation Considerations
1. Appliance Location
NOTICE:
Check building codes prior to installation.
• Installation MUST comply with local, regional, state and
national codes and regulations.
• Consult insurance carrier, local building inspector, fire
officials or authorities having jurisdiction over restrictions,
installation inspection and permits.
It is a good idea to plan your installation on paper, using exact
measurements for clearances and floor protection, before
actually beginning the installation
Consideration must be given to:
• Safety, convenience, traffic flow
• Placement of the chimney and chimney connector.
• If you are not using an existing chimney, place the
appliance where there will be a clear passage for a
factory-built listed chimney through the ceiling and roof.
• Installing an optional outside air kit would affect the
location of the vent termination.
CAUTION!
If burning shelled field corn, you must use
approved venting specifically designed for corn to prevent
corrosion or degradation. Follow the instructions from the
venting manufacturer.
