SUPPORT METHODS AND HEIGHT LIMITS
1.
Several support and guiding methods are used to
anchor a chimney against upward, downward and
angular displacement
2.
These supports and guides used with thermal
expansion devices, prevent bending stresses on the
chimney elbows and joints
NOTE:
All the weight of the section must be supported by the
inner flue. Never support any chimney duct from the
outer wall.
