WARNING!
Never install a single wall slip section or smoke-
pipe in a chase structure. The higher temperature of
this single wall pipe may radiate sufcient heat to
combustible chase materials to cause a re.
WARNING!
Detailed instructions for installation of the chase top, storm
collar and termination cap are packaged with these parts.
To avoid danger of re, all instructions must be strictly
followed, including the provision of air space clearance
between chimney system and enclosure. To protect against
the effects of corrosion on those parts exposed to the
weather, we recommend that the chase top be painted with
a rust-resistant paint.
