Chimney - Hi-Flame HF-737U Installation And Operation Instructions Manual

This prevents any amount of condensed or liquid creosote from running down the outside of the
pipe or the stovetop. All joints, including the flue collar connection, must be secured with three
sheet metal screws to ensure that the sections do not separate.
For the best performance, the chimney connector should be as short and direct as possible,
with no more than two 90° elbows. The maximum horizontal run is 36" (91.44 cm) and a
recommended total length of stovepipe should not exceed 10 feet (3m). Always slope horizontal
runs upward ¼" (6.35mm) per foot toward the chimney.
No part of the chimney connector may pass through an attic or roof space, closet or other
concealed space, or through a floor or ceiling. All sections of the chimney connectors must be
accessible for cleaning. Where passage through a wall or partition of combustible construction
is desired, the installation must conform to National Fire Protection Association (NFPA) 211,
and is also addressed in this manual.
