Chimney Installation; Manufactured (Mobile) Home Installations - Lennox Hearth Products ST310 Installation And Operation Manual

CHIMNEY INSTALLATION

• Install chimney as per manufacturer's instructions. Some brands of
pipe may require removal of the spacer ring in the flue collar.
• All horizontal runs of pipe should be as short as possible and are
required by NFPA No. 211 to have an upward pitch or rise in the same
direction the smoke travels of no less than 1/4" to the linear foot. The
connector pipe must meet minimum clearances in any direction to
walls or other combustible materials. It must attach to a listed double
wall metal chimney at least 6" in diameter or to a masonry chimney
with a flue passage of at least 48 square inches.
• It is required that a chimney connector pipe not extend further than
the inner wall of the flue when it is connected to a masonry chimney
and that it either be cemented to the masonry or be installed without
cement in a thimble connected to the masonry wall. When the
connector is inserted into a thimble, the joint must be tight enough
so that it will not be dislodged in normal use. Install connector at
no less than the minimum clearances from the ceiling when using a
90-degree elbow to pass through combustible constructions.
• Chimney connector pipes should never pass through a floor, ceiling,
fire wall, partition, or combustible construction of any type unless
certain precautions are taken. The best method is to use a listed
thimble and a listed chimney in accordance with the manufacturer's
directions. NFPA No. 211 gives approved methods for passing a flue
pipe through combustible constructions (see Page 10).
