Chimney required for the PB150 is 4" Class "L" (also known as PL
vent). A starting collar must be used to attach the venting system to
the furnace. When connecting into a Class "A" or masonry chimney a
listed 4" liner MUST be used to prevent back drafting of the chimney.
EXISTING CLASS "A" CHIMNEY:
Run 4" Class "PL" connector from the furnace connection to a positive
connection with the class "A" chimney. A LISTED 4" STAINLESS STEEL
LINER MUST BE USED IN CLASS "A" CHIMNEYS. Make sure each
joint is firmly locked into place. Make sure the attachment of Class "PL"
to the Class "A" chimney is secure with sheet metal screws. Seal all joints
with high temperature silicone. Class "PL" connector should maintain a
pitch on rise from the furnace to the chimney of at least ¼" per foot.

EXISTING MASONRY CHIMNEY: Run 4" Class "PL" connector from
the furnace connection to a positive connection with the masonry
chimney. Make sure each joint is firmly locked in place. Make sure
the penetration of the Class "PL" connector into the masonry chimney
is sound and secured with high temperature cement. Seal all joints with
high temperature silicone. Class "PL" connector should maintain a pitch
on rise from the furnace to the chimney of at least ¼" per foot.
A LISTED 4" STAINLESS STEEL LINER MUST BE USED IN MASONRY
CHIMNEYS. Your new furnace is so efficient; an unlined chimney could
remain cold and cause a downward pressure creating poor burning,
incomplete combustion or back draft.
