IMPORTANT NOTES:
A flexible corrugated chimney
liner has much greater resis-
tance to the flow of flue gases
than does a rigid liner. For this
reason we recommend that a
larger, 4" liner be used on ver-
tical runs exceeding 15 feet or
that rigid venting be used as
illustrated on this page (see
Full Chimney Reline).
If a flexible corrugated chimney
liner is used, it must be fully
extended to eliminate any sag-
ging and to improve the ex-
haust flow.
