IMPORTANT NOTES:
A fl exible corrugated chimney liner has much greater resistance to
the fl ow of fl ue gases than does a rigid liner. For this reason we
recommend that a larger, 4” liner be used on vertical runs exceeding
15 feet or that rigid venting be used as illustrated on this page (see
Full Chimney Reline).
If a fl exible corrugated chimney liner is used, it must be fully extended
to eliminate any sagging and to improve the exhaust fl ow.
Do not block opening at front of insert (below door).
