INSTALLATION NOTES
Proper planning for your DuraTech Chimney
installation will result in greater safety,
efciency, and convenience, as well as
saving time and money. You must use
only authorized DuraTech Chimney parts
to maintain a listed Chimney system (not
including the connector pipe). Do not mix
parts or try to match with other products,
or use improvised solutions. Do not install
damaged or modied parts. Table 1 lists the
authorized DuraTech Chimney components.
Practice good workmanship. Sloppy work
could jeopardize your chimney’s safety. Keep
electrical wiring and insulation away from all
chimneys and stovepipes. If you have any
questions, be sure to contact either your dealer
or DuraVent directly.
