INSTALLATION NOTES
Proper planning for your DuraTech Chimney
installation will result in greater safety,
efficiency, 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 modified parts. Each solid-fuel appliance
must be vented with its own chimney. 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.
