INSTALLATION NOTES 
Proper planning for your DuraTech Chimney 
installation will result in greater safety, 
efciency, 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 modied 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.
