The DuraVent Direct Vent Chimney Liner
System is an engineered product that has
been designed and tested for use with an
approved list of direct vent gas appliances. The

Liner System.

manufactured or approved by DuraVent.
• Installation other than as instructed by
DuraVent and the appliance manufacturer.
Consult your local building codes before
beginning the installation.
WARNING
•Always maintain required clearances (air
spaces) to nearby combustibles to prevent a
fire hazard. Be sure to check the appliance
manufacturer's installation instructions for
minimum clearance requirements between the
outer walls of the vent pipe/liner system and
nearby combustible surfaces. Be sure to check
the vent termination clearance requirements
from decks, windows, soffits, gas regulators,
and air supply inlets, as specified in local
building codes.
• The gas appliance and vent system must be
vented directly to the outside of the building,
and never be attached to a chimney serving a
separate solid fuel or gas-burning appliance.
Each direct vent gas appliance must use it's
own separate vent system. Common vent
systems are prohibited.
SAFETY PRECAUTIONS FOR THE
INSTALLER
• Wear gloves and safety glasses for

protection.
• Exercise extreme caution when using
ladders or on roof tops.
• Be aware of electrical wiring locations in
