Venting Components
The LINK-DV30B is approved for use with the coaxial/co-
linear venting application. The LINK-DV30B kit includes:
• Two 30 feet sections of flexible vent pipe (3 inches Ø).
One section is used to draw combustion air and the other
section is used to expel exhaust gases.
• One
vertical termination cap.
WARNING! Risk of Fire!
Coaxial to colinear venting con-
figuration may only be used in existing non-combustible
chimney. Installation in any other venting application
could cause fire.
Prior to installing the gas appliance:
• Have the chimney and adjacent structure inspected
and cleaned by qualified professionals. Hearth & Home
Technologies recommends that NFI or CSIA certified
professionals, or technicians under the direction of certi-
fied professionals, conduct a minimum of a NFPA 211
Level 2 inspection of the chimney.
• Replace component parts of the chimney and fireplace
as specified by the professionals.
• Ensure all joints are properly engaged and the chimney
is properly secured.

The coaxial to colinear adapter (DV-46DVA-GCL) is ap-
proved for installations into solid fuel masonry or factory
built fireplaces that have been installed in accordance
with the National, Provincial, State and local building
codes. The DV-46DVA-GCL must be recessed into exist-
