Clearance Requirements
Clearances to Combustibles:
Refer to Section 3 for clearances to the appliance, man
-
tel, mantel legs and wall projection.
Refer to Section 5 for pipe clearances to combustibles.
Termination Cap
For installation of termination cap see minimum vent
heights for various pitched roofs. See Section 4.A.
Flue Damper
Fully lock the solid fuel fireplace’s flue damper in the open
position, OR completely remove it.
Venting Components
The LINK-DV30B is approved for use with the coaxial/co
-
linear venting application. The LINK-DV30B kit includes:
• Two 30 foot 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.
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.
Stainless Steel Flex Requirement - RAVE32-IFT-B
ONLY:
The RAVE32-IFT-B model requires the use of a 3 ft. stain
-
less steel flex liner (768-380A) to be installed directly to the
exhaust collar on the DV-46DVA-GCL connector.
Coaxial to Colinear Venting
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.
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 coaxial to colinear vent components are shown in
Section 12.A. The DV-46DVA-GCL must be recessed
into existing masonry fireplace. See Table 1 and Figure
4.21.
