A-1 MINIMUM RISE THROUGH-THE-WALL VENTING FOR NG AND LPG
WARNING: ALWAYS USE HEAT SHIELD (#AA-11-00458) WHEN EXTERIOR WALL COVERING IS MADE OF VINYL, WOOD OR
OTHER COMBUSTIBLE MATERIALS. HEAT SHIELD (#AA-11-00458) IS INCLUDED WITH THE DXV45 FIREPLACE.
The horizontal distance from flue outlet center to outside wall must not exceed 24" if a 90
o
elbow is connected
directly to flue outlet. ALWAYS MAINTAIN 1" CLEARANCES FROM VENT PIPE TO COMBUSTIBLES,
2" ABOVE PIPE ON HORIZONTAL RUNS. Use "fixed" pipe sections in place of adjustable pipe sections
wherever possible. If adjustable pipe sections must be used, 1000
º Millpak sealant (#65-06-00909) must be
used on the inner pipe joints (Duravent Only). Do not fill air spaces within the required clearance distances (1”
around vertical pipe sections and 2” above horizontal pipes and fittings) with insulation or other material.
1. Position fireplace in desired location. See pg. 8 for guidelines on proper vent cap placement on the exterior
of home. Check to determine if wall studs are in the way when venting system is attached. If this is the
case, you may want to adjust the fireplace location.
2. Measure from the top of the fireplace up minimum 7 1/2" from top of fireplace to centerline of 90
º elbow
(See
FIGURE 1. pg. 4) and mark wall directly at the center of where the vent pipe will penetrate the wall.
3. Cut and frame a 10-3/4" x 10-3/4" opening in the outside wall. The hole must be positioned so the vent sys-
tem will run level or have a ¼ " rise AND be perpendicular to the wall. The height of the opening must be
located to meet all local and national building codes and not allow the termination to be easily blocked or
obstructed. If wall being penetrated is non-combustible material, i.e. masonry block, brick, etc., an 8 ½" di-
ameter hole is acceptable. A Wall Thimble (#45-01-00229) must be used when penetrating a combustible
wall.
4. Make sure that all component connections are in their fully twist-locked position and are leak-proof. Make
sure that 1000
º Millpak sealant (#65-06-00909) is used on the inner pipe joints of all pipe sections (Dura
Vent only).
IMPORTANT: REFER TO DRAWINGS ON PAGE 10 & 11 WHILE FOLLOWING THESE
INSTRUCTIONS.

*NOTE: DO NOT SEPARATE TELESCOPING SECTIONS. USE AS COMPLETE ASSEMBLIES.
5. The length of the horizontal piece that fits through the wall will be determined by the thickness of the wall.
When installed, the end of the horizontal piece must be flush with the exterior wall of the home. There
MUST be a minimum of 1" air space clearance to combustibles from all vent pieces (2" above horizontal
runs).
6. From the exterior of the home, slide the horizontal vent cap over the end of the horizontal pipe and tightly
secure the cap to the wall with screws. Seal with a high quality caulking.
NOTE: The Horizontal Vent Cap should not be recessed into the wall or siding.
