Mendota DXV-60 Installation & Operating Instructions Manual page 16

MINIMUM RISE THROUGH-THE-WALL VENTING
A-1
The minimum vertical rise for vent installation through the wall is 21-3/4"(32-1/4" LPG)from the top of the
fireplace to the centerline of the 90º elbow. NOTE: We recommend always using the most vertical rise the
installation will allow, especially for LP gas installations and for installations at higher altitudes.
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, 2000
Do not fill air spaces with insulation or other material.
IMPORTANT: REFER TO DRAWINGS ON PAGE 11 WHILE FOLLOWING THESE INSTRUCTIONS.
The DXV-60 Fireplace must be installed by a qualified Mendota approved service person.
1. Position fireplace in desired location. See PAGE 8 for guidelines on proper vent cap placement on the ex-
terior 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 21-3/4"(32-1/4" LPG) from top of fireplace to centerline
of 90 elbow (See
º FIGURE 1
netrate the wall.
3. Cut and frame an opening in the outside wall properly sized for the wall thimble you will be using (See
Wall Thimble manufacturer's instructions). The hole must be positioned so the vent system will run level
or have a ¼ " rise per foot of run AND be perpendicular to the wall. The height of the opening must be lo-
cated to meet all local and national building codes and not allow the termination to be easily blocked or ob-
structed. The wall thimble opening in the wall must be framed to provide a minimum of either two
horizontal or two vertical framed supports. If wall being penetrated is non-combustible material, i.e. maso-
nry block, brick, etc., a 8 ½" diameter hole is acceptable.
4. Be sure all component connections are in their fully twist-locked position and are leak-proof. Be sure
2000 sealant is used on the inner pipe joints of all adjustable (telescoping) pipe sections (Dura Vent only).

*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.
7. If the Horizontal Vent Cap is installed on a wall covered with Vinyl, Wood or a Combustible siding
material, always install the Mendota Heat Shield #AA-11-00458.
NOTE: Venting terminal should not be recessed into the wall or siding. Always use the Mendota Heat
Shield #AA-11-00458 when installing a horizontal vent cap over Vinyl, Wood or a Combustible materials.
sealant must be used on the inner pipe joints (Dura Vent only).
