Elevated Through The Wall Venting - Mendota DXV-35 DEEP TIMBER II Installation & Operating Instructions Manual

ELEVATED RISE THROUGH-THE-WALL VENTING
A-2.
The required vertical rise is 48 in. when used with a maximum horizontal run of 12 ft. For other venting confi-
gurations within these maximum limits, see Figure 6, PG. 14.
NOTE: The horizontal run of vent pipe must be level or have a ¼" rise for every 1' of run toward the termi-
nation. Never allow the vent to run downward. This will cause high temperatures and the possibility of a
fire.
USING OFFSETS AND RETURNS: A single 90
allowable maximum 12' horizontal run. Each additional 90
by 3'. Example: by using three total 90
1 = 2 elbows x 3' = 6'; 12' Max. - 6' of elbows = 6' of horizontal run). Note: 45º elbows reduce the maximum
horizontal distance by 1½ '.
SUPPORT: Horizontal runs of pipe will require one vent support for every 3 ft. of pipe.
CAUTION: If a vertical-to-horizontal elbow is enclosed within a wall, floor or ceiling, a top air space clear-
ance of 3" must be maintained. Be sure to maintain 1" air space to any combustibles (2" above ho-
rizontal runs).
IMPORTANT: REFER TO DRAWINGS ON PAGES 11 -15 WHILE FOLLOWING THESE INSTRUCTIONS.
The DXV-35 Fireplace must be installed by a qualified Mendota service person.
1. Position fireplace in desired location. See PG. 8 for guidelines on proper vent cap placement on exterior of
home. Check to determine if wall studs are in the way when vent system is attached. If this is the case you
may want to adjust the fireplace location.
2. Locate position where vent pipe will pass through any ceilings and will penetrate the outside wall. Since
vent pipe sections "overlap" we suggest pre-assembling and measuring the total vent pipe run so you can
more accurately locate the point where the vent pipe will penetrate the outside wall (See Figure 2: Exterior
Vent Locations, PG. 8). Be sure all vent components are properly twist locked and leak-proof. Be sure
1000 sealant is used in the inner pipe joints of all pipe sections manufactured by Simpson DuraVent.

3. Cut and frame a 9-1/2" wide x 10" high openings in the outside wall openings and 9" x 9" opening in ceiling
openings. The outside wall hole must be positioned so the vent system will run level or have a ¼" on rise
AND be perpendicular to the wall. The height of the opening must be located to meet all building codes
and not allow the termination to be easily blocked or obstructed. A ceiling fire stop spacer is required at
any floor (ceiling) opening.
4. Connect vent pipe to the fireplace adapter on top of fireplace vent outlet.
5. The horizontal pipe must end flush with the exterior wall of the home. Horizontal pipe will require a proper
support every 3 ft. of vent pipe. THERE MUST BE A MINIMUM OF 1" CLEAR-ANCE TO
COMBUSTIBLES FROM ALL VENT PIECES (2" above horizontal runs).
6. A wall thimble must always be used when penetrating combustible wall materials.
NOTE: Combustible wall thickness must be 4" to 8" maximum.
7. From the exterior of the home, slide the horizontal vent cap over the end of the horizontal pipe and tightly
secure the vent cap to the wall with screws. Seal with high quality caulking.
NOTE: Venting terminal should not be recessed into wall or siding.
