Mendota DXV-35 DEEP TIMBER II Installation & Operating Instructions Manual page 29

WARNING: Only Horizontal Runs are allowed when using the Rear Vent Option.
When planning to install the DXV35 Fireplace with the rear vent option in an outside corner, it is recommended that
thorough calculations and measurements be made prior to any construction. The diagonal distance desired will de-
termine the exact location on the wall where the Horizontal Termination Cap will be placed relative to the inside cor-
ner.
8. 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.
9. Determine the desired floor level for the fireplace. Measure up 22-5/8" inches from this floor level and
mark a horizontal line on the wall that the vent pipe will penetrate.
10. Locate position where vent pipe will penetrate the outside wall. Since vent pipe sections "overlap" we sug-
gest 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
of all pipe sections manufactured by Simpson DuraVent.
11. Cut and frame a 12" wide x 12" high openings in the outside wall. 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 ob-
structed.
12. Connect vent pipe to the fireplace adapter on the rear of fireplace vent outlet.
13. The horizontal pipe must end flush with the exterior wall of the home. THERE MUST BE A MINIMUM
OF 1" CLEARANCE TO COMBUSTIBLES FROM ALL VENT PIECES (2" above horizontal runs).
14. A wall thimble must always be used when penetrating combustible wall materials.
NOTE: Combustible wall thickness must be 4" to 8" maximum.
15. 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.
sealant is used in the inner pipe joints
