ASSEMBLY & INSTALLATION
Vent Pass-Through (Parallel Wall Installation on an Interior Partition Wall)
1. An unobstructed wall pass-through is required to allow for a safe installation of the fireplace vent com-
ponents. This will necessitate removal of a portion of the interior wall covering (e.g., sheetrock or
plaster and lath), on both sides of the partition wall and any adjacent internal wall materials (like insu-
lation).
2. Scribe a 9 5/8” diameter hole around the vent pass-through center mark using a compass.
3. Use a long drill (1/8” diameter) that is held square and level to the inside wall to transfer the vent pass-
through center location from the inner wall covering through to the wall covering on the back side of
the partition wall.
4. Carefully cut the inner wall covering along the scribed line and remove the circular wall piece. Note:
It is important to locate electrical wiring in the wall before beginning the installation process. An elec-
trician should be consulted if there is any question about wiring locations. Failure to locate and protect
wiring during the installation process my result in electrical shock or fire.
5. Remove any insulation materials from wall in the area defined by the pass-through hole.
6. Building codes in your area may require that you add blocking above and below the vent opening. The
blocking should be above and below the 9 5/8” vent opening you made in the wall and should not ob-
struct that opening. The blocking should extend to adjacent wall studs.
7. Next, mark and cut a 9 5/8” diameter hole through the wall covering on the back side of the partition
wall using the locating hole you drilled in Step 2.
8. When installing the fireplace on a partition wall, the venting may be penetrating one or more interior
walls, an exterior wall, the ceiling or the roof.
9. It is important to lay out the locations of all vent pass-through’s before you begin the installation to in-
sure that the venting will line-up correctly and that the walls and ceiling meet the needed clearances to
the vent pipe.
10. The vent pass-through in the partition wall where the fireplace is mounted must be done in accordance
with the instructions for a parallel wall installation on an outside wall, following steps 1 through 6.
Vent Pipe Heat Shields
Special telescoping double heat shields for the vent pipe are provided with the West End
fireplace. These heat shields are a critical part of a safe installation. They are designed to
protect combustible materials in the wall immediately behind the fireplace. The only ex-
ception to this is if the corner installation kit (Part Number CK-26-1) is used. With the
corner kit, the heat shields are installed where the venting passes through the first adjacent
side wall. See the instructions included with the corner kit for specific details.
