outline of the hole and drill a pilot hole in its center.
- Break out part of the wall covering within the outline to confirm that
the hole will be centered between studs and that no electrical wires
could be cut by the saw.
2. For a non-combustible wall (concrete block or poured
foundation), cut a hole (3/16") greater in diameter than the outside
diameter of the chimney as per Table 3.
3. After framing in your opening to the dimensions specified to the
Framing Tables 1 or 3, install the outer half (with the unfinished square
plate) of the Wall Thimble into the outside wall opening. Secure in
place with appropriate fasteners through the pre-punched holes.

4. Install the inner half (with round plate) of the Wall Thimble into the
inside wall opening, ensuring that the shield slides over the shield of
the outer half. Once in place and flush against the wall, install the black
finishing trim plate onto the wall surface and fasten in place with ap-
propriate fasteners through the 4 pre-punched holes.
NOTE: To reduce cold air infiltration into the dwelling you
can install the optional Universal Shielding Insulation (JUSI)
into the Wall Thimble. See separate installation instructions
