2- Once the opening completed, you need to frame in the area to allow for the installation of a wall
thimble. A wall thimble is not required for installations through concrete walls.
3- You must first secure the wall thimble into the exterior wall surface. Then, do the same inside and
fasten the trim plate.
4- Then, from outside the building, slide a short chimney length (attached to the tee) through the wall
thimble. The chimney must extend at least 3 inches into the living space where it attaches to the
stove pipe.
5- You can now install the wall support. Simply slide the wall support up to the tee, ensuring that the
adapter on the support engages with the female coupler on the bottom of the tee. When the wall
support is level and properly positioned, you can use lag bolts to secure it into the wall studs. TO
complete the installation, install an insulated tee plug below the wall support.
