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.
