as needed to fit your installation. There are
two options when installing a Tee-Supported
installation: the Tee Support above the Tee, or

1. Place Appliance:
Position the appliance
according to the manufacturer’s instructions. It
is a good idea to try to position the appliance
so it will allow the chimney to line up centered
between studs.
2. Locate, Cut & Frame Opening:
Determine
the location where the chimney will pass through
the wall. The chimney should pass through
the wall, centered between two studs. The
height of the penetration can be determined
by positioning sections of stove pipe until you
have the desired configuration (refer to the
appliance manufacturer’s installation instructions
for restrictions on stove pipe). Cut and frame
an opening in the inner and outer walls at this
location. Refer to
Table 2
for the appropriate
framing dimensions.
3. Install Wall Thimble:
The Wall Thimble
is two-piece component which includes the
Interior half and the Exterior half. On the
outside wall, install the back portion of the Wall

Thimble (with shield inside wall) in the framed
opening of the outside wall. Be sure to seal
the flange of the Wall Thimble around the wall
by using a non-hardening waterproof sealant.
Attach the back portion of the Wall Thimble to
the outside wall using at least (4) 8-penny nails
or (4) #8, 1-1/2” wood screws. There must be
