2. Locate, Cut & Frame Opening: Determine

height of the penetration can be determined
by positioning sections of stove pipe until you
have the desired configuration (refer to the

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

Interior half and the Exterior half. On the
outside wall, install the back portion of the Wall
