Installation Guide

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 connector pipe until you have the
desired conguration (refer to the appliance
manufacturer’s installation instructions for
restrictions on connector 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 a
three piece unit which includes the cover plate,
sleeve extension, and the back portion with
shield. On the outside wall, install the back
portion of the Wall Thimble. Center the back
portion of the Wall Thimble (with shield inside
wall) in the framed opening of the outside wall.
Be sure to seal the ange 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) 1-1/2” wood
screws (Fig 20). Depending on the thickness
of your wall, you will need to adjust the shield
extension to insure that you have a continuous
shield throughout the wall penetration.
Adjustments can be made by sliding the
extension in or out of the back portion of the
shield. Verify that the shield extension reaches
the front cover plate when the cover plate is
in position. Do not install cover plate at this
time. When the shield extension is in position,
secure it to the back portion of the shield using
(4) sheet metal screws (Fig 20).
4. Install Tee Support: Install the Tee
Support on the outside wall. Position Tee
