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

3. Install Wall Thimble:
The Wall Thimble is a
three piece unit which includes the cover plate,

around the wall by using a non-hardening
waterproof sealant. Attach the back portion
of the Wall Thimble to the outside wall using
