feet of DuraTech Chimney. The required parts
and general conguration are as shown in

is a good idea to try to position the appliance
so it will allow the chimney to line up centered

3. Install Wall Thimble: The Wall Thimble is a
three piece unit which includes the cover plate,
sleeve extension, and the back portion with

portion of the Wall Thimble. Center the back
portion of the Wall Thimble (with shield inside

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
