Bend the sheet metal as indicated on the template at a 45 degree angle on each side after cutting the
sheet metal (This 2" lip will allow you to screw this plate into the smoke chamber inside your

Determine the position of where to cut the 6-1/4" hole in the sheet metal plate so that it lines up with
the chimney flue opening and the final position of the wood burning appliance, then cut the hole. If
you are installing surround panels with your insert, refer to the section "SURROUND PANEL
INSTALLATION" for how to position your insert correctly.

Put the plate in position and drill the mounting holes. Then bolt into position using the mounting bolts.
The seal can be completed by using fiberglass insulation and/or furnace cement between the
masonry and the block-off plate.
NOTE:
Allow the furnace cement to cure for 12 to 24 hours before starting a fire.
