1.
Determine where the chimney will pass through the wall.
For concrete walls cut a hole slightly larger than the chimney. If the
concrete wall has a wood wall inside it follow the instructions for a
combustible wall.
For combustible walls cut and frame a hole corresponding to the
rough opening required in the table on page 3.
2.
Combustible wall:
From outside, put the exterior portion (the galvanized part with the
square plate) of the wall radiation shield in the hole. Nail the shield in
place using 4 - 2" nails or # 8 x 1 1/2" wood screws. Seal the joint
between the shield and the wall with silicone caulking.
