Note: Heat shields MUST overlap by a minimum of 1-1/2 in. (38 mm).
The heat shield is designed to be
used on a wall 4 in. to 7-1/4 in. (102 mm to 184 mm) thick.
If wall thickness is less than 4 in. (102 mm) the
existing heat shields must be field trimmed. If wall thickness is greater than 7-1/4 in. (184 mm) a DVP-HSM-B
