Color Note: The black painted finish of the BRV34 can be used
as-is or as a primer coat for a color finish of your choice. Clean the
surface of all dirt, grease and oil before applying a color finish.
Use a high quality finish to best serve the conditions of your
application.
5. Cut shingles as shown allowing the shingles to fit around the
housing of the roof jack when installed. Apply roofing cement to
seal around the ductwork as shown below. (Figure 4)
