INSTALLATION GUIDELINES
These basic installation guidelines are for use with typical or standard applications. It is always recommended to seek advice from a licensed
professional, and to check with your local building inspector or building permit office for approvals and possible variations that may apply.
CAUTION!
Working above grade is inherently dangerous, be sure that proper fall protection measures are in place.
When working with power tools and sheet metal, gloves and eye protection are absolutely required.
