INSTRUCTIONS:
2A. BECAUSE OF THE GREAT VARIETY OF RAILS
THAT POLY-VENT CAN BE MOUNTED TO,
MOUNTING HARDWARE IS NOT PROVIDED. IT
IS NECESSARY FOR THE INSTALLER TO OBTAIN
APPROPRIATE FASTENERS.
2B. MOUNT TOP GUTTER AND BACKER PLATE TO
RAILS. HEM OF BACKER PLATE SHOULD FACE
MOUNTING RAILS. THE TOP EDGE OF BOTH THE
BACKER PLATE AND TOP GUTTER SHOULD BE

2C. MOUNT BOTTOM GUTTER TO LOWER RAIL. DO
NOT USE THE FIRST THREE MOUNTING HOLES.
THESE WILL BE USED IN STEP 3 TO MOUNT THE
