PRIMARY WEATHER SEAL
NOTE:
THE PRIMARY WEATHER SEAL MUST BE APP LIED ALONG THE HEAD, JAMB AND SILL MEMBERS AS SH OWN ABOVE.
THIS IS ESPECIALLY CRITICAL AT THE SILL SO THAT PROPER DRAINAGE OF WATER CAN TAKE PLACE. FOR EASE OF
INSTALLATION IT IS RECOMMENDED THAT THE PRIMARY SEAL BE APPLIED PRIOR TO INSTALLING GLASS AND FACE
CAPS.
THE SECONDARY WEATHER SEA L MUST BE APPLIED AT THE FACE OF THE COVER AT THE HEAD AND TOP 2" OF JAMB
ONLY. THIS PREVENTS WATER INFILTRATION DIRECTLY INTO THE SYSTEM FROM ABOVE.
FAILURE TO APPLY BOTH THE PRIMARY AND SECONDARY WEATHER SEA LS IN THE CORRECT LOCATIONS WILL
GREATLY AFFECT THE PERFORMANCE OF THE SYSTEM .
WHILE NOT REQUIRED FOR PROPER SYSTEM PERFORMANCE, THE COSMETIC SEAL MAY BE APPLIED ALONG THE
INTERIOR IF NEEDED.
KEEP AREA OPEN AT SILL
FOR SYSTEM WEEPAGE.
