and bolt assemblies of type designed to give holding power beyond tensile
and shearing strength of bolt. Minimum fastener penetration shall be not
less than that recommended by manufacturer for type fastener and wall
material involved.
3.3
OPERATORS
Install operators before glazing. Plumb and level shaft risers and runs.
Adjust ventilators for free opening and tight closing. Secure housings and
adjustable supports to wall. Anchor operator parts to steel window
mullions with 13 mm 1/2 inch bolts. Couple individual lengths of shafting
with steel rivets or bolts. Leave mechanical equipment and ventilators in
proper operating condition.
3.4
WEATHERSTRIPPING
Use bronze, spring-brass, or stainless steel and secure with non-ferrous
screws. Secure weatherstripping or rubbing-blocks to parting-strip and
each end of meeting-rails. For solid bar stock windows, use manufacturer's
standard weatherstripping inserted into groove.
3.5
ADJUSTMENTS AFTER INSTALLATION
After installation of windows and completion of glazing and field painting,
adjust all ventilators and hardware to operate smoothly and to provide
weathertight sealing when ventilators are closed and locked. Lubricate
hardware and operating parts. Adjust weatherstripping to assure
weathertight contact with frames when ventilators are closed and locked.
Weatherstripping shall not cause binding of sash, or prevent closing and
locking of ventilator.
3.6
CLEANING
Clean interior and exterior surfaces of window units of mortar, plaster,
paint spattering spots, and other foreign matter to present a neat
appearance and to prevent fouling of weathering surfaces and
weatherstripping, or interference with operation of hardware. Clean and
touch up abraded surfaces. Replace with new windows any stained,
discolored, or abraded windows that cannot be restored to original
condition.
