NOTE:
NFPA 80 DOES NOT APPROVE THE USE OF LEAD ANCHORS ON ROLLING FIRE SHUTTER INSTALLATIONS; DO NOT USE LEAD ANCHORS.
Temporarily prop the flame baffle in its upper-most position before attaching the front hood. This will insure it is guided into this position. Remember to remove the props
later. Position the front hood on the hood straps. Align and punch all holes in the hood at the hole locations in the hood straps. Attach the front hood with the self-tapping
screws provided, but do not tighten the screws at this time, since the housings must slide under the front hood.
HINT: IF THE SHUTTER IS MOUNTED TOTALLY UNDER THE LINTEL AND THE FASCIA SIDE IS ACCESSIBLE, IT MAY BE EASIER TO INSTALL THE FRONT HOOD FIRST,
THEN SLIDE IN THE FLAME BAFFLE (IF REQ’D) FROM THE FASCIA SIDE.
Attach the A.W. bracket housing and sandwich the flanges between the hood straps and the front hood (see Figure #23). Check to insure the cutouts, as provided, are large
enough so as not to interfere with the drop arm throughout its travel. Trim if necessary. Now tighten all screws in the vicinity of AW bracket locking hood/housings in place.
Attach the governor bracket housing in similar manner, and proceed to tighten all remaining hood screws. Remove the temporary flame baffle props, making sure only the
fusible tab holds the baffle in its upper position.
Proceed to attach the back hood to the hood straps. Align and punch all holes in the back hood at the points where holes are provided in the hood straps.
Hoods, Supports & Housings (above lintel)
HINT: LOWER THE SHUTTER TO OFFER THE MAXIMUM CLEARANCE BETWEEN THE COIL AND THE LINTEL.
THE FRONT HOOD MAY CONTAIN A FLAME BAFFLE FUSIBLE TAB LOCATED INSIDE. THE FLAME BAFFLE (IF PROVIDED) MUST RESET ABOVE THIS TAB AND BE CONTAINED
BY IT (SEE FIGURE #23 INSET)
Fasten the hood to the existing holes in the bracket flanges using the self-tapping screws provided. Do
not tighten screws at this time, since the housings must slide under the front hood.
