BULLOCK 5650 Installation Instructions

INITIAL DAMPER TEST - Before installing Damper into wall, check damper's closing

operation. This can be achieved by removing UL33 rated fusible link. Hold the damper in

a stable upright position, then using the link strap or the "cricket bat", push the blade

vertically to the top. This will clear the blade over the two locking tabs. Pivot the blade

back against the stainless steel spring(s) to the fully open position, then let the blade

close and lock. Replace fusible link and close link strap.

Advise builder of damper location and direction of airflow.

Damper should be laid on a 3mm t0 4mm thick mortar bed to ensure airtight seal.

NOTE: Dampers are clearly labeled with "AIRFLOW" direction and "TOP" of unit.

Complete brickwork around and over damper, filling gap between brickwork and

damper with a thin layer of mortar.

Repeat INITIAL DAMPER TEST as outlined in point #1.

Connect ductwork to fire damper using fire rated mastic to fill recess if using raw edge

connection, or apply mastic to both surfaces of the TDF flange connections. (bolts must

be of a low melting point material.)
