8.16 — Fan/Motor Cassette Installation
To close the fan/motor cassette:
1.
Check that all adjustment screws are tight, and check the linkage and IFGR damper for free movement before
closing the unit.
2.
Position the cassette into the front door.
3.
Slide the cassette into position until it begins to contact the inlet gasket, then measure the clearance between the
cassette flange and the front door mounting face. There must be clearance of at least 1/4” to provide adequate
gasket compression when the cassette is mounted tightly to the door.
4.
Secure the cassette with the fastening nuts.
5.
After the cassette has been secured to the front head, reconnect the davit to the front door by screwing in the
retaining bolt at the top centerline.
Do not remove the davit arm assembly from the motor/fan cassette without first verifying that the cassette is securely
bolted to the boiler. Failure to follow these instructions could result in serious injury or death.
