UNPACKING AND ASSEMBLY : INDUCED DRAFT FACE MOUNTED BLOWER ASSEMBLY
5. Apply high temperature anti-seize lubricant to the motor shaft, place the key in the keyway, and slide the blower wheel onto the shaft, making sure that the keyway notch in the blower wheel hub aligns w ith the key on the motor shaft. If the blower wheel will not slide over the shaft, use a ½” outside wire brush (such as those used for cleaning the outside surface of copper tubes) and remove any minor burrs from the shaft of the motor. 6. Slide the blower wheel down on the shaft until the back surface of the hub is approximately 1/16” clear of the motor mount gasket. The blower wheel should turn freely without touching the gasket. The motor shaft will not protrude past the hub of the blower wheel.
7. Tighten the two set screws in the hub of the blower wheel with the supplied allen wrench to secure the wheel to the shaft. BOTH SET SCREWS MUST BE TIGHTENED.
8. Install the isolation bushings and stainless steel gasket saver before mounting the blower assembly on the blower housing. Review page 84 for isolation bushing specifics; and page 95 for gasket saver specifics. Position the blower assembly by sliding it into position on the five (5) mounting studs in the blower housing located on the front head of the GARN®. Hold the assembly in place and install the 3/8- 16 castellated nuts (those with teeth on one side). Tighten the nuts securely, compressing the motor mount gasket SLIGHTLY . 9. Manually rotate the blower wheel by hand. Access the wheel through the upper clean out. Ensure that there is no contact between the blower wheel and the blower housing. If there is contact, remove the blower assembly, adjusting the clearance between the blower wheel hub and the motor mount gasket, and repeat the assembly procedure.
