• Correct Rotation: 40-blade forward-curved cage, counter-clockwise (CCW) rotation as used in 8500 furnaces.
• Quiet Operation: Balanced for smooth airflow and reduced vibration.
• Direct Replacement: Sized to the factory housing depth and diameter—no universal guesswork.
• Durable Material: Molded composite wheel built for RV furnace temperatures.

Installation Notes

1. Disconnect 12V power and LP; allow furnace to cool.
2. Remove blower housing; loosen old clamp and slide off wheel.
3. Install the new wheel on the motor shaft; match the original depth so blades clear the housing.
4. Align the hub flat and tighten the clamp/set screw; verify free spin—no rubbing.
5. Reassemble and test airflow at registers; check for vibration.
