Bosch POWER VENTING SYSTEM

B.The Air-Flow Adjustment on the Power Venter is factory set for optimum air flow. Operating at its setting will assure that combustion gases are safely removed to the outside.

MAINTENANCE

Points of inspection are:

1.Motor - Motor must rotate freely.

2.Fan Wheel - Wheel must be clean of dust or any other coating which inhibits rotation or air flow. Remove all foreign material from vent system before operation.

3.Spill Switch - Verify proper spill switch operation by observing Operation Sequence and by temporarily blocking termination outlet.

4.Check Draft - Check for flue gas spillage following steps in the Operation And Checking Draft on page 9.

5.Vent Termination - Inspect to ensure installation and clearances have not been altered or obstructed and that the back draft flapper (when used) movement is free and operational. Note that terminal hood is removable for easy flapper maintenance or replacement.
