Pump | With pump operating, check for excessive vibration or noise. Vibration is usu- |
| ally a sign that the impeller is out of balance. Turn off the system, insure |
| power is shut off and remove the inlet plate. Check the shaft seal and replace |
| it if worn or missing. |
| With the Power off: |
| Check the inlet and outlet of the pump for blockage or excessive soot and |
| clean as necessary. |
| Check boots for cracking or deterioration and replace if necessary. |
| If a condensate trap is installed, check the condition of the trap and the drain |
| line attached. Note: the condensate trap should be filled with water at the |
| beginning of each heating season. |
| Check the condition of the motor mounts. Lift the motor from the rear; look for |
| breaks in the rubber and replace if necessary. |
