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.
