XII Service and Maintenance

The following procedure should be performed on a weekly basis:

For boilers equipped with a #67 low water cut-off, blow down the low water cut-off following the instructions on the yellow sticker adjacent to the low water cut-off. During this blow down, the low water cutoff should shut down the burner. If it does not, the low water cut-off should be replaced immediately.

The following procedure should be performed on an annual basis:

1)Turn off electrical power and oil supply to the boiler.

2)Inspect the low water cut-off:

•For Hydrolevel CG450 low water cut-offs - Remove and inspect the probe for scale and sediment buildup. Clean any sediment or scale from the probe with a scouring pad or steel wool. Consult the Hydrolevel CG450 manual for any additional maintenance information. Test the low water cut-off before placing the boiler back into service.

•For McDonnell & Miller #67 low water cut-offs - Remove and inspect switch and float mechanism. Inspect float bowl for mud accumulation. Clean as required. Replace the switch and float mechanism every five years or 100,000 cycles. Consult the McDonnell and Miller #67 manual for any additional maintenance information. Test the low water cut-off before placing the boiler back into service.
