Smoke and CO levels may vary over time as the result of factors such as fuel chemistry, air

temperature, and combustion air contamination. To minimize soot production, and thereby help
assure continued efficient, reliable operation, observe the following precautions:
• Never leave the boiler in operation at a smoke level exceeding #1, even if this means that
the boiler must be operated at a CO
• Never leave the boiler in operation with a CO
if the smoke level at this CO
• In cases where field conditions are known to vary significantly, a good practice is to
provide a CO
the burner is left in operation. The size of this cushion depends on local experience, but is
typically 0.5% - 1.0%. For example, using a 1.0% cushion, if the burner reaches a #1 smoke
at 13.5%, the burner would be left in operation with a CO
The following procedure should be performed on a weekly basis:
For boilers equipped with a float low water cut-off, blow down the low water cut-off following the low water cut-off
manufacturer's instructions. 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 Hydrolevel CG450 low water cut-off - 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.
3) Allow the boiler to cool to room temperature and drain the boiler. Remove the 1-1/2" plug from the unused return tapping.
Use a flashlight to inspect the bottom row of pushnipples for accumulated scale or mud. If a significant amount is present, use
the following procedure to clean the inside of the heat exchanger:
