2. If flame is unsatisfactory at either high fire or low fire, check
combustion values. If combustion is properly adjusted, turn
off boiler and allow boiler to cool down. Then remove burner
and clean it thoroughly using a vacuum cleaner or compressed
air. Do not use compressed air to clean burner if performed
inside a building.
3. To access the burner, remove the heat exchanger cover plate
following the procedure beginning on page 108.
4. If replacing the burner, ensure the burner gasket is in good
condition and correctly positioned. Follow all instructions
on page 109 to reinstall all components.
5. Restart the boiler.
6. Inspect the flame at high and low fire. If flame is still not ac-
ceptable, check combustion values. If combustion is properly
adjusted, obtain a replacement burner from Weil-McLain.
