4.4 Adjusting combustion differential air pressure switch

Combustion differential air pressure switch

The combustion differential air pressure switch monitors the pressure difference

generated by the burner fan.

LGW A2 ver. 2

Pos.

Item

Higher pressure

Lower pressure

Electrical connections

Adjustment wheel

1 and 2 Cross-head screw

If the pressure difference does not rise above the switch setting value, the burner will

shut down. The differential air pressure switch should be set to trigger before the CO

concentration in the flue gas exceeds 1 vol-% (10,000 ppm).
