5.5 Setting the max. gas pressure
switch
The burner is equipped with a max. gas pressure switch. It should block the
burner if the gas pressure exceeds the set value. Starting can then only take
place through a manual reset (burner control or gas pressure switch).
Setting the max. gas pressure switch
1. Remove the protective cover, screw (Y).
2. Open the pressure outlet and connect a pressure gauge to measure
the pressure downstream of the gas valve.
3. Connect the pressure gauge to the block (PBR or PA) or on the VPS
4. Start the burner.
5. Measure and make a note of the highest pressure downstream of
the gas valve within the range of the set output when the burner is
operating under normal conditions.
6. Based on the highest pressure measured downstream of the gas
valve, the desired pressure at which the burner must be stopped is set
downstream of the gas valve.
7. Set the max. gas pressure switch to this value by turning the scale.
The tolerance on the scale for the max. gas pressure switch is approx.
±15%.
8. Remove the pressure gauge and close the pressure outlet.
9. Fit the protective cover, screw (Y).
