5.1.5 Setting gas pressure switch min
The min. switch should react to a gas pressure that is too low and prevent
start of the burner.
Too low a gas pressure during operation should stop the burner. The burner
can start again when the nominal gas pressure has been corrected. Remove
the protective cover. Connect a pressure gauge for measuring the nominal
pressure. Determine the pressure at which the gas switch should break
according to current local standards; if nothing is indicated, lower approx.
20%. Set this pressure with the ball valve. Carefully turn the knob (see fig.)
until the gas pressure switch breaks.
The value on the scale should then approximately correspond to
the pressure gauge reading. Tolerance on the scale approx. ± 15 %. Open
the ball valve.
5.1.6 Setting gas pressure switch max
(Accessories)
The gas pressure switch should block the burner if the gas pressure exceeds
the set value. Starting can then take place only through manual resetting
(gas burner control or gas pressure switch).
Remove the protective cover. Connect a pressure gauge for measuring
the nominal gas pressure. Check the function of the pressure switch by
slowly turning it down until it breaks. Determine the pressure at which the
gas switch should break according to current local standards; if nothing is
indicated, increase 20%. Turn the wheel to this value. Tolerance on the scale
±15 %
