GENERAL INSTRUCTIONS
UV-Detector
This should not be exposed to tempe-
ratures exceeding 60°C. The current
passing through the UV-detector,
when it is being illuminated, should be
at least 70 µ A for LFL1.. This current can
be measured by means of a moving
coil instrument. Checks should only
be made if a fault is suspected.
The capacitor, which sould be placed
between the terminals on the moving
coil instrument, must be of
100 µ F 10-25 V.
Gas pressure switches:
Adjustment range:
2,5-50 mbar GW 50
5-150 mbar GW 150
Adjustment of min. gas pressure
switch
The min. pressure switch should react
if the gas pressure is too low and
prevent the burner from starting. Too
low a gas pressure during operation
should stop the burrner. The burner
may start again when the rated gas
pressure has been reached.
Remove the protective cover. Con-
nect a pressure gauge for measuring
the rated pressure. Decide on pressure
at which the gas switch should switch
off. Set this pressure by means of the
valve. Carefully turn the knob (see
igure) until the gas pressure switch
switches off. The value shown on the
scale should then approximately cor-
respond with the value shown on the
pressure gauge. Tolerance on scale
appr. ± 15%. Open the ball valve.
Adjustment of max. gas pressure
switch
The burner is equipped with a max.
gas pressure switch only on request.
It should stop the burner if the gas
pressure exceeds the set value. The
burner can then only be re-started
manually (gas burner control or over-
pressure switch).
Remove the protective cover. Connect
a pressure gauge for measuring the
rated gas pressure. Decide on pres-
sure at which the gas pressure switch
should switch off. Turn the adjustment
knob to this value. Tolerance on the
scale ±15%.
Adjustment of air pressure switch
The air pressure switch should
stop the burner if the air volume is
reduced.
On adjustment, turn the scale on
the air pressure switch in clockwise
direction. When the switch-off point
has been reached and the burner
stops read off the value on the scale.
Then turn the scale in anti-clockwise
direction to desired value. Make
repeated start attempts to ensure
that the air pressure switch is not too
closely set.
