INSTRUCTIONS FOR USE

To turn the valve on, simultaneously press and turn the control shaft. Holding down the control shaft and
turning it anti-clockwise allows the gas to pass to the burner. A few seconds after the burner ignites, the
thermocouple generates enough current to hold the safety magnet open. The control shaft needs no longer be
pressed down.
If indicated in the assembly drawing, to turn the valve on is necessary, starting from the close position (0°A), to
turn the operating spindle anti-clockwise up to 90°A; only in this position the safety valve can be opened and
consequently is possible to held-on the magnet.
If the valve has a microswitch, press down on the control shaft activating the microswitch which drives the
thermoelectric lighting device (see table 1).
Maximum flow-rate is reached after turning the control shaft through 90°; reduced flow-rate is reached by
continuing the rotation up to 210° (160° mod 46R – 290° mod 46M).
If the flame should accidentally go out, the thermocouple cools and the current is reduced, the safety magnet
is closed and the flow of gas is blocked after a few seconds.
The valve has an adjustable perforated metering screw (by-pass) which fixes the reduced flow-rate at a preset
value when fully tightened. If a different type of gas is used, the amount of reduced flow can be adjusted by
turning the by-pass with a screwdriver.
