Settings And Adjustments; Important Warning - Sit 810 ELETTROSIT Manual De Instrucciones

SETTINGS AND ADJUSTMENTS

All the adjustments must be made on the basis of the
specific characteristics of the user appliance. Check the
inlet and outlet pressures at the provided test points, and
G
. After testing, seal the test points using the provided
H
screws. Recommended torque: 2.5 Nm.
Adjustment of the gas flow to the pilot ("PILOT ADJ"
adjustment screw)
To reduce flow, turn the "PILOT ADJ" screw clockwise.
To increase flow, turn the "PILOT ADJ" screw anticlockwise.
Adjusting the outlet pressure ("REG ADJ" adjustment screw)
Remove the protective plastic cap. To increase the pressure, turn the "REG ADJ" screw clockwise. To decrease the
pressure, turn the "REG ADJ" screw anticlockwise.
Adjustment of minimum flow for slow ignition with natural gas ("I STEP ADJ" adjustment screw)
System no. 1
Turn the "REG ADJ" screw completely anticlockwise. Adjust the "I STEP ADJ" screw until the burner ignites in a gradual
and silent manner. Adjust the "REG ADJ" screw to obtain the desired outlet pressure. Seal the "I STEP ADJ" and "REG
ADJ" screws.
System no. 2 (To be used when the pressure regulator has already been set and the "REG ADJ" screw is sealed)
Turn the "I STEP ADJ" screw completely clockwise. By trial and error, adjust the "I STEP ADJ" screw (each time, turn it
about 1/4 turn anticlockwise). After each adjustment, pass to the pilot position by pressing the button ; wait 30-60 s
and return to the "operation" position by pressing the cross button . When the minimum flow which ensures slow
and gradual burner ignition has been determined, seal the "I STEP ADJ" screw.
NOTE: on request, the "I STEP ADJ" screw can be provided with a calibrated hole. In this case it must be screwed fully in.
Adjustment of minimum flow for slow ignition with LPG ("NO PR" override screw)
Remove the protective cap and check that the "NO PR" screw is turned completely clockwise until it stops. Adjust the
"REG ADJ" screw to obtain an outlet pressure of about 12 mbar. Turn the "NO PR" screw completely anticlockwise until
it stops. Adjust the minimum flow for slow ignition using the system no. 2 described above. Turn the "PILOT ADJ"
screw completely anticlockwise. Seal the "I STEP ADJ", "REG ADJ" and "PILOT ADJ" screws.

IMPORTANT WARNING

The "NO PR" override screw must absolutely never be left in an intermediate position: it must be screwed fully in for
normal operation with town gas and natural gas, and unscrewed completely until it stops for use with LPG.
