7. THERMOSTAT SETTING
SETTING
The thermostat must be set for an individual appliance at the factory.
However, if necessary an authorise person can recalibrate as follows:
♦ Remove knob 1
♦ Remove nut 2 and 7mm hexagonal spanner
♦ Operate the appliance until an oven temperature of 200°C is reached (or 160°C for a
fryer)
♦ When the appropriate temperature for the appliance is reached on test thermometer,
slowly rotate Pawl 3 towards the “OFF” position until the main burner snaps off.
Remove Pawl 3 from the splined adjusting screw and relocate so that when Knob 1 is
replaced the correct temperature mark on the Knob 1 corresponds to the oven (or
fryer 0 temperature.
♦ All components are re-assembled in the reverse order.
LOW FIRE ADJUSTMENT
Low fire is regulated by means of the “Min” screw only when the thermostat bulb
temperature is within the range of the control.
• Turn knob 1 to “OFF” position and remove
• Remove the cover by loosening the two fixing screws
• Turn Pawl 3 slowly until the instant that the valve snaps open to give minimum flame
on the main burner]
• To reduce the flame - turn “Min” screw in clockwise direction
• To increase the flame - turn “Min” screw in anticlockwise direction
• The correct flame is achieved when the burner will ignite from the pilot and extinguish
without noise and without burning back on the injector.
• Replace cover and knob 1 in reverse order.
PILOT GAS ADJUSTMENT
• To reduce pilot flame turn “Pil” screw clockwise
• To increase pilot flame turn “Pil” screw anticlockwise
• The pilot flame should be adjusted in conjunction with the air shutter provided on the
pilot to achieve a firm stable flame impinging on the tip of the thermocouple (the last
5-7mm).

8. THERMOSTAT SETTING Cont’d
INSTALLATION
630 EUROSIT complies with current safety standards.
Nevertheless, its installation on appliances must be verified in accordance
with specific standards for each installation. In particular, it is necessary
to ensure that requirements relating to the class of flame failure device are
met. All the installation, setting and adjustment operations must be carried
out exclusively by qualified personnel on the basis of the specific characteristics
of the appliance. The valve is not for outdoor use.
MECHANICAL CONNECTIONS
General recommendations
Do not tamper with sealed parts. Do not slacken assembly screws. Do not remove
labels. Avoid blows (knocks, falls etc.). Only remove dust caps when installing.
Do not exceed recommended torques. Ensure that the gas flows in the direction
shown by the arrow on the valve body. Prevent foreign matter from getting into the
valve during installation. In particular, check the cleanliness of the inlet and outlet pipes.
Do not subject the valve to bending in excess of 35 Nm and to torque in excess of 25Nm.
Use only the specified spanner grips when making the connections. The valve has three
pairs of retaining holes.
Main gas connection
The connection must be made using gas pipes with Rp 3/8 ISO 7 thread. Torque 25Nm.
Alternatively, it is possible to use nut and olive connections for Ø12mm pipe (code
nos.0.958.025 and 0.957.007) (torque 15 Nm) The valve has two main gas inlets (10
and 12) and two outlets (11 and 13). The outlets which are not used must be sealed by
screwing the special plug (code 0.972.061) in flush Torque 7 Nm.
Connection to pilot burner
Ø4mm, 6mm and ¼” pipes can be used. Use appropriately sized nut and olive. Tighten
to 7Nm torque. After making the gas connections, check seals and ensure appliance
works properly.

10. FAN FORCE
FAN SWITCH
NEEDS TO BE ON ALL
TIME WHEN OVEN IS
USED
SPARKER
Fan Forced Ovens allow a more even cooking of the product due to the air circulating
more freely in the oven and the air movement helps to strip away thin layers of
moisture and cool air from around the product allowing the heat to penetrate and
reduce cooking time.
The fan should always be running when the oven is in use if under unusual
circumstances
the fan can be switched off if the oven temperature is set less than 160ºC.
The warranty on the fan is void if it is not used in temperature over 160ºC.
