630 EUROSIT valves conform to all current safety standards. All operations of installation,
calibration, or regulation must be undertaken exclusively by qualified personnel following
the instructions specified in this catalog and those in the instruction manual of the
appliance in which this valve is installed. Any other operation should be avoided.
WARNING
This control is not field serviceable, all adjustments must be done in the O.E.M. factory.
Mechanical connections
General reccomendations: do not tamper with sealed parts. Do not loosen assembly screws. Do
not remove labels. Avoid shocks to the valve (impact, falls, etc.) Remove inlet/outlet dust caps
only at the time of installation. Do not exceed reccomended torque values. Ensure that gas
flow follows arrows on the valve body. Prevent foreign matter from entering the valve during
mounting. In particular, check that the inlet/outlet pipes are clean. Mounting of Eurosit is to be
done using the three mounting holes.
Main gas connection
The connection must be made using properly reamed pipes with 3/8” NPT thread. Apply a
moderate amount of a good quality pipe dope and apply 23 Lb./Ft. of torque. The multi-
functional control is provided with two main inlets and outlets. It is therefore necessary to
close the inlet and outlet which are not used, by screwing the provided plug fully in.
Torque 5.2 Lb./Ft.. Do not overtorque as this could cause distortion of pipe, leakage, and
or malfunction of control.
Pilot gas connection
Connect pilot gas tubing using proper 1/4” or 3/16” shear off nut and olive. Tighten finger
tight, plus one turn with a wrench to assure a good seal.
Thermocouple connection
Insert threaded end of thermocouple into control. Tighten the fixing nut finger tight, plus
1/4 turn with a wrench to assure a good electrical connection.
Testing
After all connections have been made, check all seals and gas connections for leaks, then
set the appliance into operation to assure it is functioning correctly.
