Opening Time:
Dead time maximum: 1 second.
First valve opening: less than 1 second.
Second valve opening: reaches 50% of the adjustable outlet
pressure within 5 seconds.
Maximum Allowable Leakage:
Outerwall: 3 cu. in./hr (50 cm3/h) at test pressure of 0.87 psi
(6 mBar) and 7.83 psi (540 mBar).
First Valve: 2.5 cu. in./hr (40 cm3/h) at test pressure of 0.87 psi
(6 mBar) and 7.83 psi (540 mBar).
Second Valve: 2.4 cu. in./hr (40 cm3/h) at test pressure of
0.87 psi (6 mBar) and 7.83 psi (540 mBar).
High Pressure Test:
In the OFF condition, the valve will withstand 21.75 psi (1.5 Bar)
inlet pressure without damage.

FL020008 Mesh Screen.
Flange Kits (see Table 2).
DIN43650 Connector
32006653-001 Venturi O-rings/screws.
Operational Voltage Range:
The combination gas valve will function satisfactorily between
85% and 110% of the rated voltage.
Gas Valve Connection to Venturi (Field-Assembled):
Four screws and an O-ring are used to connect the gas valve to
the venturi/manual shutoff valve.
The metal tube provided with the venturi must be connected bet-
ween the venturi and the gas valve regulator.
Fan Connection:
The venturi is connected to the fan using six bolts (wich are inclu-
ded with VMU).
Minimum Load:
The minimum load for which the system can be used is
14-17% of the reference load, which equals a minimum
pressure differential of 0.2 in. wc (50 Pa) of the 1:1
venturi/servo regulator gas control.
