G96 Series CE Approved Gas Valve Installation Instructions 3
Wiring
!
WARNING: Risk of Shock.
Disconnect the power supply before making
electrical connections to avoid electrical shock or
equipment damage. Ensure that the operating
voltage is identical to the information on the product
identification label.
!
CAUTION: Risk of Equipment Damage.
For 12 VDC and 25 VAC applications, the ground
wire must not be connected to prevent possible
grounding of the 12 VDC power supply or 25 VAC
transformer secondary.
The G96 valve is supplied with 3-tab or 2-tab electrical
connections. The solenoid coils have male tabs, and
electrical connections should be made using 1/4 in.
(6.35 x 0.8 mm) female, fully insulated push-on
terminals. The earth ground is clearly labeled.
The electrical wiring to a twin solenoid valve from an
electronic intermittent proven pilot ignition system is
comprised of two lines; a common and an independent
earth ground. Wiring can be done using a single 4-wire
cable. The wiring connections for a 4-wire cable are
shown in Figure 4.
Route the electrical cable for the valve solenoid from
the burner sequence control to the valve and make
wiring connections in accordance with Figure 4.
Note: Electrical connections can also be made using
pre-wired electrical plugs (DIN 43650 Form B
[ISO 4400]).
All wiring must be in accordance with national and
local electrical codes and regulations.
Setup and Adjustments
IMPORTANT: All adjustments must be made in
conjunction with the gas appliance and in
accordance with the appliance manufacturer’s
instructions. Only authorized personnel should make
adjustments.
!
WARNING: Risk of Fire or Explosion.
The minimum flow rate of the valve must not be
adjusted below the minimum safe working rate of the
appliance.
The G96 valves have a right or left-handed top adjust
spring pressure regulator. Right or left-hand orientation
is determined by the position of the adjustment when
looking into the inlet connection of the valve.
The pressure regulator is adjusted from the top of the
valve when the valve is in the upright position
(solenoid coils on top).
The regulator controls the gas pressure at the valve
outlet by positioning the regulator poppet for selected
throughput flow and pressure. This is achieved by the
valve outlet pressure acting on the regulator
diaphragm, which balances against the preset
regulator spring. Adjustment of the spring compression
determines the valve outlet pressure and the
throughput flow rate.
To adjust the outlet pressure, remove the leak-limiting
seal cap to expose the adjusting screw (see Figure 3).
Turn the screw (using a suitable screwdriver) in a
clockwise direction to increase the pressure or in a
counterclockwise direction to decrease the pressure.
Repairs and Replacement
Field repairs must not be made to the G96 valve.
Any attempt to repair this assembly voids the
manufacturer’s warranty. For a replacement valve,
contact the original equipment manufacturer or the
nearest BASO Gas Products distributor.
