BASO G96 Series CE Approved Gas Valve - Manual (Page 2)

2 G96 Series CE Approved Gas Valve Installation Instructions
6. Use an approved pipe joint sealing compound on
the male threads before assembly. Remove
excess compound after mounting the valve to the
pipework. Threads of the pipe and nipples must be
smooth and free of tears and burrs. Steam clean
all piping to remove foreign substances such as
cutting oil or thread chips.
7. Check for leakage.
a. Shut off the gas at the main manual shutoff
valve and open the pressure connection
between the manual shutoff valve and the
G96 valve.
b. Connect air tubing with a maximum pressure
of 1-1/2 times the valve’s maximum operating
pressure (as indicated on the valve) to the
opened pressure connection.
c. Paint all valve body connections with a rich
soap and water solution.
If bubbles occur, this is an indication of a leak.
To stop a leak, tighten joints and connections.
Replace the part if the leak cannot be stopped.
If bubbles do not occur, remove the air tubing
and close the pressure connection.
8. Make wiring connections. Refer to the Wiring
section for specific wiring instructions.
9. Determine the outlet pressure by applying power
to the valve and energizing both valve solenoids.
Use the outlet pressure tap connection on the
underside of the valve body to monitor the outlet
pressure. The outlet pressure tap is a bleed hole
with a cast spigot, sealed with a threaded brass
needle screw (Figure 2). To monitor the outlet
pressure, turn the screw in a counterclockwise
direction one or two turns and fit a 9 mm diameter
flexible tube over the cast spigot. After all valve
adjustments have been made and the desired
outlet pressure has been obtained, remove the
flexible tube. Tighten the needle screw by turning
it clockwise with a slotted screwdriver until hand
tight, sealing the bleed hole.
10. Check for leakage at the bleed hole. Paint the
bleed hole with a rich soap and water solution (or
use acceptable gas leak detection equipment). If
bubbles occur, this is an indication of a gas leak.
To stop a leak, tighten the needle screw. Replace
the valve if the leak cannot be stopped.

11. If necessary, set the valve to the desired outlet
pressure. Refer to the Setup and Adjustments
section for specific adjustment procedures. After
making valve adjustments, ensure that the leak-
limiting seal cap is tight. See Figure 3.
12. Before leaving the installation, observe at least
three complete operating cycles to ensure that all
components are functioning correctly.
