11. Pilot gas connections.
Internal Pilot Gas Valve Models receive pilot
gas internally from the valve body.
Note: Pilot gas flow comes out of either gas
valve top housing ports.
On internal pilot gas valve models, plumb the
pilot burner fitting to either of the pilot gas
ports on the valve. Plug the unused pilot gas
port on the gas valve.(see Figures 4 and 5).
External Pilot Gas Valve Models receive
pilot gas from an external gas source.
Note: Pilot gas flow through the gas valve top
housing can be in either direction as indicated
by the arrows.
On external pilot gas valves, plumb the pilot
gas line from an external gas source to either
pilot gas port on the gas valve. Plumb the
other pilot gas port to the pilot burner
fitting.(see Figure 6).
!
WARNING: Risk of Explosion or Fire.
Never connect an external gas line to an internal
pilot gas model. Pilot gas would flow freely in one
port and out the other, which could lead to an
explosion or fire and may result in severe personal
injury or death.

G92 Model Rev. B Series BASOTROL® Automatic Pilot Gas Valve
!
WARNING: Risk of Explosion or Fire.
Verify that there are no gas leaks by testing with
appropriate equipment. Never use a match or lighter
to test for the presence of gas. Failure to test
properly can lead to an explosion or fire and, may
result in severe personal injury or death.
12. Check for leakage:
a. Close the main upstream manual shutoff valve
and pilot adjust (applications with a pilot adjust)
and open the pressure connection between the
manual shutoff valve and the G92 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.
