2 G292 Series BASO Dual Pilot Gas Valve Installation Instructions
!
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.
!
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.
6. Check for leakage:
a. Close the main upstream manual shutoff valve
and open the pressure connection between
the manual shutoff valve and the G292 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.

WARNING: Risk of Explosion or Fire.
Follow this or an equivalent checkout procedure
after installation. Before leaving the installation,
verify that the gas valve functions properly and the
system has no gas leaks. Gas leaks can lead to an
explosion or fire, and may result in severe personal
injury or death.
Make sure all components are functioning properly by
performing the following test:
1. Open all upstream shutoff valves and test all joints
and connections of leaks with a soap solution.
2. Close the main upstream shutoff valve and wait at
least five minutes for unburned gas to escape from
the appliance, and then reopen the shutoff valve.
3. Push the reset button of the inlet (first) BASO
power unit and light the pilot burner (see Figure 1).
Continue to hold the reset button for 30 to
45 seconds or until the pilot remains burning when
the reset button is released.
4. Push the reset button of the outlet (second) BASO
power unit and light the pilot burner (see Figure 1).
Continue to hold the reset button for 30 to
45 seconds or until the pilot remains burning when
the reset button is released.
Note: If control thermostats for each burner are not
used, gas will flow to both main burners, igniting each.
5. Set the thermostat for the first main burner to the
highest setting. It should ignite from the pilot
burner.
