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.
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 H19
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. Perform the Checkout section before leaving the
installation.
