5.
Attach the thermocouple securely to the pilot
burner, and screw the terminal end to the BASO®
power unit terminal on the valve. Make sure this
connection is clean. Tighten the thermocouple
lead nut finger tight, plus a maximum of 1/8 turn.
Do not overtighten.
6. Attach the pilot gas line to the pilot burner fitting
(if used) and to the pilot gas outlet of the H19
valve.
7. Check for leakage.
a. Shutoff 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 and indication of a leak.
To stop a leak, tighten joints and connection.
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

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 that
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. Test all joints and connections for leaks with a
rich soap and water solution. If leaks occur, see
Step 7 in the Installation section.
2. Close the main upstream shutoff valve and wait
at least 5 minutes for unburned gas to escape
from the appliance, and then reopen the valve.
IMPORTANT: When the reset button is
depressed, gas flows to both the main and pilot
burners on valves without the flow interruption
feature.
