11. Remove all gas tubes from the standard valves and solenoid
valves as follows:
•
[Standard valves]:
Use a 9/16 inch wrench to remove the gas
tubes by unscrewing the hex nuts connected to the standard
valves. Be careful not to bend the gas tubes.
•
[Solenoid valves]:
Use a 1/2 inch wrench to hold the nut on a
solenoid valve, while unscrewing the attached gas tube hex
nut with a 9/16 inch wrench. Be careful not to bend the gas
tubes.

Gas Leaks
With electrical power off, carefully check for gas leaks at each gas
component that was removed, replaced, or otherwise serviced using a
gas leak detector (electronic leak detectors are highly recommended)
or bubble test.
