 Many of the soaps used for gas pipe leak testing are corrosive
to metals. The piping must be rinsed thoroughly with clean
water after leak checks have been completed.

qualified service technician to inspect and replace any part that
has been under water.
1.2 EMERGENCY SHUTDOWN

1.3 PROLONGED SHUTDOWN
After a prolonged shutdown (one year or more), it is recommended that the startup procedures
in Chapter 4 and the safety device test procedures in Chapter 6 of this manual be performed to
verify all system-operating parameters. If there is an emergency, turn off the electrical power
supply to the unit and close the manual gas valve located upstream of the unit. The installer
must identify the emergency shut-off device.
