CAUTIONS
Must be observed to prevent equipment damage or loss of operating
effectiveness.
CAUTION
Many 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.
CAUTION
DO NOT use this heater if any part has been under water. Call a qualified service
technician to inspect and replace any part that has been under water.
1.2 EMERGENCY SHUTDOWN
If overheating occurs or the gas supply fails to shut off, close the manual gas shutoff valve (Figure 1-1)
located external to the unit.
IMPORTANT
The Installer must identify and indicate the location of the emergency shutdown manual
gas valve to operating personnel.
1.3 PROLONGED SHUTDOWN
After prolonged shutdown, 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 AERCO heater and close
the manual gas valve located upstream the unit. The installer must identify the emergency shut-off device.
