CHAPTER 1 – SAFETY PRECAUTIONS
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.
• 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.
Figure 1.2: Manual Gas Shutoff Valve
1.3 PROLONGED SHUTDOWN
After prolonged shutdown, it is recommended that the initial startup procedures in Chapter 4
and the safety device test procedures in Chapter 5 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.
