Chapter 2. MOUNTING WARNING Before mounting or removing, be sure to turn off the power to this device and all connected devices. Failure to do so may result in electric shock. If this device is installed near a source of ultraviolet rays other than the burner flame or in an atmosphere that interferes with UV rays, as described below, take sufficient countermeasures.
Chapter 2. MOUNTING What to know before installation • For proper installation of the device, thoroughly read the instruction manuals for the burner, boiler, and other equipment provided by the combustion equipment manufacturers. Make an appropriate instal- lation plan according to those instruction manuals. •...
Chapter 2. MOUNTING zRedundant system (redundant monitoring) Redundant monitoring is recommended to avoid unnecessary shutoff as much as possible and to ensure the reliability of the system. A re- dundant system can be made if two pairs of this device plus a burner controller are used to monitor the flame of one burner.
Chapter 2. MOUNTING zOutdoor use Provide a roof, etc., to protect against rain. Handling Precautions • The surface of the case may change color due to sunshine or other causes. However, this will not affect the functioning of the product. ...
Chapter 2. MOUNTING Handling Precautions • Mount this device so that it monitors the burner at an angle from above. If it monitors the burner at an angle from below or from the same level, dust, soot, etc., will accumulate on the monitoring window or in the monitoring pipe.

Chapter 4. ADJUSTMENT Pilot turndown test This test is intended to check that any pilot flame detected by this device will reliably ignite the main burner, even if the gas pressure and air pressure have changed to their worst possible conditions. WARNING To prevent explosion, carry out the pilot turndown test carefully.
Chapter 4. ADJUSTMENT (3) If the flame relay turns ON, adjust the monitoring point of this device to avoid effects from the ignition spark and its reflection. Handling Precautions • The following shows various sources other than flame that may activate this device. Check that the device’s operation is not affected by these sources under any operating conditions.
