CAUTION
Installation, wiring, maintenance, inspection, and adjustment must be carried out by a
professional with technical training in combustion equipment and combustion safety.
Use this unit correctly within the range of the rated specifications stated in the user's manual.
Not doing so may cause device failure or malfunction.
Do not install this product in a place with any of the following characteristics.
• Certain chemicals or corrosive gases (ammonia, sulfur, chlorine, ethylene compounds,
acid, etc.)
• Splashing water or excessive humidity
• High temperatures
• Prolonged vibration
Wire this device correctly by using the wiring method, power, and installation method
specified in this user’s manual. Not doing so may cause device failure or malfunction.
Provide appropriate maintenance and inspection for the product, following the methods,
procedures, replacement cycle, etc., specified by this user’s manual.
When disposing of this device, dispose of it as industrial waste, following local regulations.
If timers and auxiliary relays are needed for additional functions, select ones with being
listed or component recognized by authorities, and be sure to design the circuit correctly.
Use this device within the operating ranges given in the specifications for temperature,
humidity, voltage, vibration, shock, mounting position, atmosphere, etc.
Make sure that the flame detector does not detect the ignition spark. If the ignition spark is
detected, change the position of the flame detector or ignition electrode.
For mounting and wiring, follow the instructions in this user’s manual or in manuals provided
by the combustion equipment manufacturer.
The ignition transformer ground must be directly connected to the burner itself or to metal
that is electrically connected to the burner.
Keep power wires and the ignition transformer high voltage cable separate from the flame
detector wiring.
Make sure that ignition transformer high-voltage cables are properly connected to prevent
faulty contact. Faulty contact can generate high-frequency radio waves, causing malfunction.
Connect the power supply last to prevent electric shock or damage. Otherwise touching
terminals by mistake may cause electric shock or may damage the device.
Always supply electricity at the voltage and frequency stated on the model label of this
device.
Make sure the burner frame is properly grounded complying with applicable local electrical
codes, ordinances and regulations.
