CAUTION
Do not connect a load that exceeds the rating stated in the specifications to the control load
terminals (6, 7, 8), and do not short-circuit the load. Doing so will burn out the internal fuse,
making this device unusable.
The protection rating of this device is equivalent to IP10 or IP40. According to equipment
requirements, install this device in a control panel with appropriate protection rating.
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 may generate high-frequency radio waves, causing
malfunction.
Always supply electricity at the voltage and frequency stated on the model label of this
device.
Make sure the burner frame is properly grounded in compliance with applicable local
electrical codes, ordinances, and regulations.
The pilot turn-down test should be carried out only by an experienced specialist possessing
knowledge and skills pertaining to combustion equipment and combustion safety.
If the combustion equipment is restarted as a result of a lockout, do all of the inspection steps
described in
Chapter 5, “Trial Operation and Adjustment.”
When doing a maintenance inspection of the burner, be sure to do the pilot turn-down test.
Inspection must be done at least once a year.
Inspect the combustion equipment periodically in accordance with the instructions given in
the manual provided by the equipment manufacturer.
When cleaning the burner, clean the flame detector also.
When transporting or storing this device, temporarily remove it from the sub-base and pack
