Chapter 5. MAINTENANCE AND INSPECTION
■
Inspection cycle
Determine an inspection cycle taking into consideration the following factors:
• Type of equipment
• Ambient conditions of installation site (dust, temperature, etc.)
• The effect of burner failure on equipment operation.
1. Carry out the safety shutoff test described in
Chapter 4, AD J USTMENTS
FOR TRIAL OPERATION
once per month.
2. Inspect the monitor window on the ultraviolet flame detector, the flame rod, etc.
for dirt, and clean as necessary.
3. Check the temperature where the ultraviolet flame detector is installed.
4. Measure the flame voltage at least once per month to check its state. If
equipment will be seriously damaged by a burner failure, carry out this
inspection more frequently.

WARNING
Before removing or mounting the FRS100, be sure to turn the power OFF.
Failure to do so might cause electric shock.
Do not touch the terminals on this control. Doing so might result in an electric
shock.
Do not touch terminal F or the flame detector cable connected to terminal F.
Failure to pay attention to this warning might cause electric shock. An
electric charge remains the terminal F and the connected signal cable even
after the power is turned OFF.
CAUTION
Mounting, wiring, maintenance, inspection and adjustment should be carried
out by a specialist who has been trained in how to handle burners and
combustion safeguard controllers.
When the controller is restarted after the safety shutoff, check all items
described in
Chapter 4, ADJUSTMENTS FOR TRIAL OPERATION
.
Before carrying out maintenance and inspection on the burner, be sure to
carry out the pilot turndown test. Carry out this test at least once every year.
Periodically maintain and inspect the equipment as instructed in the
equipment manufacturer’s user’s manuals.
When cleaning the burner, also clean the flame detector.
