E-9 DISPLAY

Displayed at the finish of
Forced burning timing.

Explanation 1
In the timing (150 seconds) of the forced burning, the Heater compulsorily gives High burning after the finish of the
forced Med.-High burning until an electric current of the Secondary Flame Rod of higher than 0.3 µA is detected for
longer than 2 sec.

Explanation 2
See Explantion 7 of E-6 Display.

Explanation 3
See Explanation 1 of E-8 Display.

Explanation 4
Make sure that the Secondary Flame Rod is in proper position and free of touching the outer tube on the
earthing side.

Explanation 1
If the Incomplete Combustion Preventive Device is used in an enclosed room for a long time of period, the
oxygen in the room will be short of oxygen in a level of O

2

vol. % = approx. 18%, to stop the operation.

This Heater reads the temperature (by resistance) of the Burner Thermistor at twenty minutes after the starting
operation and determines operation setting level, at the same time.

The temperature (by resistance), room

temperature change, and the coefficient for combustion condition are calculated and monitored by micro-
computer.
Explanation 2
Check to see if there is any loose screw for the Burner Thermistor. Apply the end of the Burner Thermistor with
an adhesive and securely fasten the Thermistor.

Since the lead wire is thin and, therefore, easily breakable, sufficient care is to be taken not to twist it.
The reference resistances of the Burner Thermistor are shown in the following table.
Since this thermistor is different by a model, use that which suits the model.
