On Demand Pilot (seven day safety timer)
Important information if using the appliance in CPI (continuous pilot mode) only
This appliance is a Dexen control system fitted with the “On Demand” Pilot, a safety feature which will shut down the gas valve completely by extinguishing the
pilot light in the event of a continuous full seven days of inactivity.
This only applies if the CPI (continuous pilot) switch is in the “on” position in your remote control transmitter.
Each time the main burner shuts down, manually or through the call from the thermostat, the seven day timer starts again.
The seven day inactivity timer is controlled within the circuit board. Therefore, if in CPI mode and when the pilot light is extinguished after seven straight days
of inactivity, the CPI setting on the remote control transmitter will remain in the “CPI” (continuous pilot) position. Therefore, all that is required to relight the
pilot would be to press the on/off button on the remote control transmitter from “on” to “off” and back to “on”. Once the pilot has re-established operation will
resume as normal. There is no requirement to do anything with the IPI/CPI mode on the remote control transmitter.
If the unit never goes as long as seven full days without a call for heat, the pilot will remain lit until it is manually shut-off.
If the unit is being operated in IPI (intermittent pilot) mode, neither the above instructions nor the seven day timer will apply.
See the instructions in this manual and on the Lighting Instructions plate on the appliance to light or re-light the pilot.
