Operation Sequence

1. Combustion fan purges heat chamber, PCB

verifies fan rotation

2. Ignition spark begins

3. When sensing electrode detects spark, gas

valve assembly opens

4. Ignition occurs and heat exchanger warms

5. Spark stops as flame rod & PCB verify flame

6. When heat exchanger is warm enough,

convection room blower circulates warm air

into the structure.

7. When filled, the humidifier tray ensures the

air is not too dry (if needed)

8. Thermistor & PCB determine gas and fan

settings

9. When temperature set point is

reached, if needed, gas valves close &

combustion fan stops. Convection fan

continues to run to cool down unit.

10.When temperature drops, process starts over
