3.8.4 Flame Sense Rectiﬁcation

The Evolution Gas Steamer utilizes a ﬂame sensing circuit to

determine if the system has proper combustion. When the

system is turned on, gas is sent to the burner and an electronic

ignition tries to ignite the burner. The ignition module then

checks to see if ﬂame is established in the burner.

If the ﬂame sense feedback is within the proper range the

system will stay on until the pressure switch opens. The ignition

module continues to monitor the voltage and as long as its

within the proper range the burner will stay on. If the ﬂame

sense reading falls below the threshold of 2.5uA (microamperes)

the steamer will go into lock out and will stop heating. There is

no exterior signal for a lockout.

1. The ﬂame sense should be monitored and recorded as part

of the install.

2. To test for ﬂame sense, connect a multimeter to the FC+

and FC- pins on the ignition module (FIGURE 8). Set the

multimeter to test for microampere.

3. Run the unit and monitor the reading.

4. If the gas pressure is set correctly for the gas type the

reading should be 4 to 6 µA (Micro Ampere)

5. The air intake shutter is factory set to a value of 2.5 to 5.The

gap has been pre-set at the factory for best combustion

performance (FIGURE 9).
