7.1.3  Purging 

1.  All switches required to be met during the purge cycle (as shown above) have a checkbox, 

which changes to green once the switch is met.  If any switch fails to be proven, its 
checkbox will turn red with a white X and the unit will display a fault message explaining the 
failure. The safety circuit switches are:  

•

  Blower Proof 

•

  Purge Position  

•

  Blocked Inlet 

•

  Ignition Position 

 

 

Figure 7.1.3: Ignition Sequence - Screen 3, Purge 

2.  The following additional parameters are displayed:  

•

 

Purge Timer

: The purge cycle

’s elapsed time in seconds 

•

 

Valve Position Out

: The

 Air

 Fuel Valve

’s position 

•

 

Blower Voltage

: The blower voltage as the unit purges 

3.  Upon expiration of purge timer, if all the switches are met, the 

Purging

 rectangle turns 

green and the system progresses to 

Spark Cleaning

. If the purge timer expires before all
