When the Control Box ON/OFF switch is set to the ON position, it checks all pre-purge safety
switches to ensure they are closed. These switches include:
•
Safety Shut-Off Valve Proof of Closure (POC) switch
•
Low Water Level switch
•
High Water Temperature switch
•
High Gas Pressure switch
•
Low Gas Pressure switch
The Blocked Inlet and downstream Blower Proof switches are not
checked prior to starting the pre-purge.
If all of the above switches are closed, the READY light above the ON/OFF switch will light and
the unit will be in the Standby mode.
When there is a demand for hot water, the following events will occur:
If any of the Pre-Purge safety device switches are open, the appropriate
fault message will be displayed. Also, if the required conditions are not
observed at any point during the start sequence, appropriate messages will
be displayed and the unit will go into fault mode.
