To view and confirm Postpurge timing refer to the Commissioning page (see Fig. 65)
or in the BC Diagnostics page (see Fig. 78) for locations in the menu system. The
Commissioning page can only be viewed when the Burner Control is in an appropriate
state to permit commissioning. If it is in that state, current commissioning settings can be
viewed without actually starting the commissioning process.
