The interesting thing is that this lockout timer isn't needed for the
non-propane gas burners. Propane, apparently, is different that way, for a
reason I'm still trying to ascertain.

But, here's one description of what it does:

http://xpedio.carrier.com/idc/groups.../58se-11si.pdf
During normal operation, if the pilot flame is not proven within approximately
*30 seconds*, the lockout timer opens, de-energizing the gas valve and stopping
the gas flow to the pilot. The lockout timer will remain open until it is
manually reset".

Notice the time period is hugely different in this document:
http://xpedio.carrier.com/idc/groups...0394dp40-a.pdf
"During normal operation, if the pilot flame is not proven within approximately
*5 minutes*, the lockout timer opens, deenergizing the gas valve and stopping
the gas flow to the pilot. The lockout timer will remain open until it is
manually reset".

In summary, the lockout timer apparently shuts the system down if the pilot
flame isn't proven in the allotted time frame.
