Heatilator CD4236IFTLR: Battery backup not working

[epstauffer]

I discovered that my propane fireplace (Heatilator CD4236IFTLR) has a battery backup for power outages. I'd like to use the feature. I installed 4 AA batteries, cut the breaker, flipped the switch- nothing.

I took some (bad) pictures of the wiring, not sure if this tells any kind of a story: Pics here

Any advice?

Did you check the voltage output of the batteries?

Check the spade connectors between the back up tray and the wiring harness. I have found these to appear connected, but the male and female spades were not engaged inside the protective plastic ends.

Check the battery voltage as Daksy mentioned.
