Just getting back into Factorio and downloading a few of my favorite mods. This is one of them and I got an error when increasing the Item Burn Rate to 1000 when changing my mod settings during new map creation:

Failed to load mods. Error while loading recipe prototype "item-stone-brick-incineration" (recipe): Difficulty normal: energy_required can't be <= 0.001.
Modifications: Flare Stack

Mods to be disabled:
*Flare Stack (2.2.6)

I deleted my mod-settings.dat and it loaded up fine for another try. I set the Item Burn Rate to 500 and it seems like it'll be okay. Just thought I'd let you know in-case there is a problem.

Thanks for the sweet mod!

Thanks for the heads-up, I'll have to add a minimum value to the config, or use the setting to change quantity burned rather than speed.

Is there a fix for this yet? Just ran into this same issue. Awesome mod btw really need it to work for my Bob's playthrough.

Sorry, I had a lot going on and missed this update. Fixed now.
