I'm not sure, never having made a sand incubator, but as you need air flow anyway, could you just install a fan to blow air out and turn up the heat?

Sorry if this isn't helpful,and I know it's a little late.
@Pyxis or @BantyChooks or @Sally Sunshine might know, though.

Good luck and Welcome to BYC!

it has a vent on top in the diagram plus you will be opening the door to turn the eggs right? that should let out enough co2. it's not like the incubator is sealed air tight.
