blast furnace multiblock wont work how many times i do it i watched videos read guides nothing works i tried rotating it i tried doing it in 1 chunk only i tried different dimensions i tried different tiers of casings i tried with lava and with air but none of them worked.

Steps to reproduce the behavior:
-make a 3x3 machine casing behind a blast furnace and add a another 3x3 on top of it but with a hole in the middle with lava and another 3x3 with a hole and with lava and make a final 3x3 and give it energy.TLDR:just build the multiblock.
-try to start the machine
