In larger sizes, this is available. https://www.bosch-climate.us/files/201309192156100.6720646836_GB162_Flue_Cascade_Kit_Installation_Instructions_en-fr_08.2013.pdf0

I stand corrected.
I like the first thing listed on the second page:
" To be installed by a heating engineer only." I wonder why.0 -
In our gas code, only the same make, model and capacity, plus each unit must have a factory installed backdraft prevention device can be combined vented.
Most NA manufacturers have followed our recommendations.

I'm not a Navien guy so I can't say for sure, but I have seen a whole lot of Navien units piped to a common vent when cascaded.0
