BEopt Error: Cannot model a water heater without hot water distribution.

I am modeling a multifamily building retrofit. Existing building has a central gas water heater, retrofit has individual HPWH in each unit. I keep getting this error when I try to run the model. I've tried different HPWH options and different distribution options and always get the same error. Has anyone seen this before? Is it not possible to switch from a central system to a distributed system?
