Mjshakl, I double checked my statement re the flue pipe on the CFCL website and have now confirmed that the Bluegen unit does have a balanced flue which reduces considerably the amount of natural ventilation the unit needs to operate efficiently.If you are curious about how these flues work you could visit the Rinnai website (Rinnai is owned by Paloma who has an agreement with CFCL)and look at the Infinity internal gas fired water heater which uses a balanced flue.They are quite ingenious.
