Hi-- I d like to to install a Bosch 125HX on an outside wall, and vent through that wall. But my initial vertical height plus 45=B0 leg back through the wall (which counts as vertical) don't quite make the 6' vent height Bosch recommends. Is it a performance or safety issue with a shorter vent? I want hot water when the grid's down, so trying to make it work without powered vents! Thanks. --ian
