Something interesting about this one is the very low CO level. We have not been able over the past 5 years to get the CO reduced by 90% over the baseline save in rare cases. This one nearly eliminates it.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>All in all it is not that great a design even if the performance looks good.
