be at the 135,000 Btu/hour rate using multiple smaller units since that is what the standard 90.1 provides for. i.e. the baseline system wouldn’t turn out to be one that wasn’t given an efficiency, even if the proposed case fell outside the 6.8 bounds.<o:p></o:p></span></p>

<p class="MsoNormal" style="background:white"><span style="font-family:HelveticaNeue;color:black">I’d fall back to 6.4.1.1 under the mandatory provisions for the prescriptive compliance path – that’s the section citing the 6.8 series tables for the purpose
of establishing prescriptive compliance. As I’m reading/interpreting, equipment that is not listed categorically within the 6.8-series tables by extension does not need to achieve any minimum performance rating. There is however some complementary text there
you’ll want to review carefully to see if anything applies to your situation.<o:p></o:p></span></p>
