certified
by
AHRI. AFUE is
also know as Annual Fuel Utilization Efficiency or Seasonal Effic iency.
2.
!Net AHRI ratings are based on net installed radiation
of
sufficient quantity for the requirements
of
the building
and nOIIllng need be added 1o< normal pljMng and plcla.Jp. Rallngs are based on a piping and pickup allowance
" ' 1.15 and are determined under the piOII!sions gow>mfng forced draft boler·buroor units. An additional
atlowanoe should be made lor unusual p<plng and pickup loads.
