Performance Data
300-Heating (0.45 ESP)
Table P-51: GEV 300 Heating Performance
Performance data is tabulated for heating at 68 F DB entering air at ARI/ISO 13256-1 rated CFM.
For conditions other than what is tabulated, multipliers must be used to correct performance. See the fan correction factors Table for CFM
other than rated and the heating correction factors for variations in entering air temperature. Data shown in bold type is performance data
at ARI/ISO 13256-1 WLHP and GLHP water only conditions. Antifreeze correction factors may be found on page 108.
RATED ESP (in. H20): 0.45 RATED GPM: 75.0 MINIMUM CFM: 8000
