* Notes:
All capacities are based on 180°F entering water temperature and 55°F entering air temperature. For other air and water inlet
temperature conditions, use the correction factors shown in Table 4 to multiply the given heating capacity for each size.
1 MBH = 1000 BTU/Hr. MBH Required = 0.00108 × CFM × Temp. Rise
