Notes (V-Series):

  1. Motor ratings for gas only or gas/oil burners using a remote oil pump
  2. Motor ratings for oil only and gas/oil burners using a direct drive oil pump
  3. Remote oil pump is optional for frame size 1 and 2 but standard for frame sizes 3 and 4. All pump motors are 115/230/1
  4. Low/High and Full Modulation minimum gas pressure
  5. Lower gas supply pressure configurations available for New York City requirements
  • Input is based on fuel Btu content and altitude of 2,000 feet or less
  • If altitude >2,000 feet and <8,000 feet, derate capacity 4% per 1,000 feet over 2,000
  • Consult factory for higher altitudes
  • Gas input is based on natural gas with 1,000 Btu/cu.ft and 0.60 gravity
  • Oil input based on 140,000 Btu/gal.
