1. Net ratings are based on a piping and pick-up allowance of 1.15. Consult manufacturer for installations having unusual piping and pick-up requirements,
such as intermittent system operation, extensive piping systems, etc. Ratings are for installation from sea level to 2000 feet elevation.
2. Firing rate in GPH is based on oil having a heat value of 140,000 BTU/GAL.
3. Tankless heater ratings are based on continuous draw (GAL./MIN) at 40°-140°F rise with 200°F boiler water temperature.
Note: All sizes meet or exceed 80% combustion efficiency.

RATINGS - TANKLESS COILS*
*Based on 100°F rise with 200°F boiler water temperature
and 40°F heater inlet temperature (continuous draw).
For use of the FD Series as a continuous hot water supply
boiler, select the boiler and tankless coil based on the required
amount of hot water flow. Heating needs should be consid-
ered in addition to hot water requirements. If control of hot
water temperature and flow is desired, temperature and flow
controls may be added.
Contact Burnham Commercial for inlet temperatures in excess
of 70°F, or if a temperature rise other than 100°F is desired. If
pressure drops are found to be excessive, it is possible in some
cases to oversize the heater.
