FP – Series
Suitable for cast iron, firebox and scotch marine boilers; the FP series burners are effective where high heat release is required or where a restricted combustion chamber exists. The FP series offers natural gas, propane gas, pressure atomized #2 oil and combination gas/oil fuel options at capacities from 550,000 to 4,200,000 Mbtu/hour.
Features Include:
- Gas, light oil and combination gas/oil fuels
- Gas/electric ignition on gas and combination gas/oil units
- Direct spark ignition on oil units
- Upright model option for low boiler base heights
- Honeywell and Fireye control options
- Remote oil pump optional
- Pressure atomized
- On/Off standard on models 5-7
- Low-High-Low/Off standard on models 8-25
- Full modulation standard on models 28-42
- UL & cUL listed

Notes:
- Firing rates based on 60 cycle and an altitude up to 2,000 ft. above sea level.
* For blower wheel and motor sizes at higher altitudes, and 50 cycle applications, consult factory. - Oil input based on No. 2 oil @ 140,000 Mbtu/gal
- Gas input based on Natural Gas @ 1,000 Mbtu/cu.ft. and 0.60 specific gravity
- Lower furnace pressures may reduce motor HP requirements
- Boiler overall efficiency of 80% estimated
