V/LNV – Series
Suitable for firetube, watertube and cost iron boilers; the V series features a unique aerodynamic air damper design which permits accurate air-to-fuel settings for maximum combustion efficiency. The standard V series offers natural gas, propane gas, pressure atomized #2 oil and combination gas/oil fuel options at capacities from 1,300,000 to 16,800,000 Btu/hour. The low NOx V series offers natural gas, propane gas, pressure atomized #2 oil, and combination gas/oil fuel options at capacities from 1,300,000 to 14,700,000 Btu/hour. Through the use of advanced technology, the V series offers high turndown up to 10:1 on natural gas, and low emission capabilities with turndown up to 5:1.
Features Include:
- Natural gas, propane gas, pressure atomized #2 oil and combination gas/oil fuel options
- Cam trim with 14-point adjustment range for consistent air/fuel ratios
- Parallel positioning available for optimal control throughout the firing range
- Up to 10:1 turndown on natural gas and optional low NOx with up to 5:1 turndown
- Unique aerodynamic air damper design for optimal flow control
- Forced draft for clean and efficient combustion
- Top or rear mount panel options
- Induced FGR
- FGR modulating valve
- FGR shutoff valve
- Cam trim with 14-point adjustment range on FGR

Notes (V-Series):
- Motor ratings for gas only or gas/oil burners using a remote oil pump
- Motor ratings for oil only and gas/oil burners using a direct drive oil pump
- 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
- Low/High and Full Modulation minimum gas pressure
- 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.
