Suitable for firetube, watertube, firebox and cast iron boilers, the standard V series offers natural gas, propane gas, pressure atomized #2 oil and combination gas/oil fuel options from 1.3 to 16.8 MMBTU. The low NOx V series offers natural gas, propane gas, pressure atomized #2 oil, and combination gas/oil fuel options from 1.3 to 14.7 MMBTU. Using advanced technology, the V series offers high turndown on natural gas and low emission capability. The forced-draft design provides clean and efficient combustion. Design features also include a top- or rear-mount panel option, Induced FGR (Flue Gas Recirculation), an FGR modulating valve, and No. 2 oil capability for backup fuel.


Improve Boiler Performance by Replacing the Burner →

In this webinar, attendees will learn the benefits of upgrading their boiler with a new state-of-the-art burner to improve boiler efficiency and better match facility needs.

Parallel Positioning and O2 Trim →

Parallel positioning controls help a burner to optimize its fuel-to-air ratio by using dedicated motorized actuators for the fuel and air valves.
