Nationwide Boiler Inc., a pioneer in innovative boiler solutions, is thrilled to announce the successful completion of third-party testing, confirming ultra-low NOx performance below 2.5 ppm for their pre-stocked 350 horsepower firetube boiler package. Conducted at the Superior Boiler factory in Hutchinson, Kansas, by Montrose Air Quality Services—a renowned authority in emissions testing—the comprehensive test demonstrated NOx emissions consistently under 2.5 ppm, corrected to 3% O2, across the entire operational range from low to full capacity. This breakthrough not only solidifies Nationwide Boiler’s position as a leader in environmentally friendly technologies but also exemplifies the company’s unwavering commitment to sustainability.
Nationwide Boiler’s Vice President of Sales, Jim Lieskovan, expressed pride in this milestone, stating, “This accomplishment reflects our strategic collaboration with Superior Boiler and Oilon, a global innovator in burner and heat pump technology. Our shared vision of environmental responsibility has yielded an unparalleled product that surpasses industry expectations. We’re proud to deliver yet another reliable and eco-conscious solution to our valued customers.â€
The 350 HP Superior firetube boiler package is already available and features Oilon’s LN30 (ULN2.5) ultra-low NOx burner.

Built entirely by Oilon—one of the world’s leading burner manufacturers—the UL-approved LN30 series boasts an extensive support infrastructure, including Nationwide Boiler’s in-house engineering, service, and R&D teams. Burners, ranging from 70 HP to 450 HP, along with replacement parts, are stocked at Oilon’s Thomasville, Georgia facility, ensuring rapid response to customer needs. Additionally, the Oilon LN30 burner includes a five-year warranty on the burner head and extension, reinforcing its durability and reliability.
