NX Oil Burner

The NX uses standard components, combines air and head settings into one adjustment and allows the zero position to be set without removing the burner. Patented air guide and scroll insert deliver high static pressure to provide clean combustion in modern appliances, even in tough situations. The standard sound cover and high-quality components provide quiet operation. High static pressure and the air intake kit are ideal for direct venting.
