NP burners

NP burners have been specially designed for application in wall-hung boilers and water heaters in categories B and C that run with any type of combustible gas.
In any event, their flexibility of use allows application on special devices or more in general, wherever it is necessary to use a source of heat powered by gas (for example, coffee roaster, etc.)

The main operating characteristics guarantee:

  • low emissions in compliance with the current European regulations
  • low noise levels, compliant to the strictest European standards
  • efficiency according to 3-star standard for traditional boilers, both open-chamber and sealed chamber
  • efficiency according to 4-star standard for condensing boilers with recuperator
  • operation without the need to calibrate the gas valves where smart combustion systems are involved
  • function on gases of the first, second and third families by changing the injectors, without any air regulation system

This specific construction system allows for the creation of burners:

  • easily adaptable to any heat exchanger
  • with different widths, varying the number of elements from a minimum of 5 to a maximum of 20
  • with different depths, using burner bodies L=157mm or L=140mm

The NP burner is compatible with:

  • electronic ignition systems, either mono or multiple electrode, that may be positioned either on the plate or on the spacer
  • ignition system with pilot, that may be positioned either on the plate or on the spacer

NP burners are always equipped with a gas manifold, which may be:

  • assembled directly on the burner
  • provided as an accessory

The gas manifold is set up for:

  • connection to the gas valve with male or female connections, ½” Gas or ¾”Gas thread or quick connections
  • brackets for positioning the burner in the boiler
