MNG Nozzle-Mix gas burners operate with a wider stability range than premix burners. Ease of installation, operation, and maintenance has been stressed in the MNG design. This burner in lower capacities like 4000 or 7000 kCal/hr is being mostly used as an integrated pilot for higher capacity burners while it has high flame retention and easy to be tuned. The wide stability range makes the MNG ideal for multiple burner applications. The MNG flame is visible from an observation port installation on an air inlet. Although the length of the flame can not be judged fully, it is still useful to use the observation port for setting up the burner and monitoring performance installation.
Since MNG flame starts from internal housing of it, it needs internal igniter.
