The PP series of gas burners offer a turndown capability up to a 40-1 ratio due to the nozzle mix design and the progressive air mixing of the combustion head. Two heat input rates of 1 million and 2 million BTU/hr per foot length of burner gas manifold provide a greater range of design criteria. The burners can be supplied for operation on natural or LP gases and are available in 12 basic sizes. A variety of air-fuel ratio controls, including full air-gas modulation and gas-only modulation, are available.
