| General Description |
| The D-Series HEV-E-DUTY gas, oil, and combination gas/oil burner is a forced draft packaged burner system. A backward curved cast aluminum impeller mounted in a machinded housing provides vombustion air for various furnace pressures or high altitude applications. The air housing is hinged for convenient inspection or service of the firing head components. |
Type of fuel determines the model designation. |

| Oil firing features I.C.'s low pressure air atomizing design. A positive displacement oil metering unit, rotary vane air compressor, and air atomizing nozzle are intergral parts of this system. The positive displacement oil metering unit is not affected by changes in oil temperature or viscosity. |

| High turndown capability on all fuels assures smooth starts and response to wide load demands. Maximum efficiency is achieved throughout the firing range. Convenient control switches permit selection of fixed rate or fully modulating operation. Combination gas/oil burners change from one fuel to the other by simply flipping a switch. No burner modifications or readjustment are required when changing from one fuel to the ohter. |
