80MGF Series


Units are factory equipped for use with natural gas. A kit is available for conversion to LPG operation. All 80MGF units built prior to September 98 use electronic (direct spark) ignition. 80MGF−11 model units are equipped with the LennoxSureLight ignition system. 

The 80MGFX unit meets the California Nitrogen Oxides (NOx) Standards and California Seasonal Efficiency requirements. All units use a redundant gas valve to assure safety shut−off as required by A.G.A. or C.G.A.

The heat exchanger, burners and manifold assembly can easily be removed for inspection and service by simply disconnecting gas, unplugging wiring harness and spark wires and removing four screws holding the heat exchanger in place. Then the heat exchanger slides out of the cabinet.

Units may be installed in upflow, downflow or horizontal position. The heat exchanger is designed for upright or horizontal use only. When the unit is installed in the downflow position, the heat exchanger is field removed and reinstalled so it is upright when the cabinet is inverted. No field conversion is required when the unit is installed in the horizontal position.
