This drain pan is intended for use when you evaporator coil is installed with an oil furnace. Oil furnaces burn hotter than either natural gas or liquid propane furnaces. Typically the standard plastic drain pans that come with the Goodman evaporator coils are not made to tolerate this high heat. When installing the high temperature drain pan, the standard plastic drain pan must be removed!
The HTP-B is for use with upflow CAUF and CAPF 17.5" evaporator coils.
