Read our privacy policyThe LPM-33 liquid propane (LP) conversion kit is used to convert the fuel type used by Goodman's GR9S92, GR9S96, and GD9S96 furnaces and their single stage GPGM3 gas packaged units from natural gas to propane. Goodman furnaces and gas packaged units are made to operate on natural gas by default. A propane conversion kit is required for any Goodman furnace or gas packaged unit installation where it needs to run on propane instead.
This conversion kit is made to work with Goodman's regular and low NOx GR9S92, GR9S96, and GD9S96 furnaces as well as their single stage GPGM3 gas packaged units. Please note that it cannot be used with ultra-low NOx variations of those furnaces, the ultra low-NOx GPUM3 gas packaged unit series, and the two-stage GPGM3 models (GPGM36008031, GPGM36010031, and GPGM36012031). If you are looking for the propane conversion kit for the two-stage GPGM3 packaged units, please see model LPM-34.
