Allied Air 68w77 Natural to Lp Gas Conversion Kit

Product Description

The ALLIED AIR 68w77 is a natural gas to liquid propane (LP) conversion kit designed for the A97USM 97% AFUE modulating gas furnace. This kit supplies the components needed to reconfigure the furnace gas valve and orifice system from natural gas operation to LP operation. It is installed by a licensed HVAC technician as part of a planned fuel-source changeover, typically when a unit is being placed in service at a location without access to a natural gas utility. The kit ships at approximately 1 pound, making it a compact, single-use service part.

This conversion kit applies specifically to the Allied Air A97USM series 97% modulating gas furnace. It is appropriate for residential installations where the fuel source is liquid propane rather than natural gas. Technicians performing a natural-to-LP conversion must complete the full conversion procedure per the furnace manufacturer's installation instructions, including adjustment of gas valve settings, replacement of burner orifices, and proper labeling of the converted unit.
