The York G8C Multi Position gas furnace is a (discontinued) furnace that has been replaced by the GG8S and TG8S model groups. The G8C has an acceptable AFUE rating of eighty percent. The government minimum standard AFUE is seventy-eight percent.
The G8C is short, which makes it ideal for installation in small spaces. It can be converted to propane and can also be vented with other gas appliances.
