Honeywell VR8205M 2443 and 3 burner orifice. Differences from a Nordyne G5R TO A G6R model furnace? I am looking to convert to LP (propane) and want to be sure I order the correct parts. Allot of information on the G6, nothing on G5. Canadian model? I am very remote, there will be no service tech. Need to know the orifice size and header pressure drill 54 and 10-13 WC I think but it would be nice to see it in writing.
