(i.e. chimney, vent connector) are clear and free of obstruction.
b.The vent connector is in place, slopes upward and is physically sound without holes or excessive corrosion.
c.The return air duct connection(s) is physically sound, is sealed to the furnace and terminates outside the space containing the furnace.
d.The physical support of the furnace should be sound without sagging, cracks, gaps, etc., around the base so as to provide a seal between the support and the base.
e.There are no obvious signs of deterioration of the furnace.
f.The burner flames are in good adjustment without erratic flames. See illustration below.
