A local church is heated by the following:
Lennox Oil Fyre Furnace, unit number CB5-27M with an Adams Speed Flame Model HP400BPS S/N DSA-11835 gas conversion burner.
And a Lennox Oil Furnace # OF4-175M S/N 986553 with an Adams Speed Flame # IIP-400BBS S/N 17705 gas conversion burner.
Any idea how old these things are? How efficient? More like how inefficient.
