2013 Granby KHM-100 Oil furnace with riello 40 burner. Capable of between 77,000btu/h and 105,000btu/h. Currently set up for 105,000btu/h.
We are the second owners, currently set up with return air at the back, has previously used knockout on the left hand side covered, but easily changed by a qualified installer. Great little furnace, just moved to electric instead of replacing the tank for better or worse.
Comes with 5" hoyme powered damper for the combustion air, and a 5" combustion air 'can' (used instead of automatic damper if you or your installer prefers not to use the powered damper)
