2-Stage OH6 Oil Furnace
Dependable Craftsmanship
with Maximum Comfort
Your home is your castle – that’s how the saying goes. So,
when you’re looking for a new oil furnace look no further
than the ermo Pride 2-Stage OH6 oil furnace. is state-
of-the-art furnace will provide your family with luxurious
comfort and energy savings for many years to come.
e 2-Stage OH6 combines the benefits of the time-tested
and proven low-profile highboy OH6 oil furnace coupled
with a 2-Stage Riello oil burner and an electronically com-
mutated blower motor (ECM.) e 2-Stage burner operates
at a standard low fire rate most days comfortably heating
your home and saving energy. On those bitter cold days
when your home needs the extra heat, the burner automati-
cally switches to high fire providing additional warmth. e
ECM motor gives you even more comfort by operating with
infinite blower speeds that automatically adjust for varying
heating and cooling modes. When heat is needed the blower
smoothly ramps up to speed gently circulating the warm
air around your home and eliminating that annoying blast
of cold air from your registers. All you feel is comfort. e
ECM motor’s infinite speeds also increase your furnace effi-
ciency while the motor pays for itself with dramatic electrical
savings in both the heating and cooling modes.
e 2-Stage OH6 combines all the features you would
expect from ermo Pride’s tradition of handcrafted quality
with new high-tech design.
It is backed by ermo Pride’s
Peace of Mind lifetime
limited warranty - virtually
eliminating the worry of ever having to replace your furnace
again. Should you sell your home, the warranty will auto-
matically transfer to the new homeowners.
is is the furnace you deserve – the 2-stage OH6. Today’s
state-of-the-art technology combined with ermo Pride’s
traditional hand crafted quality.

2-Stage Burner Easy Setup
e 2-Stage burner is easy to set up and service. Your
contractor merely moves a pin and adjusts it for
low fire as with a traditional burner, then moves the
pin again and sets it up for high fire. Lastly, he will
move the pin to the third setting to run. e burner
will then switch from low to high fire automatically
as needed. e burner is also mounted on a double
hinge making it easy to service as needed.
