it comes to value and innovation, the Criterion II gas furnace offers
you a full range of important features--based on proven designs
and reliable leading edge technology.
Integrated Furnace Control
solid-state integrated furnace control board is the "brains"
of the Criterion II. Using dependable computer technology, it
controls the different components of the furnaces--such as the
blower and inducer motors--to give you a maximum heating capacity
and improved efficiency. The control features low speed continuous
fan operation and accessory terminals. The furnace control also
carries a five-year limited warranty.
Induced Draft Blower
designed this draft-inducing blower to work specifically with
our exclusive heat exchanger. The blower quietly and reliably
pulls hot combustion gases through the exchanger and vents them
safely outdoors when the furnace is in the heating cycle. The
blower is covered by a five-year limited warranty.
hot surface ignitor is an extremely efficient way to ignite the
gas from the burners when the furnace cycles on. With hot surface
ignition, there is no electronic ignition spark and no need for
a standing pilot. During operation, the remote flame sensor constantly
monitors the status of the burner flames.
Gas Valve and Manifold
integrated furnace control signals the furnace to cycle on, it
first waits for the hot surface ignitor to heat up, then it opens
the gas valve. This 24-volt, slow opening valve is a redundant
valve that smoothly delivers gas in a regulated flow to the in-shot
burners for quieter operation.
in-shot burners are carefully matched to the heat exchanger. Their
shutter-free design requires no adjustments to regulate the air/gas
mixture. In fact, they are designed to produce the most efficient
air/gas mixture possible, which means heat is transferred into
your home more efficiently.
heat exchanger is the heat of the Rheem Criterion II Gas Furnace--a
revolutionary design so innovative that is carries three patents.
It's smaller than virtually any other primary heat exchanger on
the market and is constructed of aluminized and stainless steel
to resist corrosion and thermal fatigue. It carries a twenty-year
High Efficiency Blower Unit
high efficiency blower directs warm air filtered through the duct
work to comfortably heat your home. There are no belts or pulleys
that can fail you or wear out.
Easy Access Washable Filter
changing the air filter on your furnace is important because a
dirty filter cuts the efficiency of your furnace and strains its
components. We've solved this problem by making available a permanent
washable filter that is easy to get to and easy to clean.
