INTRODUCTION
The National Applicance Energy
Conservation Act (NAECA) of 1987
states that any gas furnace
manufactured after January 1 , 1992,
must have a minimum Annual Fuel
Utilization Efficiency (AFUE) of 78%.
The higher the AFUE percentage the
more usable heat energy the
consumer gets for every dollar of fuel
purchased. This is similar to the
EPA's minimum gas mileage
requirement for automobiles. It gives
the consumer a relatively easy way to
make direct efficiency comparisons
between different furnace brands
and styles.
A high AFUE value, which translates
into a low operating cost, is not the
only concern that consumers have.
They also want a furnace with a
reasonable installed cost. They want
a furnace that provides them with
comfort - their main concern. And
they expect a furnace with
exceptional reliability and longevity.
Gas furnace manufacturers are
always striving to provide consumers
with the best furnace value. The Low
Profile Furnace addresses all those
consumer needs. It gives exceptional
efficiency with a low installation cost.
It delivers the comfort the customer
wants along with the reliability they
expect.
The key to all these customer
benefits is the furnace's heat
exchanger. Its unique design delivers
up to 82.2% efficiency with consistent
warm air delivery for comfort. The
materials used to construct the
furnace in general and the heat
exchanger in particular make it a
rugged, long lasting unit. The unique
heat exchanger design provides the
customer with a furnace only 34
inches high. This gives the consumer
a unit easily installed in almost every
location that accepts all customary
accessories.
With the introduction of higher
efficiency furnaces, special attention
must be paid to the venting system.
Only listed venting systems may be
used as stated in the installation
instructions and the
National Fuel
Gas Code, ANSI Z223. 1 (NFPA 54),
or the Canadian CANICGA B 149. 1
and B149.2 lnstallaton Codes for Gas
Burning Appliances.
Since furnace
technology and venting requirements
are changing, awareness of local,
state, and federal codes and industry
changes is imperative.
IMPORTANT: PROPER APPLICA-
TION, INSTALLATION AND MAIN-
TENANCE OF THIS FURNACE IS A
MUST IF CONSUMERS ARE TO
RECEIVE THE FULL BENEFITS
FOR WHICH THEY HAVE PAID.
