Independence Advantage
• With an annual fuel utilization
of 83.2%, the Independence gives
you excellent value for your
dollar.
• A rear drafthood (Indepen
dence models only) installs in low
overhead areas and allows for
clearance and flexibility for
existingpiping.
•Standard oneach Burnham
Independence Series boiler is a
100% safety shutoff, a time-
proven safety feature with its own
backupsystem.
•A fuel saving vent damper
(Independence models only)
automatically closes the flue to
prevent heat from escaping up the
chimney after the burner shuts off
and reopens it again before the
burner comes on.
•The Independence can also
be equipped with a spark-ignited
electronicignitionwhich
improves energy efficiency.
Burnham's Independence®
Series gas-fired boilers offer you
all the benefits of hydronic heat
withthe advantagesof quality
castironconstructionand
advanced engineering. Offered in
steam or hot water, the
Independence is a quiet, reliable,
and efficient boiler.
The Independence natural draft
boiler is available in ten sizes,
and the power vented steam
model is available in four sizes.
Your contractor can size the
Independence boiler to match the
heating requirements of your
home for optimum efficiency.
Independence PV —
Power Vented Model Available
The Independence PV boiler
offers you all the features of
steam heat with the flexibility of a
power vented boiler. The com-
pletely packaged Independence
PV boiler installs almost any-
where because no chimney is
required for installation.
A draft-inducing fan pulls hot
gases through the heat exchanger
at just the right speed for opti-
mum efficiency. Together, the
heat exchanger and fan provide
more heat with less fuel con-
sumption.Noventdamper is
required.
So, if you don't have a chimney
or if your old chimney is deterio-
rated or not up to code, you can
install the Independence PV boiler
andventdirectlyoutsidethrough
the wall.

The Money Saving Solution
SinceBurnham's Independence
is one of the most efficient boilers
you can buy - with an annual
efficiency of 83.2% - you can
savehundreds ofdollarsduring
yourfirst heatingseason. Com-
pare this to 60% efficiency for a
typical 20 year old boiler or 50%
for a typical 40 year boiler that
may have been converted from
coal firing. Your local Burnham
dealer can test your current unit
and tell you at what efficiency it
isoperating.
For example, say you spend
$1500 on fuel in one year. To
figure out what your annual
savingswouldbe,simplydivide
your existing boiler's efficiency
rating by that of the Indepen-
dence boiler. Multiply that
amount by $1500 and you'll find
outapproximatelyhowmuchit
will cost to operate your new
Independence boiler. You can see
that much of the heat you're
currently paying for is going right
up the chimney!*
Find out how you can enjoy
winter warmth this year, and for
many years to come. Burnham is
the answer to all your heating
needs.
(*Savings will vary based on
yearly heating degree days.)
