BURNHAM INDEPENDENCE SERIES
GAS-FIRED STEAM OR HOT WATER BOILER
Long Term Home
Comfort and Quality
Burnham's Independence
Series gas-fired boilers offer you
all the benefits of hydronic heat
with the advantages of quality
cast iron construction and
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 completely packaged Independence
PV boiler installs almost anywhere because no chimney is
required for installation.
A draft-inducing fan pulls hot
gases through the heat exchanger
at just the right speed for optimum efficiency. Together, the
heat exchanger and fan provide
more heat with less fuel consumption. No vent damper is
required.
So, if you don't have a chimney
or if your old chimney is deteriorated or not up to code, you can
install the Independence PV boiler
and vent directly outside through
the wall.
®
Quality Construction
Made in the USA
Every Burnham boiler is made
in the U.S.A.
All Burnham
heat exchanger
castings are
produced
“in-house”
to ensure
quality and availability. Burnham
is the only boiler manufacturer
that can make that claim.
Rugged cast iron sections
Hundreds of heat extracting
pins extract the maximum amount
of heat, reducing fuel consumption and saving you money.
Steel couplings called nipples
Steel nipples increase the
longevity of the boiler by
resisting petroleum based
chemicals, including antifreeze.
These inhibitors can deteriorate
the rubber type gaskets which
are commonly found in some
competitors' boilers.
Lifetime True-Blue
limited warranty
Burnham stands behind every
Independence boiler with a 10year limited warranty on the
steam heat exchanger, and a
lifetime limited warranty on the
water heat exchanger. The
additional purchase of Burnham’s
Winter Warmth Assurance plan
extends the True Blue Warranty
protection of the heat exchanger
to 5 or 10-year blanket coverage.
The program pays 100% for parts
and labor on qualified repairs for
5 or 10 years from the date of
installation. See your Burnham
Home Heating Team contractor for
more information
Independence Advantages
• 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
existing piping.
• Standard on each Burnham
Independence Series boiler is a
100% safety shutoff, a timeproven safety feature with its own
backup system.
• 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
electronic ignition which
improves energy efficiency.
Burnham Nipple vs. Competitors' Gasket
2
• Burnham uses quality
Honeywell controls on the
Independence and the
Independence PV.
• Industrial quality pressuretrol
for accurate, trouble-free control.
• Stainless steel burners equal
long life with no rusting like
aluminized burners.
• Step-opening gas valve
enablesthe boiler to start on low
fire and continue on to high fire
safely and smoothly providing
quiet ignition and long life. The
valve is concealed inside the
boiler jacket, hidden from
children and safe from accidental
bumps and tampering.
• Power vented model simplifies
installations when a chimney isn't
available.

The Money Saving Solution
Since Burnham's Independence
is one of the most efficient boilers
you can buy - with an annual
efficiency of 83.2% - you can
save hundreds of dollars during
your first heating season. Com-
C
D
E
F
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
is operating.
For example, say you spend
$1500 on fuel in one year. To
figure out what your annual
savings would be, simply divide
your existing boiler's efficiency
rating by that of the Independence boiler. Multiply that
amount by $1500 and you'll find
out approximately how much it
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!*

1. Ratings shown are for installations at sea level and elevations up to 2,000 ft. For elevations above 2,000 ft., ratings should be
reduced at the rate of four percent (4%) for each 1,000 ft. above sea level.
2. Capacities, outputs and ratings are based on steam combustion efficiency of 82.5%. Water combustion efficiency is 83.5%.
3. For Canadian builds only: Reduce input and output by 3%.
4. 15 ft. height is measured from top of drafthood to top of chimney.
5. IN6, IN8, & IN10 - Canada only: Increase chimney diameter by 1".

1. Capacities and ratings are based on steam combustion efficiency of 83.0%. (84.1% for PIN3PV)
2. The approved venting system for the Independence PV is 3" AL29-4C® stainless steel. Do not substitute other materials.
3. Vent pipe length is listed in equivalent feet. Any elbows or tees used have specific values which must be subtracted from the
total length to determine maximum length of straight pipe. Consult Installation, Operating and Service Instructions for details.
