The finest
in farge
cast iron
boiler design.
Utilizing a completely
sealed,
forced draft wet base
design, the
Burnhamo
PF-5 Series
requires
no
separate base or
combustion chamber.
The sealed,
forced draftdesign
provides
optimum draft
for controlled combus-
tion, eliminating
the
need for high chim-
neys or mechanical equipment
to artificial$
induce
proper
draft.
The sectional
construction of
the
PF-5 Series
makes it ideal
for
use
in
installations where the
boiler
room is
not
easily
accessible due
to structural
limitations.
In
addition
to being
shipped
as individual
sections the
boiler is available
with
factorv-assem-
bled sections
or as a comptetely
pack-
aged unit.
The
packaged
unit
is
fastened to a steel skid
to facilitate
lift-
ingwith a
fork truck or crane.
The skid
can serve as
the boiler
foundation,
replacing the
need
for
a concrete
pad.
A
factory
fire-test is available on
all
pack-
aged
units.
Available
in eighteen sizes

ing at Gross Outputs

MBH, the
PF-5
Series
frres
gas,

gas/oil
com-
bination
and can be
equipped with
either steam
or water
trim and controls.
The
product
is energy
efficient
with a combustion
efflciency of up
to
82o/o.
All sizes exceed the
efficiency
requirements of
ASHRAE 90.1.

SecuritY
Each
PF-5 boiler section
is
hydrostatically
tested
at
two and
one
half times
ratedworking
pressure
to
make sure
thatthe
section
is
flawless.
Factory-assembled
sections
are tested
at one and
one
half times
the
rated
working
pressure.
The sections
are
surface
ground
to
insure
smooth
surface mating,
and sealed
gas-tight
with an elastic
sealing compound.
This
sealant
is
used
on
all section
joints
to
guarantee
a completely
sealed and
gas-
tight assembly
required
for forced draft
operation.
The sealant
is easily applied
and takes
less time than
applying
conventional
gasket
materials
and
lasts
many
times
longer.
Each section is then
joined
with
quality
cast
iron nipples which will
increase
the
longevity
of the
boiler by
resisting
petroleum
based
chemicals,
including
antifreeze
which can deteriorate the
gaskets
used
in
some competitor's boilers.
Time-
proven
cast iron nipples last the
life
of
the boiler. They expand and contract
along with
the
sections
they
join
ensuring the integrity of the entire sec-
tion assembly.
Thermal
Pump-
Making
Waves
Incorporated
into the
wet base
desrgn
is a
"thermal
pump"
action
that
greatly improves
circulation
in
both
water
and
steam
versions
of
the
PF-S Series.
This thermal
pumP
insures
good
steam
qualify
as
well as
maximum
tankless
heater capacity.
The thermal
pumping action
is
created
by caming
greater heat transfer
on one
side
of the
boiler
than on
the
other.
An upward
flow of
water
occurs
on the
side
where
heat
transfer
is
greatest,
and
a downward
water
flow
results on
the side
where
heat
transfer
is lowest.
Continuous
water
circulation
is assured.

are achieved

Burnham
has earned a
reputation
for
quality
and dependabiliry
going
back to 1856.
To ensure
quality
and
availability,
castings
for the
PF-5
and
all other boilers
are
produced
at
its in-
