IMPORTANT:
Models
200CRD
and
201CRD
are
identical
in
all
respects
except
for
the
diameter
of
the blower wheel
(fan)
which
is
larger
in
Model
201CRD
to
provide
adequate
air
for
the
higher
firing
range.
All
other
parts
are
interchangeable,
a
significant
advantage
in
servicing
and
in
keeping
parts
in¬
ventories
to
the
lowest
possible
level.

Carlin
"CRD"
oil
burners
feature
an
adjustable
com¬
bustion head
assembly
which
permits
regulation
of
the
air
pattern
in
the
flame front
area
for
optimum
velocity
with
symmetrical
distribution
whether
the
firing
rate
be
at
the
low,
intermediate,
or
high
portion
of
the
firing
range.
The
usual
lack
of
turbulence
at
the
lower
firing
range
in
other
burners
has
been
overcome
and the
adjustment
feature
"tunes
out" instabilities
and
rough
starts
inherent
in
fixed-head
designs.
Significant
advantages
offered
by
"CRD"
burners
include:
•
Smooth
operation,
relatively
low
noise level.
•
Clean
combustion;
zero
to
trace
of
smoke.
•
Instantaneous
cut-off
assured
by
solenoid
oil
valve.
•
Higher
CO?
for
optimum
efficiency.
•
Excellent
performance
in
tested units
without
a
refractory
combustion
chamber.
•
Positive
ignition
and
stable
operation.
•
Flame is
narrow
and
compact.
•
Insensitive
to
draft
or
back
pressure.
•
Can
operate
as
a
forced draft
burner.
•
Highly
resistant
to
pulsation.
•
Same
air
handling
parts
over
entire
firing
range
of
each
burner.
•
Compact
design
using
standard
components.
•
Easy
to
install,
adjust,
and
service.
