and
instantaneous closing
magnetic
solenoid valve
for smooth,
clean
starts and
sharp, clean cut-offs.
COMBUSTION HEAD and ELECTRODE ASSEMBLY
—
Unique
CRD
"controlled flame retention"
design provides adjustable
aerodynamics
so that air pattern and
velocities
can be op¬
timized for
any
nozzle size within the entire
range of
the
burner without
a
change of parts.
High-chromium stainless steel electrodes with porcelain
insulators fully
glazed and
counterbored
for
maximum clean-
ability and safety. Stainless steel heat shield
on
air tube pre¬
vents
overheating of combustion head and nozzle.

TYPICAL FLANGE APPLICATIONS
EFFECT OF BACK PRESSURE ON MAXIMUM FIRING RATES
The maximum firing
rates
of
5.00
gph
for Model 200CRD
and 5.50 gph
for Model 201CRD
are based on operation with
zero to
slightly
negative
pressure such as 0.01"
to
0.03" W.C.
draft
over the fire as normally encountered
in
a
natural draft unit.
When
a
unit is designed for forced draft operation with a positive pressure
(back pressure)
over the fire, the maximum air capacity
of
the burner is reduced in proportion
to
the
amount
of pressure. As
a
result, the maximum firing
rate
is also reduced. The graph,
right,
shows the
maximum
firing
rate
in gph of each
model with
various
amounts
of pressure in the
combustion
chamber.
As an example, the
Model 200CRD
has a
maximum
firing
rate
of
just over 4 00 gph when
fired against a back
pressure
of 0.20" W.C.
Note: Installation
of
Models 200CRD and 201CRD in trailers or
furnaces
with more than
0.1"
back pressure or with undersized breechlngs (See Table
A)
or chimneys
(See
Table
B)
Is
not recommended
unless
the unit has been pre-tested with these burners under these
conditions.
