are
composed
of the
following:
a
spill
tray, a cabinet, a combustion system,
an air
circulation system, a fuel delivery system, electrical
and
electronics systems
and a
variety
of
safety
mechanisms.
1-8
SPILL
TRAY
The
Spill
Tray:
—
Protects
the
floor from damage resulting from
fuel
spillage.
—
Provides a secure,
tip-resistant
heater base.
Metal retainers
(2)
secure
the
heater
to the
Spill
Tray.
The
legs
are
positioned with
in the
circular indenta-
tions.
1-9
HEATER CABINET
A
steel
cabinet
holds
and
protects
all
internal
com-
ponents.
A
number
of
primary parts
are
assembled
to
form
this
housing.
1-10 CMBUSTION SYSTEM
The
Combustion System
is
responsible
for the
pro-
duction
of
heat which
is
circulated into
the
room
.
In the
Combustion Systems a mixture
of
fuel
and air
is
burned
to
produce
heat.
Air is
drawn from outside
the
dwelling
into
the
Combustion
Chamber.
At the
same
time, fuel
is
metered
from a storage cavity into
this same Combustion Chamber.
Within
the
cham-
ber,
the
air/fuel mixture
is
ignited
to
produce heat.
The
Monitor combustion systems
are
safeguarded
by a pair
of
overheat protector switches; They
will
shut down
the
heater
(to
protect
it
from damage)
in
the
event
of
excessive heat
build-up.
The
overheat
protector
switches reset automatically after
cooling
down.
1-11 COMBUSTION CHAMBER
This
tall
cylinder
is
positioned
on the
Heater Base.
It
is
secured
to the
base
by
phillips
head screws.
Connected
to the
Combustion Chamber
are the ig-
niter, (located within
the
chamber) a fuel
line,
the
Heat
Exchanger,
and a
Flame Sensor.
Within
the
Combustion Chamber
are the
Burner Pot,
the
Combustion Ring Assembly. Access
to
those
in-
ternally-located parts
is
facilitated
by a
removable
Service
panel.
A
Window
on the
panel
lets
the
technician
visually
examine
the
combustion
process(i.e.
glowing igniter
or
proper flame color).
An
airway,
in the
Cabinet Base, extends from
the in-
take
fan of the
Combustion Blower
to the
hollow
base
of the
Combustion Chamber.
This
airway chan-
nels
air to the
Combustion Chamber.
The
Flame Sensor
is
mounted with
two (2)
phillips
head screws onto
the
wall
of the
Combustion
Cham-
ber.
1-12
BURNER
POT
Designed specifically
to
support combustion,
the
Burner
Pot
(refer
to
Figure
1-2/1-3)
contains a series
of
air
holes,
an
igniter tube
(to
accommodate
the Ig-
niter),
and a
fuel
inlet
fitting
(interconnects
the
fuel
line).
It
is
secured
to a
mounting plate near
the
bot-
tom
of the
Combustion Chamber.
The
Combustion Ring Assembly
is
seated
on
three
(3)
screws
or
pins
in the
Burner Pot.
1-13 COMBUSTION RING
ASSEMBLY
This assembly
is a
special structure, designed
to
promote efficient combustion.
1-14 FLAME
SENSOR
Mounted
on the
outside wall
of
Combustion Cham-
ber,
the
Flame Sensor always supervises
the
flame.
1-15 IGNITER
Located within
the
igniter tube
of the
Burner Pot,
the
Igniter
is
designed
to
pre-heat
the
Burner
Pot and to
vaporize
and
ignite
the
air/fuel mixture
to
start
the
combustion process.
The
Igniter
is
secured
by a
bracket
and
screw
to the
igniter tube.
The
cover plate
is
secured
to the
com-
bustion chamber
by
three
(3)
phillips
head screws.
1-16 COMBUSTION
AIR
SYSTEM
The
Combustion
Air
System channels
air to and
from
the
heater.
Outside
air is
drawn into
the
heater
by the
Combus-
tion
Blower through
an
airway
to the
Combustion
Chamber.
A
Combustion Blower draws
the
intake
air in
through a Flue Pipe. This
air
enters
the
Combustion
Chamber
at the
Burner
Pot and
mixes with
the
fuel
to
support
combustion,
Remaining
air is
heated
and
is
drawn
into
the
Heat Exchanger.
As
the
heated
air
passes through
the
Heat Exchan-
ger,
an Air
Circulation
Fan
blows room
air
past
the
Heat
Exchanger
and out
again into
the
room, heating
passing
air by
convection. Exhaust vapors
exiting
from
the
Heat Exchanger
are
vented through
the
Flue
Pipe.
A
deterioration
of air
pressure
at the Air
Pressure
Switch
is an
abnormal condition;
the
heater
is
shut
down
by the
malfunction.

Assembly con-
sists
of two
concentric tubes. Outside
air is
drawn
through
the
cylindrical space between
the
tubes.
Combustion by-products
are
vented through
the in-
ner
tube.
As
the
cool
air
enters,
it is
heated
by the hot air
that
is
exiting
the
system.
A
large-bore,
flexible
hose connects
the air

HEAT
EXCHANGER
An
inlet
at the top of the
Heat Exchanger permits
the
heated
air to
travel from
the
Combustion Chamber
into
the
exchanger.
An
outlet,
at the
bottom
of the
exchanger, permits
combustion by-products
to be
vented
to the
Flue
Pipe.
air
within
the
exchanger heats
the
outside metal
walls.
The hot
metal walls,
in
turn, heat
air
that
is
pushed
past
the
exchanger
and is
circulated into
the
room.
An air
baffle, directly
in
front
of the
exchanger,
deflects
the
heated
air
upwards,
and
out, through
the
louver
assembly.
A
pair
of
Over-Heat Protector Switches protect
the
heater
from
damage
due to
excessive heat built-up.
1-20
AIR
CIRCULATION
FAN
Circulation fans
are
driven
by
three-speed motors
and are
designed
to
circulate
the
heated room air.
If
the
heater
is
running
in low
burn modes,
the fan
also
runs
at
low-speed;
in
medium-low burn mode,
the fan
runs
at
medium-speed;
in
medium-high
or
high burn modes,
the fan
advances
to
high speed.
Operation
of the fan is
controlled
by the
micropro-
cessor
and fan
thermostat switch.
Physically assembled with a protective wire cage
for
the
heater,
the
entire
fan
assembly
is
secured
to a
bracket
on the
rear
of the
Heater Cabinet.
A
metal conduit,
at the
rear
of the
heater, protects
the
fan
wiring from damage.
1-21
AIR
PRESSURE
SWITCH
This
switch consists
of a
rubber diaphragm which
senses
changes
in air
pressure(it
is
connected
to the
Combustion Blower)
and is a
normally open, micro
switch.
Should
an
abnormal pressure differential exist,
the
switch opens
to
disable
the
circuitry that controls
the
supply
of
fuel.
Since
the
flow
of
fuel
to the
Burner
Pot
is cut
off,
the

contain a shutoff
valve,
a
fuel
filter
and a

Installation
of the
tank should
conform
to
local
regulations
and to the
specifica-
tions
and
guidelines
documented
in
this
Service
Manual.
1-24 FUSIBLE LINK
VALVE
Basically,
the
Fusible Link Valve
is a
safety mecha-
nism that
cuts-off
fuel
to the
heater
in the
event
of
an
overheat
condition
at the
valve.
In
M-2400/M-2200,
Fusible
Link
Valve
is not
instal-
led,
If
necessary,
it can be
installed
outside
of the
appliance.
The
Fusible Link Valve
is a
springloaded
device that
cuts
off the
supply
of
fuel
to the
heater when
the
temperature level
(at the
valve)
exceeds a predefined maximum
limit.
An
inlet
on the
bottom
of the
valve
allows
fuel
to
pass
into
the
heater.
The
handle-which
can
also
manually
be
opened
or
closed-sits
on a
springloaded stem which contains a low-melting point
alloy.
Fuel
enters
the
Fuel Constant
Level
Valve
through
an
inlet
at the
bottom
of the
reservoir.
As the
level
of
fuel rises,
it
passes through a filter (which
removes
most
particles
and
foreign matter
from
the
fuel),
flows
up
through
an
open inlet valve
and
enters
the
tank.
IMPORTANT:
The
Fuel
Constant
Level
Valve
filter
should
be
cleaned
or
replaced peri-
odically.
Time
intervals
will depend
on
purity
and
quality
of
fuel.
Within
the
Valve, a float mechanism controls
the
level
of
fuel that will
be
permitted
to the
reservoir.
As
the
fuel level drops,
the
float drops down
to
increase
the
inlet
valve opening
to
admit
more
fuel
into
the
valve.
When
the
fuel level reaches
its
maximum
volume,
the
float
rises
to
shut
the
inlet valve.
In the
event
that
fuel
within
the
reservoir
rises
to an
abnormally high level, a float within
the
reservoir
rises
to
trip a safety magnet. This safety magnet
locks
out the
float
to
prevent fuel from entering
in the
reservoir.
Should a foreign substance cause
the
inlet
valve
to
stick
(or
prevent
it
from opening),
the
Fuel
Set
Lever
is
utilized
to
free
the
valve
and to
admit fuel
to the
reservoir.
A
CAUTION:
Care
must
be
taken
to
prevent
dust,
dirt,
or
other debris from
clogging
or
blocking
the
inlet
valve.
If
debris collects
on the
seat
of the
inlet
valve
it may
cause
tripping
of the
safety
lever
and
will
require cleaning.
1-25
FUEL
CONSTANT
LEVEL
VALVE
This valve
has an
automatic shutoff safety mecha-
nism
and a
Fuel
Set
Lever.
The
safety mechanism
prevents
fuel from flooding
or
overflowing
from
the
fuel
reservoir.
The
Fuel
Set
Lever resets
the
float
so
the
Fuel Constant Level Valve
can
resume opera-
tion.
The
fuel reservoir
is a
tank which contains a float
assembly, a safety mechanism,
and a
priming lever.

can
be
performed
quickly
and
economically.
The
Monitor
2400/2200 model
is
strictly a remotely
fueled
system
and is
externally vented.
As
such
it
needs
the
installation
of an
externally vented
intake/
exhaust
system
and if
remotely
fueled,
will
need
the
installation
of a
remote fuel storage tank.
By
completing each step
of the
easy-to-follow
installation
instructions
(each step should
be
com-
pleted
in the
exact order
specified),
the

Remove
all
combustibles
from
the
heat-
ing
area.
Unless
building
or
fire codes
dictate
otherwise,
the
Monitor system
can be
placed
on any
floor surface
(including
carpeting
or
other combustible material)
and
provide safe
operation.

Installing
an
Extension

requires
the
construction
of
an air
line
and the
exhaust
line.
The air
line
is
connected between
the Air
Supply Elbow
at the
rear
of
the
heater
and the air
inlet port
on the
Flue
Pipe.
Similarly,
the
exhaust
line
is
connected
between
the
joint pipe
at the
rear
of the
heater,
and the
exhaust
port
on the
Flue Pipe.
IMPORTANT:
The PVC air
line
is
longer
than
the

line
and may
need
to be cut
to
size.

to
indi-
cate
that-
power
has
been
applied
to the
instrument
and the
heater
is
cycled
for
manual mode
of
opera-
tion.
INSTRUCTIONS
FOR
ECONOMY PLUS MODE
To
engage
the
economy
plus
mode,
simply
press
down
the
button
labeled
"Economy
Plus",
to
disen-
gage
press again.
NOTE:
Operation switch must
be
"ON"
and in
MAN-
UAL
mode.
This feature minimizes
the
"ON"
and
"OFF" cycling
of
the
unit
by
allowing
it to
overshoot
the set
tempera-
ture
by 8
degrees instead
of the
normal 4 degrees.
The
advantages
of
this feature
are to
increase
the
overall efficiency
of the
unit
by:
1.
Decreasing
electrical
consumption
by
decreasing
the
frequency
of
ignition
cycles.
2.
Reducing heat loss during
the
prepurge
and
post-
purge
cycles.
3.
Reducing inefficient combustion associated with
start
up and
shut down.
4.
Prolonging component life
by
decreasing expan-
sion
and
contraction
of
internal parts.
NOTE:
This feature could
be
compared
to
driving
an
automobile
in
stop
and go
traffic
(regular
mode) versus highway
driving
with cruise
control engaged (Economy Plus mode).

to
diagnose,
even
though
it
will adversely affect heater operation

fuel contamination
is
suspected
is to
examine
all of the
system's fuel filters, beginning
with
the

nozzle should also
be
cleaned. This
can be
done
as
follows:
1.
Disconnect copper fuel

2.
Push a piece
of
wire (about
the
same size
as the

of

the
fuel inlet nozzle.
3. If

twist wire back
and
forth
(to
brake

so
that wire ultimately
penetrates
