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

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

the fan

also

runs

at

low-speed;

in

medium-low burn mode,

the fan

runs

at

medium-speed;

in

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

which generally

is

dealer

installed,

should

contain a shutoff

valve,

a

fuel

filter

and a

vent.

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.
