used

in

conjunction

with

air

conditioning,

the

furnace

shall

be

installed

in

parallel

with

or

upstream

from

the

evaporator

coil

to

avoid

condensation

in

the

heat

exchanger.

In

a

parallel

installation,

the

dampers

or

air

controlling

means

must

prevent

chilled

air

from

entering

the

furnace.

If

the

dampers

are

manually

operated,

there

must

be

a

means

of

control

to

prevent

the

operation

of

either

system

unless

the

dampers

are

in

the

full

heat

or

full

cool

position.

The

air

heated

by

the

furnace

shall

not

pass

through

a

refrigeration

unit

unless

the

unit

is

specifically

approved

for

such

service.

The

blower

speed

must

be

checked

and

adjusted

to

compensate

for

the

pressure

drop

caused

by

the

evaporator

coil.

Refer

to

Appendix

B

for

recommended

wiring

and

electrical

connections

of

the

air

conditioning

controls.

the

furnace

is

installed

in

a

closet

or

utility

room,

two

openings

must

be

provided

connecting

to

a

well-

ventilated

space

(full

basement,

living

room

or

other

room

opening

thereto,

but not

a

bedroom

or

bathroom).

One

opening

shall

be

located

above

the

level

of

the

upper

vent

opening

and

one

opening

below

the

of

all

appliances

installed

in

the

room.

For

furnaces

located

in

buildings

of

unusually

tight

construction,

such

as

those

with

high

quality

weather

stripping,

caulking,

windows

and

doors,

or

storm

sashed

windows,

or

where

basement

windows

are

well

sealed,

a

permanent

opening

communicating

with

a

well

ventilated

attic

or

with

the

of

one-quarter

inch

to

the

foot.

The

flue

pipe

should

not

be

smaller

in

cross sectional area

than

the

flue

collar on

the

furnace.

The

flue

pipe

should

connect

to

the

chimney

such

that

the

flue

pipe

extends

into,

and

terminates

flush

with

the

inside

surface

of

the

of

a

peaked

roof.

All

unused

chimney

openings

should

be

closed.

Chimneys

must

conform

to

local,

provincial

or

state

codes,

or

in

the

absence

of

local

regulations,

to

the

requirements

of

the

National

Building

Code.

NOTE:

THE

FURNACE

IS

APPROVED

FOR

USE

WITH

BAROMETRIC

DAMPER

CONTROL.

The

barometric

damper

control,

also

known

as

a

draft

regulator,

is

used

on

conventional

chimney

venting

only.

This

control

automatically

maintains

a

constant

negative

pressure

in

the

furnace

to

obtain

maximum

efficiency.

It

ensures

that

proper

pressures

are

not

exceeded.

If

the

chimney

does

not

develop

sufficient

draft,

the

draft

control

cannot

function

properly.

The

draft

regulator,

when

installed

should

be

in

the

same

room

or

enclosure

as

the

furnace

and

should

not

interfere

with

the

combustion

air

supplied

to

the

burner.

The

control

should

also

be

located

near

the

furnace

flue

outlet

and

installed

according

to

the

instructions

supplied

with

the

regulator.

The

flue

outlet

pressure

(measured

between

the

furnace

and

draft

regulator,

or

the

oil

OPTIONAL

SIDE

WALL

VENTING

O4LD-091A-14-RA-DV

furnace

models

are

manufactured

to

be

installed

as

sidewall

vented

units.

Please

refer

to

Direct

Venting

Instructions,

P/N

240006979

included

with

the

Vent

Kit

for

details.

Sidewall

Venting

(Direct

Venting)

requires

the

use

of

specific

oil

burner;

the

Beckett

AFIIl.

Please

refer

to

Appendix

A,

Table

A2.

Note:

Sidewall

venting

requires

special

attention

to

combustion

air

supply.

There

is

no

natural

draft

in

the

venting

system

between

furnace

cycles;

therefore,

if

the

indoor

pressure

is

negative

relative

to

the

outdoors,

the

vent

terminal

becomes

a

point

of

infiltration.

This

could

lead

to

oil

odour

control

problems.

This

problem

is

rectified

by

the

use

of

ducted

outdoor

air

for

combustion

(semi-sealed

combustion),

using

the

Beckett

AFII

oil

burner.

See

Direct

Vent

Instructions

delay

time

starts

when

the

burner

motor

is

de-energized

at

the

end

of

a

call

for

Blower

shutdown

is

delayed

to

remove

any

residual

heat

from

the

heat

exchanger

and

improve

the

annual

efficiency

of

the

furnace.

The

electronic

fan

timer

board

works

in

conjunction

with

snap

disc

limit

controls,

which

perform

a

safety

function,

and

breaks

power

to

the

oil

ELECTRICAL

CONNECTIONS

The

furnace

is

listed

by

the

Canadian

Standards

Association

under

the

NRTL

(North

American)

Standard.

It

is

factory

wired

and

requires

minimal

field

wiring.

All

field

wiring

should

conform

to

CAN/CSA

C22.1

Canadian

Electrical

Code,

Part

1,

and

by

local

codes,

where

they

prevail.

In

the

United

States,

the

wiring

must

be

in

accordance

with

the

National

Fire

Protection

Association

NFPA-70,

National

Electrical

Code,

and

with

local

codes

and

regulations.

The

furnace

should

be

wired

to

a

separate

and

dedicated

circuit

in

the

main

electrical

panel;

however,

accessory

equipment

such

as

electronic

air

cleaners

and

humidifiers

may

be

included

on

the

furnace

circuit.

Although

a

suitably

located

circuit

breaker

can

be

used

as

a

service

switch,

a

separate

service

switch

is

advisable.

The

service

switch

is

necessary

if

reaching

the

circuit

breaker

involves

becoming

close

to

the

furnace,

or

if

the

furnace

is

located

between

the

circuit

breaker

and

the

means

of

entry

to

the

furnace

room.

The

furnace

switch

(service

switch)

should

be

clearly

marked,

installed

in

an

easily

accessible

area

between

the

furnace

and

furnace

room

entry,

and

be

located

in

such

a

manner

to

reduce

the

likelihood

that

it

would

be

mistaken

as

a

light

switch

or

similar

device.

The

power

requirement

for

the

O4LD-091A-12-RA

and

O4LD-091A-14-RA-DV

modeis

is:

OIL

BURNER

NOZZLES

The

O4LD-091A-12-RA

and

O4LD-091A-14-RA-DV

are

certified

for

multiple

firing

rates,

ranging

from

59,500

to

87,000

Btu/h.

By

manipulating

the

oil

burner

nozzle,

the

furnace

may

be

fired

at

an ideal

rate

for

a

15.

OIL

BURNER

ADJUSTMENT

The

burner

air

supply

is

adjusted

to

maintain

the

fue/

to

air

ratio

to

obtain

ideal

combustion

conditions.

A lack

of

air

causes

"soft"

and

"sooty"

flames,

resulting

in

soot

build-up

throughout

the

heat

exchanger

passages.

Excess

combustion

air

causes

a

bright

roaring

fire

and

high

stack

temperatures

resulting

in

poor

fuel

efficiency.

The

O4LD-091A-12-RA

and

O4LD-091A-

14-RA-DV

furnaces

operate

most

efficiently

with

a

No.

1

smoke

spot

on

the

Bacharach

Scale.

This

is

not

necessarily

the

optimum

setting;

however,

because

dust

will

inevitably

build

up

on

the

air

moving

components

of

the

oil

burner

assembly.

This

will

result

in

decreased

air

supply

with

the

potential

result

of

soot

building

up

in

the

flue

gas

passageways

of

the

heat

exchanger.

Soot

behaves

as

an

insulator

and impairs

good

heat

transfer.

Stack

temperature

will

increase,

and

the

overall

efficiency

will

decrease.

As

a

means

of

avoiding

this

problem,

it

is

advisable

to

adjust

the

air

supply

to

provide

no

more

than

a

trace

smoke

spot

on

the

Bacharach

Scale.

BURNER

PRIMARY

(SAFETY)

CONTROL

The

furnace

is

equipped

with

a

primary

combustion

control,

sometimes

referred

to

as

the

burner

relay

or

burner

protector

relay,

which

uses

a

light

sensing

device

(cad

cell)

located

in

the

burner

housing,

to

monitor

and

control

combustion.

Over

time,

dust

or

combustion

residuals

can

build

up on

the

lens

of

the

cad

cell

impairing

its

response

to

the

flame.

The

cad

cell

should

be

checked

for

cleanliness

and

proper

air

supply

by

first

loosening

the

locking

screw

located

on

the

black

dial

to

the

right

ELECTRODES

Adjustment

of

the

electrode

tips

with

respect

to

each

other,

the

nozzle,

and

to

the

rest

of

the

burner

is

very

important

to

ensure

smooth

start-ups

and

to

permit

efficient

combustion.

Beckett

the

distance

from

the

should

be

1-1/8

inches.

If

a

ceramic

head

is

used,

the

distance

from

A.3

START

UP

The

furnace

should

be

operated

for

a

minimum

of

10

minutes

to

reach

steady

state

conditions

before

fine

tuning

combustion.

The

warm

up

time

is

ideal

for

testing

the

oil

pump

pressure.

Drill

a

1/4-inch

test

port

in

the

venting

between

the

furnace

flue

outlet

and

draft

regulator

(barometric

damper).

Insert

a

stack

thermometer

and

note

the

flue

gas

temperature.

The

flue

gases

should

be

within

a

range

of

350°F

to

450°F.

If

the

flue

gases

are

below

the

range,

it

may

be

necessary

to

slow

down

the

blower

fan.

If

the

flue

gases

are

above

the

range,

the

blower

fan

may

require

speeding

up.

Stack

temperature

varies

directly

with

the

system

temperature

rise.

System

temperature

rise

is

the

difference

between

the

furnace

outlet

temperature

and

furnace

inlet

temperature

as

measured

in

the

vicinity

of

the

connection

between

the

plenum

take-offs

and

the

trunk

ducts.

Temperature

rise

value

is

listed

on

the

system

rating

plate.

Perform

a

smoke

spot

test.

The

smoke

spot

should

not

exceed

No.

1

on

the

Bacharach

Scale.

After

the

air

adjustments

have

been

completed,

re-

check

the

draft

pressure

at

the

test

port

on

the

burner

mounting

plate

as

shown

in

Figure

2.

The

draft

should

be

adjusted

to

OPERATION

OF

OIL

BURNER

Once

the

furnace

flue

pipe,

electrical

and

oil

line

connections

have

been

made,

use

the

following

instructions

to

set

the

burner:

Shut

off

the

electrical

power

to

the

furnace.

Install

an

oil

pressure

gauge

to

the

pressure

port

on

the

oil

pump.

(Refer

to

the

oil

pump

specification

sheet

included

with

the

burner

instructions).

Restore

electrical

power

to

the

furnace.

Start

the

furnace

and bleed

all

air

from

the

fuel

oil

lines.

Close

the

purge

valve

and

fire

the

unit.

Allow

the

furnace

to

warm

up

to

normal

operating

temperatures.

During

this

time,

set

the

pump

pressure

in

accordance

with

the

data

provided

in

Appendix

A,

Table

A-2,

and

A-5.

When

the

furnace

has

reached

“steady

state"

(after

approximately

10

minutes).

Set

combustion

air

damper

to

get

a

TRACE

of

smoke.

Check

the

system

temperature

rise.

The

temperature

rise

is

the

difference

between

the

return

air

temperature

measured

at

a

point

near

the

return

air

inlet,

and

the

supply

air

temperature

measured

near

the

furnace

outlet.

The

system

temperature

rise

is

listed

on

the

furnace

rating

plate.

If

the

temperature

rise

is

too high,

the

airflow

must

be

increased.

If

the

temperature

rise

is

too

low,

the fan

should

be

slowed

down.

Turn

off

the

burner.

Observing

the

duct

thermometer

in

the

supply

air

stream,

note

the

temperature

at

which

the

blower

fan

stops.

The

fan

adjustments

can

be

made

by

moving

the

dipswitch

settings

on

the

timer

control

board

for

fan

off

delay.

To

check

the

operation

of

the

limit

switch,

shut

off

power

to

the

furnace.

Temporarily

remove

the

neutral

wire

from

the

direct

drive

blower

motor.

Restore

the

electrical

power

to

the

furnace

and

set

the

thermostat

above

room

temperature.

After

three

or

four

minutes

of

burner

operation,

the

limit

control

should

turn

the

burner

off.

When

the

limit

function

test

is

complete,

shut

off

electrical

power

to

the

furnace,

replace

the

neutral

wire

to

the

blower

fan

motor,

and

then

restore

power.

The

blower

fan

will

start

up

immediately.

Once

the

temperature

has

dropped

and

the

limit

control

has

reset,

the fan

will

operate

until

the fan

off

time

is

achieved.

The

oil

burner

will

then

resume

operation

and

continue

until

the

thermostat

is

satisfied.

Restore

the

thermostat

setting

to

a

comfortable

temperature.

Set

the

heat

anticipator

adjustment

in

the

thermostat

(if

so

equipped),

by

removing

the

"R"

or

"W"

wire

to

the

thermostat,

then

reading

the

amperage

draw

between

the

two

wires.

Failure

to

remove

one

of

the

wires

from

the

thermostat

while

performing

this

test

could

burn

out

the

heat

anticipator.

Set

the

heat

anticipator

to

the

amperage

measured.

NOTE:

THE

FURNACE

SHOULD

BE

RUN

THROUGH

AT

LEAST

THREE

FULL

CYCLES

BEFORE

LEAVING

THE

INSTALLATION,

TO

ENSURE

THAT

ALL

CONTROLS

ARE

OPERATING

PROPERLY

AND

AS

EXPECTED.

NOTE:

ALL
