ROOF

JACK

A close

inspection ol

the cut-a-way

drawing

of the

roof

jack

and

furnace shown

in

Figure

1,

will show

that

both

the

flue

pipe

and the

combustion

air

tube

must

be

securely

attached

to the

furnace.

This

is to

insure a

complete

circuit

for the combustion

air and

flue

gases.

The

.f

urnac'e

will nol

operate

unless

the

roo/

jat'k

has

been

properlf installed.

APPLICATION

Figure 1

APPLICATION

The

telescoping

flue

pipe

must be firmly seated

on the

furnace

flue

collar

and

secured with

a sheet

metal

screw. The telescoping

combustion

air tube

should be

pulled

down

and sealed

against

the top of the air

chamber

located inside the

top of

the

furnace.

The straps,

attached

to the

combustion

air tube. should

be

secured

to the top of the

furnace with

sheet

metal screws.

Sheet

metal

screws

should

not be longer

than

%

inch.

Problems

assoc'ialecl

u'ith intproper roo./

jack

installation.

Problem:

The main

burner comes on

normally.

Main burner flame and

pilot

flame begins

to lift

immediately,

and

floats to

the

top

of

the

heat

ex-

changer

then

goes

out.

Cause:

This is an indication

that:

L The inner

flue tube is missing or has not

been

securely

sealed to the flue outlet of the

furnace,

2.

blocked flue.

This results

in

a

recirculation

of

flue

gases

and

extinction

of main

burner and

pilot.

Solution:

l. Replace

inner flue tube,

2. Secure

the flue tube

to the flue outlet of

the

furnace,

3.

Remove

block.

Problem:

Pilot outage.

Cause:

Combustion air

tube not

installed

or

not

sealed against

the top of the air

chamber

located

inside the top of the

furnace.

Reason:

l. Different

pressure

zone. Downdraft

will ex-

tinguish

pilot.

2. Drawing

combustion

air

from inside the

home.

Defeats

the

purpose

of

sealed combustion.

Solution: Combustion air

tube should be

installed

and

sealed

against

the top

of

the air chamber

located

inside

the

top

of the

furnace.

O.D.

copper

tubing

If

the

piping

length exceeds

40',

use

't7^"

black

iron

pipe

or

'/a"

copper

tubing.

When using

natural

gas,

branch tubing

may be copper

internally

tinned or copper

tubing containing

not more

than

75

percent

copper.

When using

L.P.

gas,

tubing

may be

type K.

Be

sure

to check

local authorities

for

any

other

requirements

concerning

gas

piping.

It is

recommended

that a

main shut-off

valve be

located in

the

gas

supply

line external

to the

furnace.

This shut-

off

valve

is required by

AGA as well

as

some

local

codes.

When

making the connection

at the

gas

control

valve,

use a

wrench on the

inlet side to

prevent twisting the

valve body which

could

result in service

problems.

After

connections

have been

made, be sure all

joints

are checked

with soap

suds to detect

any

leaks. This

should also

include a check of

the

furnace controls

and

piping. NEVER CHECK FOR

LEAKS

WITH

A LIGHTED

MATCH.

CAUTION:

DO NOT TEST THE

THE

7660-528

BURNER

The 1660-528 burner is a

mono-port type burner with

a stainless steel

flame spreader

mounted

above

the

burner

port

to spread the flame out

nearer

the

walls

of

the

heat exchanger. Just

inside the burner

port

is

a flame retainer that

holds

a

portion

of

the

gas

flame

down around the burner

port.

The flame

should

be slightly

yellow

while the

furnace

is

operating.

The

burner

flame should

not rumble

or

roar like a blow torch

(furnace

receiving too

much

combustion

air). The air

shutter

adjustment

may be

pushed

in

to

provide

more

primary

air and

pulled

out

to reduce the amount of

primarl'

air being delivered

to

the burner

flamc. This

adjustment

depends upon the

average winter

temperature

and

thc

geographical

loca-

tion of the

furnace.

AIR

REQUIREMENTS

The

is

dependent

upon satisfying

the

requirements

for four

types

of air.

l.

Comhustion

air

As seen

in the

cut-a-way

vlew

of the

PRESIDENTIAL

furnace, combustion

air

is

supplied to the

burner through

the

roof

jack.

Down the

back of

the furnace

to an area

below

the combustion

chamber.

Primary

air

for

combustion

is

drawn

into'

the

venturi of

the burner by

the action

of

gas

velocity

(aspiration)

in the venturi.

This

air

and

gas

mixture

is thoroughly

mixed in the

mixing chamber

and

discharged

upward against

the

flame

spreader where

it is ignited by the

pilot.

Combustion

is

completed

with the addition

of secon-

dary

air around

the outside

of the

burner

into the

combustion

chamber.

The hot

products

of combustion

then

rise

in

the

heat

exchanger and

pass

to the

outside

through

the

flue

and

roof

jack.

All combustion

air

is taken

from the

outside

resulting

in

a

system

referred

to as sealed

The

operation

of the

Fresh air

-

Some coaches,

due

to

location, may

have an excessive

moisture

problem. ln some cases

the moisture

problem

may be so

bad that condensa-

paint

jobs.

When the air

is warrn, the

moisture

in

the

more

moisture than

cold air, air containing

too

much

water vapor condenses

to

form frost or

water when-

ever

it

comes

in

contact

with

a

cold surface.

One of

the most common

illustrations

of

visible condensa-

tion

in the coach

is

the

formation of water

or

frost

on the

windows.

Cooking,

washing, bathing,

etc., all add

moisture

to

the air,

and

large amounts show

up as

condensation.

The small

rectangular chute

on the

bottom of the

furnace brings

in fresh air

to the circulating

blower.

The fresh air

which

is brought

into the circulating

blower

is

then distributed

as

warm air

through the

duct system.

This cool outside air,

after

being

warmed,

is

capable

of absorbing

moisture,

thus

helping to reduce condensation.

Return

air

The louvers on

the

top

front

of the

furnace

admit

return air.

Return air

must be

pro-

vided

back

to the

circulating

blower

in order

to

provide

air distribution.

Do

not enclose

the

lurnace

or otherwise

obstruct

these

louvers.

To

'do

so will

cause

the

furnace

to limit and

go

to

pilot.

The Presidential

furnaces are

designed

to

give

superior air-handling

capabilities.

This results

in an

air

temperature

rise of

165'F. compared

to

the

200'F. rise that the Solar

Paks were designed

for.

lf

you

use

less than

200 square

inches

free

area

return

grille

you

are reducing

the air

flow across the

heat exchanger and

just

asking

for service

problems

resulting in high temperature

cycling

on

heating.

To

avoid

operational

problems

on the

7660

furnace,

the 7660-5491

return air

grille must

be

used.

This

grille

has

200 square

inches of free area

and the use

of less

free

area

can

result in operational

problems.

INSTALLATION

INSTRUCTIONS

FAN

SWITCHES

'I'he

furnace is equipped

with one

fan

switch

located

at the

top of the control

panel. This

switch

is

a

nor-

mally

open

switch

that closes

with a

rise

in tempera-

ture.

The

fan switch

is

a

disc

type switch

that

is

calibrated

to close at

105', and open

at 90o.

As in the case ol a

limit switch,

the

temperature

on

the

fan switch does

not

necessarily

mean that

the air

will

be

the same

temperature.

A fan switch,

due

to

its loca-

tion

on the

furnace, might actually

start

the blower at

an

outlet air

temperature

that

is

above

the calibrated

temperature.

The disc switches

used are

marked

to indicate

the tem-

perature

at which

the switch

will open

or close

and

the type switch

being used.

For example,

a marking

of

Fl40-30

means that

the switch

is

a

fan switch set

to turn

the blower

on at

l40o

and

shut

of at

The

lower limit

Some

common

causes

of

ANTICIPATION

The operation of

a

low voltage

thermostat

based solely

on

mechanical

means,

generally

results

in wide varia-

tions

in temperature

in the conditioned

area

whether

the

application

is for heating or

cooling.

To insure a

more

precise

control

of area

temperature,

low voltage

thermo-

stats

contain

heating

and cooling

anticipators.

In

addition

to

improved

room temperature

control,

heat

anticipation

contributes

to better

air circulation.

The

burner

may cycle

on and off

several

times

during

one

cycle

of the

fan. Since

heat

anticipators

are

powered

and

effective

only during

the

heating

cycle,

they are

placed in series with

the control

contacts.

When the

contacts

are

closed,

power

is supplied

to the

heat

anticipator

resistor.

MANUAL

SWITCHING

OPERATIONS

Generally,

a

sub-base used

to

control both

heating

and

cooling

equipment

will contain

two switches,

one

marked

"FAN"

and one

marked

"SYSTEM."

FAN

SWITCH

ON Constant

fan. The fan will

run continuously

re-

gardless

of

the thermostat

demand.

AUTO

The fan runs only as

required

by the system

operatlon.

SYSTEM

SWITCH

HEAT

-

Heating

system

only,

operates

in response

to

the

thermostat.

OFF

Heating system

and

cooling

system

both off.

COOL

-

Cooling

system

only,

operates

in

response

to

the thermostat.

CAL/TION:

Care

should

always

be taken

in the align-

ment of

the

thermostat

attaching

screws,

as they

may

also

serve

as

terminal

connectors.

If threads

are

stripped,

a

poor

electrical

connection

will result.

INSTALLATION

AND SERVICE

l. A low

voltage

thermostat

is a

precision instru-

ment and

should

be

treated as

one.

Care

must be

used

to

insure a

level

installation

with

thermostats

using

mercury bulbs.

2. Mount

on a solid

wall.

3.

Locate the

thermostat

on an

inside

wall

four to

five

feet above

the

floor in an

area

free

from

drafts

and direct

sunlight.

Do

not locate

where directly

affected

by

lamps, fireplaces,

appliances,

or on

walls

containing

hot or cold

pipes,

ducts,

chimneys.

4. Be

sure anticipator

matches

or is

adjusted

to

match current

(amp)

draw

of

equipment

being

controlled.

5.

Make

all

wiring

connections

clean

and

tight'

lf a

heating

system

has an

improperly

sized

anticipator

and

excessive

heat

is

generated in

the

thermostat,

the

result

is

a

short

"on"

cycle.

During

periods when

the

system

is

running

close

to its

full capacity,

more of

the

heat

sensed

by

the

bi-metal

is

from

the

anticipator

than

from

room

air;

and

the controlled

area

tempera-

ture

will

progressively

decrease.

THERMOSTATS

Insufficient

heat anticipation

in a

heating system

results

in the bi-metal

lagging behind

the

room temperature

change.

This will cause

longer

"on"

and

longer

"ofl'

periods

with

a

resultant

larger

room temperature

varlatlon.

A common

heating valve

current draw

is 0.4 amps,

and this

should be

matched on

any

adjustable antici-

pator.

If the adjustable

anticipator

is set appreciably

higher,

for example

rJ.1

amps,

it

will increase

the

room temperature

variations

by

3oF. or

4oF. and cause

longer running cycles.

For longer

"on"

periods,

set the

heat anticipation ad-

justment

pointer

at slightly

higher amp

value. For

shorter

"on"

periods,

set the

pointer

at

slightly

lower

amp

value. Move

only

t/q

to

/z

scale

division at a time.

(Never

set

the

pointer

at

more than

I

%

scale

divisions

below the amp

rating of the valve or

relay

current

rating.)
The

anticipation

function

in a cooling

thermostat

is the

reverse of

its heating application.

The cooling

antici-

pator

is

powered

during the

"ofl'

cycle.

As the

room

temperature

increases,

heat

is

applied

to the

bi-metal

decreasing the

time

necessary for

the bi-metal to

close

the contacts.

Excessive cool anticipator

temperature

results

in shorter

"offl'

periods,

consequently,

more

frequent cycling

of the cooling

equipment.

Insufficient

anticipation

in

a cooling

thermostat

causes

long

"ofl'

and

cycles

resulting

in

larger temperature

variations

in the room.

without their

own

transformer.

If

you

are adding

air conditioning

to a 7600-700

series

furnace,

the

condensing

unit

must contain

a transformer.

In

the event

that there

is no transformer

in

the condensing

unit,

one must

be ordered

(pln

62723a5

l) and

installed. The

various

wiring

hook-ups may

be

found below

under

"Wiring."

The

7600400

series

Presidential Gas

Furnaces

have

40 V.A.

transformers

factory installed.

This

series

furnace

was de-

signed

to accommodate

addon

air conditioners

with no

transformer

in

the

condensing

units.

If adding

a condensing

unit to

this series

furnace, and

the

condensing

unit

does have

a transformer,

it must

be disconnected

and

removed.

For

correct

wiring

procedures,

see

the

"Wiring"

section

below.
