CAUTION

After

the

furnace

operating

with

filters

installed

and

all

cabinet

panels

are

in

place,

check

the

temperature

rise

through

the

unit

to

insure

it

is

within

the

range

specified

on

the

furnace

rating

plate.

If

it

is

not,

adjust

blower

until

the

temperature rise is within specified range.

FIELD INSTALLED EQUIPMENT

Wiring to be done in the field between the furnace and devices
not

attached

to

the

furnace,

or

between

separate

devices

which

are

field

installed

and

Тура

T

wire

[63^F

rise

(36^C)J

when

installed

in

accordance

with

the

manufacturer's

instructions.

Refer to wiring diagrams.

ELECTRICAL POWER SUPPLY

Run a separate 120 volt, 15 ampere, 60 Hz, AC circuit from a
separate

fuse

or

circuit

breaker

in

the

service

entrance

panel.

Locate

a

shut

off

switch

at

the

furnace.

Make

connections

from

this

switch

to

furnace

junction

box

as

shown

in

the

furnace

wiring diagram.

ELECTRICAL GROUNDING

A.

Recommended Grounding Method

When

installed,

the

furnace

must

be

electrically

grounded

in

accordance

with

local

codes

or

in

the

absence

of

local

codes,

with

the

National

Electrical

Code,

ANSI/NFPA

No.

70-1981. Use a #19 Awg copper wire from grounding lug or

green

ground

wire

on

the

furnace

to

a

grounded

connection

in

the

service

panel

or

a

property

driven

and

electrically grounded ground rod.

B.

Alternate Grounding Method

If

the

recommended

grounding

method

is

impossible,

permanently

ground

the

furnace

from

the

ground

connector

to

a

grounded

cold

water

pipe

using

a

separate,

green

colored,

insulated

conductor

of

appropriate

size.

THIS,

HOWEVER, IS NOT RECOMMENDED.

NOTE:

DO

NOT

ground

to

a

gas

supply

pjpe.

DO

NOT

connect

to

electric

power

supply

until

appliance

is

permanently grounded.

THERMOSTAT

Install

the

thermostat

in

accordance

with

instructions

packed

with

it.

Locate

the

thermostat

4-1/3

feet

from

the

floor

on

an

inside

wall

away

from

drafts,

warm

air

registers

and

floor

or

table lamps. Refer to furnace wiring diagrams for connections.

All

34V

wall

thermostats

have

heat

anticipators

to

compensate

the

thermostat

for

various

system

controls

and

allow

the

best

possible

cycle

rates.

Some

anticipators

are

fixed

and

require

no

adjustment.

However,

the

majority

of

wall

thermostats

have

adjusuble

anticipators

and

DO

REQUIRE

ADJUSTMENT

to

match

the

current

rating

of

the

gas

valve.

The

anticipator

setting should be 0.80A.

Failure

to

adjust

the

anticipator

lever

to

correspond

to

the

actual

current

draw

through

the

thermostat

will

cause

severe

short

cycling

if

set

too

tow

and

room

temperature

may

never

attain

the

thermostat

set

point,

and

if

set

too

high,

will

cause

room temperature to overshoot the set point.
