ABOUTYOURCENTRALFURNACE

SYSTEM

NORDYNE has been involved in the design of

products for the manufactured home industry

since the ﬁrst manufactured home or trailer

was built.

NORDYNE originated the sealed combustion

system, which separates the furnace combus-

tion system from the living area of the home

and is now a standard for the manufactured

home industry.

NORDYNE engineers developed the ﬁrst central

heating system and the ﬁrst central air conditioner

for manufactured homes.

NORDYNE is dedicated to bringing to its cus-

tomers the ﬁnest heating and cooling comfort

possible. NORDYNE constantly seeks to further

reﬁne its products to continuously provide ex-

ceptional comfort.

Follow the instructions in this booklet carefully

and this appliance will provide many years of

superior performance.

If you wish to cool your home automatically with

a central air conditioning system investigate the

excellent NORDYNE cooling systems available

from your heating and cooling contractor. These

systems are designed to work best with your

NORDYNE furnace and have been carefully

engineered to deliver optimal performance when

mated with NORDYNE manufactured home

furnaces.

NORDYNE also offers water heaters, ﬁreplaces

and ventilating systems speciﬁcally designed for

manufactured housing applications. Ask your

manufactured home retailer, your heating and

cooling contractor, or your distributor for more

information. Write directly to the factory (PO Box

46911, St. Louis, MO 63146) if you are unable

to locate a source for NORDYNE manufactured

housing products in your area.

1. Furnace Location

The furnace area and the vicinity of any other

gas appliance must be kept clear and free of

combustible materials, gasoline, and other

ﬂammable vapors and liquids. Do not store or

use ﬂammable items such as paint, varnish, or

strippers in the vicinity of the furnace.

Do not use the furnace closet or area next to the

furnace as a storage area. This area must be kept

clear, clean, and free of lint. The furnace must

also be kept clear of loose or exposed insulation

materials. Examine the furnace area when the

furnace is installed or when insulation is added.

Some insulation materials may be combustible.

Do not use this furnace if any part has been

under water. Immediately call a qualiﬁed service

technician to inspect the furnace and to replace

any part of the control system and any gas control

which has been under water.

Familiarize yourself with the controls that shut

off the gas and electrical power to the furnace.

If the furnace is to be shut down for an extended

period of time, turn off both the gas and electri-

cal power. For your safety always turn off both

the gas and electrical power before performing

service or maintenance on the furnace.

2. Combustion Air Supply

A furnace needs an adequate supply of com-

bustion and ventilation air for proper and safe

operation. Follow the installation instructions

included with the furnace to properly vent air to the

combustion air inlet and exhaust the products of

combustion to the outside from the exhaust vent.

If the furnace is operated with a restricted com-

bustion air supply, the pressure switch will open,

turning off the gas supply to the burners. (See

Figure 1). DO NOT install a jumper wire across

this switch to defeat its function. If this switch must

be replaced, use only authorized replacement

parts from your authorized distributor.

If the furnace is operated with inadequate com-

bustion air supply, due to sooting of the heat

exchanger, or partial blockage of the vent or

air intake pipe, the ﬂame roll-out control switch

located above the burners may open, turning

off the gas supply to the burners. The ﬂame

roll-out control is a manually resettable device

(See Figure 1). If the ﬂame roll-out control opens

again after once reset, DO NOT install a jumper

wire across this switch to defeat its function. DO

NOT reset the control without identifying and

correcting the fault condition which caused the

control to trip. If this switch must be replaced,

use only authorized replacement parts from your

authorized distributor.

Air openings in warm air registers, and return

air grilles must not be restricted.

CAUTION:

Combustion air must not be drawn

from occupied spaces.

To maximize heat exchanger life, the combustion

air must be free of chemicals which form corro-

sive acidic compounds in the combustion gases.

Some examples of these chemicals are chlorine,

ﬂuorine, and sulphur. Some common sources

of these chemicals are detergents, bleaches,

aerosol sprays, cleaning solvents, and a wide

variety of commercial and household products.

3. Return Air Supply

For M3 models, the return air opening is located

at the front of the furnace. The ﬂoor or platform

on which the furnace is mounted must provide

sound physical support of the furnace with no

gaps, cracks, or sagging between the furnace

and ﬂoor or platform. The circulating air duct-

work must not be connected to any other heat

producing device such as a ﬁreplace insert,

stove, etc. Doing so may result in ﬁre, explosion,

personal injury, carbon monoxide poisoning, or

property damage.

Use an air ﬁlter in the front door to maintain a

clean heat exchanger.

WARNING:

Failure to prevent products of com-

bustion from being circulated into the

living space can create potentially haz-

ardous conditions including carbon

monoxidepoisoningthatcouldresult

in personal injury or death.

4. Vent System

The furnace must always be connected to an ap-

proved vent pipe to carry the furnace combustion

products outdoors. At the beginning and end of

each heating season, inspect the outdoor vent

terminal closely with a ﬂashlight to determine if

any of the conditions listed under the following

warning exist.

5. Maintenance

Proper maintenance is most important to achieve

the best performance from this furnace and

should be performed by a qualiﬁed service

technician. Follow the maintenance schedule

(see Table 1) and the following instructions for

years of safe, trouble free operation.

• Donotplacecombustiblematerialsonor

against the furnace cabinet.

• Donotstoregasolineoranyotheram-

mable vapors and liquids in the vicinity of

the furnace.

• Annuallyinspectthe furnace,ductwork,

and vent system for signs of physical

deterioration.

• Changeorreplacetheairltersmonthly

during any period when the circulating

blower is operating regularly.

• Alwaysreplacethedoorsonthefurnace

after servicing or cleaning/changing the

ﬁlters. Do not operate the furnace without

alldoorsandcoversinplace,exceptto

check burner operation.

• Avoidoperatingthefurnacewhenwindows

and doors are open.

• Be sure that the thermostat is properly

installed and is not being affected by drafts

or heat from lamps or other appliances.

WARNING:

Never operate the furnace without

a ﬁlter in place. Dust and lint in the

return air can build up on the internal

components, resulting in a loss of

efﬁciency, equipment damage, and

possible ﬁre.

Air Filter — An air ﬁlter is supplied with the

furnace as shipped from the factory. The ﬁlter

must be removed and cleaned monthly during

the heating season to ensure proper furnace

operation. The ﬁlter is easily cleaned with soap

water or with vacuum cleaner. New or newly

renovated homes may require more frequent

changing until the construction dust has been

removed.

Always replace the ﬁlter with a ﬁlter of the same

size and type as the ﬁlter being removed.

Always replace the door(s) on the furnace after

servicing or cleaning/changing the ﬁlters. Do not

operate the furnace without the door(s) in place.

To clean or replace the ﬁlters, proceed as

follows: (See Figure 2).

1) Turn furnace electrical supply to OFF.

2) Remove furnace main door.

3) Release ﬁlter retainer wire.

4) Pull out ﬁlter.

5) Vacuum or wash ﬁlter with soap water and

allow to dry.

6) Place ﬁlter and retainer wire in door.

Lubrication — The bearings in the circulating

air blower motors used in these furnaces are

pre-lubricated and sealed at the factory. No

further oiling of the bearings is required for the

life of the motor.

BlowerCompartment— The blower compart-

ment should be cleaned monthly during the

heating and cooling seasons to remove any dirt

and lint that may have accumulated in the com-

partment or on the blower and motor. Buildup of

dirt and lint on the blower and motor can create

excessive loads on the motor resulting in higher

than normal operating temperatures and possible

shortened service life.

BurnerMaintenance— Check the burner ﬂames

at the start of every heating season. Set the

thermostat to a temperature setting above the

room temperature. Remove the front door from

the furnace, close the door switch (see Figure 1),

and visually inspect the burner through the view

hole to make sure that the ﬂame is drawn into the

center of the heat exchanger tube (see Figure

3). In a properly adjusted burner assembly, the

ﬂame bends up at the end of the heat exchanger

tube, and the end of the ﬂame will be out of sight

around the bend. The ﬂame color should be blue,

however some light yellow streaks may occur on

the outer portions of the ﬂame.

CAUTION:

Some components in the burner ves-

tibule are at high temperatures while

the burners are operating. Use caution

to avoid personal injury.

Inspect the burners, mounting brackets, and all

other parts in the vestibule for signs of deteriora-

tion. The burner vestibule should be vacuumed

clean and inspected annually. Open the door

switch and replace the front door.

CAUTION:

Do not strike any of the internal elec-

trical components while vacuuming.

6. Operating Instructions

READ THE SAFETY INFORMATION ON

PAGE8BEFOREOPERATING.

WARNING:

Should overheating occur, or the gas

supply fail to shut off, shut off the

manual gas valve to the furnace before

shutting off the electrical supply.

manuel d’alimentation en gaz du gé-

nérateur d’air chaud avant de couper

l’alimentation électrique.

These furnaces are equipped with roll-out limit

switch(s), a vent safety switch, and a pressure

switch (See Figure 1). The pressure switch veri-

ﬁes that the ﬂame is receiving combustion air. If

the ﬂame is not drawn into the heat exchanger

tube, the roll out limit switch or ﬂame sensor, will

shut the furnace down.

The vent safety switch shuts the furnace down if

the vent becomes blocked or restricted.

Furnace Fails To Operate — If the furnace does

not operate, check the following:

1) Is the thermostat operating properly?

2) Is the front door in place?

3) Is the furnace disconnect closed?

4) Has the circuit breaker tripped (or fuse

blown)?

5) Is the gas turned on?

6) Is the ﬁlter dirty or plugged?

If the combustion and circulating air blowers

are operating, and items 1 through 6 have been

checked without identifying the cause of the

problem, press the red reset buttons on the vent

safety and the roll out limit switches. See Figure 1.
