Do not install this furnace in a mobile home or trailer.

Always connect this furnace to a chimney and vent to the outside. Never vent to another room or inside a building.

Do not connect this furnace to an aluminum Type B gas vent. This is not safe and is prohibited by the

National Fire Protection Association Code. This furnace requires a masonry or listed factory built chimney for residential type or building heating appliance chimney. Use a 6" diameter chimney or larger, that is high enough to give a good draft. (See Page 8)

Be sure that if a masonry chimney is used, it is safely constructed and in good repair. Have the chimney inspected by the Fire Department or an inspector.

Inspect chimney connector and chimney before and frequently during the heating season for any deposit of creosote or soot which must be removed (see Chimney Maintenance, page 21.)

Provide air for combustion into the room where the furnace is located. If the intake is not in the same room, air must have free access to the room.

CAST IRON PARTS MUST BE "SEASONED" TO AVOID CRACKING. BUILD ONLY SMALL FIRES

ON FIRST USE.

To prevent injury, do not allow anyone to use this furnace who is unfamiliar with the correct operation of the furnace.

For further information on using your furnace safely, obtain a copy of the National Fire Protection

Association (NFPA) publication "Chimney's, Fireplaces and Solid Fuel Burning Appliances" NFPA

211. The address of the NFPA is Batterymarch Park, Quincy, MA 02269.

Keep the ashpit section free of excess ashes. Do not allow ashes to stack higher than the sides of the ash pan.

DISPOSAL OF ASHES - Place ashes in a metal container with a tight fitting lid. Keep the closed container on a noncombustible floor or on the ground, well away from all combustible materials. Keep the ashes in the closed container until all cinders have thoroughly cooled. The ashes may be buried in the ground or picked up be a refuse collector.

CAUTION - The special paints used on your furnace may give off some smoke while they are curing during first few fires. Build small fires at first. The metal used in construction of the furnace and duct work has a light coating of oil. This could give off smoke and/or odors from registers when furnace is used for the first time. This should disappear after a short period of time. Once this burn-off has occurred, it should not reoccur.

CARING FOR PAINTED PARTS - This furnace has a painted outside jacket, which is durable but it will not stand rough handling or abuse. When installing you furnace, use care in handling. Clean with soap and warm water when furnace is not hot. DO NOT use any acids or scouring soap, as these wear and dull the finish. DISCOLORATION WILL OCCUR IF THE FURNACE IS OVERFIRED.

FOLLOW OPERATING INSTRUCTIONS CAREFULLY.

15.

Keep the feed and ash doors closed at all times except while tending the furnace.

Your Furnace is designed to be installed in a parallel air flow arrangement with a gas or oil-fired forced air upflow-type central furnace, or it may be installed as a central furnace.

HOW THE FURNACE FUNCTIONS

Your Supplemental Furnace is designed to be a supplemental or central heating source for your home. This solid fuel furnace may be installed in conjunction with a properly operating central furnace that is listed or certified in accordance with nationally recognized safety standards and equipped with the required controls and other safety features and which has been installed with appropriate standards of

National Fire Protection Association with installation clearances specified in the furnace nameplate marking. The installation must be accomplished by a qualified agency (one who is engaged in, and is responsible for, or is thoroughly familiar with the installation and operation of the gas, oil, and solid fuel burning heating appliances, who is experienced in such work, familiar with all precautions required, and has complied with all the requirements of the authority having jurisdiction.) The installation shall be in strict accordance with the manufacturer's installation instructions furnished with the solid fuel furnace.

The chimney connector of the furnace is to be installed to provide clearances to combustible material not less than specified in the individual classifications and marked on the furnace. The chimney connector must be connected to a chimney suitable for use with residential type or building heating appliances which burn solid fuel.

The furnace is designed to operate in either parallel or series air flow arrangement with the central furnace or as a central furnace.

PARALLEL INSTALLATION: The design is such that when the blower comes on, the blower on the central system also comes on.

The blower will only come on when the temperature in the plenum has reached the setting on the blower control. This is to insure that there is sufficient warm air in the system to make it efficient for the unit to operate. When the central system thermostat calls for heat, the central system will operate by the burner igniting and the blower coming on. It is possible that both systems will operate simultaneously. It is recommended that for the most efficient use of your Supplemental Furnace, that it be fired as much as possible in order to reduce the demand on your existing central heating system. This unit has an optional motorized natural draft kit that operates from a wall thermostat. When the temperature falls below the setting on the wall thermostat, the motorized natural draft will open to increase heat.

The warm air supply outlet of the supplementary furnace shall not be connected to the cold air return inlet of the central furnace because the possibility exists of components of the central furnace overheating and causing the central furnace to operate other than is intended.

SERIES INSTALLATION: This type of installation uses only the blowers of the existing central furnace. The solid fuel fan/limit control must also control the functions of the existing furnace. All electrical power must come from a single branch circuit (see Fig. 15).

CENTRAL FURNACE INSTALLATION: As a central furnace, the unit functions independently of any other system. The blower will come on when the plenum temperature reaches the setting on the blower control.

Installation

Please see all methods of Installation in Appendix at the rear of this booklet.

This is a furnace, not a free standing stove.

You must direct heated air from 8" outlets away from the furnace, or it will not function properly.

1. This installation must be done by a qualified heating equipment installer.

2. The installation is to be done in compliance with National Fire Protection Association installation standards: No. 89M, 90B, 211, 70 (National

Electric Code) and Uniform Mechanical Code

913, 6-4, in the states where applicable. (Their code offers connecting smoke pipe connectors into chimney with other fuel burning appliances.)

3. Rooms large in comparison with size of the appliances:

a) Wood or Coal Burning Furnace needs air for combustion and circulation to house.

b) Provision must be made to make up this air and not starve gas or oil furnace of combustion air.

c) Have "Authority Having Jurisdiction" determine that air is of adequate makeup. (Reference

N.F.P.A. Nos. 30 & 54, Code for Installation of

Gas & Oil Equipment)

4. Have "Authority Having Jurisdiction" to inspect all chimneys and installations for adequate venting and for compliance with standard and local codes and regulations regarding installation of wood burning appliances.

5. Installation of Supplemental Heat Application to Existing Central System. (See Fig. 2 for typical installation.)

a) Place Wood or Coal Burning Furnace so that the chimney connector will be as short as possible and avoiding unnecessary sharp turns in the smoke pipe connector and the installation of devices that would create excessive resistance to the flow of flue gases.

b) Locate the Wood or Coal Burning Furnace as close as practical to the existing central hot air heating system, maintaining clearances as stated on the label below the fuel door.

c) Clearances from combustible materials must be complied with as stated on the label below the fuel door:

Unit to Combustible:

Front: 48"

Back: 30"

Sides: 12"

Plenum to Ceiling: 6"

Pipe to Combustible:

Sides: 21"

Back: 18"

13

The installation must be made only on a noncombustible floor.

d) Install the smoke pipe connector to the chimney with 26-gauge pipe and elbows (to be purchased separately), maintaining the proper clearances for the specific model. Make sure that the proper clearances as stated on the label and earlier in this manual are maintained. Seal the smoke pipe in the chimney with furnace cement.

(The chimney connector shall be securely supported, and joints fastened with sheet metal screws or rivets.)

e) Install 8" diameter heat pipe to plenum of the central hot air furnace. Use 26-guage pipe and connectors (to be purchased separately). (See

Fig. 14) If central air conditioning is installed in the plenum, install heat pipe above the air conditioning unit. Secure heat pipe connection with supports and sheet metal screws.

f) Connect electrical supply in the electrical junction box that is mounted on the back of the

Wood Burning Furnace. See Wiring Diagram (Fig.

12). Remove the cover from electrical junction box connect power supply wires to wires designated, using wire nuts. The power cord supplied may be used for installation, if permitted by local codes and regulations. If the power cord supplied cannot be used, the power supply wiring must be

90 degrees Centigrade in a metal cable and should be completed by a qualified installer complying with NFPA Standard No. 70 and local codes.

g) Optional Plenum Fan Control Switch (Part

No. 11PCS) is available for installation on the plenum of central hot air heating furnace. The purpose of this switch is to activate the circulating fan of the central hot air heating furnace when the temperature in the plenum exceeds 120 degrees

Fahrenheit. The switch would activate the fan at

120 degrees Fahrenheit, and would shut off the circulating fan when the temperature in the plenum is reduced to 100 degrees Fahrenheit . This avoids overheating the plenum.

The electrical supply for operation of this fan control switch is to be obtained from same electrical supply as the central hot air heating system.

(See Fig. 14) Follow the instructions of the wiring diagram (Fig. 15). Do not make connections across Limit Control in the furnace.

Make electrical connections in electrical junction box presently mounted on the furnace. Make electrical connections in accordance with NFPA

Standard No. 70 and local codes in the power supply junction box (See Fig. 15). The wiring to complete the connections should be 18 AWG minimum copper and 90 degrees Centigrade in a cable.

operating instructions

Your Clayton Furnace is capable of burning Wood or Coal.

WOOD BURNING: (1)use Hardwood, 18" to 26", split and air dried (seasoned) for six months. (2) set thermostat to "HIGH" before opening feed door. (3) add wood to a convenient level.

BURNING COAL: Clayton Furnaces are capable of burning Bituminous coal and Anthracite coal. Anthracite is perhaps the best coal fuel because its long even burn time, high heat output, and cleanliness make it a good choice for the home. However, keep in mind it is a much more difficult fuel to use, requires more care and patience, is not so widely available, and is usually much more expensive than Bituminous.

SIZE OF COAL: Most sizes of Bituminous Coal will work in the Clayton Furnace; for best results we recommend large "nut" coal to small "egg" coal (1-3/4" diameter to 4" diameter). When burning Anthracite, use "egg" or "broken" with sizes between 2-5/16" thru 4-3/8". Note that it is important to the long life of your stove to buy coal which has been sized and cleaned. Cleaning insures removal of rocks and other minerals. Never use coal smaller than 1" or larger than 5" in diameter. Small sized coal will smother the fire. Too large a size of coal will not burn well.

STOVE OPERATION: All coal fires should be started with wood which will allow the fire to get hot enough to ignite the coal. The best ignition fires utilize dry pine or other resinous soft woods as kindling, with hard wood (oak, hickory, ash) added to increase the heat prior to addition of the coal.

BURNING BITUMINOUS: Once your kindling and wood fire has produced a bed of well established coals, start adding coal in layers allowing each to ignite before adding more. Bituminous has a high volatile content and, as a result, should be fired with the "conical method" - with the highest portion of your firebed in the center of the firebox.

The first flames will be long and generally orange or yellow and produce quite a bit of smoke. As the gases burn off the flames become shorter, change color and produce less smoke.

Once the fire is WELL ESTABLISHED add coal to the center of the firebox forming the cone. Burning in this fashion allows heat to drive off the volatile gases, and turbulence created increases the burn efficiency. There will have to be some experimenting with the individual setup as no two chimney's or installations are going to be the same. Just remember to allow enough secondary air to enter the firebox and keep the stove pipe damper open so that volatiles are properly burned. Before refueling, take the time to break up the cone a little with a poker, especially if it has caked over or formed a crust. But, be careful not to mix the coal as this increases the chances of forming clinkers. When shaking the grate(s) be gentle. Just a few short movements - a couple of "cranks" is better than a lot of agitation.

The objective is to remove a small amount of the ashes without disturbing the fire. Stop when you see a glow in the ashes or the first red coals fall into the ash pan. Excessive shaking wastes fuel and can expose the grate(s) to very high temperatures which can cause warpage or burnout.

For overnight operation (long duration burn time) shake the fire and add coal, retaining the center cone. Once the volatiles are burned off, close the feed door and adjust the stove pipe damper. Then adjust the thermostat to the desired heat level.

More MAINTENANCE will be need with bituminous than with anthracite coal as more soot will collect on heating surfaces and in pipes, requiring more frequent cleaning.

ANTHRACITE: Before starting the fire open - the stove pipe damper, turn the automatic thermostat to high, open the ash pit door and feed door, place newspaper and finely split kindling on the grate, light the paper, add larger hard wood after the kindling is burning brightly. Caution: Never use gasoline, lantern fuel, kerosene, charcoal lighter

fluid, or other flammable liquids to start or freshen up a fire in any heater. Place the larger pieces of wood on the fire so that they are slightly separated and form a level for the addition of coal. It will take 10 to 20 minutes before this wood is thoroughly ignited. Adding coal too soon will cut the air supply and smother the fire.

18

Add a thin layer of coal (preferably smaller chunks) to the wood fire, being careful not to disturb it too much or cut off the draft. Then, add a second heavier layer after the coal is ignited and burning well. If necessary, add a third layer to bring the coal up to the top of the front liner (not above!). Be sure to close the ash door.

Before adding further fuel, be sure to leave a red spot of glowing coals in the center of the firebox to insure that the fire has not been smothered and to help ignite the gases given off by the new charge. A deep charge will give a more even heat and a longer fire, but it may take one to two hours before the whole bed is fully ignited.

When the fire is well established and the room is becoming warm, partially close the dampers. Some experimenting will have to take place with each particular setting of all dampers and controls as the chimney provides the draft necessary to not only exhaust the smoke, but to pull combustion air into the heater as well - and no two chimney's perform the same. Under ideal draft conditions one should be able to turn the secondary air supply on the feed door

(some models) to a near closed position - but leave the ash pit damper at least partially open to prevent the fire from going out. Adjust the stove pipe damper to reduce the draft on the fire. With anthracite there will be short blue flames above the coal, except when the fire is started or a new charge is added. If, however, there is no flame then the fire needs more air from the bottom (unless it is near the end of its burn cycle and needs to be recharged).

Only when the coal is burned down to half its original depth it is time to add fresh coal. When doing so, open the stove pipe damper and turn the thermostat damper to high, which will allow the fire to burn off any accumulated gases.

Open the feed door, and with a small rake, hoe, or hooked poker pull the glowing coals to the front of the firebox.

Try not to disturb the fire too much. Next, add a fresh charge to the back being careful not to seal off the top. Close the feed door, but leave the spin damper (or thermostat) open for a few minutes until the volatile gases have burned off. It is not necessary to shake down the ashes each time you refuel the furnace. Experience will be your best teacher.

BANKING THE FIRE: For extended operation, such as overnight, the fire will need to be banked. To do so heap coal up along the sides and back of the firebox so that the fire gradually burns it over a longer period of time. The intensity of the fire will also be reduced without letting it go out. Follow the same procedure as for refueling. If possible, avoid shaking, as a heavier layer of ash will help reduce the intensity of the fire during this time. After loading let the fire establish itself for about 30 minutes. Then close your damper and automatic control to the point where the house does not become too cold. It is important that you begin banking early enough before retiring or leaving that you can make necessary adjustments after the fire is well established.

To revive a coal fire that is almost out, (1) open the ash door and stove pipe damper and close the spin damper on the door to get a good draft through the grate. (2) place a thin layer of dry coal over the entire top of the fire. DO

NOT POKE OR SHAKE THE FIRE AT THIS TIME! (3) after the fresh coal has become well ignited shake the grate

(just a little), refuel.

DO NOT burn coke, charcoal, high volatile bituminous coal, sub bituminous, lignite or cannel coal (sometimes called channel coal or candle coal). NEVER burn wax or chemically impregnated sawdust logs - their intended use is for fireplaces only. NEVER fill the stove or furnace above the firebrick or cast iron liner.

The temperature in the plenum of the warm air furnace at which the blower turns on or turns off, is controlled by the setting of the pointers in the blower limit control (See Fig.

12). These pointers may be adjusted through their entire range of settings to achieve the desired warm air output from the furnace. (See Fig. 16 Below)

1.

2.

3.

Move both pointers towards the right (counter clockwise) - this increases the temperature setting at which the blower will turn on and off.

Move both pointers towards the left (clockwise) - this decreases the temperature setting at which the blower will turn on and off.

Move pointers away or apart from each other- this increases the time that the blower will run on each warm cycle.

FIG. 16 service hints

Do not expect a furnace to draw. It is the chimney that creates the draft. Smoke spillage into the house or excessive build-up of water or creosote in the chimney is not functioning properly. Correct the problem before using furnace. Possible causes are:

4.

If the chimney is operating too cool, water will condense in the chimney and run back into the furnace. Creosote formation will be rapid and may block the chimney. Operate the furnace at a high enough fire to keep the chimney warm preventing this condensation.

1.

2.

3.

The connector pipe may be pushed into the chimney too far, stopping the draft (Fig. 6).

5.

Do not connect two furnaces or a stove and a furnace into the same chimney flue.

The chimney used for a furnace must not be used to ventilate the cellar or basement. If there is a cleanout opening at the base of the chimney, it must be closed tightly.

6.

If the fire burns well but sometimes smokes or burns slowly, it may be caused by the chimney top being lower than another part of the house or a nearby tree. The wind blowing over a house or a tree, falls on top of the chimney like water over a dam, beating down the smoke. The top of the chimney should be at least 3 feet above the roof and be at least 2 feet higher than any point of the roof within 10 feet

(Fig. 5).

See page 28 for list of trouble shooting tips.

A DRAFT READING OF .05 TO .06 W.C. IS SUGGESTED FOR PROPER BURNING

OF THIS UNIT WHEN USING WOOD OR BITUMINOUS COAL AS FUEL. WHEN

USING ANTHRACITE COAL, THIS DRAFT READING IS A MINIMUM READING.

Creosote and Soot - Formation and Need for Removal

When wood is burned slowly, it produces tar and other organic vapors, which combine with expelled moisture to form creosote. The creosote vapors condense in the relatively cool chimney flue of a slow-burning fire. As a result, creosote residue accumulates on the flue lining. When ignited, this creosote makes an extremely hot fire.

If soot or creosote has accumulated, it should be removed to reduce the risk of a chimney fire.

Chimney fires burn very hot. If the chimney catches fire, immediately call the fire department, then reduce the fire by closing the inlet air control. Pour a large quantity of coarse salt, baking soda or cool ashes on top of the fire in the firebox.

When coal is burned, the products of combustion combine with moisture to form a soot residue which accumulates on the flue lining. When ignited, this soot makes an extremely hot fire.

The chimney should be inspected at least twice monthly during the heating season to determine if a creosote or soot build-up has occurred.

CAUTION

A Chimney fire may cause ignition of wall studs or rafters which you thought were a safe distance from the chimney.

If you have a chimney fire, have your chimney inspected by a qualified person before using again.
