rules for safe installation and operation
Read these rules and the instructions carefully. Failure to follow them will cause a hazard that could result in
death, serious bodily injury, and/or property damage.
1.
2.
3.
Check your local codes. This installation must comply with their rulings.
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.
4.
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)
5.
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.
6.
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.)
7.
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.
8.
CAST IRON PARTS MUST BE "SEASONED" TO AVOID CRACKING. BUILD ONLY SMALL FIRES
ON FIRST USE.
9.
To prevent injury, do not allow anyone to use this furnace who is unfamiliar with the correct operation
of the furnace.
10.
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.
11.
12.
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.
13.
14.
15.
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.
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
the blower on the central system also comes on.
The blower will only come on when the tempera-
ture 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 supplemen-
tary 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 installa-
tion uses only the blowers of the existing central
furnace. The solid fuel fan/limit control must
also control the functions of the existing fur-
nace. All electrical power must come from a
single branch circuit (see Fig. 15).
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
standardsandequippedwiththerequired
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 thor-
oughly 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'sinstallationinstructionsfurnished
with the solid fuel furnace.
The chimney connector of the furnace is to
be installed to provide clearances to combus-
tible 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,
CENTRAL FURNACE INSTALLATION: As a
central furnace, the unit functions independently
of any other system. The blower will come on

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
heatingequipmentinstaller.
2. The installation is to be done in compliance
withNationalFireProtectionAssociationinstalla-
tion 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
intochimneywithotherfuelburningappliances.)
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" deter-
mine that air is of adequate makeup. (Reference
N.F.P.A. Nos. 30 & 54, Code for Installation of
Gas & Oil Equipment)

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
perhapsthebestcoalfuelbecauseitslongevenburntime, highheatoutput, andcleanlinessmakeitagoodchoice
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"coaltosmall"egg"coal(1-3/4"diameterto4"diameter). WhenburningAnthracite,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
thecoal. Thebestignitionfiresutilizedrypineorotherresinoussoftwoodsaskindling,withhardwood(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, shouldbefiredwiththe"conicalmethod"-withthehighestportionofyourfirebedinthecenterofthefirebox.
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.
OncethefireisWELLESTABLISHEDaddcoaltothecenterofthefireboxformingthecone. Burninginthisfashion
allows heat to drive off the volatile gases, and turbulence created increases the burn efficiency. There will have to

areproperlyburned. Beforerefueling,takethetimetobreakuptheconealittlewithapoker,especiallyifithascaked
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

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

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,avoidshaking,asaheavierlayerofashwillhelpreducetheintensityofthefireduringthistime. Afterloading
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

ADJUSTING BLOWER LIMIT
CONTROL SETTINGS
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)
BLOWER FAN
"OFF" POINTER
1. Move both pointers towards the right (counter clock-
wise) - this increases the temperature setting at which
the blower will turn on and off.
2. Move both pointers towards the left (clockwise) - this

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

service hints
Do not expect a furnace to draw. It is the chimney that
creates the draft. Smoke spillage into the house or exces-
sive 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 forma-
tion will be rapid and may block the chimney. Operate the
furnace at a high enough fire to keep the chimney warm
preventing this condensation.
5. If the fire burns well but sometimes smokes or burns slowly,
it may be caused by the chimney top being lower than
anotherpartofthehouseoranearbytree. Thewindblowing
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).
1. The connector pipe may be pushed into the chimney
too far, stopping the draft (Fig. 6).
2. Do not connect two furnaces or a stove and a furnace
into the same chimney flue.
3. 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. 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 If soot or creosote has accumulated, it should be removed to

tively cool chimney flue of a slow-burning fire. As a result, Chimney fires burn very hot. If the chimney catches fire, imme-

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