RULES FOR SAFE INSTALLATION AND OPERATION
Read these rules and the instructions carefully.
SAFETY NOTICE: If this heater is not properly installed, a house fire may result. For your
safety, follow the installation directions. Contact local building or fire officials about
restrictions and installation inspection requirements in your area.
Check local codes. The installation must com-
ply with their rulings. Do not install this heater
in a mobile home or trailer.
Always connect this heater to a chimney or
vent to the outside. Never vent to another
room or inside a building.
Do not connect a COAL burning heater to an
aluminum Type B gas vent. This is not safe
and is prohibited by all codes. This heater
requires connection to approved chimneys:
Either a factor built 6" UL 103HT or a lined and
approved and recently inspected and cleaned
masonry chimney with a 6" flue, preferably
round. A larger masonry flue may be used, so
long as the flue-section diameter is not greater
than 50 sq. in.
The chimney portion (whether factory-built or
masonry) must be tall enough to provide
sufficient draft and safe exit of smoke and
combustion products. Please refer to Page 5.
Be sure that your Chimney is safely con-
structed and in good repair. Have the chimney
inspected by the Fire Department or a quali-
fied inspector (such as a Chimney sweep).
Your insurance company may be able to
recommend a qualified inspector.
Inspect chimney connector and chimney twice
monthly during the heating season for any
deposit of creosote or soot which must be
removed.
Provide air for combustion from outside the
house into the room where the heater 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 heater who is unfamiliar with the correct
operation of the heater. Do not allow children
to use or in any way operate this heater.
For further information on using your heater
safely, obtain a copy of the National Fire
Protection Association (NFPA) publication
"Using Coal and Wood Stoves Safely" NFPA
No. HS-10-1978. The address of the NFPA
is Battery March Park, Quincy, MA. 02269.
Keep the ash pit section free of excess
ashes. Do not allow ashes to stack higher
than the sides of the ash pan.
DISPOSAL OF ASHES- Ashes should be
placed in a metal container with a tight fitting
lid. Keep the closed container on a non-
combustible 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 by a refuse
collector.
CAUTION: The special paints used on your
heater may give off some smoke while they
are curing during first few fires. Build small
fires at first. The metals used in construction
of the heater has a light coating of oil. This
could give off smoke and/or odors when
heater is used for the first couple of times.
This should disappear after a short period of
time. Once this burn-off has occurred, it
should not reoccur.
CARING FOR PAINTED PARTS- This heater
has a painted outside jacket, which is durable
but it will not stand rough handling or abuse.
When installing your heater, use care in
handling. Clean with soap and warm water
when heater is not hot. DO NOT use any
harsh chemicals (acids or caustics) or scour-
ing powder, as these wear and dull the finish.
KEEP THE FEED DOOR, ASH DOOR AND
CABINET DOOR CLOSED AT ALL TIMES
EXCEPT WHILE TENDING THE HEATER.
DO NOT OVERFIRE THE HEATER. THIS
WILL HAPPEN IF THE FEED DOOR, OR
PARTICULARLY THE ASH DOOR, IS LEFT
OPEN DURING OPERATION. UNDER EX-
TREME CONDITIONS THIS CAN PRO-
DUCE DANGEROUS RESULTS. AS A MINI-
MUM, IT WILL ALLOW THE PAINT TO
DISCOLOR.
Use coal only. DO NOT USE the coal bricks
that are manufactured from coal dust and a
wax-type binder.
CAUTION: DO NOT TOUCH THE
HEATER UNTIL IT HAS COOLED.
ALWAYS WEAR GLOVES WHEN
REFUELING THIS UNIT OR WORKING
WITH METAL CABINET PARTS.

LOCATING THE HEATER
AS A LOCATION IS SELECTED,
KEEP THE FOLLOWING IN MIND:
1. The chimney connection should be as air
tight as possible. The heater must have its own
chimney. Do not connect this unit to a chimney
flue, serving another appliance. If there is no
chimney near where you wish to place the
heater, you can use a UL 103HT Residential
Type and Building Heating Appliance Chim-
ney (Fig. 5 &6).
2. Place the heater on solid masonry or solid
concrete. When the heater is used on a com-
bustible floor protector of one layer of 3/8"
millboard having a thermal conductivity of
K=0.84 BTU in./ft. 2 hr. Deg. F with 28-gauge
sheet metal or a UL Listed floor protector. Have
the floor protector extend 16" beyond the door
side of the heater and under the connector
pipe in the back.
3. Check Figures 2, 3, and 4. Be sure you have
the clearances shown from the heater and the
connector pipe to combustible surfaces. If you
have a solid brick or stone wall behind your
heater, you can place the heater as close as
you wish to the wall. If the wall is only faced with
brick or stone, treat it as a combustible wall.
NOTE: BEFORE FIRING
HEATER
Slide firebricks toward the rear
so no gaps remain between
them.
CAUTION:
Keep furnishings and other
combustible materials away
from the heater.

CHIMNEY CONNECTION
Two basic types of chimneys are approved for use with solid fuel: Factory-built and
masonry. Factory-built chimney must comply with UL103HT standard.
Do not expect your stove or furnace to create draft. Draft is not a function of the
appliance. Draft is purely a function of the chimney. Modern stoves and furnaces
are much more airtight and efficient than those of the past; and, therefore require
greater draft. A minimum of .05, measured in water column (gauges to measure
chimney draft are readily available at stove shops and are economical to purchase
or rent) is required for proper drafting to prevent back-puffing, smoke spillage, and
to maximize performance.
Chimneys perform two functions - one of which is apparent: The chimney provides
a means for exhausting smoke and flue gases resulting from combustion of the fuel.
Secondarily, though, the chimney provides "Draft" which allows oxygen to be
continuously introduced into the appliance, so that proper combustion is possible.
As of April 1, 1987, all heaters and furnaces manufactured by United States Stove
Company should be installed using a factory built chimney that meets the "Type HT"
requirement of UL 103 (when a factory - built chimney is used).
IMPORTANT
*Size the chimney to the flue outlet on the stove. (6" outlet = 6" I.D. chimney)
*Avoid using elbows except as necessary (they reduce draft).
*Make sure all horizontal runs of connector pipe go up hill (1/4" elevation for each
horizontal foot).

INSTALLATION OF A COAL

615
Many people may wish to convert an
existing fireplace to heater use. Usually,
safe connection of stovepipe to a ma-
sonry chimney requires more effort than
connection to a prefabricated chimney.
The fireplace must be closed and sealed
at the damper in the flue. Good sealants
are high temperature caulking, ceramic
wool, and furnace cement. Always re-
member to inspect the masonry chim-
ney and fireplace. If necessary, clean
the flue and smoke shelf before begin-
ning your installation. Install the heater
into the chimney so that the system can
be dismantled for cleaning and inspec-
tion.
Before deciding to convert your fire-
place or existing chimney, keep in mind
that older fireplaces and their chimneys
are unsafe. They must be structurally
sound, and the flue liner must be in good
condition. Do not use a chimney if it is
unlined (should have a tile clay liner
to protect brickwork), have it relined
professionally. Clearances to combus-
tibles are explained in the previous sec-
tion on masonry chimneys. If you have
any questions regarding the condition
of the chimney, consult a qualified engi-
neer, competent mason, certified Chim-
ney Sweep, or knowledgeable inspec-
tor.
Many prefabricated fireplaces fall into
the "zero-clearance fireplace" category.
This is a factory metal fireplace with
multilayered construction. It is designed
to provide enough insulation and/or air
cooling so that the base, back and sides
can be safely placed in direct contact
with combustible floors and walls. Al-
though many prefabricated fireplaces
have been tested by nationally recog-
nized organizations for use as fire-
places, they have not been tested to
accept heaters. In fact, their use as such
may void the manufacturer's warranty.
Steel-lined fireplaces, on the other
hand, can be used with heaters. These
units use a 1/4-inch fire box liner and an
air chamber in connection with 8 inches
of masonry to meet code. They contain
all the essential parts of a fireplace,
firebox, damper, throat, smoke shelf,
and smoke chamber. Many of them look
exactly like a masonry fireplace and
must be checked closely for above re-
quirements before installing a coal
heater into them.
Another method frequently used by
some people is to vent the heater di-
rectly into the fireplace. This does not
meet code since the heater is being
vented into another appliance - the
fireplace. This method should not be
attempted because combustion prod-
ucts will deposit and build up in the
firebox or fireplace. Be certain not to
install a hazard in you house. You will
void your warranty with this installa-
tion.

FIREPLACE INSTALLATION
Connection of the stovepipe directly
into the existing masonry chimney over
the fireplace opening is the only ap-
proved method. This installation per-
forms better, yielding easy to clean and
inspect for creosote. Before beginning
this type of installation plan carefully; a
high degree of skill is required to insure
safety.
An entry port for the stovepipe must be
cut through the chimney with minimum
damage to the fire clay liner. Some
involved measurements may be re-
quired to locate the flue liner exactly.
Before cutting, take time to mark the size
and position of the entry port. Position
the entry port so that at least 8 inches of
the flue liner remains below the port.
Keep in mind that mantels and combus-
tible trim around the fireplace must have
adequate clearances from the heater
and stovepipe or must be protected in
an approved manner. Also, be sure to
leave at least 18" clearance between
the top of the stovepipe and the com-
bustible ceiling or other combustibles.
Placing the center of the entry port 2 feet
below the ceiling will insure proper
clearance for 6 inch, 8 inch, and 10 inch
stovepipes. Next, install a fire clay (at
least 5/8 in. thick) or metal thimble,
being sure that the thimble is flush with
the inner flue lining, secure the thimble
in place with refractory mortar. The
thimble should be surrounded on all
sides with 8 inches of brickwork (solid
masonry units) or 24 inches of stone.

INSTRUCTIONS FOR TWO-STEP LATCH OPERATION
1. Follow these instructions to operate you unit safely when operating the feed door.
2. Turn handle clockwise to the 12 o'clock position, pull the door open until you
engage the second step (Fig. 11).
3. Hold the door in that position for approximately 10 seconds.
4. Then to open door, turn the handle counter clockwise to the 9 o'clock position
and then continue to pull the door open. (Fig. 11A)
5. To close and latch the door, reverse steps 2 thru 4.
NOTE:
THIS NEW LATCHING MECHANISM MEETS CODES AND
PROVIDES MORE SAFETY FOR THE USER OF THIS STOVE.
14
NOTE:
DURING OPENING AND CLOSING OF THE FEED AND ASH DOORS
OF THIS HEATER, IT MAY SEEM THAT THE FIT OF THE DOOR IS
"TOO TIGHT". AS THE HEATER IS FIRED, THE GASKETING
"SETTLES" OR "SEATS" ITSELF IN THE DOOR. THE TIGHT FIT AT
THE FACTORY AND BEFORE THE HEATER'S INITIAL FIRING IS TO
INSURE A GOOD SEAL AFTER THE GASKETING "SETTLES".
Install the stovepipe as far as possible
into the thimble, but not past the inside
of the flue lining. There should be a
small airspace (approximately 1/2 inch)
between the stovepipe and thimble,
allowing for expansion of the stove-
pipe. Seal this airspace with high-tem-
perature caulking or ceramic wool. Fi-
nally, be sure to wire the fireplace
damper close and apply the same seal-
ant you used at the stovepipe and
thimble junction.
Do not use the Type B installation (not
illustrated in this manual), that is, vent-
ing up through the fireplace opening,
regardless of whether the fireplace
opening is closed.
Masonry chimneys have several posi-
tive attributes: If properly built, they are
quite durable, and most homeowners
consider them more attractive perhaps
than a non-enclosed factory built chim-
ney. And, if the chimney is located
within the confines of the house (that is,
not attached to an exterior wall), its
mass alone will store heat longer and
continue to release the heat long after
the fire has died. Masonry chimneys
have many disadvantages though.
Masonry chimneys constructed on an
exterior wall are exposed to cold out-
door temperatures, promoting greater
heater loss, higher accumulations of
creosote, and reduced draft which leads
to reduced heater or furnace perfor-
mance.
Concrete block chimneys (when not
protected by a brick veneer) are inher-
ently unsafe, result in poor draft, and are
subject to rapid deterioration. They do
not meet code and are not recom-
mended.
Fig. 11 Fig. 11A

SERVICE HINTS
Do not expect a heater 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 are warnings that the chimney
is not functioning properly. Possible
causes are:
1. The connection pipe may be pushed
into the chimney too far, stopping the
draft (Fig. 8).
2. Do not connect two heaters into the
same chimney flue.
3. The chimney used for a heater 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.
4. If the chimney is too cool, water will
condense in the chimney and run back
into the stove. Creosote formation will
be rapid and may block the chimney.
Operate the heater 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 another part of the house or a
nearby tree. The wind blowing over a
house or a tree falls on top of the chim-
ney like water over a dam, beating
down the smoke. The top of the chimney
should be at least 3 feet higher than any
point of the roof within 10 feet (Fig. 6).
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 connector should be in-
spected at least twice monthly during
the heating season to determine if a
creosote buildup has occurred.
If creosote has accumulated, it should
be removed. Failure to remove creo-
sote or soot may cause a house fire.
Creosote may be removed by using a
chimney brush or other commonly avail-
able materials.
Chimney fires burn very hot -- up to
2100 degrees F. If you experience a
chimney fire, immediately call the fire
department. They have the professional
means for extinguishing a chimney fire.
Once a chimney fire has occurred, it can
only be extinguished by removing its
sources of oxygen. This can be accom-
plished by shutting any mechanical draft
device such as dampers, discharging a
CO2 (carbon dioxide) or halon fire ex-
tinguisher directly into the stove through
an appropriately placed cleanout. If us-
ing a Halon extinguisher, please re-
member that is totally displaces oxygen
and could become a hazard in itself if
enough were discharged into a living
space.
NOTE:
A draft reading of .05 to .06 w.c. is suggested for proper burning of this unit
when using bituminous coal as fuel. When using anthracite coal, this draft
readings is a minimum reading.
CHIMNEY MAINTENANCE
CREOSOTE-FORMATION AND NEED FOR REMOVAL
138
Most masonry chimneys have a cleanout. If yours does, make sure it is gasketed or
otherwise sealed. A loose fitting door will contribute greatly to the draft problems.
If you have any question regarding venting your appliance, feel free to contact the
factory at the address and phone number on this Owner's Manual. You may also
contact NFPA (National Fire Protection Association) and request NFPA Standard
211 (1984 Edition). Their address is Battery March Park, Quincy, Massachusetts
02269. Another helpful publication is NFPA Standard 908, available at the same
address. Specify 1984 Edition on either of the above publications.

SUGGESTIONS FOR BURNING ANTHRACITE COAL
1. With coal it is important to maintain a clean chimney. The chimney connector and
chimney should be inspected at least twice monthly during heating season.
2. Keep the grate clear of ash and cinders. Use the shaker grate to keep the ashes from
building up in the firebox.
3. Do not operate the unit with the ash door, feed door, or cabinet door open.
4. Anthracite coal burns with a short, blue flame with the coals having a glowing, red color.
Before adding coal, when starting the fire, have a good hot log fire burning.
5. After having a log fire burning, add small amounts of coal until a bed of coal is built up.
6. A draft reading of -.05 to -.06 in w.c. is required for anthracite to burn.
The draft wheel located on the feed door should be opened when burning coal. The
draft wheel provides a source of secondary air that is needed when burning coal.
Secondary air is needed because when coal burns, it gives off large quantities of
volatile gases that need additional air before complete combustion can occur. This
draft wheel may be adjusted to give the best performance depending on the
particular needs of the user.
RULES FOR CONNECTOR PIPE INSTALLATION
1. The crimped end of the stovepipe fits
inside the heater flue collar. Install addi-
tional pipe and elbow with the CRIMPED
END TOWARD THE HEATER. This will
allow any condensation in the flue to run
back into the heater.
2. Slope any horizontal pipe upward
toward the chimney at least 1/4 inch for
each foot of horizontal run.
3. You must have at least 18 inches of
clearance between any horizontal pip-
ing and the ceiling.
4. The pipe cannot extend into the
chimney flue. (Fig. 8)
5. Seal each connector pipe joint with
furnace cement. Also seal the pipe at
the chimney.
6. Use 3 Sheet Metal screws at each
joint to make the piping rigid.
7. It is recommended that no more than
two 90 degree bends be used in the
stovepipe installation. More than two
may decrease the amount of draw. Use
only corrugated (non-adjustable) el-
bows as they are much more airtight.
8. The chimney connector must not
pass through an attic, roof space, closet,
any concealed space, floor, ceiling, wall
or combustible construction.

OPERATING INSTRUCTIONS
FUEL
Egg size Bituminous coal for residential
furnaces, or any of the specially pack-
aged fireplaces coals can be used. Coal
with a low ash content (2% to 6%) is
recommended.
NOTE: Store coal in a dry, well-venti-
lated area.
LIGHTING
1. Set the thermostat on "High" for
maximum draft.
2. Open the feed door and place paper
and kindling on the grate for starting the
fire.
3. Light fire and close feed door.
4. Add about 15 pounds of coal depend-
ing on model after fire is burning briskly.
Use care not to smother the kindling fire.
5. Set thermostat higher or lower for
your desired temperature.
ADDING FUEL
When starting a fire, add small amounts
of fuel periodically as required (enough
to burn for 3 to 5 hours). As you become
more familiar with the operation of your
heater, it is possible to add coal to burn
for longer durations of between 8 to 12
hours, but doing so carelessly will pro-
mote incomplete combustion and con-
siderable sitting, along with a very dirty
inefficient fire.
1. Set thermostat to HIGH before open-
ing feed door.
2. Coal Fire- Never smother the fire
when adding coal. Gas accumulation
and a mild smoky explosion will occur:
a. Add fresh kindling if the bed of
coals has cooled.
b. Add up to 20 lbs. of coal. Never
add coal above top of the firebrick.
c. Stir the coal and watch the fire.
Be sure the new coal is burning
before you close the doors and turn
the thermostat down.
3. Shake Grates vigorously back and
forth to dump ashes into ash pan. Do
this at least once every 12 hours of
operation.
4. Empty ash pan regularly. Do not
allow ashes to build up to grate, as grate
will warp and burn out, and you might
spill the ashes when removing the pan.
Dispose of hot ashes properly. (See
note 12 on page 3)
CAUTION: BUILD A FIRE ON INTE-
GRAL GRATE THAT IS PROVIDED
WITH THE HEATER.
CAUTION: DO NOT OVERFIRE THE
HEATER, AS STATED EARLIER, THIS
CAN PRODUCE A DANGEROUS
CONDITION AND EVEN CAUSE A
HOUSE FIRE. IF ANY PORTION OF
THE HEATER OR ANY CHIMNEY
CONNECTOR GLOWS RED OR DIS-
COLORS, THE HEATER IS BEING
OVERFIRED.
CAUTION: DO NOT OPERATE THIS
HEATER WITH FEED OR ASH DOOR
OPEN. THIS HEATER IS DESIGNED
FOR THERMOSTATIC OPERATION.
OPERATION WITH EITHER DOOR
OPEN WILL OVERHEAT AND DAM-
AGE THE HEATER.
CAUTION: NEVER STORE FLAM-
MABLE LIQUIDS, ESPECIALLY
GASOLINE, IN THE VICINITY OF THE
HEATER.
CAUTION: NEVER USE THE MANU-
FACTURED COAL BRICKS THAT
ARE MADE FROM COAL DUST AND
A WAX-TYPE BINDER.
WARNING: THE USE OF WOOD IN
THIS STOVE EXCEPT FOR COAL IG-
NITION PURPOSES, IS A VIOLATION
OF FEDERAL LAW.
CAUTION: GASES THAT ARE
DRIVEN FROM FRESH COAL MUST
BE BURNED OR THEY WILL ACCU-
MULATE AND EXPLODE. NEVER
SMOTHER A FIRE WHEN ADDING
FRESH COAL.
CAUTION: NEVER USE GASOLINE,
GASOLINE-TYPE LANTERN FUEL,
KEROSENE, CHARCOAL LIGHTER
FLUID, OR SIMILAR LIQUIDS TO
START OR "FRESHEN UP" A FIRE IN
THE HEATER.
