10. Keep the ash pit section free of excess
ashes. Do not allow ashes to stack higher
than the sides of the ash pan.
11. 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.
12. 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 disap-
pear after a short period of time. Once this
burn-off has occurred, it should not reoc-
13. cur.
CARING FOR PAINTED PARTS- This
heater has a painted outside jacket, which
is durable but it will not stand rough han-
dlingorabuse.Wheninstallingyourheater,
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 scouring powder, as these
14. 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 EXTREME CON-
DITIONS THIS CAN PRODUCE DAN-
GEROUS RESULTS. AS A MINIMUM, IT
15. WILL ALLOW THE PAINT TO DIS-
COLOR.
Check local codes. The installation must
comply 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:Eitherafactorbuilt6"UL103HT

LOCATING THE HEATER
AS A LOCATION IS SELECTED,
KEEP THE FOLLOWING IN MIND:
1. The chimney connection should be as
possible. The heater must have its own chim-
ney. Do not connect this unit to a chimney flue,
serving another appliance. If there is no chim-
ney near where you wish to place the heater,
you can use a UL 103HT Residential Type and

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).

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,
andsmokechamber.Manyofthemlook
exactly like a masonry fireplace and
must be checked closely for above re-
quirements before installing a coal
heater into them.

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

unlined (should have a tile clay liner
to protect brickwork), have it relined
professionally.Clearancestocombus-
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-

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

INSTRUCTIONS FOR TWO-STEP LATCH OPERATION
1. Follow these instructions to operate you unit safely when operating the feed door.
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 damper close
and apply the same sealant you used at
the stovepipe and thimble junction.
FIREPLACE INSTALLATION
2. Turn handle clockwise to the 12 o'clock position, pull the door open until you
engage the second step (Fig. 12).
Connectionofthestovepipedirectlyinto
the existing masonry chimney over the
fireplace opening is the only approved
method. This installation performs bet-
ter, yielding easy to clean and inspect
for creosote. Before beginning this type
of installation plan carefully; a high de-
gree of skill is required to insure safety.
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. 12A)
5. To close and latch the door, reverse steps 2 thru 4.
An entry port for the stovepipe must be
cut through the chimney with minimum
damage to the fire clay liner. Some
involvedmeasurementsmayberequired
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.
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.
NOTE:
THIS NEW LATCHING MECHANISM MEETS CODES AND
PROVIDES MORE SAFETY FOR THE USER OF THIS STOVE.
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 at-
tached to an exterior wall), its mass
alone will store heat longer and con-
tinue to release the heat long after the
fire has died. Masonry chimneys have
many disadvantages though.
Keep in mind that coal mantels and
combustible 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 24" clearance
between the top of the stovepipe and
the combustible ceiling or other com-
bustibles.Placingthecenteroftheentry
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 mor-
tar. The thimble should be surrounded
on all sides with 8 inches of brickwork
(solid masonry units) or 24 inches of
stone.
Masonry chimneys constructed on an
exterior wall are exposed to cold out-
door temperatures, promoting greater
heater loss, higher accumulations of
creosote,andreduceddraftwhichleads
to poorer heater or furnace perfor-
mance.

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".
Concrete block chimneys (when not
protected by a brick veneer) are inher-
entlyunsafe,resultinpoordraft,andare
subject to rapid deterioration. They do
not meet code and are not recom-
mended.

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.
1. The connection pipe may be pushed
into the chimney too far, stopping the
draft (Fig. 8).
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
downthesmoke.Thetopofthechimney
should be at least 3 feet higher than any
point of the roof within 10 feet (Fig. 6).

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.

OPERATING INSTRUC-
TIONS
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 THE MANU-
FACTURED COAL BRICKS THAT
ARE MADE FROM COAL DUST AND
A WAX-TYPE BINDER.
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.
WARNING: THE USE OF WOOD IN
THIS STOVE EXCEPT FOR COAL IG-
NITION PURPOSES, IS A VIOLATION
OF FEDERAL LAW.
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.
NOTE: Store coal in a dry, well-venti-
lated area.
CAUTION: BUILD A FIRE ON INTE-
GRAL GRATE THAT IS PROVIDED
WITH THE HEATER.
A
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 de-
pending on model after fire is burning
briskly. Use care not to smother the
kindling fire. Set higher or lower for your
comfort.
MINIMUM FIRE
The burning rate at the low setting can
be further adjusted by opening or clos-
ing the minimum fire air shutter (Fig. 9)
on the draft control door.
1. Partiallyclosetheshuttertomakethe
fuel burn longer.
2. Open the shutter, exposing a large
opening, to reduce the formation of
creosote on soot (see notes on Chim-
ney Maintenance).
3. Do not operate the heater with the
minimum fire air shutter completely
closed.

at room temperature.
5. Set thermostat for desired tempera-
ture.
If the room temperature is not satisfac-
tory, the thermostat operating range
may be changed as follows:
A. To increase the amount of heat at a
"HIGH" setting, adjust the wire link-
age to increase the draft damper
opening (Fig. 10).
Fig. 10
NOTE: More than one recalibration
may be necessary. At room temp.
(72*F) and "Low" setting, the draft
damper door should be closed.
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.
CAUTION: DO NOT OVERFIRE THE
HEATER,ASSTATEDEARLIER,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.
1. Unhook linkage wire at point C
2. Take point A in left hand and B
right hand then turn B clockwise
about 3 turns.
3. Then hook linkage wire back to
draft control damper door at
point C.
C. Adjusting the minimum Air Shutter:
The minimum air shutter has an
infinite number of settings. Several
adjustments may be necessary for
the unit to work most effectively for
your particular installation.
1. Set thermostat to HIGH before open-
ing feed door.
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.
B. To decrease the amount of heat at
"LOW" setting:
1. The minimum air shutter may be
adjusted to the closed position in
installations where the draft is
"above normal". Generally, .06
w.c. or above would be consid-
ered "above normal".
2. In installation where the draft is
"below normal", the minimum air
shutter would be adjusted toward
the open position.
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.
1. Check feed and ash doors to be
sure that they are closed tightly.
2. Check the connector pipe to see
that it is sealed in the flue collar
and at all joints.
3. If no air leaks are found, adjust
linkage the same as above,
except turn B counterclockwise
about 3 turns.
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.
CAUTION: NEVER STORE FLAM-
MABLE LIQUIDS, ESPECIALLY
GASOLINE, IN THE VICINITY OF THE
HEATER.
