1. The chimney connection should be as airtight as possible. The heater must have its own
chimney flue. 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 Chimney (Fig. 5, 6, 6A & 6B).
2. Place the heater on solid masonry or solid concrete. When the heater is used on a
combustible 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
thefloor protector extend 16" beyondthe door side of theheater and under the connectorpipe
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.

of which is apparent: The chimney
providesameansforexhaustingsmoke
andfluegasesresultingfromcombustion
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
"TypeHT"requirementofUL103(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 con-
nector pipe go up hill (1/4" elevation for
each horizontal foot).
CHIMNEY CONNECTION
Two basic types of chimneys are ap-
proved for use with solid fuel: Factory-
builtandmasonry.Factory-builtchimney
must comply with UL103HT standard.
Do not expect your stove or furnace to
createdraft.Draftisnotafunctionofthe
appliance. Draft is purely a function of
the chimney. Modern stoves and
furnaces are much more air-tight and
efficient than those of the past and,
therefore require greater draft. A
minimum of .05, measured in water

CAUTION:
NOT ALL FIREPLACES
ARE SUITABLE FOR
INSTALLATION OF A WOOD
HEATER.
Many people may wish to convert an
existingfireplacetoheateruse.Usually,
safe connection of stovepipe to a ma-
sonrychimneyrequiresmoreeffortthan
connection to a prefabricated chimney.
Thefireplacemustbeclosedandsealed
atthedamperintheflue.Goodsealants
arehigh 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
intothechimneyso that the system can
be dismantled for cleaning and inspec-
tion.
Before deciding to convert your fire-
placeor existing chimney, keepinmind
thatolderfireplaces and their chimneys
are unsafe. They must be structurally
sound,andthefluelinermustbeingood
condition.Donotuse achimney if itis
unlined (should have a tile clay liner
to protect brickwork), have it relined
professionally.Clearancestocombus-
tiblesare explainedintheprevious sec-
tion on masonry chimneys. If you have
any questions regarding the condition
ofthe chimney,consultaqualified engi-
neer,competentmason,certifiedChim-
ney Sweep, or knowledgeable inspec-
tor.
Many prefabricated fireplaces fall into
the"zero-clearancefireplace"category.
This is a factory metal fireplace with
multi-layeredconstruction.Itisdesigned
to provide enough insulation and/or air
coolingsothatthebase,backandsides
can be safely placed in close 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
acceptheaters.Infact,theiruseassuch
may void the manufacturer's warranty.
Steel-lined fireplaces, on the other
hand, can be used with heaters. These
unitsuse a 1/4-inchfireboxlinerand an
airchamberinconnectionwith8inches
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.
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.

Install the stovepipe as far as possible
into the thimble, but not past the inside
of the flue lining. There should be a
small air space (approximately 1/2 in.)
between the stovepipe and thimble, al-
lowing for expansion of the stovepipe.
Seal this airspace with high-tempera-
ture caulking or ceramic wool. Finally,
be sure to wire the damper closed and
apply the same sealant you used at the
stovepipe and thimble junction.
Do not vent up through the fireplace
opening,regardlessof whether the fire-
place opening is closed.
MASONRY CHIMNEY have several
positiveattributes: If properly built, they
arequitedurable,andmosthomeowners
consider them more attractive perhaps
than a non-enclosed factory built
chimney. And,ifthechimney is located
withintheconfinesof 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,andreduceddraftwhichleads
topoorerheaterorfurnaceperformance.
FIREPLACE INSTALLATION
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
forcreosote.Before beginning this type
of installation plan carefully; a high de-
gree 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
involvedmeasurementsmayberequired
to locate the flue liner exactly. Before
cutting, take time to mark the size and
position of the entry port. Position the
entryport so that at least 8 inches ofthe
flue liner remains below the port.
Keep in mind that wood mantels and
combustible trim around the fireplace
must have adequate clearances from
the heater and stovepipe or must be
protectedinanapprovedmanner.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
thethimbleinplacewithrefractorymor-
tar. The thimble should be surrounded
on all sides with 8 inches of brickwork
(solid masonry units) or 24 inches of
stone.
CAUTION
A chimney fire may cause ignition of wall studs or rafters which you
thought were safe distance from the chimney. If you have a chimney fire,
have your chimney inspected by a qualified person before using again.
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
chimneyare warnings that the chimney
is not functioning properly. Possible
causes are:
1. Theconnection pipe maybepushed
into the chimney too far, stopping the
draft (Fig. 8).
2. Two heaters connected into the
same chimney flue.
3. Samefluebeingusedtoventilatethe
cellarorbasement.Ifthereisacleanout
opening at the base of the chimney, it
must be closed tightly and sealed.
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.
Operatetheheateratahighenoughfire
to keep the chimney warm preventing
this condensation. (Poorly insulated
chimney)
5. The chimney top may be 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 higher than any point
of the roof within 10 feet (Fig. 6).
6. Other chimney/flue inadequacies
covered else where in this manual.
If creosote has accumulated, it should
be removed.
Failure to remove creosote or soot may
cause a house fire. Creosote may be
removed by using a chimney brush or
othercommonlyavailablematerials. Or,
betteryet,byacertifiedchimneysweep.

CHIMNEY MAINTENANCE
CREOSOTE-FORMATION AND NEED FOR REMOVAL
NOTE:
A draft reading of .05 to .06 w.c. is suggested for proper burning of this
unit.
SERVICE HINTS
13
When wood is burned slowly, it pro-
duces tar and other organic vapors,
which combine with expelled moisture
to form creosote. The creosote vapors
condenseinthe 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.
The chimney connector and chimney
should be inspected at least twice
monthly during the heating season to
determine if a creosote build-up has
occurred.

9
When considering a masonry chimney,
round tiles are preferable to square or
rectangular, as round tiles have much
better airflow characteristics and are far
easier to clean. Unfortunately, most
North American chimneys use square or
rectangular tile liners that are really de-
signed for open fireplaces, not stoves or
furnaces. Of most importance, second
only to overall chimney height, is the
diameter of the flue liner itself. In most
instances, it should be sized to the appli-
ance; i.e., 6" flue outlet on the appliance
requires a 6" flue. The inner diameter
should never be less than the flue outlet
diameter and should never be greater
than50%oftheappliance flueoutlet.For
example, do not expect a wood burning
stove or furnace to function properly if
installed into a chimney with a flue liner
greater than 50% the appliance outlet -
- such as a 6" flue outlet requires a 6"
diameter for optimum drafting, but can
function well with an 8", but becomes
borderline beyond 8" diameter.
Masonry chimneys built of concrete
blocks without flue liners of at least 5/8"
fireclay do not meet modern building
codes. A

ADDING FUEL
When possible, add small amounts of
fuel each hour or so instead of adding
large quantities of fresh fuel every 4 to
5 hours. This will give more complete
combustion and less build-up of tars or
soot in the chimney.

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

the chimney.
6. Use 3 Sheet Metal screws at each
joint to make the piping rigid.
7. Itis recommended thatnomorethan
