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.
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.
1. Check your local codes. The installation must comply
with their rulings.
2. Do not install this furnace in a mobile home or trailer.
3. Always connect this furnace to a chimney and vent to
the outside. Never vent to another room or inside a
building.
4. Donotconnect thisfurnacetoanaluminumTypeBgas

FireProtectionAssociationCode.Thisfurnacerequires
amasonryorListedFactoryBuiltChimneyforresidential
type or Building HeatingAppliance Chimney. Use a 6"
diameter chimney or larger, that is high enough to give
a good draft.
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.
7. Provide air for combustion into the room where the fur-
nace is located. If the intake is not in the same room,
air must have free access to the room.
8. CASTIRONPARTSMUSTBE"SEASONED"TOAVOID
CRACKING, BUILD ONLY SMALL FIRES ON FIRST
USE.
9. To prevent injury, do not allow anyone to use this fur-
nacewho isunfamiliar with thecorrectoperation ofthe
furnace.
10. For further information on using your furnace safely,
obtainacopyofthe NationalFireProtectionAssociation

ashes may be buried in the ground or picked up by a
refuse collector.
13. CAUTION- The special paints used on your furnace
may give off some smoke while they are curing dur-
ing 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
odor from registers when furnace is used for the first
time. Thisshoulddisappearafterashortperiodoftime.
Once this burn-off has occurred, it should not reoccur.
14. 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 your
furnace, use care in handling. Clean with soap and

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 HOTBLAST 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 forced draft kit that operates from a wall
thermostat. When the temperature falls below the setting
on the wall thermostat, the forced draft will come on (U.S.
Stove Option 11/DIKL)

Chimney Connection
MASONRY CHIMNEY
Before using an existing masonry chimney, clean the chimney
and inspect the flue liner to be sure it is safe to use. Make repairs
before attaching the furnace. The connector pipe and fittings you
will need to connect directly to a masonry chimney are shown.
The chimney connection should be as short as possible.
If the connector pipe must go through a combustible wall before
entering the masonry chimney, consult a qualified mason or
chimneydealer. The installationmustconform tolocal firecodes,
and N.F.P.A. 211.
DO NOT CONNECT THIS FURNACE TO A CHIMNEY
FLUE SERVING ANOTHER APPLIANCE.
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, close it tightly.
LISTED FACTORY BUILT CHIMNEY
Carefully follow chimney manufacturer's instructions. Use only a
Listed Residential Type or Building Heating Appliance Chimney.
If your chimney starts at the ceiling (Fig. 7), you will need enough
6" pipe to reach the ceiling.
The top of the chimney must 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. 7).
IMPORTANCE OF PROPER DRAFT
Draft is the force which moves air from the appliance up through
thechimney.Theamount ofdraft inyourchimneydependson the
length of the chimney, local geography, nearby obstructions and
other factors. Too much draft may cause excessive temperatures
inthe appliance.Inadequate draftmay causebackpuffing intothe
room and ‘plugging’ of the chimney.
“Inadequate draft will cause the appliance to leak smoke into the
room through appliance and chimney connector joints.”
“An uncontrollable burn or excessive temperature indicates ex-
cessive draft.”
Take into account the chimney’s location to insure it is not too
close to neighbors or in a valley which may cause unhealthy or
nuisance conditions.

1. Thecrimpedendofthechimneyconnectorfitsinsidethefurnace
flue collar. Install additional chimney connectors and elbow
with the CRIMPED END TOWARD THE FURNACE. This will
allow any condensation in the flueto run back intothefurnace.
Use 6" dia. steel pipe and elbows for connection to chimney.
Never use less than 24 gauge and although blued steel is
satisfactory, high temp painted black is much more desirable.
(See Figure 8)
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 piping and the ceiling.(See Fig. 5)
4. The chimney connector must not extend into the chimney flue.
(See Fig. 9)
5. Seal each chimney connector pipe joint with furnace cement.
Also seal the pipe at the chimney.
6. Use 3 sheet metal screws at each chimney pipe joint to make
the piping rigid.
7. Thechimneyconnector may includeasection for abarometric
draft regulator between the furnace and the chimney (Fig. 6,
7, & 10). The barometric draft regulator must be installed in
the same room (same pressure zone) as the furnace.
8. Install the barometric draft regulator strictly in accordance
withtheinstructions that areprovidedwith the barometricdraft
regulator.
9. A solid damper must be used in the chimney connecting pipes
betweenthefluecollarandthechimney. Whenusedinconjunc-
tion with a barometric draft regulator, the solid damper must be
placed between the barometric and the chimney. (See Fig. 6,
7, & 10)
ADJUSTING THE BAROMETRIC DRAFT
REGULATOR
1. Drillaholeinthechimneyconnectorwithin18"ofthefluecollar
below the barometric draft regulator just large enough for the
tube of the manometer.
2. Build a fire after all chimney connections have been made.
3. Use a manometer to measure the draft in the flue.
4. Adjust the Barometric Draft Regulator to obtain a draft of 0.05
- 0.06" W.C. under stable fire conditions.

5.A listed factory-built wall pass-through system may be
purchased and installed according to the instructions
packaged with it to provide a safe method of passing
the chimney connector through a combustible wall for
connection to a masonry chimney.
Additional requirements pertaining to Figure 8 and
the above wall pass-through systems:
1.Insulation material used as part of wall pass-through
system shall be of noncombustible material and shall
have a thermal conductivity of 1.0 Btu • in./ft.² • °F (4.88
kg • cal/hr • m² • °C) or less.
2.All clearances and thicknesses are minimums: larger
clearances and thickness are acceptable.
3.Achimney thimble, as shown for 3" and 4" above (Parts
C and D) shall be for types "3" and 4" connections to
facilitate removal of the chimney connector for cleaning.
Thechimney thimble shallbe ofASTM C315 fireclaywith

forthe propersnugfitofa 6"diameter chimneyconnector
pipe. The thimble shall be installed without damage to
the chimney flue. The thimble shall extend through the
chimney wall to, but not beyond, the inner surface of the
chimneyflue andshall bepermanently cementedin place
with high temperature cement.
4.A chimney connector to a masonry chimney, except for
2" above (Part B), shall extend through the wall pass-
through system to the inner face of the chimney flue, but
not beyond. It does not have to be fastened in place so
long as it cannot accidently be pulled out of the chimney
or shoved into the chimney flue. If fasteners are used
to secure the chimney connector to a masonry chimney,
the fasteners shall not penetrate the chimney flue liner.
5.Any material used to close up any opening for the con-
nector shall be noncombustible.
PART E - (Figure 12)
In addition to the methods shown by A, B, C, and D of
Figure 12, a listed factory-built wall pass-through sys-
tem may be purchased and installed according to the
instructions packaged with it to provide a safe method
of passing chimney connector through a combustible
wall for a connection to a masonry chimney.
If the chimney connector does not have to pass through a
combustible wall to get to a masonry chimney, simply con-
nect the chimney connector directly to the masonry chim-
ney's chimney thimble as described and shown by parts C
and D of Figure 12. Remember, the chimney connector
should extend into the chimney thimble to the innerface of
the chimney flue but not beyond; if the chimney connector
is extended through the chimney thimble into the chimney
flue,resistance tothe flowof smokeandgases upthe chim-
ney will occur; that flow resistance will have an adverse
affect on the operation and performance of the heater and
venting system.

VISIBLE SMOKE
The amount of visible smoke being produced can be an ef-
fectivemethodofdetermininghowefficientlythecombustion
process is taking place at the given settings. Visible smoke
consist of unburned fuel and moisture leaving your stove.
Learn to adjust the air settings of your specific unit to pro-
duce the smallest amount of visible smoke. Wood that has
not been seasoned properly and has a high wood moisture
content will produce excess visible smoke and burn poorly.
Use the included moisture meter to insure your wood has
a 20% or less moisture content.
EFFICIENCIES
Efficiencies can be based on either the lower heating value
(LHV) or the higher heating value (HHV) of the fuel. The
lower heating value is when water leaves the combustion
processas a vapor,in thecase ofwoodstovesthe moisture
in the wood being burned leaves the stove as a vapor. The
higher heating value is when water leaves the combustion
process completely condensed. In the case of woodstoves
thiswouldassumetheexhaustgasesareroomtemperature
when leaving the system, and therefore calculations using
this heating value consider the heat going up the chimney
as lost energy. Therefore, efficiency calculated using the
lower heating value of wood will be higher than efficiency
calculated using the higher heating value. In the United
Statesallwoodstoveefficienciesshouldbecalculatedusing
the higher heating value.
Thebestwaytoachieveoptimumefficienciesistolearnthe
burncharacteristicofyouapplianceandburnwell-seasoned
wood. Higher burn rates are not always the best heating
burn rates; after a good fire is established a lower burn rate
may be a better option for efficient heating. A lower burn
rate slows the flow of usable heat out of the home through
the chimney, and it also consumes less wood.
OVER FIRING
Attempts to achieve heat output rates that exceed heater
design specifications can result in permanent damage to
the heater.
ASH REMOVAL AND DISPOSAL
Whenever ashes get 3 to 4 inches deep in your firebox or
ash pan, and when the fire has burned down and cooled,
remove excess ashes. Leave an ash bed approximately
1 inch deep on the firebox bottom to help maintain a hot
charcoal bed.
Ashes should be placed in a metal container with a tight-
fitting lid. The closed container of ashes should be placed
on a noncombustible floor or on the ground, away from all
combustible materials, pending final disposal. The ashes
should be retained in the closed container until all cinders
have thoroughly cooled.
SMOKE AND CO MONITORS
Burning wood naturally produces smoke and carbon
monoxide(CO) emissions. CO is a poisonous gas when
exposed to elevated concentrations for extended periods
of time. While the modern combustion systems in heaters
drastically reduce the amount of CO emitted out the chim-
ney, exposure to the gases in closed or confined areas can
be dangerous. Make sure your stove gaskets and chimney
joints are in good working order and sealing properly to en-
sureunintended exposure. Itis recommended thatyouuse
both smoke and CO monitors in areas having the potential
to generate CO.
GASKETS
It is recommended that you change the door gasket (which
makes your stove door air tight) once a year, in order to in-

OPERATIONAL TIPS
Operational Tips for Good, Efficient, and Clean Com-
bustion
• Gettheappliancehotandestablishagoodcoalbed
beforeadjusting toa low burnrate (thismay take30
minutes or more depending on your wood)
• Use smaller pieces of wood during start-up and a
high burn rate to increase the stove temperature
• Be considerate of the environment and only burn
dry wood
• Burnsmall,intensefiresinsteadoflarge,slowburn-
ing fires when possible

17
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.
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.

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
are warnings that the chimney is not functioning prop-
erly. Correct the problem before using furnace. Possible
causes are:
1. The connector pipe may be pushed into the chimney
too far, stopping the draft.
2. Do not connect two furnaces or a stove and 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.
4. Ifthechimneyisoperatingtoocool,waterwillcondense
inthechimneyandrunbackintothe 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.
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 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.
6. See page 18 for list of trouble shooting tips.
CHIMNEY MAINTENANCE
Creosote and Soot - Formation and Need for Removal
When wood is burned slowly, it produces tar and other or-
ganicvapors,whichcombinewithexpelledmoisturetoform
creosote. The creosote vapors condense in the relatively
cool chimney flue of a slow-burning fire. As a result, creo-
sote residue accumulates on the flue lining. When ignited,
this creosote makes an extremely hot fire.
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
duringtheheatingseasontodetermineifacreosoteorsoot
build up has occurred.
If creosote or soot 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.
ATTENTION:
This wood heater needs periodic inspection and repair for proper operation. It is against federal
regulations to operate this wood heater in a manner inconsistent with operating instructions in this
manual.

Smoke puffs from furnace
Solution:
A. Check chimney draft. Check for blocked chimney or
flue pipe. Use mirror to check chimney clearance.
B. Check ash pit — if it is too full, empty.
C. Make sure furnace room is not too airtight.
D. Make sure all of chimney mortar connections are
airtight.
E. Check ash drawer. Make sure it’s airtight.
F. Check chimney for possible down-draft caused by
tallersurroundingtreesorobjects.Correctwithproper
chimney vent cap.
G. Check the possibility of a cold chimney forcing cool
gases backward. Remedied by properly insulating
chimneywithnon-combustibleliner—non-combus-
tible insulation.
H. Fuel may be too green.
I. Make sure no other fuel burning devices are con-
nected to the chimney impairing the draft.
J. Check chimney draft, it should be .06 inches of wa-
ter column. This service is provided by a certified
chimney sweep.
2. Problem:
Inadequate heat being delivered to your home
Solution:
A. Check home insulation — is it adequate?
B. Checkhook-up to furnace—is it installedcorrectly?
C. Cool air inlet may be inadequate or furnace room
too airtight.
D. Your wood fuel may be too low grade. Hardwoods
are recommended.
E. Make sure your hot air duct (and other duct work) is
airtight.
F. If furnace room is warm but your home isn’t, check
back draft dampers.
G. Is air to the blower available?
3. Problem:
Excesssmokeorflamescomingoutdoorwhenrefueling
Solution:
A. Wait 15 seconds and open door SLOWLY — then
refuel.
B. Checklengthoffluepipetochimney.Yourunitshould
be within six (6) feet of your chimney.
C. Make sure chimney cap is not too close to the top
of the chimney.
D. Checkchimneydraft—makesurechimneyfluepipe
is clean and chimney is of adequate height.
E. Makesureyou’re not suffocatingthe firewithexces-
sive amounts of unburned wood.
