INTRODUCTION
Thank you for purchasing a Cumberland Stove Works Multi
Fuel Parlor Stove from Ardisam, Inc. We have worked to
ensure that the multi fuel burning stove meets high standards for usability and durability. With proper care, your
stove will provide many years of service. Please read this
entire manual before installation and use. Congratulations
on your investment in quality.
BURNING SOLID FUELS
Ashes need to be removed from the stove periodically.
See Normal Care & Maintenance section for cleaning
procedure.
The parlor stove, due to the nature of solid fuels, will require
brief periodic attention. A few moments of adjustment and
cleaning from time to time is an important part of burning
solid fuels, due to the vast differences in fuel, humidity and
outside temperature.
The parlor stove has been designed to burn dry shelled
corn, pelletized fuel such as wood pellets and sunflower
pellets that meet Association of Pellet Fuel Industries
(A.P.F.I.) standards.
There are two pellet types currently approved for the
Cumberland Stove. They are dried corn and pelletized
wood. These two types are divided into three pellet type
selections. They are corn seed and press wood and Natural
Wood. The feed rates (auger ON/OFF) for each of these
three selections are programmed in 0.001 second (1ms)
intervals. The fuel map uses a set of equations that allow
pellets to fall into the burn pot and be consumed by the fire
at a 99% burning efficiency. The general guideline for pot
loading is: The auger increases the pot fill in a nonlinear
relationship to the pot consume number. This indirect
relationship uses a set of heat transfer equations to vary
this rate from 7.01 to 23.60 grams every cycle.

REQUIRED FOR LIGHTING AND ASH REMOVAL.
CAUTION
BURNING ONLY THE RECOMMENDED 11-14% MOISTURE
CONTENT CORN WILL ASSURE LONGER STOVE LIFE
AND LESS FREQUENT CLEANING.
BURNING WO O D PEL L E T S AC C O R D I N G TO
RECOMMENDATIONS WILL ASSURE LONGER STOVE
LIFE AND LESS FREQUENT CLEANING.
THE USE OF GRATES OR OTHER METHODS OF
SUPPORTING THE FUEL IS NOT AUTHORIZED IN THIS
PARLOR STOVE.
SHELLED CORN
Dry, shelled corn, preferably with 11-14% moisture
content.
• Corn should contain less than 14% moisture content.
Wet corn will rapidly deteriorate stove components,
reduce efficiency and void all warranties. Purchase a
moisture tester if in doubt.
• Corn must be clean and free from debris. Never burn
corn right from the field. Damage caused by dirty corn
is not covered by the product warranty. Ask for clean
filtered corn only. Stalk parts, excessive fines and cob
remnants will clog the auger. Check the corn for foreign
objects.
• Store the corn supply in a dry place and keep bags or
container sealed to prevent it from absorbing excess
Page 6 800-345-6007
CumberlandStoveWorks.com
Page 9
moisture. Test the moisture content periodically to
ensure the proper dryness.
• There are many varieties of corn grown around the
world. Each variety has unique characteristics including
the shape and size of the kernel. The stove will burn
more consistently with a small to midsize kernel corn. If
the kernel size of the corn varies greatly or if you switch
sources frequently, you will get a less consistent burn.
Therefore, purchasing corn from the same source will
help achieve a more consistent burn.
WOOD PELLETS
• As with corn, find a consistent pellet supplier. Pellets will
vary in content and burn characteristics from supplier
to supplier. A consistent supply of pellets will result in a
more consistent and efficient burn.
• Check the pellets for foreign objects. The stove warranty
will not cover damage done to the stove due to foreign
objects in the fuel supply.
• Store the pellets in a dry place to prevent them from
absorbing added moisture.
• To decrease sawdust buildup, the hopper will need to
be vacuumed out after every 6-8 bags of wood pellets
or more often if the pellets are poor quality. You may
have to screen each bag of pellets if sawdust becomes
a problem.
• The press wood pellet is generally produced out of
wood waste such as sawdust and shavings. The raw
material is dried, mechanically fractioned to size and
extruded under intense pressure into pellets. In the
process the raw material is compressed approximately
3.7 times. High quality wood pellets have a moisture
content of 3 to 7% and are hydrophilic. The shiny surface
of the pellet is caused by partial plasticizing of the lignin
in the wood due to high pressure and the evaporation
of the water soluble compounds during the production
process. The surface protects the pellets from absorbing
any significant amount of airborne water vapor under
normal atmospheric conditions. However, wood pellets
need to be protected from direct water penetration. If
exposed to water droplets, from condensation, they will
gradually decompose and loose their effectiveness as
a fuel. The decomposition involves expanded volume
and over time a gradual chemical breakdown.
• The natural wood pellet is the woody remains of
cherries, edible nuts and any other locally used woody
plant that has been classified by the pellet distributor
as “natural wood.” It should be comparable in size to
the press wood pellets which are 1/4 inch to 5/16 inch
diameter and about 3/4 inches long. The natural wood
pellet should contain less than 10% moisture.

combustible construction is desired, the installation
shall conform to CAN/CSA -8365.
TYPE OF VENT
Pellet venting pipe (also known as L vent) is constructed
of two layers with air space between the layers. This air
space acts as an insulator and reduces outside surface
temperature of pipe to allow a clearance to combustibles
of only 3”.
A UL listed 3” or 4” type L pellet vent exhaust system must
be used for installation and attached to the pipe connector
provided on the back of the stove. Use a 3” to 4” adapter
for 4” pipe. A cap must be used at the termination of type
L vent chimneys. For elevations above 2,500 feet above
sea level, a 4” L is required.
PELLET VENT INSTALLATION
Termination must exhaust above air inlet elevation.
Installation MUST include three vertical feet of pellet vent
pipe.
This will create some natural draft to prevent the possibility
of smoke or odor during appliance shutdown and to keep
exhaust from causing a nuisance or hazard from exposing
people or shrubs to high temperatures.
The installation must include a clean out tee to enable
collection of fly ash and to permit periodic cleaning of the
exhaust system. 90º elbows accumulate fly ash and soot
thereby reducing exhaust flow and performance of the
stove. Each elbow or tee reduces draft potential by 30% to
50%. Use no more than 180º of elbows (two 90º elbows,
or two 45º and one 90º elbow, etc.) to maintain adequate
draft.
Total length of horizontal vent must not exceed 10 feet. The
maximum recommended vertical venting height is 12 feet
for 3” type L vent. All joints for connector pipe are required
to be fastened with at least three screws and all pellet vent
connections must be sealed according to manufacturer’s
recommendations.
The area where the vent pipe goes through to the exterior
of the home must be sealed with silicone or other means
to maintain the vapor barrier between the exterior and the
interior of the home.

UNDERSTANDING THE TRI-X CONTROLLER
The controller is located on the lower right-hand side of
the parlor stove. It uses an advanced microprocessor that
allows the owner to burn multiple fuels with the touch of a
key. The TRI-X screen will display, for the user, a sequence
of stove functions and any faults that may occur during
operation. Each key functions with a small light (LED) that
indicates stove heat transitions and running status.
ON KEY
Pressing the ON key will begin the startup sequence for
the stove. Fuel will feed through the auger feed system
after a brief exhaust check. This check assures the burn
area is sealed and the flue gases are exiting the building.
The draft fan (exhaust) will start as soon as the ON key is
pressed. The fan will automatically adjust speed to match
the heat requirement. The circulating blower will turn on
when the stove heat level has reached 110°F. When this
temperature is reached, the dial to the right of the TRI-X
controller is used to adjust room blower fan speed. The
TRI-X screen shows the stove progress and will come to
rest on [STOVE CONTROLLED BY TEMP KEY {heat level
1 thru 6}] when the stove is heating normally.
The LED light will illuminate when the ON key is pushed
and remains on during normal operation.

LIGHTING THE STOVE
Before lighting the stove for the first time, make sure that
no shipping items have been left inside the ash pan, the
storage hopper, or inside the glass door fire box. The parlor
stove is now ready for operation. The sound you may
hear when beginning the start sequence is the exhaust
fan starting as soon as the ON key is pushed. It is normal
to see a small amount of smoke inside the stove during
the start cycle. If you see smoke in the room during this
starting time there is an unacceptable leak.
LIGHTING PROCEDURE:
• Plug the parlor stove into a standard household wall
receptacle. The TRI-X controller will light up and display
a sequence of power up messages.
• Fill the hopper with approved solid fuel.
• The first screen that you will see after the controller
completes the power up is [SELECT FUEL TYPE USE
MODE KEY].
• Press the MODE key until the desired fuel is displayed
on the screen.
• Pressing the AUX 1 key accepts the fuel type displayed.
After the AUX 1 key is pressed the screen will read
[LIGHT FIRE AND THE PUSH THE ON KEY].
• Fill the fire pot with about one cup of starting pellets or
wood pellets. If wood pellets are used, squirt about two
tablespoons of burn gel on the pellets.
Note: Cumberland Stove Works only approves burn
gel and starter pellets when lighting the parlor
stove.
• Light the material in the fire pot, close the door and push
the ON key.
• The screen will read [STARTUP CHECK EXHAUST
OFF] for a minimum of 15 seconds. If the doors are
sealed properly the message will change to [STARTUP
CHECK EXHAUST RUNNING]. When this message is
displayed it means the stove is in proper working order,
all of the doors are sealed and the flue gas is exiting. At
this time, the controller will begin the startup sequence.
The TEMP UP and TEMP DOWN keys can be pressed
to select level one through six (1-6). The level selected
during the startup sequence will be the level the stove
goes to after the startup sequence.
Note: If the hopper is empty when the stove is
started, the feed auger must be primed. Press and
hold the ADD FUEL key until fuel is seen dropping
into the fire pot. During the startup sequence fuel
can be manually fed into the pot by pressing the
ADD FUEL key at any time.

NORMAL CARE & MAINTENANCE
CLEANING THE GLASS
When the fire is first started, it will produce some smoke.
The smoke might accumulate on the glass surface. Before
the fire gets hot, open the door and wipe the glass surface
off with a damp rag.
If after constant use, the glass might fill with ash deposits.
You must clean the glass after the glass has cooled down.
Do not touch the surface with your hands. Take a damp rag
and wipe the glass clean. If this does not clean the glass
use any non-abrasive liquid spray.
REMOVAL OF CERAMIC GLASS
Open the door and lift off of hinges. If the door is tight, tap
gently on the bottom of the door with your hand or rubber
hammer. Lay door down on newspaper with glass clips
facing you. Loosen the screws and take off the glass clips.
Remove the broken glass carefully and discard.
Reverse the above procedure for replacing new glass with
new gasket.
FUEL POT REMAINS
The “clinker” is the solid mass that remains unburned in
the burner pot. It contains the inorganic parts of the fuel
and is safe to use as fertilizer or dispose of in a proper
container.
CAUTION
DO NOT OPERATE STOVE WITH BROKEN GLASS.
DO NOT SLAM THE DOOR SHUT.
DO NOT STRIKE GLASS.
DO NOT USE ABRASIVE CLEANERS.
DO NOT CLEAN HOT GLASS.
REPLA C E C E RAMIC G L ASS WI T H FAC TORY
AUTHORIZED REPLACEMENT PARTS ONLY.
THE CLINKER WILL REMAIN HOT FOR SEVERAL
MINUTES AFTER IT IS PULLED OUT OF THE BURNER
POT.
SOOT AND FLY ASH
The products of combustion will contain small particles of fly
ash. The fly ash and soot will collect in the exhaust venting
system and restrict the flow of flue gasses. Incomplete
combustion, such as occurs during startup, shutdown, or
incorrect operation of the parlor stove will lead to some soot
formation which will collect in the exhaust venting system.
The exhaust venting system should be inspected at least
once per month (during heavy use) to determine if cleaning
is necessary. Corn has a high ash content.
DISPOSAL OF ASHES
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,
well away from all combustible materials, pending final
disposal. If the ashes are disposed of by burial in soil
or otherwise locally dispersed, they should be retained
in the closed container until all cinders have been
thoroughly cooled.
EXHAUST AND CONVECTION AIR FILTER
• Remove air filter and replace regularly
• Clean exhaust vent

DAILY MAINTENANCE
AIR FILTER
The surfaces of the stove may be hot. Always wear
protective gloves even when the stove is cool to the touch.
There are two areas that require daily maintenance; (1) the
firebox and (2) the fire pot.
• Remove the top baffle inside the firebox and clean
the fly ash and soot on all exposed parts using a steel
brush and ash cleaning vacuum. The use of a shop-vac
is not recommended. Talk to any authorized dealer for
information about an ash cleaning vacuum.
• The fire pot and the area around it are cleaned using the
special tool provided with the stove and an ash cleaning
vacuum. It is important to remove any unburned pellets
that may have fallen behind the burn pot.
• Complete the daily maintenance by checking the seal
on the doors. Look for pellets that may have been left
behind during loading. Check that each of the door seals
are flush with the stove and sealing properly.
WEEKLY MAINTENANCE
• To clean fire pot with cleaning tool, remove fire pot by
unscrewing the small spring from the lower cleaning
rod. Remove rod and pull out fire pot. Hang on to end
of cleaning tool with the hole in it. Scrape the fly ash
that has fallen through the holes of the plate in the gap
that sits below the fire pot.
• Remove the ash pan and dump the ash into a metal
container.
• Cleaning of the exhaust system will depend upon the
ash and debris content of your fuel. If your fuel has a high
ash content and/or significant debris in it, the exhaust
system will require weekly cleaning. Cleaner fuels will
allow for monthly cleaning of the exhaust system. If you
have installed clean out tees you will need to check for
cleanliness.
NOTE: A clean unit burns efficiently and will remain
trouble free!

SHOULD BE RETAINED IN THE CLOSED CONTAINER
UNTIL ALL CINDERS ARE NO LONGER WARM.
SEASONAL CLEANING
Once every year you must clean out all of the fuel in the
hopper, firebox area, ash pan and fire pot area. Corn and
any ash can accumulate moisture over the summer months
causing the unit to rust and the fuel to mold.
It is recommended that prior to shutting down the unit in
the spring it is run on the high setting for about six hours to
help clean out the heat exchanger system, venting system
and firebox area.

Page 26
When the unit is cleaned out, empty the hopper, take
the venting apart and clean out the fly ash, rinse and let
dry. Inspect the draft blower and clean out all areas such
as back heat exchanger and lubricate the auger, auger
tube, and fire pot area. (Something like vegetable spray
works great to coat the inside of the unit and the moving
parts). Clean the glass, doors and outer cabinet so that
you are ready for the next heating season. Use of an ash
vacuum makes the clean out easier and faster.

the ON key to return to normal operation.
NOTE: If this problem persists, check the door seals
are in good condition on both the ash door and the
glass door.
COOL DOWN MODE
OVERTEMP SWITCH
HOPPER OPEN
FEED AUGER OFF
Problem: The hopper door has an interlock that stops the
auger from operating. This is to assure that no injuries
occur with the hopper open.
Remedy: Close hopper door.
Note: If the door remains open for an extended period
of time the fire will go out. Closing the door promptly
will eliminate the need to start the fire over.
COOL DOWN MODE
LOSS OF FIRE/OFF
PUSH OFF/ON TO
RESTART STOVE
Problem: These two screens are used to instruct you to
push the OFF/ON key because the fire has gone out. The
common reasons for this are:
• The fuel selected during the startup was not correct
and the feed rates are usually too much to sustain a
flame.
RESET OVERTEMP
BUTTON / RESTART
Problem: The temperature of the exhaust has exceeded
a safe operating level and the stove will shutdown when it
has cooled to a safe level.
Remedy: The first action that should be taken when
seeing the alternating screens is to check all areas around
the stove for excessive heat. Causes for exceeding the
overtemp limit are as follows:
• Circulating air filter plugged.
• Excessive room temperature.
• Plugged circulating fan.
• Faulty circulating fan.
• Dirty heat exchanger.
