INTRODUCTION  
WARNING  
Thank you for purchasing a Cumberland StoveWorks Multi  
Fuel Parlor Stove from Ardisam, Inc. We have worked to  
ensure that the multi fuel burning stove meets high stan-  
dards 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.  
NEVER BURN SEED CORN INTHE STOVE. SEED CORN  
IS TREATED WITH CHEMICAL PESTICIDES THAT ARE  
HARMFUL OR FATAL IF SWALLOWED, SEED CORN IS  
DANGEROUS TO HAVE IN THE HOUSE, ESPECIALLY  
WHERE CHILDREN CAN REACH IT.  
NEVER BURN “DEER CORN”. IT FREqUENTLY  
CONTAINS MOLASSES SUGARS.  
BURNING SOLID FUELS  
NEVER BURN CORN WITH A HIGH WAX CONTENT.  
Ashes need to be removed from the stove periodically.  
See Normal Care & Maintenance section for cleaning  
procedure.  
DO NOT PLACE SUCH ITEMS AS START PELLETS  
OR BURN GEL FUELS WITHIN THE PARLOR STOVE  
INSTALLATION CLEARANCES OR WITHIN THE SPACE  
REqUIRED FOR LIGHTING AND ASH REMOVAL.  
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.  
CAUTION  
BURNINGONLYTHERECOMMENDEDꢀ-ꢀ4%MOISTURE  
CONTENT CORN WILL ASSURE LONGER STOVE LIFE  
AND LESS FREqUENT CLEANING.  
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.  
BURNING WOOD PELLETS ACCORDING TO  
RECOMMENDATIONS WILL ASSURE LONGER STOVE  
LIFE AND LESS FREqUENT CLEANING.  
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.  
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 ꢀ4% 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

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.

OUTSIDE AIR CONNECTION  
WARNING  
Connection to outside the house is REqUIRED for mobile  
home installations.Direct air access must be provided, use  
a Fresh Air Kit (not included).  
DO NOT CONNECT TO ANY AIR DISTRIBUTION DUCT  
OR SYSTEM.  
DO NOT INSTALL IN A SLEEPING ROOM.  
Only noncombustible pipe 2” (or greater) in diameter is  
approved to use for outside air connections (straight or  
flexible).PVC pipe is NOT approved and should NEVER  
be used.  
CAUTION  
THE OPERATION OF EXHAUST FANS SUCH AS  
BATHROOM FANS, ATTIC FANS, ETC. MIGHT STARVE  
THE PARLOR STOVE OF COMBUSTIBLE AIR  
CREATING A NEGATIVE PRESSURE IN THE ROOM.  
PROVIDE ADEqUATE VENTILATION IN THE ROOM  
ACCOMPANYING THE PARLOR STOVE. IF NOT, THE  
PRESSURE SWITCH MAY SHUT OFF OPERATION OF  
THE PARLOR STOVE.  
If the air inlet is connected to the outside, it MUST be  
terminated with a vertical 90º bend (down) or with a wind  
hood.Failure to do so could result in a burn back during high  
winds blowing directly up the air inlet during a simultaneous  
power failure.  
Blockage, excessive length, or extra bends in the air intake  
pipe will starve the stove of combustion air. A 90º bend is  
equivalent in restriction to approximately 30” of straight  
inlet pipe.

VENTING  
WARNING  
The following installation guidelines must be followed to  
ensure conformity with both the safety listing of this stove  
and to local building codes.  
DO NOT CONNECT THIS UNIT TO A CHIMNEY FLUE  
SERVING ANOTHER APPLIANCE.  
DO NOT INSTALL A FLUE DAMPER IN THE EXHAUST  
VENTING SYSTEM OF THIS UNIT.  
note: where passage through a wall, or partition of  
combustible construction is desired, the installation  
shall conform to Can/CSa -8365.  
DO NOT CONNECT DIRECTLY TO A MASONRY  
CHIMNEY.  
TYPE OF VENT  
DO NOTTERMINATEVENT IN ANY ENCLOSED OR SEMI-  
ENCLOSED AREA, SUCH AS; CARPORTS, GARAGE,  
ATTIC, CRAWL SPACE, UNDER A SUN DECk OR PORCH,  
NARROW WALkWAY OR CLOSED AREA, OR ANY  
LOCATION THAT CAN BUILD UP A CONCENTRATION  
OF FUMES SUCH AS A STAIRWELL, COVERED  
BREEZEWAY ETC.  
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.  
CAUTION  
VENT SURFACES CAN GET HOT ENOUGH TO CAUSE  
BURNS IFTOUCHED BY CHILDREN.NONCOMBUSTIBLE  
SHIELDING OR GUARDS MAY BE REqUIRED.  
PELLET VENT MUST MAINTAIN A MINIMUM 3 INCH  
CLEARANCE TO ANY COMBUSTIBLE.  
PELLET VENT INSTALLATION  
Termination must exhaust above air inlet elevation.  
Installation MUST include three vertical feet of pellet vent  
pipe.  
INSTALL VENT AT CLEARANCES SPECIFIED BY THE  
VENT MANUFACTURER.  
ALL VENTING,WHETHER VERTICAL OR HORIZONTAL,  
JOINTS SHOULD BE MADE GAS TIGHT WITH  
RECOMMENDED SEALANTS.  
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.

OPERATING INSTRUCTIONS  
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. TheTRI-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 BYTEMP kEY {heat level

NORMAL CARE & MAINTENANCE  
CAUTION  
DO NOT OPERATE STOVE WITH BROkEN GLASS.  
DO NOT SLAM THE DOOR SHUT.  
DO NOT STRIkE GLASS.  
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.  
DO NOT USE ABRASIVE CLEANERS.  
DO NOT CLEAN HOT GLASS.  
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.  
REPLACE CERAMIC GLASS WITH FACTORY  
AUTHORIZED REPLACEMENT PARTS ONLY.  
THE CLINkER WILL REMAIN HOT FOR SEVERAL  
MINUTES AFTER IT IS PULLED OUT OF THE BURNER  
POT.  
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.  
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.

DAILY MAINTENANCE  
WARNING  
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.  
WHEN PERFORMING ANY INTERNAL ELECTRICAL  
MAINTENANCE  
MOVING PARTS INSIDE OF THE CABINET MAY  
CAUSE INJURY. DO NOT OPERATE UNIT WITH  
PANELS REMOVED OR OPEN.  
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.  
HOT PARTS. DO NOT OPERATE THE UNIT WITH  
PANEL OPEN.  
RISk OF ELECTRIC SHOCk. DISCONNECT POWER  
BEFORE SERVICING UNIT.  
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.  
INTHE EVENT OF COMPONENT FAILURE, REPLACE  
WITH THE ORIGINAL FACTORY EqUIPMENT.  
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.  
CAUTION  
THIS IS A MINIMUM REqUIREMENT FOR SOOT  
AND FLY ASH REMOVAL. ASHES SHOULD BE  
PLACED IN A METAL CONTAINER WITH A TIGHT  
FITTING LID. THE CONTAINER SHOULD BE PLACED  
ON A NON-COMBUSTIBLE FLOOR, WELL AWAY  
FROM COMBUSTIBLE MATERIALS, PENDING FINAL  
DISPOSAL. IF ASHES ARE DISPOSED OF BY BURIAL  
IN SOIL OR OTHERWISE LOCALLY DISPERSED, THEY  
SHOULD BE RETAINED IN THE CLOSED CONTAINER  
UNTIL ALL CINDERS ARE NO LONGER WARM.  
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.  
TER  
AIR FIL  
note: a clean unit burns efficiently and will remain  
trouble free!  
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.

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.

INSTALLATION AND OPERATION MANUAL  
MF3500G, MF3500S, MF3500B Models  
UNDERSTANDING THE FAULT SCREENS  
The door was open for more than five minutes.  
The hopper has been emptied of fuel.  
STARTUP CHECK  
EXHAUST OFF  
Remedy: Wait a minimum of 30 seconds, push OFF key  
until [SELECT FUEL TYPE USE MODE kEY] appears.  
The normal start sequence will begin.  
Problem: The ON key has been pushed for start and the  
POV (Proof of Vacuum) switch has not detected vacuum.  
There is a 15 second delay waiting for the start cycle to  
continue before the screen [START CHECk EXHAUST  
RUNNING] appears.  
VACUUM FAULT  
PUSH OFF/ON KEY  
Remedy: Check for open door or gasket leaks. Restart  
the stove.  
Problem: This message will be displayed if the door is  
opened or the vacuum in the burn chamber is lost because  
of a leak or the ash pan is removed for a long period of  
time.  
NO FUEL SELECTED  
USE MODE KEY  
Remedy: TRI-X controller will instruct you when to push  
the ON key to return to normal operation.  
Problem: The screen waits for you to push the MODE  
key. If any other key is pushed on the TRI-X controller,  
the display will alternate between [NO FUEL SELECTED  
USE MODE kEY] and [SELECT FUELTYPE USE MODE  
kEY].  
note: if this problem persists, check the door seals  
are in good condition on both the ash door and the  
glass door.  
Remedy: Push MODE key and select the type of fuel in  
use.  
COOL DOWN MODE  
OVERTEMP SWITCH  
HOPPER OPEN  
RESET OVERTEMP  
BUTTON / RESTART  
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.  
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: Close hopper door.  
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:  
note: if the door remains open for an extended period  
of time the re will go out. Closing the door promptly  
will eliminate the need to start the re over.  
Circulating air filter plugged.  
Excessive room temperature.  
Plugged circulating fan.  
Faulty circulating fan.  
COOL DOWN MODE  
LOSS OF FIRE/OFF  
PUSH OFF/ON TO  
RESTART STOVE  
Dirty heat exchanger.  
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.
