CAUTION
Installation and repair of this parlor stove should be
done by a qualified service person. The appliance
should be inspected before use and at least annually
by a qualified service person. It is imperative that
control compartments, fire box, and circulating air
passageways of the stove be kept clean.
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 of the room
accompanying the parlor stove. If not, the pressure
switch may shut off operation of the parlor stove.
The moving parts of this stove are propelled by
high torque electric motors. These parts can cause
severe damage to body parts that get near them.

Congratulations on your investment in quality. 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 the highest 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.
BURNING SOLID FUELS
Ashes need to be removed from the stove periodically.
See the “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.
This parlor stove has been designed to burn dry shelled
corn, wood pellets and cherry pits.
SHELLED CORN
• Corn must 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
screened corn only. Stalk parts, excessive fines and
cob remnants will clog the air flow holes in burn plate.
Check the corn for foreign objects.
• Store the corn supply in a dry place and keep the 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. Each variety has
unique characteristics including the shape and size
of the kernel. As corn characteristics change, the fuel
range may have to change accordingly. SEE FIGURE
2.
INSTALLATION AND OPERATION MANUAL
Models MF3700, MF3800
WARNING
NEVER BURN SEED CORN IN THE 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 “DE ER CO RN”. IT FR EQUEN TLY
CONTAINS MOLASSES SUGARS.
NEVER BURN CORN WITH A HIGH WAX CONTENT.
DO NOT STORE ITEMS SUCH AS START PELLETS OR
BURN GEL IN PARLOR STOVE OR WITHIN INSTALLED
CLEARANCES OF PARLOR STOVE.
CAUTION
BURNING ONLY CORN WITH THE RECOMMENDED
MOISTURE CONTENT WILL ASSURE LONGER STOVE
LIFE AND LESS FREQUENT CLEANING.
CAUTION
CUMBERLAND STOVE WORKS DOES NOT RECOMMEND
BURNING THE STOVE ON THERMOSTAT MODE, EITHER
LOCAL OR REMOTE, WHEN BU RNING CORN OR
PELLET BLENDS. SPENT ASH MATERIAL WILL BUILD
UP IN THE POT, INHIBIT THE IGNITOR FUNCTION AND
CAUSE A VIOLENT IGNITION.
CumberlandStoveWorks.com
Figure 2: Feed Rate Chart
Page 7800-345-6007
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.
• Before burning, 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 dust build-up, the hopper will need to be
vacuumed out after every 6-8 bags of pellets—more
often if the pellets are poor quality. You may have to
screen each bag of pellets if dust becomes a problem.
• Wood pellets are 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. 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.
• Cherry Pits are the woody remains of processed
cherries. This fuel can be found affordably in regions
of the country that process cherries.
