Three Pronged Plug (Grounded)
Ash Drawer
Your stove has a printed circuit board and other
electrical components that require a grounded circuit
and proper polarity. Purchasing a surge protector
provides additional insurance against unnecessary
problems.
Control Panel/Fan Rheostat
The ash drawer located in the front of the pedestal is
designed to make cleaning easier by containing the
ashes in a removable drawer. It is accessed by
turning the spring loaded screws located on the ash
drawer cover. Do not operate the stove with the ash
drawer open or ajar. Replace gasket material as
necessary to insure a tight seal.
The primary control .board manages the performance
of your stove. It allows you to regulate the fuel feed
rate, the draft fan voltage and main power to the
stove. The room air fan rheostat allows you to
manually regulate the fan speed except when the
automatic high speed override is engaged.
Firepot
Decorative Logs
An important feature of your NaturalFire stove is
the realistic fire created by the flame spread firepot
and the refractory logs. Although the logs are quite
durable, they should be handled carefully, as they
retain heat for a considerable period of time, and if
dropped can break.
The pellet firepot is where the fuel is burned.
Although ithas a self cleaning capability for much
of the ash build up, variable fuel quality (ash
content) and extended periods of a low burn rate
will .necessitate some manual cleaning. An Earth
Stox_e firepot cleaning tool is highly recommended
,(part#1000).
Hopper
The hopper is where the fuel is stored before it feeds
into the stove.
Placement of the logs is important in achieving a
realistic fire. One recommended pattern is pictured
below which allows you to use a Firepot cleaner
without having to remove the logs (except for full
maintenance).
Page 2
INTRODUCTION
How It Works
The fuel metering cup rotates in the throat of the hopper
providing a measured amount of fuel based on the set feed
rate. The fuel drops into the anger tube where it is moved
into the firepot. The draf_ f_n provides combustion air
through the _.ger tube and a series of holes in the inner
firepot, to allow for complete combustiom
The flame and hot gases provide heat to the heat exchange
tubes lorm_ in the upper chamber of the stove. The
room air fan extracts the heat and delivers it to the room,
along With the natural radiant heat from the glass and
metal surfaces.
Gold Door
Your Earth Stove's gold door frame should be cleaned
thoroughly With a good window cleaning solution and a
soft cloth BEFORE the stove is burned. Do not use any
metal polishes or abrasives to clean the door. Any oils or
finge_v_ints leg on the gold could become Iw.u_ent
blemishes if the stove is burned prior to _ removal.
Atkrr the first few fires the gold will cure.
Glass
The glass is a super heat resistant ceramic that withstmds
continuoustemperatums upto 1390° F. This temperature
is well beyond the temperatures in which you operate
your stove.
This appliance is designed to provide a flow of air over
the inmde of the El_% which along with high heat helps
keep it clean. When operating the stove on low for
extended periods of time, the gl___ may get dirty. A
commercial _I_ cleaner designed for stoves is
recommended for cleuning.
The glass should be cleaned thoroughly with glass cleaner
and a soft cloth BEFORE the stove is burned.
Marble Set
Marble is a natural product so each piece will have its
own unique chamc_. Marble may be cleaned With a
damp cloth toremove oils or dust. Be sure to installthe
four cerawool strips (under the rfiarble) to protect it Do
notputro_ objects(suchas_vets,steamers,hopperlid,
etc.) on the _. Do not install the marble before
curing the paint
Remote Wall Thermostat
One way to maxim_ the efficiency and convenience of
your stove is to install a re.mote wall thermostat. A
Honeywell T87F 24 volt thennostat is recommended (see
page5).
Corn Pot
NaturalFire pellet stoves will bum most types of corn with
the _aa_fion of a corn pot kit. For dtcmils, see the section
on burning com.
Several options are availal, le to enhance your NaturalF'ge pe[l_ stovz Please see your local d..-br for further

OPERATION
Before Attempting To Start Your Stove, Read This Manual Thoroughly. Have Your Stove Pretested and
Professionally Installed.
Start Up Procedure
1. Plug in the stove. Fill hopper with pellet fuel.
2. Turn the Main Power Switch to the "Feed
System" position.
3. Provide starting fuel by pushing the "Start
Button" and allow fuel to feed for approximately
five minutes (or put approximately two cups of
fuel directly in the Firepot).
4. Turn the Main Power Switch to the "Off'
position. (This will stop the fuel feed.)
5. Open fire door and apply Fire Starter gel to the
fuel in the Firepot, then light. Allow the fuel to
burn for five minutes with the door slightly ajar.
Shut Down Procedure
1. Turn the Main Power Switch to the "Draft
Fan" position. If using a remote
Thermostat, turn the Thermostat down.
2. When the fire in the Firepot goes out
completely, shut the Main Power Switch to the
"Off" position.

OPERATION
Room Air Fan Rheostat
The room air fan rheostat can be used to vary the
speed of the room air fan by rotating it to the
desired setting. When the stove is very hot
(running on high), the rheostat override (fan speed
disc) will automatically run the fan on high to
prevent the stove from overheating.
• "¢
Normal Operating Sounds
Heat Exchange Tubes - As the room air fans
increase in speed, you may hear air flowing through
these tubes and out into the room.
Thermostatic Control Disc - There are four
different heat activated temperature discs on the
insert. The discs can make a light clicking sound as
they cycle while the insert heats up or cools down.
Room Air Fan - The modern, high efficiency fan
may have a hum or pulsating sound, particularly on
the high setting. The sound may change as the fan
speed is varied.
Auger Feed System - When fuel is fed from the
hopper to the auger tube, a light clinking sound of
the fuel being cut may be heard.
Auger/Cup Motor(s) - When feeding fuel, you
may hear the intermittent buT7 or hum of these
motors.
Draft Fan - This motor runs at various speeds to
provide combustion air to the firepot (and to aid in
the draft of the flue). The speed of this motor wiU
, increase with the feeding of fuel.

OPERATION
Burning Corn (Optional)
Natural Fire pellet stoves will bum most types of
corn with the addition of a compot kit. R is not
necessary to mix corn with wood pellets however,
wood pellets are required to start the fire.
NOTE: Burning treated seed corn is never
recommended
The compot kit consists of:
1 1/8" Filler Plug
1 3/8" Filler Plug
1 Compot
To install the cornpot, simply remove the screw(s)
from the top of the auger housing and lift up and out
on the firepot. Slide mounting flange of the cornpot
over the auger housing and replace screw(s).
Initially the air shutter on the draft: fan should be set
at 1/2 open and the draft fan selector on "LOW". If
more or less combustion air is needed, adjust the air
shutter accordingly to achieve a bright yellow flare e.
Because corn size and density varies, it will be
necessary to calibrate the fuel metering cup in order
to maintain rated BTU input and prevent overfiring.
This requires the installation of the filler plug in the
fuel metering cup. Use the 3/8" filler plug provided
in the compot kit.
The moisture content of the corn should be 15% or
less, and care should be taken to ensure that there
are no foreign objects in the corn (i.e. sticks, stalks,
cob parts, etc.). When burning corn, the primary
combustion takes place on a bed at the bottom of the
compot.
The compot has a solid bottom and sides with air
holes because burning corn forms a fluid-like
residue which becomes solid when cool. The
cornpot cleaning will depend upon the quality and
quantity of corn being used. The compot should be
cleaned when the build up starts to reach the bottom
air holes inside of the compot. You will need to
remove the ash, and in some instances a white
calcium like deposit. The stove must be shut down
and cooled before cleaning.
CORN BURNING SHOULD BE DONE IN TOP
VENT INSTALLATIONS ONLY. .If the
installation must elbow into a wall thimble, the
horizontal mu sl_ould not be more than 24". The use
of a wall mounted thermostat, part #CTR140 is
suggested.
Start Up Procedure
We recommend starting a corn fire with wood
pellets because corn has a dense shell that can be
difficult to start. Manually fill the cornpot, to the
bottom of the auger tube, with wood pellets. Use of
the start button feature is not recommended when
initially starting the unit for corn burning. (See
"Start Up Procedure" in the Operation section for
additional start up information).

MAINTENANCE
Ash Removal and Disposal
CAUTION: BE SURE THE FIRE IS OUT AND
STOVE IS COLD BEFORE REMOVING
ASHES! NEVER BURN YOUR STOVE WITH
THE ASH DRAWER OPEN.
Ashes can hold live embers for several days, and
must be disposed of with care. Be certain the fire is
out before you remove the ash drawer. Brush ashes
into the ash drawer. After emptying, clean and
replace the ash drawer and tighten the spring loaded
screws. NEVER Elace ashes in a cardboard box or
any other combusUble receptacle. Place the ashes in
a metal container with a tight fitting metal lid. The
closed container should be stored on a
noncombustible surface, away from combustible
materials. Keep the ashes in the closed container
until you are certain all the cinders have completely
cooled. Replace ash drawer gasket if it becomes
damaged.
Paint
Your stove finish is a high temperature paint that
•requires time and temperature for the silicon resin in
the paint to completely cure. Depending on your
use, this may take a few hours or a few days. The
paint manufacturer recommends you ventilate the
house during the initial bums. Although the
emis'sion is primarily Carbon Dioxide, there are
other components emitted which make it smell bad
and may irritate some people. Do not place
anything on the stove surface until the paint is
completely cured, as it will become soft durin_ this
process. Do not attempt to repaint the stove unul the
_aint is completely cured. If the surface later
ecomes stained Or marred, it may be lightly sanded
and touched up with spray paint trom the same paint
manufacturer, paint is available at your local
dealer.
KEEP YOUR HOUSE WELL VENTILATED
DURING THE CURING PROCESS. THE
CHEMICAL SMELL AND BLUISH HAZE
EMITTED BY THE CURING PAINT CAN BE
QUITE NOTICEABLE AND MAY SET OFF A
SMOKE DETECTOR.
Fan(s)
At least once each year, check the room air fan and
draR fan inlets for deposits from carpeting, pet hair,
furniture coverings, etc. Use a brush and/or light
vacuuming for cleaning.
Door Gasket
A spun fiberglass gasket (3/4" in diameter) provides
the seal around the fuel door. Should this become
frayed or ,damaged it should be replaced. Spun
fiberglass rope" gasketing can be purchased from
your dealer or some hardware stores. It must be the
same diameter as the original. Use high temperature
(RTV) silicone sealer as an adhesive.
WARNING: MAINTAIN THE DOOR SEAL IN
GOOD CONDITION. DO NOT LEAVE THE
STOVE BURNING WITH THE DOOR OPEN OR
AJAR. DO NOT USE ANY TYPE OFARRASIVE
CLEANER OR POLISH ON GOLD PLATING.
Creosote Formation and Need for
Removal
If your stove is properly adjusted, very little
creosote will develop in your flue system. If
creosote begins to develop, it is likely that poor
adjustment or needed maintenance is causing
incomplete combustion of the fuel. Be sure your
draft fan switch, and draft fan shutter are set
properly.
What causes creosote is the moisture content of fuel
verses the rate at which it is burned. Piloting a stove
on low feed rate for long periods of time, causes
incomplete combustion, cre.atin_ vapors which may
condense in a relatively cool chimney, thus forming
creosote. These deposits tend to form in long runs
of venting where gases cool prior to exhausting.
Soft fly ash is a normal by product of bumingpellet
fuel, and Can accumulate in your flue system. Using
lower grade fuel will increase the frequency of
cleaning that wiU be needed. Check your flue
regularly (at least once a month) until a schedule can
be established for your installation and fuel quality.
Remember, during high use periods to increase your
inspection cycle.
Note: Single wall pi]_e cools rapidly, therefore
installations using this type of flue are more
susceptible to creosote deposits.

MAINTENANCE
Refractory_ Logs
The following steps will insure the longevity of
your logs:
1. Never attempt to handle the logs while they are
hot.
.
Carefully remove logs from firepot when the
stove is cold. Remove ashes from the firepot.
Then carefully place the logs into their proper
position (see page 2).
Firepot
Keep the firepot inner holes free of obstructions
(buildup). Remove the flrepot and empty it when
this occurs.. The quality and quantity of pellets
used will dictate the necessary cleaning. Remove
clinkers or carbon build up.
Clinkers are a byproduct of the fuel. Silica (or dirt)
in the fuel, along with other impurities can fuse
under heat and cause clinkering. Clinkering is a
function of the fuel, not the stove. A clinker should
be removed using a clean out tool.
Cleaning the MP35/50
. Turn the unit off two to three hours before
cleaning to allow the unit to cool (see Shut
Down Procedure).
2. Place protective floor covering around the
front of the stove.
o
,
.
.
o
Remove ash drawer and empty ashes into your
noncombustible container. Dispose of ashes as
previously described (see Ash Removal and
Disposal). Clean any remaining ash from the
firebox and ash drawer area.
After the stove chimney has been swept, the
top/rear chimney seal off plate needs to be
pulled off of the stove to vacuum the unit out.
There is a baffle plate beneath the heat
exchange tubes. Fly ash will acel_mulate on
this plate and must be removed to ensure flail
efficiency. To clean, remove the baffle plate
and pull the cleaner plate all the way forward
and then return to the rear of the firebox.
Remove the clean out access cover and
vacuum out the fly ash (see page 10).
Reinstall your firepot being sure that the auger
tube protrudes about 1/8" into the firepot,
Replace baffle and clean out access. Reseal
and secure stove chimney.
The cleaning frequency will be dictated by the
quality and q, antity of the fuel burned. The
following is the suggested schedule to
establish a minimum: A_Rer every 1/2 ton of
pellets, when the metal surfaces of the
exchange tubes are no longer visible, or after
every 2-3 weeks of use.
3. CAREFULLY remove the decorative logs
from the firebox and set them aside.
4. Remove the firepot by removing screw(s)
from the auger housing and pulling up and out.

.
Remove the baffle plate from the pallet and
place it on the brackets inside the stove. The
brackets are located below the heat exchange
tubes at the rear and above the door at the from.
Make certain the baffle plate is placed all the
way to the rear and left hand side of the unit and
not centered. The heat exchanger cleaner plate
han_es should fit into the two notches in the
baffle plate
Plug the stove into a grounded oulet (using a
circuit tester, verify the electrical outlet for
proper ground and polarity where the unit will
be installed. Failure to do so could result in
damage to the electrical components and void
thewarranty).
Check the shutter on the dra_ fan and make sure
it js set at 1/2 open (once installed the actual
setting will depend upon the dra_ of the flue).
On the primary control board, A) set the main
power switch from "Off" to the "Draft Fan"
position and B) put the fuel feed rate on "Full".
The draft fan should now start. Open the door,
place your hand over the firepot and see if the
draft Fan is forcing air into the firepot. Turn the
main power switch to the "Off" position.
Turn the rheostat "On" to see if the room air fan

INSTALLATION .-
Direct Vent
Although a direct vent flue is an approved
installation, the manufacturer recommends the
outside flue should be installed with a cleanout "T",
and Pellet Vent chimney pipe run up through the
cave. This will eliminate the possibility of siding
discoloration and/or to enhance performance in bad
draw situations. Terminate the pipe using the
standard clearance. Exception: If using a UL listed
Pellet Vent pipe you may use the Pellet Vent
manufacturer's cleara/lces.
IF BURNING CORN, DIRECT VENT IS NOT AN
APPROVED INSTALLATION.
IMPORTANT!! Never turn the Draft Fan Selector
to the "OFF" position on any direct vent
installations. Keep the Combustion Fan Switch on
the Primary Control Board in the "Low" or High"
position. In the event of a toss of power in a rear
vent direct termination application, natural draft is
not present and you may receive smoke back in to
the dwelling that will dissipate rapidly.
To Install
The MP35/50 can be converted to a direct vent by
transferring the top flue outlet to the rear vent
position. Replace the top flue outlet by using the
rear cover plate, removed from the back of the
stove. Follow the directions listed below:
1. Lift off the top louvered trim (A) to access the
top flue outlet. Remove mounting nuts and
starting collar.
2. Remove right side heat shield by removing
screws on rear flange to expose access opening.
3. Remove the rear flue cover plate located on the
back of the stove.
4. Install the gasket (B) and starting collar (C)
making sure the gasket is intact for a tight .seal.
Replace nuts and tighten.
5. Place the rear flue cover plate over the top
opening. Make sure the gasket is in place and
there is a complete seal. Replace nuts and
tighten.
6. Attach section of pellet vent pipe (D). Seal this
connection with high temperature silicone
sealant. Secure the section of pipe with two
sheet metal screws into the starting collar. One
up from the bottom at 6:00 position and one
from the side through the access opening at the
9:00 position. The horizontal run may not
exceed 36 inches..
When rear breaching, a trim kit is available through
your dealer, part number TRK35. It consists of the
1) New louvered top trim, and 2) Two flue seal
gaskets (the additional gasket is provided in case of
accidental damage during installation).
A) Top Louvered Trim Panel
B) Gasket Material
C) 4" Starting Collar
D) 4" pellet pipe, 24" section
E) 4" Wall Thimble
F) 4" Rain Cap

installation, with the following supplemental
requirements per OAR 814-23-900 through
814-23-909:
.
No single wall pipe may be used as a connector
or chimney. Pellet Vent pipe must be used from
stove top to termination.
2. Maximum two offsets permitted.
,
The chimney must provide for a section joint so
that any parts extending above 13' 6" from
ground level can be removed for transportation
of the mobile structure.
o
The stove must be grounded to the mobile home
wailer frame with a No. 8 (minimum) solid
conductor.
5. The combustion air must communicate to the
outside air.
6. Floor protection must cover the area beneath the
stove and extend one inch beyond the base on all
sides.
7. Structural members such as roof trusses or floor
joists cannot be cut or modified while making
the installation.
Outside Air Provision
Although this section applies to a mobile home
installation, it may also be required by local codes in
standard residential installations. Use the
manufacturers optional outside air kit (part #85-35)
or equivalent.
1,
Set the stove in its irmtalled position and select
the floor or outside wail location for the outside
air penetration. The air ducting must connect
with the bottom of the motor cabinet of your

SIX STEP TROUBLESHOOTING GUIDE (Qualified Technicians Only)
Tools Essential For Troubleshooting
I. Stove Installation and Operation Manual.
2. Circuit Tester (Micronta # 22-101 or equivalent).
3. Molex Pin Extractor, I/8" (p/n # 15068).
4. Volt Meter.
ATTENTION: Before attempting any troubleshooting; I) Check your outlet to see that you do have
power and the outlet is wired properly (use circuit tester); 2) Check the flue for blockage; 3) Take the
time to clean the stove; 4) Note the model number of the primary control board (ira model number is
not printed on the face of the primary control board, it is a model: Emerson.)
Step #1
Room Air Fan System Check
Turn the rheostat knob till it "clicks", it is now
"ON". In this position the'room air fan will operate
at full speed (115v). Place your hand in front of the
air outlet to con.firm that air is coming out. Further
rotation of the knob will slow the speed of the room
air fan. On the lowest setting the fan receives
approximately 65 volts. If the room air fan comes
on and operates properly (as described), the source
of the problem will not be the rheostat, room air
fan, fan speed disc, wiring connections or circuitry.
Should the room air fan fail to come on, the first
step in finding the problem is to check the power
source (using a circuit tester or simply plug a lamp
or other small appliance into the outlet). Once it has
been determined that there is power to the outlet,
the room air fan motor can be checked by removing
the leads from the molex connector and connecting
them to a l15v power source. If the room air fan
runs, the problem is a loose connection. If the
room air fan fails to run, replacement of the fan will
be necessary.
Step #2
Confirm Power to primary Control
Board
Turn main power switch from the "OFF" position
to the "DRAFT FAN" position. If the red indicator
light comes on, there is power to the primary
control board. If the light does not come on, check
the following:
A. Power source (see Step #1)
B. Fuse
C. High limit manual reset discs
D. High limit auto reset disc
If the fuse is not blown and the high limit manual
reset disc has not "popped out", inspect the molex
connectors and be certain the pins are making
proper contact. Then, using a volt meter, check for
power at the power switch. If the volt meter
indicates 115v and the red indicator light is not on,
it will b e necessary to replace the primary control
board.
Page 18
SIX STEP TROUBLESHOOTING GUIDE- (Qualified Technicians On!y)
Step #3
Confirm Draft Fan Operation
Set the main power switch to the "DRAFT FAN" position
then set the fuel rate switch to the "FULL" position. The
drai_ fan should now operate at full power (aprox.ll5v).
During the piloting process, the draft fan will operate at
thefollowingspeeds:
Switch Position Voltage
High 70-75v
Low 60-65v
Off 0v
To check the daft fan when the stove is cold, check for
movement of air by placing your hand in or near the
firepot If the movement of air is not obvious, inspect the
draft fan to be certain the air shutter is opera If the air
shutter is open and the draft fan is not running, check it by
usingtherroacedureinStep#Lr_-,agaph2.
Step #4
Inspect Fuel Metering Cup for Blockage
To inspect the fuel metering cup, FIRST:
• UNPLUG THR, POWER CORD.
• NEVER PUT YOUR FINGERS IN THE FUEL
CAVITY OF THE METERING CUP.
Remove all the fuel from the hopper. Reach down inside
the hopper and rock the fuel metering cup back and forth
(beingewefulnottoputfingersin fuel cavity of metering
cup). The cup should move approximately 1/4" in either
direction. If it does not move, something is jamming it
(usually a foreign object) and will have to be removed by
using one of the following methods:
A. Using a tool, such as a slotted s_tcv_ driver, clear the
obsm_on (between the fuel cavity of the
metering cup and the blade).
, vity
Blade-/ " Obstruction
B. Locate the metering cup motor cooling propellor on
the back of the appliance and turn it by hand in the
reverse direction until the metering cup rotates
back far eno,_h to clear the obsmx_don.
C. If procedures A or B fails to clear the obstruction,
then remove the metering cup motor and metering
cup to find and clear the obstruction_
Step #5
Confirm Cup and Auger Motor Operation
Set the main power switch to the "FEJ_r3 SYSTEM"
position. Press the "START' button. Both the cup and
auger motor should start. If the motors run but the fuel
metering cup and/or auger does not turn, check the cast
iron coupler on the ends of each motor shaft to make
certainthe set serew is fight on the flat part ofthe shatL If
the motors are not Droning, use a volt meter to check for
line voltage (115v) at the molex connector or check them
by asing the procedure described in Step #1, paragraph 2.
Note: Anytime you are checking the motors, you should
verify the speed at which the motors are turning. This can
be accomplished by timing the revolu_on of the coupler.
Using the set screw as a reference point, the bottom motor
(auger) will make approximately one revolution in 10
seconds. The top motor (cup) will make approximately
one revolution every 48 seconds.
