ECHO PELLET E.I. II
PELLET HEATER
GENERAL INFORMATION
Installation and repair should be done by a qualified
service person. The heater should be inspected
before use and once a year by a qualified service
person. More frequent cleaning may be required due
to fuel quality, excessive lint from carpeting,
bedding material, etc. It is imperative that control
compartments, burners, and circulating air
passageways of the heater be kept clean.
NOTE: During the first few burns the hightemperature paint and sealant used in manufacture
will emit some odor and smoke. Open doors and
windows to the outside for proper ventilation during
the first burn cycle and curing of the paint.
This heater, when installed, must be electrically
grounded according to local codes or, in the absence
of local codes, with the National Electrical Code,
ANSI/NFPA 70-1987.
The Echo Pellet E.I. Heater has been designed and
approved for burning wood pellet fuel only.
Burning solid fuel in other forms is not permitted
and will void all warranties. Pellet fuel should be
¼” diameter and ½” to 1” long.
Provide adequate clearances around air openings
leading into the combustion chamber. Provide
adequate accessibility clearance for servicing and
proper operation. Never obstruct the front opening
of the heater.
Store fuel in a covered, dry area. Pellet fuel bags
can absorb moisture and must be kept dry. Never
place fuel bags next to heater. Maintain minimum
clearances to combustibles at all time.
The heater may be installed as a free-standing unit
mounted on a non-combustible protective floor pad
or hearth. Or it may be mounted into an existing
UL-approved wood stove chimney. Noncombustible floor protection is required and must be
used when placing the heater on any combustible
material.
This unit has been approved for use with a 3" and
4” Type L Pellet Vent System. On runs in excess
of 10' and installations per FIGURE 7, the 4” pipe
must be used.
NEVER use gasoline, gasoline-type lantern fuels,
kerosene, charcoal lighter fluid, or similar liquids to
start or "freshen up" a fire. Keep all such liquids
well away from the heater while it is in use.
THE
ECHO
REQUIRES
OUTSIDE
COMBUSTION AIR ON ALL INSTALLATIONS.
NO EXCEPTIONS ALLOWED (see FIGURE 2).
CAUTION: Do not connect this unit to a chimney
flue serving another appliance. Do not install flue
damper in the exhaust venting system of the unit.
Ashes should be placed in a metal container with
tight-fitting lid. The closed container of ashes
should be placed on a non-combustible floor or the
ground, well away from all combustible materials,
pending final disposal. If the ashes are disposed of
by burial in soil or otherwise locally disbursed, they
should be retained in the closed container until all
cinders have been thoroughly cooled.

5. Keep front door of appliance thirty-six (36)
inches from combustibles (drapery, furniture).
INSTALLATION
1. When deciding on the location of your heater
and vent pipe, minimize the alteration and
reframing of structural components of the
building. Vent pipe must be installed so that
access is provided for inspection and cleaning.
6. When installing the exhaust vent into an
existing chimney, a clean out tee must be
installed behind the heater before going up into
the chimney. This is necessary in order to
remove the fly ash accumulation.
2. Avoid installing heater in high-traffic areas.
Keep children well away from heater when in
operation.
7. Install vent at clearances specified by the vent
manufacturer.
3. A 3-inch clearance to combustibles must be
maintained for horizontal and vertical
venting. When passing through ceilings or
walls, a listed wall thimble must be used,
making sure all combustible materials and
insulation products are a minimum of 3 inches
away from the pellet vent pipe. If using the
Pellet Pro, a 1” clearance is required.
8. Exit termination (distance to openings):
4. A non-combustible hearth pad must be used if
installed on a carpet, wood floor, or other combustible material (see FIGURE 3). Maintain 6”
(152mm) beyond the front and beyond each side
of the fuel loading and ash removal opening.
a.
3 feet minimum above any forced air
inlet located within 10 feet.
b.
4 feet minimum below and horizontal to
any door or 1 foot minimum above any

9. The pellet heater must be operated with a power
source and will not operate using natural draft.
If there is a power failure the heater will shut
down. If the 12-volt back-up system is installed,
the heater will automatically switch to the 12volt power.
Horizontal runs must be limited to 2 feet. On
vertical runs on an exterior wall, a wall
band is required every 4 feet.
b. All pellet vent pipe connections including
exit at the rear of the heater should be
secured with three screws and sealed with
high temperature silicone (450 degrees) or
metallic duct tape. This prevents smoke and
soot leakage into the living area. If this is
not done, there is a possibility that the room
fan will pick up any leakage and blow it into
the room. This requirement is waived if the
new Dura Vent Pellet Pro pipe is used.
Route the power supply cord so it does not
touch any of the exterior components of the
heater.
a. When exiting through the wall with Type
"L" pellet vent pipe, exit straight out through
a wall thimble. Connect a pellet vent tee and
extend the vent pipe at least 5 feet vertically
outside to provide good draft and allow the
gases to exit. The tee must have a clean out
cap for inspection and regular cleaning (see
FIGURE 4). Whenever the pipe run in any
installation is 10 feet or more, the use of 4inch Type "L" vent pipe is required.
c. Installation per Figure 7 requires 4” pellet pipe.
10. Outside Air Hook-up: Thelin Hearth Products
recommends using a Dura Vent Wall Thimble
with a built-in outside air hook-up and flex
tubing.

6. Be aware that the life of the igniter is affected
by the ash build up in the fire pot and the
number of times the stove is cycling on/off. If
more than four or five times a day then you
should switch to the Hi/Low mode. Check fire
pot frequently for ash build up.
The wall thermostat is designed to automatically
regulate the room temperature by shutting the stove
on and off or changing the output from High to
Low. Remember to leave the control knob on the
High or Medium position when utilizing the wall
thermostat feature.
IMPORTANT: Any electrical work performed on
the Echo should be done by qualified personnel.
Always plug AC cord in before DC battery.
A wall or remote thermostat can be hooked to run
the Echo 3000 E.I. automatically. The following is a
step-by-step procedure for installing the optional
thermostat. Note connection terminals on the
bottom right side of the unit (see FIGURE 8). Use
18/2 thermostat wire for installation.
1. UNPLUG HEATER FROM WALL OUTLET
2. Hook up the thermostat wires to terminals (see
FIGURE 8). Remove copper shunt. Replace
shunt if thermostat hook-up is disconnected. If a
remote thermostat is used, mount the “receiver”
to the bottom of the stove with Velcro and then
hook up receiver wires to the terminal (see
FIGURE 8). Follow thermostat manufacturer’s
instructions.
3. Locate thermostat approximately 10 to 12 feet
from heater or in an area that requires steady
temperature. Run thermostat wires from heater
to thermostat along wall or under carpet, etc.,
and hook wires to thermostat terminals.
Designate a central location that will maintain
room temperature and leave remote in that area.
4. Make sure all wiring is complete before
plugging the Echo back into the wall outlet.
5. The thermostat can run the stove either ON/OFF
or HI/Low. Factory setting is ON/OFF.
Changing the Type setting jumper on the circuit
board will switch to the Hi/Low mode (see
FIGURE 15). This should be done in extremely
cold climates so the house will maintain an even

START-UP AND OPERATION
A. Filling the Hopper and Start-Up
CAUTION: Fuel hopper lid must be closed before
operating the unit. The Echo will hold
approximately 50 pounds of pellets.
IMPORTANT: The quality of pellet varies from
brand to brand. This will affect the efficiency of
your heater. Try several brands to find one that
provides a clean, efficient burn.
DO NOT OVERFILL THE HOPPER
IMPORTANT: The fire pot must be seated flush
and must sit even in the fire pot tray. Air leakage
around the fire pot will create a poor burn (see
FIGURE 10).
The Echo will hold approximately 50 pounds of
pellets.
Open the top cover and fill the hopper with pellets
(see FIGURE 9).

ECHO PELLET E.I. II
PELLET HEATER
B. Lighting Instructions
The Echo E.I. has automatic ignition. Simply plug
in the stove, fill with pellets and push the low,
medium or high button on the control panel. When
the button is pushed to low, medium or high the
igniter will come on and in one minute the feed
motor will activate and begin feeding pellets. In
three or four minutes flames should be visible. In
six minutes the igniter will shut off. The LED next
to the button will blink during the six-minute startup period. During the start-up period the heater will
only run on “Low.” If the fire does not reach
operating temperature during the start up period the
stove will shut down, repeating this process will be
necessary.
NOTE: Pellets will not feed when the “Fan” only
button is selected on the Control Panel .
Follow the thermostat manufacturer’s instructions
carefully when using a wall or remote thermostat.
Ensure the built in thermostat terminals on the
bottom of the stove are used (See FIGURE 8). It is
recommended the heater is run on “High” for
approximately 30 minutes to get the heat exchanger
hot before turning it to “Low.” Burn the heater for
a few hours before deciding which setting is
optimal.
FIGURE 11
C. Control Functions
The control functions on the Echo are as follows:
OFF, FAN, LOW, MED, HIGH, and CLEAN (see
FIGURE 11).
1. Fan Position: In the “Fan” only position the
stove will not feed pellets. Use the fan when
starting the stove manually during power failure
and/or if using the 12V battery back-up. The
“Fan” position can also be used if pellets pile up
and need to be burned down before feeding
more pellets. In the “Fan” only position, the
stove will go through the start-up cycle again
when “Low,” “Med” or “Hi" is selected.
2. In the "Low" position, the Echo will feed
approximately 1 to 1.5 pounds of pellets per
hour. The flame will fluctuate between 1 inch
and 6 inches in height.
3. In the "Med" position, the Echo will feed
approximately 3 pounds of pellets per hour. The
flame will fluctuate from 3 to 8 inches in height.
15
ECHO PELLET E.I. II
PELLET HEATER
4. In the "High" position, the Echo will feed
approximately 5 pounds of pellets per hour. The
flame will fluctuate between 3 inches and a full
flame. The fan speed will increase accordingly
as the heater automatically adjusts itself based
on the temperature inside the heater.
present. Maintenance is required and thorough
cleaning and pipe check must be performed if these
conditions persist.
Battery Light: When the green light is blinking the
battery is charging. When the green light is steady
the battery is fully charged. If this light is red, then
the battery terminals are plugged in backward.
5. The "Clean" position is to be used only when
the heater is not burning in order to clean out the
combustion housing and fan blades. See the
"Hopper
Clean
Out"
section
under
"Maintenance Procedures."
Trim Button: On the left side of the control panel
there is a small, round button that will turn
clockwise and counter-clockwise. This button
controls the feed rate in each setting—Low, Med,
and High. Turning the button clockwise will
increase the feed rate in each setting. Turning the
button counter-clockwise will decrease the feed
rate.
6. To turn off the heater while it is running, simply
push the "Off" button on the Control Panel. A
remote or wall thermostat will turn off the stove
automatically when the desired room
temperature is reached. The heater will
continue to run until it cools down. It will
then automatically shut down at 58 degrees
Fahrenheit or in 25 minutes, whichever comes
first.
CAUTION: Move this button carefully. It is
designed to fine-tune the heater in each position in
the event different brands of pellets are used and/or
the stove is operated at a higher elevation.
7. CAUTION: Each feed position will fluctuate
because the microprocessor automatically
adjusts the feed and air based on temperature.
This means the pellet feed rate and flame height
will change accordingly based on quality of
pellet and heat loss of dwelling.
BATTERY OPERATION
Always plug AC cord in before DC battery.
1. The battery must be one foot from the stove to
ensure that the terminal does not touch any part
of stove.
DO NOT OVERFIRE. If pellets pile up
excessively and stove is not burning properly it
should be shut down and thoroughly cleaned.
Use the “Trim” button to adjust feed rate.
2. The Echo Pellet 12V back-up can be purchased
as an option and includes the following
components:
HIGH TEMP/FLUE AND TRIM
INDICATORS
High Temp/Flue: There is a small window to the
left of the fan button that will blink red if the flue
pipe becomes obstructed or there is a high wind
condition, creating a back draft. If there is problem
with the fan guard becoming blocked due to dust
and lint build up then this light will come on and
stay steady red. The feed will shut off and the stove
will shut down when these two conditions are
a.
Deep cycle seated 12-volt gel cell battery.
b.
Battery connector cables for hook-up to
the heater (available from your dealer or
Thelin Hearth Products).
3. To hook up the battery and engage the 12-volt
back-up system, do the following:
a. Connect the red battery cable to the (+)
positive terminal on the battery. Then plug
the red banana plug into the red receptacle
16
ECHO PELLET E.I. II
PELLET HEATER
on the stove. The red must be plugged in
first before the black (see FIGURE 8).
MAINTENANCE PROCEDURES
CAUTION: Moving parts may cause injury. DO
NOT operate with rear cover removed.
b. Connect the black battery cable to the (-)
negative terminal on the battery. Then plug
the black banana plug into the black
receptacle on the stove. When the cables are
hooked up correctly, the LED light on the
control panel will illuminate and glow
green. If hooked up improperly, this LED
will glow.
WARNING: Risk of electrical shock. Disconnect
all power before servicing.
Always turn heater off and let it cool before
cleaning.
Your Echo Pellet Heater requires routine
maintenance for maximum performance, and it is
mandatory for the warranty to remain in effect.
WARNING: Make sure the red cable goes to
the red terminal (positive connector) and the
black cable goes to the black terminal (negative
connector).
The following procedures should be studied
carefully and performed regularly as indicated.
4. A sealed gel cell battery is recommended when
using a 12-volt back-up system. Failure to
install the proper battery could cause
physical harm to you and/or your property
and will also void the heater warranty.
Soot and Fly Ash: Formation and Need for
Removal: The products of combustion will
contain small particles of fly ash. The fly
ash will collect in the exhaust venting
system and restrict the flow of the flue
gases. Incomplete combustion, such that
occurs during start-up, shutdown, or
incorrect operation of the room heater, will
lead to some soot formation which will
collect in the exhaust venting system. The
exhaust venting system should be inspected
at least once every year to determine if
cleaning is necessary.
5. When the battery is properly connected and the
heater plugged in, the following will happen
automatically:
a.
The heater will automatically switch to 12volt power if there is a power failure and
switch back when power is restored.
b.
The battery will be trickle charged as long
as the heater is plugged into 110 AC wall
outlet. Do not use extension cords. The
trickle charge will not recharge a low or
dead battery, but will keep a charged
battery at maximum performance. Do not
unplug stove for the summer and keep
battery attached. Battery will drain
down and fail to recharge.
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 non-combustible floor or
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 thoroughly cooled.
6. The automatic ignition feature will not work on
DC power only. The automatic ignition feature
will not work on DC power only. Contact your
Dealer for manual start instructions.

around and below the pot should be
checked every five or six days depending
on how many hours a day the heater is used
and the quality of the pellets being burned.
Remove the fire pot holder for thorough
cleaning (see FIGURE 12).
FIGURE 12
Open door and remove clean out cover
screws. To remove, simply unscrew and lift
out from each side (see FIGURE 12). Clean
one side at a time. With covers removed,
leave the door open and push the “Clean”
button. Let heater run 30 seconds, push to
“Off,” and replace cover. Remove the
remaining clean out cover and repeat
procedure for other side.
b.
Vacuum inside stove ash pockets on both
sides of fire pot and heat exchange tubes.
c.
Remove fire pot by lifting up and out. It
may be brushed out or vacuumed. Fire pot
should be cleaned regularly. Make sure
slots in pot are not plugged. The area
Scrape pellet feed chute with putty knife to
remove hardened material on which
sawdust can accumulate.
e.
The tee connector on the vent pipe must
have a clean out cap and this must be
checked every four to six weeks or
whenever the "Clean" mode on the Control
Panel is utilized.
a.
Fly ash can also accumulate in the vent
pipe. Inspect the exhaust system frequently
to maintain free flow of exhaust fumes.
This depends entirely on the quality of the
pellets. Initial monitoring of the build-up in
the vent pipe is necessary. Those
installations going into an existing flue
must be installed with a tee connector to
allow access to clean the ash from the pellet
vent pipe.
1. Hopper Clean Out: Vacuum the accumulated
saw dust in the hopper weekly. Keep free of
debris and foreign material. An accumulation of
saw dust can cause irregular pellet feed. For best
results this should be done on a regular basis
depending on how often the heater is used. This
should be done every eight to ten days.
Here are some other maintenance procedures
that should be performed on a regular basis.
a.
d.
2. Cleaning the Exhaust Fan Blade & Heat
Exchanger: The exhaust blower should be
checked for excessive fly ash buildup. Regular
and routine maintenance utilizing the clean out
feature will keep the exhaust blower housing
and fan blades clean. This cleaning can only be
done when the heater is not burning. For best
results, run the fan in the "Clean" position with
the door open for approximately 45 seconds or
until ash is no longer being picked up by the
fan. Always check the clean out cap on the tee
after utilizing the clean feature (see FIGURE

causing the jam. ENSURE THE POWER IS
OFF. Remove any foreign material or object and
restart the heater. CAUTION: Keep fingers and
hands clear of the feed mechanism when heater
is on.
3. Cleaning the Fan Guard: The plastic fan guard
on the rear of the stove must be kept free of lint
and dust. Check weekly for lint build-up and
vacuum as necessary (See FIGURE 2).
3. Problem: Pellet overfeed.
Solution: When the pellets are overfeeding, it
usually means that the air flow has been
reduced. Check the fire pot air intake holes to be
sure they are clear. Check to see if fire pot was
properly seated in the pot tray. If low-grade
grade pellets are used and clinkers (fused ash
and dirt) form in the bottom of the fire pot and
chock the air intake, consider changing the
brand of pellets to one that burns cleaner.
Ensure the fire is out before removing and
cleaning the fire pot. Never vacuum out the
heater when the heater is in operation. The
hot ashes can lodge in your vacuum cleaner
and cause a fire Clean the heat exchanger
manifold (see FIGURE 12) regularly to ensure a
good air to fuel ration, thus allowing the heater
to "breathe" properly. Check the tee and vent
pipe to ensure they are not clogged and full of
ash.
4. Keeping the Glass Clean: If soot deposits
accumulate on the glass, clean with window glass
cleaner and a paper towel when glass is cold.
TROUBLESHOOTING
The following scenarios are provided in order to
help locate a difficulty if the heater performs in a
manner which would seem to indicate a
malfunction:
1. Problem: Stove has pellets but pellets do not
ignite.
Solution: Check power cord to see that it is
plugged in tightly to the bottom of the stove. Is
the LED light blinking when you push the Low,
Medium, or High button? If not, check the fuse
for the igniter located on the bottom of the stove
in the red fuse holder. The timer on start-up runs
approximately six minutes. If, during this time,
the pellets have not lit, the start-up sequence
may have to be repeated. The stove only runs on
one speed until a temperature is reached which
activates the run mode. This usually takes 15 to
20 minutes, and in extremely cold climates, the
start-up procedure may have to be repeated for
the stove to reach this temperature.
4. Problem: Soot is forming on the door glass.
Solution: Black soot forming on the door glass
means that the combustion is not right and the
heater needs to be cleaned. Some brands of
pellets burn much richer than others, try
different brands of pellets and/or have the
air/fuel settings readjusted by your dealer. It is
normal to have the glass cloud up after several
hours of burning, but it should wipe off with a
good window cleaner. If the glass turns black
quickly, clean the heater thoroughly.
2. Problem: Pellets stopped feeding.
Solution: Check pellet supply in hopper. If
empty, fill and follow start-up procedure.
Occasionally, a foreign object, debris, or an
excessive amount of sawdust can enter the feed
mechanism and jam the feed chute. If this
occurs, TURN THE POWER OFF, empty the
hopper and check the feed chute to see what is
5. Problem: Heater emitted smoke for about five
minutes after power failure.
Solution: If the heater emits smoke during a
power failure and frequent power failures are

expected, purchasing a battery back-up system
is recommended. If the vent pipe is installed
according to these instructions, the smoke will
siphon out of the pipe in most instances.
9. Problem: Stove shuts off when running on low.
Solution: Feed is too low. Adjust feed trim
button (turn clockwise) until feed can maintain
fire.
6. Problem: The heater suddenly stopped and the
red light under the control panel came on.
Solution: The High Temp/Flue indicator light
indicates that fly ash has built up in the exhaust
system and/or there is a restriction in the
exhaust/flue system or a high-wind condition.
Check the pipe system for excessive ash and
clogging, particularly the vent cap. Remove the
clean out cap on the tee and make sure that ash
has not blocked the exhaust air flow. This
automatic shut down in the event of flue
clogging is a safety feature. If the shut down
occurs, clean your pipe and heater thoroughly. .
If the problem persists, contact your Dealer or
service technician. If the fly ash build-up is
excessive, try another pellet brand. In most
climates the pellets and fly ash can absorb
moisture from the air and create creosote and a
severe clogging problem. The heater warranty
does not cover the quality of the fuels used or
the way they may be handled, either before or
after the pellets are purchased. High-wind
condition may require a high-wind cap. See
Appendix A.
7. Problem: Heater continues to run after power is
turned off.
Solution: This is normal. The exhaust blower
will keep running until it cools down and then it
will automatically turn off. This can vary by the
temperature the exhaust has reached and the
temperature of the cooling air.
8. Problem: Fan motor speed varies, sometimes
running low and sometimes surging. Will run on
"High" or "Clean" but not on "Low."
Solution: Fan motor brushes are wearing out.
Brushes in fan motor need to be replaced.
Contact your Dealer for replacement brushes..

FIGURE 16 – ROUTINE STOVE CLEAN OUT
AND MAINTENANCE
The following is a step-by-step procedure to clean
out and maintain your pellet stove.
1.
Stove must be shut off and completely
cold before performing this
maintenance.
2.
Open door; remove fire pot and cleanout covers.
3.
Vacuum entire inside area, including
heat exchanger tubes (both sides), using
a pellet vac or shop vac.
CAUTION: Do not use a household
vacuum cleaner.
24
4.
Connect vinyl clean-out tube to pellet
vac or shop vac. (An adaptor must be
used to connect to a shop vac. These can
be purchased at hardware stores or home
centers.) Insert the clean-out tube down
between the heat exchange tubes, and
vacuum up the debris. Repeat the
procedure on the other set of tubes.
5.
Turn control knob to “clean” position for
about 45 seconds.
6.
Replace clean-out covers and fire pot.
The stove is now ready to use.

APPENDIX A – WIND WARNING
Additional Venting Problems
Occasionally, the vent configuration can create a
noisy, harmonic condition. This sound can be
eliminated by closing the air damper located on the
air intake tube on the rear of the stove (see FIGURE
2).
This Thelin Pellet Stove is equipped with a blocked
flue/high temp safety sensor that will shut the stove
off if there is a down draft, blocked flue, or high
temperature condition.
If installing the stove on the side of the house that is
hit by prevailing winds (usually 30 to 40 mph or
greater) there is a chance that the sensor will be
activated and the stove will shut off. Should this
occur, run the pipe up vertically through the eave
and use a high wind cap on the vertical termination
(see diagram).
Contact your Dealer if you have any questions
about this potential problem.

APPENDIX C – FINE TUNING
run of pipe (over 10’) will warm the pipe;
consequently, the draw can be intense
enough to suck more heat out of the stove
than is necessary. To make the stove run
efficiently, close the damper about 60% and
see if the heat output increases. If, the pellets
are not getting enough air, then opening the
air damper may help. Increasing the
combustion air utilizing the procedure in #3
may also help.
Because of the variability of pellets (i.e., length
thickness, density, quality of sawdust), fine
tuning may be required for your heater to
compensate for pellet quality. Following are
some suggestions for fine tuning.
There are three (3) fine-tuning adjustment
components:
1. The Trim Button located on the control plate
(see FIGURE 11) changes the feed rate on
each setting (i.e., Hi, Med, Low). Turning
the trim button clockwise will increase the
feed rate. Turning the trim counterclockwise
will decrease the feed rate. For example, if
the pellet being used is a hardwood pellet
and longer than 1”, then the stove could go
out on the low setting for lack of fuel. Turn
the trim clockwise to increase fuel and thus
sustain the fire.
3. The Fan Trim Pot Adjustment is located on
the circuit board (see FIGURE 15). Note the
two fan trim pots marked on the drawing
(lower left hand corner). Use a small slot
screwdriver to adjust fan speeds to
compensate for poor pellets or airflow. Turn
the trim pots clockwise to speed up the fan
speed on both Hi and Low settings. A good,
brisk flame that is yellow, not orange, is
what indicates a good burn.
2. The Air Intake Damper control located on
the air intake module (see FIGURE 2)
regulates the amount of combustion air
being fed to the pellet fire pot. For example,
