ONLY
THIS APPLIANCE NEEDS PERIODIC
INSPECTION AND REPAIR FOR PROPER
OPERATION. CONSULT OWNER’S MANUAL
FOR FURTHER INFORMATION. IT IS
AGAINST FEDERAL REGULATIONS TO
OPERATE THIS APPLIANCE IN A MANNER
INCONSISTENT WITH OPERATING
INSTRUCTIONS IN THE OWNER’S MANUAL
GENERAL INFORMATION
Installation and repair should be done by a qualified
service professional. The stove should be inspected
before use and at least annually by a service
professional. More frequent cleaning may be
required due to fuel quality, excessive lint from
carpeting, bedding material, etc. It is imperative that
control compartments, burn pot and pot holder, and
circulating air passageways of the stove be kept
clean and free of ash buildup, lint, and dust.
The Echo Pellet Heater has been designed and
approved for burning PREMIUM WOOD
PELLETS OF HIGHEST BTU OUTPUT AND
LOWEST % OF ASH CONTENT ONLY.
Burning biomass fuels in other forms or poor
quality pellet fuel is not permitted and will void
your warranty and/or could cause a burn back or
house fire. FOR BEST RESULTS THE WOOD
PELLET FUEL SHOULD BE ¼” DIAMETER
AND APPROXIMATELY 1” LONG.
Store fuel in a covered, dry area. Pellet bags can
absorb moisture and must be kept dry. Never place
bags of fuel next to the heater. Keep fuel away from
combustible materials and moisture. 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 stove while it is in use.
Pellet 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 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 extinguished.
NOTE: During the first few burns (up to 2–4 hours)
the high-temperature paint and sealant used in the
manufacture will emit some odor and smoke. Open
doors and windows to the outside for proper
ventilation during the first burn cycle and the curing
of the paint. SEE INITIAL FIRING PROCESS
beginning on page 15.
Under specific test conditions this heater has been
shown to deliver heat at rates ranging from 16,800
to 26,800 Btu/hr.
This stove must be electrically grounded according
to local codes or, in the absence of local codes, with
the National Electrical Code, ANSI/NFPA 70-
2013.

INSTALLATION
1. When deciding on the location of your heater
and vent pipe, try to 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.
2. Avoid installing heater in high-traffic areas.
Keep children well away from heater when in
operation.
3. A 3-inch clearance to combustibles must be
maintained for horizontal and vertical
venting. When passing through ceilings or
walls, you must use a listed wall thimble,
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.
4. A non-combustible hearth pad must be used if
installed on a carpet, wood floor, or other comb-
ustible material (see Figure 3). Maintain 6”
(152mm) beyond the front and beyond each side
of the fuel loading and ash removal opening.
5. Keep front door of appliance thirty-six (36)
inches from combustibles (drapery, furniture).
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.
7. Install vent at clearances specified by the vent
manufacturer.
8. Exit termination (distance to openings):
a. 3 feet minimum above any forced air
inlet located within 10 feet.
b. 4 feet minimum below and horizontally
or 1 foot minimum above any door,
window, or gravity air inlet into any
building.
c. 2 feet minimum to an adjacent building
and 7 feet minimum above grade when
located adjacent to public walkways.

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 12-
volt power.
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 your
Type "L" pellet vent pipe, you may go
straight out through a wall thimble. You
must connect a pellet vent tee at this point
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 4-inch Type "L" vent pipe is required.
Horizontal runs must be limited to 2 feet. A
wall band is required for every 4 feet
minimum on a vertical run at an exterior
wall.
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.
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.

WALL & REMOTE THERMOSTAT
INSTALLATION FOR ECHO E.I.
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.
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 the wall outlet!
2. Hook up the thermostat wires to terminals (see
Figure 8). Remember to remove copper shunt.
Replace shunt if thermostat hook-up is
disconnected. If a remote thermostat is used you
will have to 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. For the
remote find 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. You have the option to have the thermostat run
the stove either ON/OFF or Hi/Low. Factory
setting is ON/OFF. By changing the Type
setting jumper on the circuit board (see Figure
14), you can switch to the Hi/Low mode. This
should be done in extremely cold climates so the
house will maintain an even temperature and not
be cycling on/off constantly.
6. Please 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.
IMPORTANT: Any electrical work performed on
the Echo should be done by qualified personnel.
Always plug AC cord in before DC battery.
Notice: First Burn is the Most Important
All Thelin Gas, Pellet, and Wood heaters are
finished with high temperature paint that when
properly cured provides years of service. We have
found properly curing the paint during the initial
fire is the single most important factor in preserving
a long term finish.
Based on the initial curing process of 15 to 20
minutes and warming up on Low Setting, the
stove body will heat and begin to cure the paint
as a small amount of smoke is released.
If the unit is not turn off during this initial period
and allowed to cool, the paint may become brittle
and chip after many heat and cool cycles.
Once completed and 24 hours has passed the
first burn should be about 15 minutes long. Start the
unit on “Low” setting and once
the starts to warm shut it off and allow to
completely cool before using.

START-UP AND OPERATION
A. Filling the Hopper and Start-Up
CAUTION: Fuel hopper lid must be closed before
operating the unit. The feed motor will not work if
the hopper lid is open. DO NOT OVERFILL THE
HOPPER! The Echo will hold approximately 50
pounds of pellets.
Open the top cover and fill the hopper with pellets
(see Figure 9).
Use good-quality pellets that give you a vibrant,
yellow flame with little or no soot. Poor quality
pellets will burn rich with black sooty smoke and
ash will accumulate quickly.
IMPORTANT: The quality of pellet varies from
brand to brand. This will affect the efficiency of
your heater. We suggest that you try several brands
until you find one that provides a clean, efficient burn.
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). Light the pellets in the fire pot using any
approved lighting fluid.
B. Lighting Instructions
The Echo E.I. has automatic ignition. As a result
you 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 you should see flame and in
six minutes the igniter will shut off. The LED next
to the button will blink during the six-minute start-
up 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 and you will have to repeat the
process.
NOTE: Pellets do not feed in the “Fan” position.
If you choose to use a wall or remote thermostat
follow the thermostat manufacturers instructions
carefully and make sure you use the built in
thermostat terminals on the bottom of the stove. (See
Figure 8) We recommend you run the heater on
“High” for about 30 minutes to get the heat
exchanger hot before turning it to “Low.” You will
need to burn the heater for a few hours before
deciding which setting is best for your particular
needs.
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. 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.
2. 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.
3. 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.
4. The "Clean" position is to be used only when
the heater is not burning and you wish to clean
out the combustion housing and fan blades. See
the "Hopper Clean Out" section under
"Maintenance Procedures."
5. After the heater is running for several hours and
you wish to turn it off, simply push the button to
"Off." If you use a remote or wall thermostat it
will turn off the stove automatically when the
desired room temperature is reached. The
heater will continue to run until it cools down
and it will then automatically shut down at
58 degrees F. or in 25 minutes, whichever
comes first.
6. REMEMBER: 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.

ECHO PELLET E.I. II PELLET HEATER

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
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.
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
allows you to control the feed rate in each setting—
Low, Med, and High. By turning the button
clockwise you can increase the feed rate in each
setting. By turning the button counter-clockwise
you can decrease the feed rate.
Move this button carefully! It is designed to
fine-tune the heater in each position in the event
you change brands of pellets and/or live at a
higher elevation.
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.
2. The Echo Pellet 12V back-up can be purchased
as an option and includes the following
components:
a. Deep cycle seated 12-volt gel cell battery
(available at most battery stores)
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
on the stove. The red must be plugged in
first before the black.
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. If you hook up the
cables correctly the LED light on the control
panel come on and glow green. If hooked up
improperly, this LED will glow.
WARNING: Make sure the red cable goes to
the red terminal (positive connector) and the
black cable goes to the black terminal (negative
connector).
4. If you decide to purchase your own 12-volt
back-up system, we recommend a sealed gel
cell battery. Failure to install the proper
battery could cause physical harm to you
and/or your property and will also void the
heater warranty.
5. When the battery is properly connected and the
heater plugged in, the following will happen
automatically:
a. The heater will automatically switch to 12-
volt 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

ECHO PELLET E.I. II PELLET HEATER
18
battery attached. Battery will drain
down and fail to recharge.
6. If you choose to separate the battery from the
heater by lengthening the cables, you must make
sure the cable used will carry the current to the
heater. For example, if the distance is 10 to 20
feet, then 12-gauge wire must be used. Check
with your local electrical professional to make
sure you have used the proper gauge wire/cable.
7. The automatic ignition feature will not work on
DC power only. The stove can be lit manually
with an approved starter material. Call Thelin
Hearth Products if you need help with manual
lighting.
MAINTENANCE PROCEDURES
CAUTION: Moving parts may cause injury. DO
NOT operate with rear cover removed.
WARNING: Risk of electrical shock. Disconnect
all power before servicing.
Always turn your 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.
The following procedures should be studied
carefully and performed regularly as indicated.
a. 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.
FIGURE 12
Here are some other maintenance procedures
that should be performed on a regular basis.
b. 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.
c. Vacuum inside stove ash pockets on both
sides of fire pot and heat exchange tubes.

ECHO PELLET E.I. II PELLET HEATER
19
d. 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
around and below the pot should be
checked every five or six days depending
on how many hours a day you are burning
your heater and the quality of the pellets
being burned. After a few days you will be
able to determine the frequency required
for cleaning.
e. Scrape pellet feed chute with putty knife to
remove hardened material on which
sawdust can accumulate.
f. 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 you utilize the “Clean” mode on
the control dial.
g. 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, so you will initially monitor the
buildup in the vent pipe. 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. If
you burn the heater all of the time, you should
do this every eight to ten days.
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. Remember, you must always check the
clean out cap on the tee after utilizing the clean
feature (see Figure 12). (See Figure 16 for
routine stove clean out and maintenance.)
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)
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.
This Echo Pellet Heater has been tested and
approved by Warnock Hersey Test Labs in
Middleton, Wisconsin.
TROUBLESHOOTING
The following scenarios are provided in order to
help you locate a difficulty if the heater performs in a
manner which would seem to indicate a malfunction:
1. Problem: I loaded the heater for start-up, lit the
fire starter and pellets, but the fire did not light.
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. Remember that the timer
on start-up runs about six minutes and if the
pellets have not lit, then you may have to repeat
the start-up sequence. Also, the stove only runs
on one speed until a temperature is reached that
activates the run mode. This usually takes 15 to
20 minutes, and in extremely cold climates, you
might have to repeat the start-up procedure for
the stove to reach this temperature.

ECHO PELLET E.I. II PELLET HEATER
20
2. Problem: The heater was lit and burning properly,
then suddenly it stopped feeding pellets.
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
happens, you must empty the hopper and check
the feed chute to see what is causing the jam.
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. Problem: The fire was burning well and then it
began to overfeed pellets and started backing up
into the pellet feed chute, smothering the fire.
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 you use a low-
grade pellet and clinkers (fused ash and dirt)
form in the bottom of the fire pot and chock the
air intake, you might consider changing the
brand of pellets to one that burns cleaner. You
must let the fire go 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! You must clean the heat exchanger
tubes (see Figure 12) regularly to ensure a good
air to fuel ration, thus allowing the heater to
"breathe" properly. You must also check the tee
and vent pipe to see that they are not clogged
and full of ash.
4. Problem: The heater was burning well and then
soot began forming on the door glass.
Solution: Black soot forming on the door glass
means that the combustion is not right and the
heater needs a good clean out. Some brands of
pellets burn much richer than others and you
might have to change 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, then the heater needs
a good clean out.
5. Problem: We had a power failure and the heater
emitted smoke for about five minutes.
Solution: If the heater emits smoke during a
power failure and you have frequent power
failures, then we suggest you purchase the
battery back-up system. If the vent pipe is
installed according to these instructions, the
smoke will siphon out of the pipe in most
instances.
6. Problem: After several weeks of outstanding
performance, the heater suddenly stopped and
the red light under the control panel came on.
This light is the High Temp/Flue indicator light.
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 case of flue clogging is
a safety feature, and if the shut down occurs it
means you have a problem and should consult a
service technician and/or clean your pipe and
heater thoroughly. If you feel the fly ash build-
up is excessive, we suggest you 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. Keep
this in mind when you store and handle your
pellets. The heater warranty does not cover the
quality of the fuels used or the way they may be
handled, either before or after you've purchased
them. High-wind condition may require a high-
wind cap. See Appendix A.
