MAINTENANCE PROCEDURES
CAUTION: Moving parts may cause injury. DO
OT operate with rear cover removed.
WARNING: Risk of electrical shock. Disconnect
all power before servicing.
Always tur your heater off a d let it cool before
clea i g.
FIGURE 12
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 eed 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.
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.
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 Clea 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. Clea i g the Exhaust Fa Blade & Heat
Excha ger: 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
routi e stove clea out a d mai te a ce.)
3. Clea i g the Fa 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. Keepi g the Glass Clea : 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.
Solutio : 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.
2. Problem: The heater was lit and burning properly,
then suddenly it stopped feeding pellets.
Solutio : 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. CAUTIO : 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.
Solutio : 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. ever 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.
Solutio : 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.
Solutio : 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.
Solutio : 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.
7. Problem: I turned off the switch and the heater
continued running.
Solutio : 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."
Solutio : Fan motor brushes are wearing out.
Brushes in fan motor need to be replaced.
Contact your dealer or call factory for
replacement brushes.
9. Problem: Stove shuts off at night when running
on low.
Solutio : Feed is to low. Adjust feed trim
button (turn clockwise) until feed can maintain
fire.
10. Problem: I see a flashing green light behind the
outer shield. What does this mean?
Solutio : The flashing green light behind the
outer shield means the circuit board is
energized. This is okay. “Green means go.” All
systems are ready and operational.
