EI Pellet Heater Repair Manual 3
INTRODUCTION & SERVICE
PHILOSOPHY
The following is a comprehensive service
manual which will assist both the dealer or
service personnel in maintaining and
servicing the Parlour and Gnome Pellet
Stoves.
Before getting into the specifics of service,
we would like to give an overview of our
service philosophy and what we expect of
dealers when they take on the Thelin line.
To become a pellet stove dealer means by
definition, that you will be making a
commitment to service. This is an
appliance—not another wood stove. If you
are not prepared to enter into the appliance
repair and service business, then you should
not consider becoming a pellet stove dealer.
Pellet stoves, for the most part, are
wonderful heaters that will, with proper
maintenance, provide years of clean,
trouble-free burning and quality heat. The
simple fact is they have many moving parts,
unlike a wood stove, and these parts require
lubrication and maintenance. Because the
pellet technology is new, the user must be
educated and trained as to the proper use and
maintenance from season to season to avoid
performance problems. For these reasons we
require our dealers set up a service
department that is dedicated to keeping the
customer happy with a care-free unit. The
user must be made aware of his or her
responsibilities and what is required to keep
the unit working at peak performance. The
service department and personnel should
adhere to the following guidelines:
1. When a customer calls for service they
should be greeted with a friendly,
calming voice, assuring them that the
problem will be given prompt attention.
It is important to get and give accurate,
relevant information. The following
information is a guideline:
•Customer’s name, address, and
phone number.
•Serial number of the stove.
•What the customer thinks is wrong.
•When did the problem start?
•When was the unit last serviced?
•When and where was the stove
purchased?
•Who installed the unit, when, and
how is it vented?
Note: At this point, the problem can
usually be dealt with by phone. Ninety
percent of pellet stove problems are lack
of cleaning.
2. Service personnel should possess a high
degree of mechanical aptitude, good
common sense couple with an analytical
mind. The ability to read and use
electrical schematics, listen to customer
complaints politely and determine what
might be causing the difficulty. The
customer needs to feel confident that the
service person will be able to detect
system malfunctions accurately, analyze
problems, and solve them.
3. When entering the customer’s home the
service person should be neat and clean
in appearance, have the necessary tools
and parts required to attend to the
problem and share with the customer an
explanation of charges and the
customer’s responsibilities in regard to
future maintenance. This must be done
in such a manner that there is no
misunderstanding or ill feeling.

4. Remember, it is the service person who
represents your business when in the
customer’s home. A good impression by
the service person creates a good
impression of your business. The work is
expected to be neat and professionally
done.
5. If you need to schedule a service call,
remember the following: Prioritize calls
so “no heat” calls are taken care of first.
Do minor calls next but don’t put them
off or you will only have an angry, upset
customer who will cause a lot of grief
for you and your business. Stick to your
schedule. If you tell a customer you will
be there tomorrow at 2:00 p.m., be there
or call well in advance to let them know.
Their time is valuable also. If a part is
needed and you don’t have it, tell them
and order one as soon as you get back to
the store. Give honest responses, not
creative excuses.
6. Once on the job the service person must
use a systematic approach and think in
terms of cause and effect. After some
experience with the stove, you should be
able to look at the fire, flame pattern,
sounds, and smells and detect problems
immediately. To obtain this degree of
expertise, you must acquaint yourself
with every component and stove
function. Never guess.
TOOLS AND SERVICE KIT
The tools and equipment needed for
servicing the Parlour and Gnome Pellet
Stoves are as follows:
•Good shop vacuum with blower capabilities
•Set of socket drivers which must
included 3/8, 11/32, 1/2, and 7/16
sockets or nut drivers and T-30 to RX

SERVICE CALLS
The objective when making a service call is
to get the customer up and running as
quickly as possible. For this reason the best
method of attack is to find the problem
quickly and isolate the faulty component and
swap it out with the good component in your
dealer service kit. The defective module or
part can then be repaired and returned to the
factory away from the customer’s home.
With this objective in mind, the
troubleshooting can be divided into six (6)
general categories.
1. The fan and feed motors
2. The main circuit board
3. The switch (control knob)
4. The temperature sensors T-1 and T-2
5. The AC power line components
6. The wiring harness and connectors
thereto
These six (6) areas represent the areas where
a problem might occur. They are listed in
the order of highest probability, based on
their history and level of complexity. The
design of the electronics has been done with
reliability as the highest priority, and the
components that are under the most
electrical or thermal stress are very
conservatively rated.
The main board has been listed second, due
to the large number of parts which increases
its chance of failure on a statistical basis. In
practice, however, it should be the most
reliable, due to the rigorous test procedure
each board goes through before being
installed on the stoves. Because of this,
mechanical items, such as the motors,
should be suspected first. Remember, ninety
percent (90%) of pellet stove failures are
due to improper maintenance by the end
user. Check the stove for cleanliness and
routine maintenance before doing any
mechanical service work.
Following is a list of complaints and/or
service problems that represent at least 95%
of possible service calls. Use the FTM80 to
test component failure.
1. Stove not running at all.
2. Feed motor runs, but no fan.
3. Fan motor runs, but no feed.
4. Stove runs, but shuts down about 10
minutes after start up.
5. Stove runs, but keeps shutting down
with over-temp (red) LED coming on.
6. Stove runs, but heat output remains at
the LOW level, even when the control
knob is on HIGH.
7. Stove does not run on battery or battery
does not charge.
8. Stove runs on FAN position but when
switched to LOW, MED, or HIGH, shuts
off immediately.
9. Stove seems to be running on HIGH or
on CLEAN mode at all times.
10. Fan speed seems normal for each
position, but feed rate seems excessive
even on LOW.
11. Stove is running fine and then shuts off
for no apparent reason.
12. Fan speed erratic (surges).
13. Igniter does not run.
