Operating Instructions
A. Fuel Size And Material
1. Wood Pellets
Wood pellets are made from sawdust or wood by-products. If
the source material is hardwood, they can have a higher mineral
content, creating more ash. Fuels containing bark will also have
higher ash content. Minerals and other non-combustible materials
such as sand will turn into a hard, glass-like substance called
a clinker when heated to the extreme temperatures our fi repot
reaches. This is what forms clinkers in the bottom of the fi repot.
Trees from different areas will vary in mineral content. That is
why some fuels produce more clinkers than others. Pellets are
manufactured in either 1/4 inch or 5/16 inch (6-8mm) diameter and
should be no more than 1-1/2 inches (38mm) in length. Pellet
lengths may even vary by lot from the same manufacturer which
is why the feed rate may need to be adjusted occasionally. If you
burn pellets longer than 1-1/2 inches (38mm) you may have
an inconsistent fuel feed rate and/or missed ignitions.
Pellet fuel quality can greatly fl uctuate.
The Advanced Energy
(AE) appliance has been designed to burn a wide variety
of fuels, giving you the choice to use the fuel that is most
economical in your region. Premium wood pellets have the
lowest ash content, under 1%. Standard grade pellet, high
ash pellets, corn and other biomass fuels all have higher
ash content. The higher the ash content, the more often the
ash pan will need to be emptied. Premium wood pellets will
produce the least ash and tends to produce the highest heat
output.
Always burn dry fuel. Burning fuel with high moisture content
takes heat from the fuel and tends to cool the appliance, robbing
heat from your home. Damp pellet fuel can clog the feed
system.
We recommend that you buy fuel in multi-ton lots whenever
possible. However, we do recommend trying various brands
before purchasing multi-ton lots to ensure your satisfaction.
2. Other Fuels
This appliance has been tested and approved by Hearth &
Home Technologies for shelled fi eld corn, wheat and black
oil sunfl ower seeds. When changing to a different fuel, be
sure to empty the hopper of the previous fuel and vacuum
the hopper before you fi ll it with the new fuel. Make the
appropriate selection on the FUEL SELECTION screen on the
thermostat wall control. The burn rate, BTU content and heat
output will all vary depending on fuel selected. See Figure
22.1 on page 22.
NOTE: If you are burning a high ash fuel set the fuel
selection “Wd Pellet-Util”.
When purchasing corn or wheat to burn in your appliance,
read the ingredient label very carefully. Do NOT purchase
fuels that contains any additives such as oil and meals
as they will cause poor unit performance.
B. General Operating Information
1. Thermostat Wall Control - Automatic Setting
The appliance is like most modern furnaces; when the
thermostat wall control calls for heat, your appliance will
automatically light and deliver heat. When the room is up to
temperature and the wall control is satisfi ed the appliance
will shut down. In the automatic setting the heat output
level is controlled by the wall control. Select “Automatic”
on the AUTO/MANUAL screen. Figure 21.1.
3. Auto Clean Firepot System
Your appliance is equipped with an automatic fi repot
cleaning system that will change the frequency of cleaning
based on the fuel being burned.
The auto clean system will clean itself immediately on
initial plug in. If there is a power outage, as soon as power
is restored it will automatically clean itself.
Tested and approved for wood pellets, shelled fi eld
corn, wheat and black oil sunfl ower seeds. Burning
of any other type of fuel voids your warranty.

See Thermostat Wall Control Manual
for detailed operating instructions.
2. Thermostat Wall Control - Manual Setting
When you select “Manual” on the AUTO/MANUAL
screen the appliance will still automatically turn on and
off according to the temperature setting. However, you
will be able to manually control the heat output levels.
Adjust the heat output levels by using the Heat Output
Level screen. Figure 21.2.
