E. Fire Characteristics and Flame Height
Adjustment
A properly adjusted fire with the heat output on HIGH
has an active flame pattern that extends out of the firepot
approximately 8 inches (203mm).
If the fire has tall flames with black tails and seems some-
what lazy, the flame height will need to be reduced. If
the fire is not 8 inches (203mm) tall, the flame height will
need to be increased. A medium or low setting will give
a shorter flame.
The flame will rise and fall somewhat. This is normal.
With your appliance in Manual mode and the heat output
level set to HIGH adjust the flame height using the
FLAME HEIGHT ADJUST screen on the thermostat wall
control. Figure 24.1.

F. Battery Back-up System (Optional)
The appliance has been designed to operate on an optional
battery back-up system. If you have frequent power
outages in your region, hook the appliance up to a 12 volt
battery and it will automatically switch to battery power in
the event of a power failure. There will be a battery icon
that appears on your wall control to let you know you are
now operating on battery power.
Once you are operating on battery power, you must
manually light the fire in the appliance as it will no longer
automatically light. Use only approved fire starting gel to
start the fire. The high burn rate is no longer available
on battery back-up as each level drops down one level.
For example; the high burn becomes medium high burn
and so on.
We recommend a 12 volt deep cycle battery, (i.e., marine or
RV type). If the battery charge falls below 10 volt it can no
longer sustain the appliance operation and the appliance
will shut down. A 12 volt battery cable is available through
your local dealer.
• Hook up to battery terminals BEFORE you
plug battery into the appliance.
• Damage to internal electronic components
may occur.
CAUTION
G. Ignition Cycles
The Advanced Energy engine is controlled by the digital wall
control. The digital display on the wall control will tell you what
your appliance is doing in the upper left corner, above the line
Every time the thermostat calls for heat, the appliance steps
through five cycles:
1. Ignition cycle
2. Soft-start cycle
3. Heating cycle
4. Shut down cycle
5. Cleaning cycle
The duration and characteristics of these cycles may be differ-
ent with each type of fuel selected.
1. Start-Up
During this cycle:
• The igniter turns on for 90 seconds to heat up the air in
the firepot
• The combustion blower starts
• Vacuum switch comes on
• Feed motor turns on adding fuel to the firepot and the
appliance waits for the fire to start
The duration of start-up depends on the type and quality of fuel
used. It is normal to see some smoke during the ignition pro-
cess as moisture evaporates and the fuel lights. The smoke
will stop once the fire starts.
If you are lighting your appliance for the first time the feed tube
is empty and it can take some time to fill it with fuel before you
will see a fire. To speed up this process, put a handful of fuel
in the firepot. You can also do this when you have run your
hopper dry.
2. SS-Low / SS-Med (Slow-Start Low, Slow-Start Medium)
Once the fire is lit, the appliance moves into the low soft-start
cycle as it continues to build the fire. In this cycle, more fuel
will be added. As the fire builds, the appliance will change to
medium soft-start mode and the heating cycle begins.
3. Auto / Man - L, ML, M, MH, H
There are two choices in the Automatic / Manual menu of how
your appliance will operate.
In Automatic Mode, the wall control will turn the heat output
level up or down depending on how far the room temperature
is from the desired temperature. The digital display will read
AUTO:M as an example of automatic, medium level.
As the room temperature approaches the desired tempera-
ture, the appliance will turn down to lower settings. When you
change the appliance to Manual, set the heat output setting
from the main screen. The right bottom button will read HEAT
OUTPUT.
