required.
Automatic Start up
helpful hints1. Fines are small pieces of broken pellets
(sawdust). Fines do
not flow easily and often build up on the hopper funnel bottom
angles. These fines can be pushed into the feeder opening and then
fill the hopper with pellets. As the system works, they will be
burned.
2. The "TEST" cycle will operate the feeder motor for exactly
one minute. Turning to "TEST" again and again may feed too much
fuel into the burn pot causing excessive smoke on start-up.
3. The firebox low pressure switch will not allow the auger
motor or the igniter element to operate if the view door is
open.
4. Adjust Feed Rate. If this is your first fire or you are
trying different pellets, set the feed adjuster to #4, Fig. 3. This
is a conservative number and will probably need to be increased.
After you know a feed rate setting that works well, use that
setting. Remember, if your feed rate is too high you may waste
fuel.
5. This is usually a weekly maintenance procedure. Cleaning the
burn pot with the scraper with a small amount of new fuel in the
bottom is not a problem. First, scrape the ashes on the front of
the burn pot into the ash pan. Then scrape the holed surface
downward into the burn pot. When the stove is ignited these
scrapings will be pushed out by the feeder.
6. The ash pan can hold the ashes from approximately 1 ton of
premium fuel. This means the ashes will only need to be emptied a
few times a year.
7. Setting the feed adjuster # for maximum burn: With the unit
burning in "AUTO", turn to "Stove Mode" and put the fan on "H". Set
the Temperature Dial to #7. Allow the unit to burn for about 30
minutes and check ash on front of burn pot. Fig. 4. If the ash line
is larger than 1", turn the feed adjuster from #4 to #5. Allow
another 30 minutes of burn time and check again. If , at #6
setting, a 1" or less ash bed is not obtainable, it is not a
problem. The 1" ash bed is only a maximum burn rate and at most
normal settings the ash bed will be larger.

Creosote - Formation and Need for removal
-Whenwoodisburnedslowly,itproducestarandotherorganicvapors,whichcombinewithexpelledmoisturetoformcreosote.Thecreosote

and Flyash: Formation and Need for removal- The products of
combustion will contain small particles of flyash. The flyash will
collect in the exhaust venting system and restrict the flow of flue
gases. Incomplete combustion, such as occurs during start-up,
shut-down, 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.

Harman pellet burning, free-standing stoves and inserts have
been tested to ASTM E1509 for burning shelled corn in a mixture
with wood pellets. The listing approves up to a 50% corn and 50%
pellet mixture. Different mixtures of corn will have distinctively
different burn characteristics depending upon moisture content and
variety. The operator should closely monitor the stove’s operation
when burning a new corn/pellet mixture or a different variety of
corn, and make any necessary adjustments to feed rate. Since corn
is typically higher in ash and moisture content, cleaning and ash
removal will be needed more frequently.
Operation in Stove Temp modeSet feed adjuster to # 3. Set
temperature knob to #3, Turn mode selector knob onto “Stove Temp”
mode. After the fire has lit, watch that the fuel does not feed too
fast that it pushes the red glowing fuel bed off of the burn pot
grate. If it does, lower the feed adjuster setting or use a lower
percentage of corn in the mixture. After the stove has burned for
10 minutes and the entire fuel bed is burning, the feed adjuster
and temperature knobs may be adjusted for higher heat output if
desired. Maximum feed has been reached when the fire bed is about ½
to 1 inch from the end of the burn pot. Settings will vary with
different types, moisture levels and mix ratios of corn. If you are
having difficulty burn-ing a 50% corn / 50% wood pellet mixture,
try a lower percentage of corn.
Operation in Room Temp modeSet feed adjuster to # 2 or # 3. Set
temperature knob to desired amount. Turn mode selector knob onto
“Room Temp” mode. After the fire has lit, watch that the fuel does
not feed too fast that it pushes the red glowing fuel bed off of
the burn pot grate. After the stove has burned for 10 minutes and
the entire fuel bed is burning, the feed adjuster may be set to a
higher output level if desired. Maximum feed has been reached when
the fire bed is about ½ to 1 inch from the end of the burn pot. It
is recommended that after burning at the desired settings, turn the
stove off and allow it to cool, then turn it back on in “Room Temp”
mode and watch the stove restart and verify correct operation.
Settings will vary with different types, moisture levels and mix
ratios of corn. If you are having difficulty burning a 50% corn 50%
wood pellet mixture, try a lower percentage of corn.
Changes to Maintenance ScheduleWood pellets average around 6%
moisture content or less. Corn will be 14 or 15% moisture. With
more moisture in the fuel, more maintenance will be incurred. Burn
pot scraping may need to be done once per day. The ash pan will
fill more quickly and may need emptied weekly. Most importantly,
remove the burn pot cleanout cover weekly to clean the air passage
and the igniter element. Excessive buildup on the igniter may lead
to shortened igniter life.
Venting Consideration: Check with your venting manufacturer
regarding possible exclusions when a mixture of corn and pellets is
burned.
Addendum for Burning Corn and Pellet Fuel Mixture
Loosen these two wing screws for access to clean the air passage
and igniter.
* For P38+ model, follow Stove Temp instructions. Keep feed rate
on #3 or above when using a wall thermostat.

AddendumMinimizing Smoke During Loss of Power Using Battery
Back-up
Harman® strongly recommends installing battery back-up to
minimize entry of smoke into theroom in the event of power
loss.
Your pellet/biomass burning appliance relies on a combustion
blower to remove exhaust. A power failure will cause the combustion
blower to stop. This may lead to exhaust seeping into the room.
Vertical rise in the venting may provide natural draft. It is,
however, no guarantee against leakage.
There are two Harman® approved battery back-up options for your
appliance:
Uninterruptible Power Supply (UPS) UPS battery back-ups are
available online or at computer andoffice equipment stores. Your
Harman® appliance with Rev E or later software available beginning
inNovember 2010 may be plugged directly into a Harman® approved
UPS:
• The APC (American Power Conversion) model #BE750G and the
TrippLite model INTERNET750U are tested and approved. Other brands
or models may not be compatible.
When power is lost, a fully charged UPS will power a safe,
combustion blower only shut-down. Yourappliance will pulse the
blower every few seconds to clear exhaust until the fire is out.
NOTE: The UPSprovides safe shut-down only. It is not intended for
continued operation.
Your appliance will recognize when power is restored. What
happens depends on ESP temperature and whether it is equipped with
automatic ignition:
• In “Automatic” setting, units equipped with automatic ignition
will respond to the set point and ESP temperature and resume normal
operation.
• In “Manual” setting or for units without automatic ignition:•
If the ESP is cool, the appliance will remain shut down.• If the
fire is out and the ESP is still warm, the feeder may restart.
Since the fire is out, the
ESP temperature will not rise. The unit will then shut-down, and
may flash a six-blink status error. (See ESP error codes)
• If the fire is still burning, it will resume normal
operation.
Contact your dealer if you have questions about UPS
compatibility with your appliance.
Harman® Surefire 512H Battery Back-up The 512H connects to a 12
volt deep cycle battery that will run your appliance for up to
eight (8) hours. It includes a trickle charge feature that keeps
your batterycharged when power is available. NOTE: If the power is
out for longer than battery life, smokeleakage may still occur
unless your stove has been safely shut down.
CAUTION! Always keep appliance doors and hopper lid closed and
latched during operation and during power failures to minimize risk
of smoke or burn-back.
CAUTION! Use only Harman® approved battery back-up devices.
Other products may not operate properly, can create unsafe
conditions or damage your appliance.
