Automatic Start Up
1. Fines are small pieces of broken pellets (sawdust). Fines do
not ow easily and often build up on the hopper funnel bottom
angles. These nes can be pushed into the feeder opening and
then ll the hopper with pellets. As the system works, they will
be burned.
2. The "TEST" cycle will operate the feed motor for exactly one
minute. Turning to "TEST" again and again may load too much
fuel into the burn pot causing excessive smoke on start-up.
3. The rebox 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 rst re or you are trying different
pellets, set the feed adjuster to #4, Fig. 1. 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 off the front of
the burn pot into the ash pan. Then scrape the holed surface
downward into the burn pot. When the stove feeds, 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. 2.
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 at maximum burn rate and
during normal operation, the ash bed will be larger.
See Note 7.

Horizontal 90° or T: 4.0'
Horizontal 45°: 2.0'
* Long runs of ex or PL vent pipe installed directly vertical from the ue
stub may require more frequent cleaning due to y ash falling off inside
and collecting directly above the combustion blower outlet.
Any use of horizontal venting will require more frequent cleaning. It is the
responsibility of the installer to make sure the entire ue conguration is
accessible for cleaning.

Addendum
Minimizing Smoke During Loss of Power Using Battery Back-up
Harman® strongly recommends installing battery back-up to minimize entry of smoke into the
room 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 and
ofce equipment stores. Your Harman® appliance with Rev E or later software available beginning in
November 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. Your
appliance will pulse the blower every few seconds to clear exhaust until the re is out. NOTE: The UPS
provides 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 re is out and the ESP is still warm, the feeder may restart. Since the re is out, the
ESP temperature will not rise. The unit will then shut-down, and may ash a six-blink status
error. (See ESP error codes)
• If the re is still burning, it will resume normal operation.
Contact your dealer if you have questions about UPS compatibility with your appliance.
Harman® Surere 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 battery
charged when power is available. NOTE: If the power is out for longer than battery life, smoke
leakage 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.

Fuel Specication Details

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. Dierent mixtures of
corn will have distinctively dierent 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 dierent 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 mode
Set feed adjuster to # 3. Set temperature knob to #3, Turn mode selector knob onto “Stove Temp” mode. After the re
has lit, watch that the fuel does not feed too fast that it pushes the red glowing fuel bed o 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 re bed is about ½ to 1 inch from the end of the
burn pot. Settings will vary with dierent types, moisture levels and mix ratios of corn. If you are having diculty burn-
ing a 50% corn / 50% wood pellet mixture, try a lower percentage of corn.
Operation in Room Temp mode
Set feed adjuster to # 2 or # 3. Set temperature knob to desired amount. Turn mode selector knob onto “Room Temp”
mode. After the re has lit, watch that the fuel does not feed too fast that it pushes the red glowing fuel bed o 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 re 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 o 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 dierent types, moisture levels and mix ratios of corn. If you are having diculty burning a 50% corn 50%
wood pellet mixture, try a lower percentage of corn.
Changes to Maintenance Schedule
Wood 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 ll
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.
