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. You can push these fines into the feeder opening and then fill the hopper with pellets. As the system works, they will be burned. Or you can clean them out before filling the hopper.2. The "TEST" cycle will operate the feeder motor for exactly one minute. Turning to "TEST" again and again may purge 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 or the ash pan door are open.4. Adjust Feed Rate. If this is your first fire or you are trying different pellets, set the feed limit to #4, Fig. 17. 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 top surface of the burn pot downward into the base of the burn pot. When the stove is ignited these scrapings will be pushed out by the feeder and burned.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 limit # 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. 18. If the ash line is larger than 1", turn the feed limit 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 at most normal settings the ash bed will be larger.

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.
