C. Loss of Power
Harman pellet burning appliances rely on a combustion
blowertoremoveexhaustfromtherebox.Apowerfailure
will cause the combustion blower to stop running, which
mayleadtoexhaustseepageintotheroom.Verticalrisein
the venting system can help create natural draft, which may
reducethelikelihoodofexhaustleakageintothehome.
Installationofalow-costuninterruptiblepowersupply(UPS)
or battery backup system can help ensure the units shuts
down without any minor smoke leakage into the home.
Harman recommends the installation of one of these two
systems for areas prone to power outages.
There is one Harman® approved UPS option for your
appliance:
Uninterruptible Power Supply UPSbatteryback-upsare
availableonlineoratcomputerando󰀩ce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:
• TrippLite model INTERNET750U is 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.
• A Inverter/Charger 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.
For an approved Inverter/Charger refer to www.
harmanstoves.com.
Yourappliancewillrecognizewhenpowerisrestored.What
happens depends on ESP temperature and whether it is
equipped with automatic ignition:
• In “Automatic” Mode, units equipped with automatic
ignitionwillrespondtothesetpointandESPtemperature
and resume normal operation.
• In “Idle” Mode, 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.
IMPORTANT! :UPSorBatteryBackupcannotpreventsmoke
leakage from an improperly maintained unit. Keep the venting
system clean and free from obstructions and maintain all
gaskets to keep an airtight seal.
Use only Harman
®
approved battery back-up devices.
Other products may not operate properly, can create
unsafe conditions or damage your appliance.
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.
