C. Loss of Power
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
combustionblowertoremoveexhaust.Apowerfailurewill
cause the combustion blower to stop. This may lead to
exhaustseepingintotheroom.Verticalriseintheventing
may provide natural draft. It is, however, no guarantee
againstleakage.
There are two Harman® approved battery back-up
options for your appliance:
Uninterruptible Power Supply UPSbatteryback-upsare
availableonlineoratcomputerandofceequipmentstores.
Your Harman® appliance with Rev E or later software
available beginning in November 2010 may be plugged
directlyintoaHarman®approvedUPS:
