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
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
battery back-ups are
available online or at computer and office 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 fire is out.
NOTE: The UPS provides safe shut-down
only. It is not intended for continued operation.
• The Surefire 512 (available online) 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.
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 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.
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.
D. Emergency Manual Ignition
Harman
®
pellet stoves and inserts should be lit using the
automatic ignition system. This is the safest and most
reliable way for igniting the unit. In the event the automatic
igniter is not functioning, the steps below may be followed
to manually light the stove or insert in the “Constant Burn”
mode. Manual lighting is for emergency purposes only,
and the igniter should be repaired or replaced as soon as
practical.
WARNING
!
Only use firestarter commercially marketed for pellet
stoves and inserts, including wax coated wood chips,
pellet starter gel and pellet igniter blocks. Use of any
other type of firestarter is prohibited.
To avoid serious injury or death read and follow
manufacturer’s warning and instructions for use of firestarter.
Use of firestarter is only permitted when performing a cold
start.
Never attempt to manually light a stove or insert that has
been operated recently and is not at room temperature.
If automatic ignition was attempted, be sure to give the
stove or insert at least 30 minutes or longer to cool to room
temperature.
Be sure that the stove or insert is in the “Igniter - Disabled”
mode of operation.
Once all the precautions have been taken, follow these
steps:
1. On the touch control, select the Burn Mode icon then
select “Constant Burn”.
2. Arrow back and select the Igniter icon then select “Manual”
for the ignition method. Select the Home Icon to go back
to the Main Menu.
3. Fill burn pot with pellets, only half way. (Do Not Over Fill).
4. Add firestarter to pellets following manufacturer’s
instructions.
5. Light pellet gel with a match, and close the door, touch
the On/Off icon on the home screen. Operation will begin
when the fire reaches the proper temperature.
