F. Helpful Hints
When operating your Harman
®
Absolute63 Pellet Stove,
follow basic safety standards. Read these instructions
carefully before you attempt to operate the Absolute63 Pellet
Stove. Failure to do so may result in damage to property or
personal injury and may void the product warranty.
Cleaning Burn Pot:
Whenever your stove is not burning,
take the opportunity to scrape the burn pot to remove carbon
buildup. A vacuum cleaner is handy to remove the residue.
Be sure the stove is cold if you use a vacuum.
Carbon buildup can be scraped loose with the fire burning
using the special tool provided with your stove. Scrape the
floor and sides of the burn pot. The carbon will be pushed
out by the incoming fuel. Always wear gloves when scraping
the burnpot.
Disposal of Ashes
: Ashes should be placed in a steel
container with a tight fitting lid. The closed container of
ashes should be placed on a non-combustible floor or on the
ground, well away from all combustible materials, pending
final disposal. If the ashes are disposed of by burial in soil or
otherwise locally dispersed, they should be retained in the
closed container until all cinders have thoroughly cooled.
Other waste shall not be placed in this container.
Soot and Flyash Formation and Need for Removal
: The
products of combustion will contain small particles of flyash.
The flyash will collect in the exhaust venting system and
restrict the flow of the flue gases. Incomplete combustion,
such as occurs during startup, shutdown, or incorrect
operation of the room heater will lead to some soot formation
which will collect in the exhaust venting system. The exhaust
venting system should be inspected at least once every year
to determine if cleaning is necessary.
When burning wood pellets on low, the potential exists for
creosote to form. The venting system should be inspected
periodically throughout the heating season to determine
if creosote buildup has occurred. If a significant layer of
creosote has accumulated (1/8” or more), it should be
removed to reduce the risk of a chimney fire. If a fire occurs,
call the fire department, shut down the stove, and evacuate
the residence. Before using the appliance, have the venting
system thoroughly inspected and replace any damaged
components.
With any hearth appliance, installation of smoke detectors
is recommended on every level of the home.
Possible causes of smoke detector activation:
Paint curing process - Open a window near the appliance
for the first few hours of burning.
Exhaust being drawn back inside the dwelling - Outside air
connection to the appliance is necessary.
Vent leakage - All interior seams and joints should be sealed
with silicone where applicable. Follow vent manufacturers
instructions for proper sealing.
CAUTION
!
This appliance must be vented to the outside
G. Fuel Specifications
The Absolute63 Pellet Stove is approved for burning any
grade of pelletized bio-mass fuel.
It should be noted, that higher ash content fuel will require
more frequent cleaning.
The moisture content of pellets must not exceed 8%. Higher
moisture will rob BTU’s and may not burn properly.
Fuel should
not
be stored within the stove installation
clearances or within the space required for cleaning and
ash removal.
Fuel and Fuel Storage
Pellet fuel quality can fluctuate from manufacturer to
manufacturer, and even from bag to bag.
Hearth & Home Technologies recommends using only fuel
that is certified by the Pellet Fuels Institute (PFI).
Fuel Material
•
Made from sawdust and/or other wood by-products.
• Source material typically determines ash content.
Higher Ash Content Material
• Hardwoods with high mineral content.
• Bark and leaves as source material.
• “Standard” grade pellets and other biomass.
Lower Ash Content Material
•
Softwood; pine, fir, etc.
• Materials with lower mineral content.
• “Premium” grade pellets.
Performance
• Higher ash content requires more frequent maintenance.
• “Premium” grade pellets will produce the highest heat
output.
•
Burning pellets longer than 1-1/2 inches (38mm) can
cause inconsistent feeding and/or ignition.
Clinkers
• Minerals and other non-combustible materials, like sand,
will turn into a hard glass-like substance when heated.
• Trees from different areas will vary in mineral content.
For this reason, some fuels will produce more clinkers
than others.
Moisture
• Always burn dry fuel. Burning fuel with high moisture
content takes energy to dry and tends to cool the
appliance thus, robbing heat from your home.
• Damp pellet fuel could turn back into sawdust which
does not flow properly through the feed system.
