• The
fi rst three or four fi res should be of moderate size to
allow the oils and binders to be burned from the fi replace 
and the refractory and paint to cure. You may notice 
an industrial odor the fi rst few fi res. This is considered 
normal.
• Use well-seasoned wood.
• Open 
the
fl ue damper to a fully open position.
• Place crumpled or twisted paper under the fi replace
grate.
• Loosely arrange kindling or small pieces of wood to form
a ‘tent’ on the fi replace grate.
• Pre-warm
the
fl ue to establish a draft to help reduce
smoke spillage during start-up. Hold a rolled up piece 
of burning newspaper under the fl ue damper for a few 
moments.
• Light the crumpled paper to ignite the kindling.
• Add small pieces of wood until a hot bed of embers has 
been established.
• Add a minimum of three average size pieces of split
fi rewood, placed to allow combustion air and fl ames 
between them.
C. Starting a Fire
NOTICE: You must establish a good draft to prevent smoke 
spillage into the room.
WARNING! Risk of Fire! Keep combustible materials, 
gasoline and other fl ammable vapors and liquids clear of 
the fi replace.
DO NOT:
• store 
fl ammable materials close to the fi replace
• use gasoline, lantern fuel, kerosene, charcoal lighter
fl uid or similar liquids to start or “freshen up” a fi re in this 
fi replace.
Keep all fl ammable liquids well away from the fi replace while 
it is in use. Combustible materials may ignite.
B. Seasoned Wood
Properly seasoned wood is important for successful 
operation of your fi replace. Most woodburning fi replace 
problems are caused by burning wet, unseasoned wood.
Seasoned fi rewood is wood that is cut to size, split and air 
dried to a moisture content of around 20%. 
Imagine a wooden bucket that weighs about eight 
pounds. Fill it with a gallon of water, put it in the fi replace 
and try to burn it. This sounds ridiculous but that is exactly 
what you are doing if you burn unseasoned wood.
A tree cut down a year ago and not split is likely to have 
almost as high a moisture content now as it did when it 
was cut.
Please refer to Section 2.M. for more detail.
CAUTION!
Odors and vapors released during initial
operation may be irritating to sensitive individuals. 
Open windows for air circulation.
D. Grate
This fi replace is designed to be used with the grate sup-
plied with this unit or one approved by HHT. The grate will 
break down over time and will need occasional replace-
ment.
WARNING! Risk of Fire! Use only the factory-supplied 
integral grate.
• Keeps logs in place.
• Allows proper air circulation around the fi re.
E. Firescreen
The fi rescreen is provided to control sparks. Keep it 
closed when the fi replace is in use.
WARNING! Risk of Fire or Burns! 
• Screen will not prevent burning materials from falling 
out.
• Screen pulls or handles may be hot.
F. Flue Damper
• Refer to Figure 2.1 for location of control.
• Must be in fully open position (handle up toward the top 
of the fi replace) during operation of the fi replace.
• Before
lighting
the
fi replace, verify fully open position by
looking up from the inside of the fi replace.
WARNING! Risk of Fire and Asphyxiation! Open 
damper prior to operating fi replace. A closed damper 
overfi res the fi replace and spills smoke and fl ames 
into the room.
G. Refractory
• The refractory is supplied to contain heat and provide
an attractive interior.
• It will break down over time and will need occasional
replacement. Small hairline cracks and discoloration are 
normal and do not affect its safety. 
• (See refractory maintenance Section 3.C.)
WARNING! Risk of Fire! DO NOT burn fi replace with-
out refractory. Use only refractory supplied by Hearth & 
Home Technologies, Inc.
