B. Fire Safety
To provide reasonable re safety, the following should be
given serious consideration:
1. Install at least one smoke detector on each oor of
your home to ensure your safety. They should be
located away from the heating appliance and close
to the sleeping areas. Follow the smoke detector
manufacturer’s placement and installation instructions,
and be sure to maintain regularly.
2. A conveniently located Class A re extinguisher.
. A practiced evacuation plan, consisting of at least two
escape routes.
4. In the event of a chimney re:
a. Prepare occupants for immediate evacuation
b. Notify re department
D. Combustible/Non-combustible Materials
• Combustible Material
Material made of or surfaced with wood, compressed
paper, plant bers, plastics, or any material capable
of igniting and burning, whether ame-proofed or not,
plastered or unplastered.
• Non-combustible Material
Material which will not ignite and burn. Such materials are
those consisting entirely of steel, iron, brick, tile, slate,
glass or plasters, or any combination thereof.
• Non-combustible Sealant Material
Sealants which will not ignite and burn: Rutland, Inc.
Fireplace Mortar #6, Rutland 76R, Nuflex 04, GE
RTV106 or GE RTB116 (or equivalent).
E. Seasoned Wood
Burn only dry seasoned wood.
• Store wood under cover, out of the rain and snow.
• Dry and well-seasoned wood will not only minimize the
chance of creosote formation, but will give you the most
efcient re.
• Even dry wood contains at least 15% moisture by weight,
and should be burned hot enough to keep the chimney
hot for as long as it takes to dry the wood out - about one
hour.
• It is a waste of energy to burn unseasoned wood of any
kind.
Dead wood lying on the forest oor should be considered wet,
and requires full seasoning time.
• Standing dead wood can be considered to be about 2/
seasoned.
• To tell if wood is dry enough to burn, check the ends of
the logs.
• If there are cracks radiating in all directions from the center,
it is dry.
• If your wood sizzles in the re, even though the surface
is dry, it may not be fully cured.
C. Overring
Do not over-re.
Over-ring may ignite creosote or will damage
the stove and chimney.
To prevent over-ring your stove, DO NOT:
• Use ammable liquids
• Overload with wood
• Burn trash or large amounts of scrap lumber
• Permit too much air to the re
• Use of processed solid fuel re logs
WARNING
Fire Risk
Symptoms of over-ring may include one or more of the
following:
• Chimney connector or appliance glowing
• Roaring, rumbling noises
• Loud cracking or banging sounds
• Metal warping
• Chimney re
1. Symptoms of Over-Firing
2. What To Do if Your Stove is Over-Firing
• Immediately close the door and air controls to reduce
air supply to the re.
• If you suspect a chimney re, call the re department
and evacuate your house.
• Contact your local chimney professional and have
your stove and stove pipe inspected for any damage.
• Do not use your stove until the chimney professional
informs you it is safe to do so.
Hearth & Home Technologies WILL NOT warranty stoves
that exhibit evidence of over-ring. Evidence of over-ring
includes, but is not limited to:
• Warped air tube
• Deteriorated refractory brick retainers
• Deteriorated bafe and other interior components

F. Burning Process
In recent years there has been an increasing concern about
air quality. Much of the blame for poor air quality has been
placed on the burning of wood for home heating.
In order to improve the situation, we at Quadra-Fire have
developed cleaner-burning wood appliances that surpass
the requirements for emissions established by our governing
agencies.
These wood appliances must be properly operated in order
to ensure that they perform the way they are designed to
perform.
1. Kindling or First Stage
It helps to know a little about the actual process of burning in
order to understand what goes on inside the appliance. The
rst stage of burning is called the kindling stage.
In this stage:
• Wood is heated to a temperature high enough to evapo-
rate the moisture present in all wood.
• Wood will reach the boiling point of water (212°F) and will
not get any hotter until the water is evaporated.
This process takes heat from the coals and tends to cool the
appliance.
Fire requires three things to burn:
• Fuel
• Air
• Heat
If heat is robbed from the appliance during the drying stage,
the new load of wood has reduced the chances for a good
clean burn.
It is always best to burn dry, seasoned rewood. When the
wood isn’t dry, you must open the air controls and burn at a
high burn setting for a longer time to start it burning.
The heat generated from the re should be warming your
home and establishing the ue draft, not evaporating the
moisture out of wet, unseasoned wood, resulting in wasted
heat.
2. Second Stage
In the secondary stage wood gives off ammable gases which
burn above the fuel with bright ames.
During this stage of burning:
• The ames must be maintained and not allowed to go out
to ensure the cleanest possible re.
• If the ames tend to go out, it is set too low for your burn-
ing conditions.
The air control located at the upper right hand corner is used to
adjust for burn rates. This is called the Burn Rate Air Control.
Figure 10.1 on page 10.
3. Final Stage
The nal stage of burning is the charcoal stage. This occurs
when the ammable gases have been mostly burned and
only charcoal remains. This is a naturally clean portion of
the burn. The coals burn with hot blue ames.
• It is very important to reload your appliance while enough
lively hot coals remain in order to provide the amount of
heat needed to dry and rekindle the next load of wood.
• It is best to open the Burn Rate Air and Start-Up Air Con-
trols before reloading. This livens up the coalbed and
reduces excessive emissions (opacity/smoke).
• Open door slowly so that ash or smoke does not exit ap-
pliance through opening.
• Break up any large chunks and distribute the coals so
that the new wood is laid on hot coals.
Air quality is important to all of us, and if we choose to use
wood to heat our homes we should do so responsibly.
We need to learn to burn in the cleanest way possible al-
lowing us to continue using our wood appliances for many
years to come.
NOTICE: Improper operation can turn any wood appli-
ance into a smoldering environmental hazard.

H. Air Controls
1. Start-Up Air Control
The Start-Up Air Control has two primary functions.
The rst function is to activate the Automatic Combustion
Control system (ACC).
• Push the Start-Up Air Control all the way back until it stops
and then pull forward to the front of the appliance until it
stops. Figure 10.1.
• The front air channel opens and allows air to enter the front
of the appliance for approximately 20-24 minutes.
• The front air channel gradually shuts down until it is com-
pletely closed at the end of the 20-24 minutes.
• The re is now controlled by the air supplied by the Burn
Rate Air Control. Figure 10.1.
• This function should be performed each time you reload
the appliance.
The second function of the Start-Up Air Control is operation
of the rear air system.
• Push the Start-Up Air Control /8 inch (9.5mm) back to
allow rear air to enter the rebox. Figure 10.1.
• The rear air is used primarily during a High Burn Rate.
• In some instances rear air is desired during normal opera-
tion to help with combustion of fuel towards the back of
the rebox particularly when burning hardwoods.
• The rear air is controlled independently from the ACC
system
Figure 10.1 Start-up and Burn Rate Air Controls
Figure 10.2 Manual Timer Over-Ride
2. Manual Timer Over-Ride
If you need to shut the ACC system off before it shuts itself
off after 25 minutes (i.e. overre situation), lift up on the Start-
up Air Control and pull out from the appliance. Figure 10.2.
Manual Timer Over-Ride
G. Automatic Combustion Control (ACC)
Typically, when you build a re, you open the air controls fully
and monitor the re to prevent it from going into an overre
situation and/or burning your wood up too quickly before you
shut down the air controls to the desired burn rate.
When using the Automatic Combustion Control (ACC) system,
you do not have to continually monitor the re. Once you
set the ACC system it will control the re for you. Follow the
instructions below to learn how to operate your stove with
ease.

3. Burn Rate Air Control
• The air supply enters at the upper front of the rebox,
near the top of the glass door.
• This preheated air supplies the necessary fresh oxygen
to mix with the unburned gases, helping to create the
second, third and fourth combustion process.
• This air is regulated by the Burn Rate Air Control.
• There are four settings High, Medium-High, Medium-Low
and Low.
• When the control is raised all the way up it is on the High
setting and when pushed all the down it is on the Low
setting. Figure 11.1.
I. Burn Rates and Operating Efciency
For maximum operating efciency
1. This appliance has a timer system (ACC) that operates
the appliance at its maximum efciency removing any
guess work for the homeowner. Follow the instructions
below for each burn rate for the Start-Up Air Control and
Burn Rate Air Control. Figure 11.1.
2. Burn dry, well-seasoned wood.
Burn Rates
1. Starting a Fire and Reloading
• Open both controls fully by raising the Burn Rate Air Con-
trol all the way up until it stops and push the Start-up Air
Control back until it stops.
• The blower tends to cool the appliance. Leave the blower
off until the burn is well established, i.e., 0 minutes.
• After loading the appliance with wood and starting the
re, set both controls to the desired setting by following
the burn rate instructions below.
2. High Burn Rate - Maximum Heat*
• Raise the Burn Rate Air Control all the way up until it stops
(top marker) to a fully open position.
• Push the Start-Up Air Control all the way back until it stops
and leave it there.
• This setting over-rides the timer system (ACC) so you
must monitor the re closely while in this setting.
3. Medium-High Burn Rate - 15,000 to 30,000 BTU/hr*
• Raise the Burn Rate Air Control all the way up until it
stops (top marker) to a fully open position.
• Push the Start-Up Air Control all the way back until it
stops and then pull forward until it stops.
• This activates the timer system (ACC).
4. Medium-Low Burn Rate - 10,000 to 15,000 BTU/hr*
• Raise the Burn Rate Air Control up to the bottom of the
middle marker and stop.
Figure 11.1 Activating Timer
After activating the timer (ACC), if the control is placed
within /8 inch (9.5mm) inward from the full OUT position it
will allow rear air to enter the rebox. This will not interfere
with the timer gradually closing the front air channel in 20-24
minutes. If control is set full inward on “HI” it over-rides the
timer (ACC).
*NOTE: These are approximate settings, and will vary with
type of wood or chimney draft. Due to altitude and other
environmental circumstances, this operational information is
a guideline only.
• Push the Start-Up Air Control until it stops.
• This activates the timer system (ACC).
5. Low Burn Rate - Below 10,000 BTU/hr*
• Leave the Burn Rate Air Control at the bottom marker.
• Push the Start-Up Air Control all the way back until it
stops and then pull forward until it stops.
• This activates the timer system (ACC).
WARNING
Risk of Fire.
When set on High Burn Rate and over-riding
the Automatic Combustion Control system an
overre situation can occur and may result in a

K. Building A Fire
Before lighting your rst re in the appliance:
1. Conrm the bafe and ceramic blanket are correctly
positioned. They should be even with the front tube and
resting on all tubes. See page 12.
2. Remove all labels from glass.
There are many ways to build a re. The basic principle is
to light easily-ignitable tinder or paper, which ignites the fast
burning kindling, which in turn ignites the slow-burning re-
wood. Here is one method that works well:
1. Open the Burn Rate Air and Start-Up Air Controls fully.
2. Place several wads of crushed paper on the rebox oor.
Heating the ue with slightly crumpled newspaper before
adding kindling keeps smoke to a minimum.
. Lay small dry sticks of kindling on top of the paper.
4. Make sure that no matches or other combustibles are in
the immediate area of the appliance. Be sure the room
is ventilated and the ue unobstructed.
5. Light the paper in the appliance. NEVER light or rekindle
re with kerosene, gasoline, or charcoal lighter uid; the
results can be fatal.
6. Once the kindling is burning quickly, add several full-length
logs  to 4 inches (76 - 102mm) in diameter. Be careful
not to smother the re. Stack the pieces of wood 1/2 to
1 inch apart (1-25mm); near enough to keep each other
hot, but far enough away from each other to allow air ow
between them.
7. Set the Burn Rate Air Control and activate the timer sys-
tem (ACC).
8. When ready to reload, It is best to fully open both the Burn
Rate Air and Start-up Air Controls before reloading.
• This livens up the coalbed and reduces excessive emis-
sions (opacity/smoke).
NOTE:
• Build re on brick rebox oor.
• Do NOT use grates, andirons or other methods to support
fuel.
It will adversely affect emissions.
Odors and vapors released during initial operation.
• Curing of high temperature paint.
• Open windows for air circulation.
Odors may be irritating to sensitive individuals.
CAUTION
Fire Risk.
Keep combustible materials, gasoline
and other ammable vapors and liquids
clear of appliance.
WARNING
• Do NOT store ammable materials in the appliance’s
vicinity.
• DO NOT USE GASOLINE, LANTERN FUEL,
KEROSENE, CHARCOAL LIGHTER FLUID OR
SIMILAR LIQUIDS TO START OR “FRESHEN UP” A
FIRE IN THIS HEATER.
• Keep all such liquids well away from the heater while it
is in use.
• Combustible materials may ignite.
• Open door slowly so that ash or smoke does not exit ap-
pliance through opening.
• Large logs burn slowly, holding a re longer.
• Small logs burn fast and hot, giving quick heat.
9. As long as there are hot coals, repeating steps 6 through
8 will maintain a continuous re.

L. Wood Fuel Moisture
Seasoned Wood
• Cut logs to size
• Split to 6 inches (152 mm) or less in diameter
• Air dry to a moisture content of not more than 20%
- Soft wood - about nine months to dry
- Hard wood - about eighteen months to dry
Soft woods Hard woods
• Douglas Fir • Oak
• Pine • Maple
• Spruce • Apple
• Cedar • Birch
• Poplar
• Aspen
• Alder
The majority of the problems appliance owners experience
are caused by trying to burn wet, unseasoned wood.
• Wet, unseasoned wood requires energy to evaporate the
water instead of heating your home, and
• Causes evaporating moisture which cools your chimney,
accelerating formation of creosote.
Storing Wood
Steps to ensure properly seasoned wood:
• Stack wood to allow air to circulate freely around and
through woodpile.
• Elevate wood pile off ground to allow air circulation
underneath.
• Smaller pieces of wood dry faster. Any piece over 6 in.
(152 mm) in diameter should be split.
• Wood (whole or split) should be stacked so both ends of
each piece are exposed to air. More drying occurs through
the cut ends than the sides.
• Store wood under cover to prevent water absorption
from rain or snow. Avoid covering the sides and ends
completely.
Processed Solid Fuel Fire Logs
• NOT permitted for use in this appliance
WARNING
Fire Risk.
• DO NOT BURN GARBAGE OR FLAMMABLE
FLUIDS SUCH AS GASOLINE, NAPTHA OR
ENGINE OIL.
• DO NOT USE CHEMICALS OR FLUIDS TO START A
FIRE.
• Do NOT burn treated wood or wood with salt (driftwood).
• May generate carbon monooxide if burn material other
than wood.
May result in illness or possible death.
Hardwood vs Softwood
Your appliance performance depends on the quality of the
rewood you use.
• Seasoned wood contains about 8,000 BTUs per pound .
• Hard woods are more dense than soft woods.
• Hard woods contain 60% more BTUs than soft woods.
• Hard woods require more time to season, burn slower and
are harder to ignite.
• Soft woods require less time to dry, burn faster and are
easier to ignite.
• Start the re with softwood to bring the appliance up to
operating temperature and to establish draft.
• Add hardwood for slow, even heat and longer burn time.
• Do NOT burn wet or green wood.
• Store wood in dry location.
• Stack wood so both ends are exposed to air.
Wet, unseasoned wood can cause accumulation of
creosote.
Fire Risk.
WARNING
WARNING
Fire Risk
Do NOT store wood:
• In front of the appliance.
• In space required for loading or ash
removal.
NOTICE: Seasoning time may vary depending on drying
conditions.

Q. Opacity (Smoke)
Opacity is the measure of how cleanly your appliance is
burning.
Opacity is measured in percent:
• 100% opacity is when an object is totally obscured by
the smoke column from a chimney, and
• 0% opacity means that no smoke column can be seen.
As you become familiar with your appliance, you should
periodically check the opacity. This will allow you to know
how to burn as nearly smoke-free as possible (goal of 0%
opacity).
P. Frequently Asked Questions

Creosote - Formation and Need for Removal
• When wood is burned slowly, it produces tar and other
organic vapors, which combine with expelled moisture
to form creosote.
• The creosote vapors condense in the relatively cool
chimney ue of a slow-burning re.
• As a result, creosote residue accumulates on the ue
lining. When ignited this creosote makes an extremely
hot re.
• The chimney and chimney connector shall be inspected
every two months during the heating season to determine
when a creosote buildup has occurred.
• When creosote has accumulated it shall be removed to
reduce the risk of a chimney re.
C. Appliance Inspection - Routine
• Frequency: Every 2 months at the same time the chim-
ney and chimney connector are inspected.
• By: Homeowner
Check for:
• Cracks in glass
• Door handle - smooth cam operation
• Bafe and ceramic blanket correct placement
• Bafe for warpage
• Firebrick for cracks, broken or crumbly
• Door gasket. (Dollar bill test). Place a dollar bill between
the stove and the door and then shut the door. If you can
pull the dollar bill out, replace the door gasket.
• Glass frame for loose screws
D. Cleaning Plated Surfaces
• Frequency: As desired
• By: Homeowner
• Clean all the ngerprints and oils from plated surfaces
BEFORE ring the appliance for the rst time.
• If not cleaned properly before lighting your rst re, the
oils can cause permanent markings on the plating.
• After the plating is cured, the oils will not affect the nish
and little maintenance is required.
• Wipe clean as needed.

• Clean glass with a non-abrasive glass cleaner. Abrasive
cleaners may scratch and cause glass to crack.
• If the deposits on the glass are not very heavy, normal
glass cleaners work well. Heavier deposits may be
removed by using a damp cloth dipped in wood ashes or
by using a commercially available oven cleaner.
• After using an oven cleaner, it is advisable to remove any
residue with a glass cleaner or soap and water. Oven
cleaner left on during the next ring can permanently
stain the glass and damage the nish on plated metal
surfaces.
• A portion of the combustion air entering the rebox is de-
ected down over the inside of the door glass.
• This air ow “washes” the glass, helping to keep smoke
from adhering to its surface.
• When operated at a low burn rate, less air will be owing
over the glass and the smoky, relatively cool condition of
a low re will cause the glass to become coated.
• Operating the appliance with the Burn Rate Air Control
and Start-Up Air Control all the way open for 15-20 min-
utes should remove the built up coating.
E. Glass Cleaning
CAUTION! Handle glass assembly with care. Glass is
breakable.
• Avoid striking, scratching or slamming glass
• Avoid abrasive cleaners

Replace the rebrick if they become crumbly and/or if
there is a 1/4 inch (6.5mm) gap between the bricks.
The rebox is lined with rebrick, which has exceptional
insulating properties. Do not use a grate; simply build
a re on the rebox oor. Do not operate appliance
without rebrick.
1. After the coals have completely cooled, remove all
old brick and ash from unit and vacuum rebox.
2. Remove new brick set from box and lay out to

Bafe and blanket placement is critical to heat out-
put, efciency and overall life of the unit. Make sure
the bafe is pushed all of the way to the back of the
rebox and the blanket is laying at.
Firebrick is designed to protect your rebox. Replace
rebricks that are crumbling, cracked or broken. If
you have an optional ash door, check to make sure
the door is closing properly.
The chimney and chimney
cap must be inspected for
soot and creosote during
the burn season. This will
prevent pipe blockage, poor
draft, and chimney res.
Always burn dry wood to
help prevent cap blockage
and creosote build-up.
Keeping the door and glass
gasket in good shape will
maintain good burn times on
a low burn setting.
Check the glass frame for
loose screws to prevent air
leakage.
Check the door latch for proper adjustment. This
is very important especially after the door rope has
formed to the stove face.
Start the rst inspection of your unit af-
ter the rst 2 months of use, or if perfor-
mance changes, and adjust your sched-
ule accordingly.

4 Troubleshooting Guide
With proper installation, operation, and maintenance your woodstove will provide years of trouble-free service. If you do
experience a problem, this troubleshooting guide will assist you or a qualied service person in the diagnosis of a problem
and the corrective action to be taken.
Start Fire Problems Possible Cause Solution
Can not get re started
Excessive smoke or spillage
Burns too slowly
Not enough heat output
Not enough kindling/paper or no
kindling/paper
Use dry kindling, more paper. Arrange kindling &
wood for air movement.
Not enough air for re to ignite
Check for restricted termination cap
Check for blockage of outside air kit (if installed).
Check for ue blockage.
Pre-warm ue before starting re (refer to Building
a Fire Section).
Check for adequate vent height (refer to Chimney
Height Section).
Open window below the appliance towards the
wind.
Wood condition is too wet, too
large
Use dry, seasoned wood (refer to Seasoned Wood
Section).
Bed of coals not established
before adding wood
Start with paper & kindling to establish bed of
coals (refer to Building a Fire Section).
Flue blockage such as birds’
nests or leaves in termination
cap
Have chimney inspected for creosote and cleaned
by a certied chimney sweep.
Down draft or negative pressure
Competition with exhaust
devices
Do not use exhaust fans during start-up (refer to
Negative Pressure Section).
Open window below the appliance towards the
wind.
Fire burns too fast
Extremely dry or soft wood
Mix in hardwood.
Mix in less seasoned wood after re is established
(refer to Wood Fuel Section).
Overdrafting
Check for correct vent height; too much vertical
height creates overdrafting.
Check location of vent termination (refer to
Chimney Termination Requirement Section).
