FUELS
Never Use Coal in Your Fireplace
Your fireplace system is not designed to be
used with coal derivative products. The com-
bustion process of certain types of coal can
depositcorrosivematerialsinthefireplaceand
chimney system which can lead to premature
productfailure. Neverusecoal as a fuel inthis
fireplace system.
Gas Logs

6. With the fire burning, close the protective
mesh screens to keep sparks and embers IN-
SIDE the firebox.
7. Keep any combustible furniture or decora-
tive pillows at least 36" (914 mm) from the
fireplace opening.
8. Never leave your fireplace unattended while
it is burning.
9. Be careful adding wood fuel to the fire or

hazard and void the Limited Warranty.
11. The bottom refractory can be cracked by
excessive abuse such as tossing heavy logs
onto the grate or gouging with fireplace tools.
Exercise caution when adding wood to your
fireplace.
12. DO NOT use a fireplace insert or any other
product not specified by Superior for use with
this fireplace.
13. If you are using your fireplace as a “deco-
rative appliance,” such as with a permanently
installedgaslogset,thefireplacedampermust
be permanently fixed in the open position.
Listed “vent-free” gas log sets may be used
with the damper closed.
14. Always ensure that an adequate supply of
replacement combustion air from the outside of
the house is accessible to the fire to support
normal combustion. Fireplaces consume large
volumes of air during the normal combustion
process. In the event the home is tightly sealed
withmodernenergyefficientfeatures,theoptional
combustion air kit may not provide all the air
required to support combustion. The manufac-
turerisnotresponsibleforanysmokingorrelated
problemsthatmayresultfromthelackofadequate
combustion air. It is the responsibility of the
builder/contractor to ensure that adequate com-
bustion air has been provided for the fireplace.
GENERAL SAFETY PRECAUTIONS
IMPORTANT! READ AND UNDER-
STANDBEFOREYOURFIRSTFIRE.
1. Use SOLID WOOD only for fuel. It is best to
use dry and well seasoned hardwood. Soft
woods tend to burn very quickly. DO NOT use
treated wood, charcoal, coal, trash, driftwood
or woods that have been dipped in tar, pitch,
pine tar, creosote, etc. Wood products made
with synthetic binders, such as plywood, pro-
duce abnormally high temperatures and
sputtering, smoking fires. When burning arti-
ficial logs, please read and follow the
instructions provided by the manufacturer.
Never burn treated construction lumber or
scraps. Thesewoodsburnexcessivelyhotand
may contain chemicals used to treat insects
and fungus. When burned, these chemicals
can pose a significant hazard.
2. NEVER use gasoline, gasoline-type lantern
fuel,kerosene, charcoal lighter fluid,orsimilar
liquids to start or “freshen up” a fire in this
fireplace. Keep any flammable liquids a safe
distance from the fireplace.
3. Keep the chimney damper open while any
fire or smoldering embers are present .

1. The type of wood used.
2. How dry it is.
3. How many logs you put in.
4. The size of the logs.
The last statement means that one big log
weighing 10 pounds has as much heating po-
tential as 10 pounds of twigs. However, air

the same amount of heat out of either fire, the
smaller the pieces of wood and the more air

DISPOSAL OF ASHES
Ashes should be placed in a metal container
with a tight fitting lid. The closed container of
ashes should be placed on a noncombustible
floor or on the ground, well away from all
combustible materials, pending final disposal.
Iftheashesaretobedisposedofbyburialinsoil
orother wise locally dispersed, theyshould be
retainedintheclosedcontaineruntilallcinders
have thoroughly cooled.
SOFTWOOD VS HARDWOOD
Softwoods contain about 15 percent highly
flammableresinwhichgeneratescreosotesoot
in the chimney flue. Burning softwood exclu-
sively may not be as desirable nor as safe as
burningdenserhardwoods.Manyexperienced
fire-builders use small amounts of softwood
kindling and newspaper in conjunction with
startingafirewithsplithardwoodlogs.Hereare
some guidelines to remember:
1. Softwoods produce fast warming and shorter
fires. Hardwoods burn less vigorously, have
shorterflamesandproducesteady,glowingcoals.
2. As a general rule, denser woods contain
morepotentialheatperpound.Mostsoftwoods
offer moderate heat value per pound.
3.Differentwoodsvarywidelyinflameheights,
flame intensities, smoke characteristics and in
sparking. Most hardwoods do not spark.
4. Mostfreshly cut “green” wood will not burn
well and will smoke. Green wood can be from
10 to 40 percent less efficient than air-dried
seasoned wood.
5.Moistureandresinfoundinsideunseasoned
wood cells will build up pressure under heat
and explode as sparks.
Aface cord is the same height and length as a
standard cord but the depth is only the length
of the logs (12, 18 or 24 inches). A face cord
cancontainaslittleas25%ofthewoodfound
in a standard cord.
If you buy by the ton, remember that wood
becomeslighterasitdries.Whenbuyinggreen
or wet wood, ask for some extra poundage to
allow for the extra water you will be getting.
9. When comparing woods of the same mois-
ture content and same species, we find most
woods have approximately the same heating
potential per pound.
However, most wood is sold by volume, not by
weight. To determine the best heating source,
lookatthe density of variouswood types. (Den-
sityistheweightforagivensize).Thehigherthe
density, the more potential heat output.

6. Most wood needs to be seasoned 9 to 12
months to reduce the moisture content and
produce good steady fires. When moisture
contentisreduced from 60to 20%, the gainin
heat potential is nearly 7%.
7. Proper storage of wood, especially during
seasoning,isessential.Werecommendthatyou:
a. Never store wood on the ground. This will

on flat rock or scrap wood.
b. Stack wood loosely to allow air circulation.
c. Store wood where it will not be excessively
exposed to weather, such as under a tarp or
under a roof.
d. Donotstackwooddirectlyagainstthewalls

8. Be a knowledgeable wood buyer. There is a
difference in cord sizes. A standard cord stack

FIREPLACE OPERATION.
Care and Cleaning of Glass Doors
Never clean the glass when the doors are hot.
Do not use ammonia or ammonia based glass
or household cleaner to clean the glass or the
door frame. An ammonia based cleaner will
damage the finish of the glass door.
Clean the glass doors by wiping with a damp
towel followed by a clean dry towel to remove
streaks.
Remove stubborn stains from the glass with a
mild soap solution and a towel dampened with
clean water. Dry with a clean dry towel.
WARNING: IF YOUR FIREPLACE IS EQUIPPED
WITH GLASS DOORS, IT SHOULD BE OPER-
ATED WITH THE DOORS FULLY OPEN OR
FULLY CLOSED. IF THE DOORS ARE LEFT
PARTIALLY OPEN, GAS AND FLAMES MAY BE
DRAWN OUT OF THE OPENING, CREATING
RISKS OF BOTH FIRE AND SMOKE. REFER TO
FIGURES 3 AND 4 FOR PROPER OPERATING
CONDITIONS.
Assuming that you are comparing two standard
cords of different species but the same volume
and moisture content, the denser species will
provide more BTU’s. The table of wood species/
densities reveals more helpful guidelines.

STARTING A FIRE
1. To properly start a fire in a the fireplace, first
check the operation of the flue damper (see
“DAMPER CONTROL” and Figure 2, below).
2. To prevent smoke at startup, close all
windows near the fireplace when first lighting
a fire. The closed windows may be reopened
once a chimney draft is drawn in the fireplace.
3. Center the grate in the firebox on or over the
bottom hearth so the fire can breathe properly.
Crumbleand twist plenty of newspapersUNDER
the grate, and criss-cross some small, dry
kindling sticks on top of the paper or on the
bottom of the grate.
4. Build a pyramid of three split logs (split
wood will light more quickly). Arrange the logs
to provide plenty of air space between them.
5. Light the paper at both sides of the firebox.
6. Close the screens to prevent the escape of
sparks and embers.
7. Close the damper only when the fire is
completely OUT and ashes are COLD. Keep
the damper closed when the fireplace is not in
use, to prevent unnecessary loss of conditioned
room air.
DAMPER CONTROL
This fireplace is fitted with a manually con-
trolled chimney damper.
The damper is controlled through the use of a
damper rod inside the top center of the firebox
opening, behind the lintel (Figure 2).
•To CLOSE the damper, pull the damper rod
FORWARD (toward the front of the fireplace),
then slide all the way LEFT until locked in
position.
•To OPEN the damper, pull the damper rod
FORWARD (toward the front of the fireplace),
then slide all the way RIGHT until locked in
position.
When the fireplace is NOT in use, the damper
should remain CLOSED to prevent cold air
from entering the home through the chimney
system.
When the fireplace is in use, the damper
MUST remain OPEN.

REFRACTORIES
Allfireboxes contain afurnacerefractoryfloor,
sides and back. These refractories are rein-
forcedwithsteel,butcanbebrokenbyimproper
use. Dropping logs on the bottom refractory
and building fires directly against the refracto-
ries can cause premature burnout of these
components. It may easily be repaired or re-
placedatcostsfarbelowrepairandmaintenance
for masonry fireplaces.
Proper care and “burn-in” of the firebox will
prolong the period of enjoyment without exten-
sive maintenance. For the first few uses, build
small fires – not roaring infernos. The materials
usedintherefractoriescontainandabsorbmois-
ture. It is important to “cure” the refractories by
buildingonlymodestfires.Undernormalusage,
it is expected that hairline cracks will appear in
the refractory surface. These hairline cracks do
not affect the safe operation of the fireplace.
Refractories should be replaced when:
1. The crack opens more than 1/4" (19 mm).
2. Pitting in the surface is extensive and pits
become deeper than 3/16" (4.76 mm).
3.Anypieceofrefractorylargerthan2"(51mm)
in radius and 3/16" deep becomes dislodged.
If conditions 1, 2 or 3 occur, the refractory
should be replaced.
Figure 5
To provide outside combustion air to your
fireplace while it is in operation, locate the
combustion air actuator along the right side of
the fireplace opening behind the screen.
To operate, push the end of the actuator to the
left as shown in
Figure 5 , until it "pops" free of
its "locked" position. Pull the actuator forward
to open the combustion air door, and push it
back to close.
COMBUSTION AIR
Aproperamountofcombustionairisimportant
for your fireplace. Fireplaces consume large
amountsof oxygen. It is importantto allow an
adequate supply of air.
If the fireplace is not equipped with an outside
air kit, it may not obtain sufficient amounts of
combustionairfrominsidethehouseorstruc-
ture in which it is installed. Therefore, the fire
may draw from an outside air source and pull
air in through the chimney. This may cause
smoke spillage into the room.
Smokespillage often occurswhenafireisfirst
started,until the fireplaceandthechimneyhas
had the opportunity to “come up to tempera-
ture” and to begin to function normally. If
smoke spillage problems persist, a window
maybeopened just a crack toallowthe proper
flow of combustion air to the fireplace.
If your fireplace is equipped with an outside
combustion air kit, keep it open at all times
when fire is burning and close when fire is out
to prevent cold air intrusion.
Combustion Air Control
The actuator for combustion air system is
standard on all fireplaces but must not be
operated if the complete system is not in-
stalled. See
Figure 5 and refer to Figure 2 .
If you have reason to believe that you do not
have a complete outside combustion system,
contactyour distributor to have your fireplace
inspected for the presence of the complete
system before you use the combustion air
actuator. DO NOT assume that you have this
systeminplacebecauseyouhaveanactuating
lever present on your fireplace front face.

MAINTENANCE GUIDELINES
Your fireplace is designed to operate trouble-
freewithminimummaintenance.However,like
any fine appliance, it deserves and requires
some housekeeping attention.
Your fireplace will perform better – and cer-
tainlylookmoreattractivetofamilyandfriends
–ifitiscleanedbeforeeachuse.Beforethefirst
seasonaluseinAutumnandafterthelastfirein
Spring, it is important to inspect the fireplace
system carefully. We recommend at least two
complete fireplace inspections a year.
Before Each Use
1. Clean the firebox of excessive ashes. Some
owners prefer to leave a small layer to insulate
thecold refractory below the grate which helps
fire starting.
This fireplace has a factory supplied grate at-
tached,itispermissibletoremovethegratefor
cleaning; however, the grate must be re-at-
tached to the fireplace before the next burn.
2.Keepthefireplacescreenscleansocombus-
tion air flows freely.
3.Spotcheckthebrick-likerefractoryforsmall
cracks. Heat from the fire expands it slightly.
When it cools, it contracts.
TWICE A YEAR CHECK-UP
Normally,twiceayear,youshouldinspectyour
fireplace following this list:
1.Inspecttheopeninginyourchimneytopand
removeany debristhatcouldclogit.The cap is
usually held in place by four (4) screws, which
remove easily for checking or cleaning the full
length of the flue from above. Remove the
chimney top while wearing gloves to guard
against any sharp metal edges.
2. Inspecttheentireflue from the top downfor
obstructions such as birds nests, leaves, etc.
This may be done by using a flexible handled
chimney cleaning brush. If the chimney con-
tainsoffset/returnelbows;asoftbrushcleaning
from the top down to any elbow and then from
thefirebox uptotheoffset/returnsection is the
proper method. The beam from a powerful
flashlight will help in this inspection.
3. Look up from inside the fireplace (damper
open) to see any obstructions in the lower flue
area.Ifpresent,shutthedamperandglassdoors
(if installed) to seal the firebox and contain any
soot that might fall.
TROUBLESHOOTING
No Smoking Allowed
Your new fireplace is designed not to smoke if
properlyinstalledandoperatedperourinstruc-
tions.If you do experience a problem, here are
several things to check:
1. Remember – always check to ensure your
flue damper is in the open position before
lighting a fire!
2. When lighting your fire, a little smoke may
escapeinto the room – more likely if thechim-
ney is cold. To correct this, hold a lighted
newspaper up inside the firebox near the open
flue damper. This will turn around any down-
draft and clear the flue of cold air. As your log
fireburnsbelow,theupdraftwillimproveasthe
chimney heats up.
3. Is your fire too far forward? Move it toward
the back with your poker. Keep the fire well
within the confines of your fuel grate.
4. Keep your fire up on the grate and the
refractory below free of excessive ashes. The
fire needs plenty of air movement around the
logs.
5. If smoking occurs an hour or two after
lighting the fire, perhaps your well-insulated
house is too airtight and there is scarcely any
way for replacement air to enter and feed the
fire.Checktoseeifyouroutsidecombustionair
kit(ifinstalled)isopen.Checkoutsidetoensure
noobstructionsareinfrontofexteriorairentry.
Open a window slightly, open doors to one or
two rooms and see if this stops the smoking.
6. Is a vent fan, exhaust hood or central
heating/cooling system stealing combustion
airfrom your fireplace? If their volumeishigh
enough,thiscan cause negative pressure and
an unwanted downdraft – and smoking.
7. Is your wood fuel too wet or unseasoned?
Or does it contain some chemical substance
that causes sputtering, smoking and toxic
fumes?
8.
Figure 6 illustrates the correct height of
yourchimneytop.Itisunlikelythatyourinstal-
lation does not adhere to the installation
instructions.However,ifnotcorrect,youcould
experienceanunusualdowndraft. Usually,the
bestsolutionistoincreasethechimneyheight.
This may also be necessary if nearby trees,
adjoiningrooflinesor a hill is causingadown-
draft condition.
9. Remember, your fireplace has been de-
signed as a supplemental heating device only,
it is not intended to heat your entire home.
CREOSOTE FORMATION AND REMOVAL
When wood is burned slowly, it produces tar
andother organic vapors, which combine with
expelled moisture to form creosote. The creo-
sote vapors condense in the relatively cool
chimneyflueofaslow-burningfire.Asaresult,
creosote residue accumulates on the flue lin-
ing. When ignited, this creosote makes an
extremely hot fire.
Thechimneyshouldbeinspectedatleasttwice
yearly during the heating season to determine
if a creosote build-up has occurred.
If creosote has accumulated, it should be re-
moved to reduce the risk of a chimney fire.
Ifcreosotebuild-upisfound,donotusechemi-
cal chimney cleaners that are poured on a hot
fire. The chemical cleaners can be dangerous
and generally only work on the flue section
nearest the fire, leaving the rest of the flue
unaffected.Itisbesttotakethetimetocleanthe
flue as previously described or have the chim-
ney professionally cleaned by a qualified
chimney sweep.
If your do not have glass doors installed, a
dampsheetcoveringthefireplaceopeningand
sealed with masking tape will do. Then clean
thefluefromthetopdown(ifanoffsetsystem,
clean per Step 2) using a proper size chimney
brush with flexible pole sections. Don’t open
thedoorsorremovethesheetuntilallsoothas
settled. Vacuum, don’t sweep.
4. Check the metal flashing and seals around
your chimney. Seal any cracks or loose nail-
head openings to prevent roof leaks.
5.Cleanthefireboxthoroughlybyusingasoft
