Decorative gas appliances may be installed in  
these fireplaces. Installation must be in accor-  
dance with the National Fuel Gas Code, ANSI  
Z223.1 for compliance with the revised U.L.  
127 Standard.  
The last statement means that one big log  
weighing 10 pounds has as much heating po-  
tential as 10 pounds of twigs. However, air  
cannot get at the solid log to feed the fire so the  
solid log will burn slowly. While you would get  
the same amount of heat out of either fire, the  
smaller the pieces of wood and the more air  
spacearoundthem, thefasterthefirewillburn.  
7. Proper storage of wood, especially during  
seasoning, is essential. We recommend that  
you:  
a. Never store wood on the ground. This will  
causerottingandinsectinfiltration.Raisewood  
on flat rock or scrap wood.  
CAUTION: WHEN USING A DECORATIVE  
GAS APPLIANCE, THE FIREPLACE  
DAMPER MUST BE SET TO THE FULLY  
OPEN POSITION.  
b. Stack wood loosely to allow air circulation.  
DISPOSAL OF ASHES  
c. Store wood where it will not be excessively  
exposed to weather, such as under a tarp or  
under a roof.  
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  
or other wise locally dispersed, they should be

These fireplaces have been tested and ap-  
provedtoANSI/IAS/AGAZ21.11.2forusewith  
an unventedgas appliance having a maximum  
rating of 26,000 BTU (36 Models) and 32,000

wheninstalledwithunventedgaslogsets. The  
limit may be increased to 40,000 BTU provid-  
ingthat minimumcombustiblemantleheights  
were increased to at least 18 inches when the  
fireplace was installed.  
d. Do not stack wood directly against the walls  
of your home.  
8. Be a knowledgeable wood buyer. There is a  
difference in cord sizes. A standard cord stack  
of logs is 4 ft. high by 8 ft. long by 4 ft. deep or

Softwoods contain about 15 percent highly

shorter flames and produce steady, glowing  
coals.  
Figure 1  
A face 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  
can contain as little as 25% of the wood found  
in a standard cord.  
Wood Fuel Pointers  
2. As a general rule, denser woods contain  
morepotentialheatperpound.Mostsoftwoods  
offer moderate heat value per pound.  
Wood is a wonderful renewable fuel source.  
Normally it burns clean, leaving only a mini-  
mum of waste ash, provides comforting heat  
and can provide a variety of aromas and visual  
images.  
If you buy by the ton, remember that wood  
becomes lighter as it dries. When buying green  
or wet wood, ask for some extra poundage to  
allow for the extra water you will be getting.  
3. Differentwoodsvarywidelyinflameheights,  
flame intensities, smoke characteristics and in  
sparking. Most hardwoods do not spark.  
Youwillwanttoknowwhichwoodsarebestfor  
use. Sometimes you may want a quick, short  
fire to offset a morning chill. Soft woods are  
preferable in this case. Other times you would  
want more slow burning and a uniform heat  
output. Hardwoods are preferable for this use.  
4. Most freshly 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.  
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.  
5. Moistureandresinfoundinsideunseasoned  
wood cells will build up pressure under heat  
and explode as sparks.  
However, most wood is sold by volume, not by  
weight. To determine the best heating source,  
look at the density of various wood types.  
(Density is the weight for a given size.) The  
higher the density, the more potential heat  
output. A standard cord has a volume of 128  
cubic feet. This figure also includes the air  
space between and around the wood. The ac-  
tual volume in a standard cord is between 60  
and 100 cubic feet; depending on how tightly  
the wood is packed.  
The amount of heat available from the logs will  
be about equal on a weight basis. However,  
logsaregenerallynotweighedsotheamountof  
heat will depend on:  
6. Most wood needs to be seasoned 9 to 12  
months to reduce the moisture content and  
produce good steady fires. When moisture  
content is reduced from 60 to 20%, the gain in  
heat potential is nearly 7%.

1. The grate in the firebox should be centered  
on or over the bottom hearth so your fire can  
breath properly. Crumble and twist plenty of  
newspapers UNDER the grate and criss-cross  
some small dry kindling sticks on top of the  
paper or on the bottom of the grate.

Care and Cleaning of Your 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.  
4. Close the screens to prevent the escape of  
sparks and embers.  
STARTING A FIRE  
1. To start a fire in a the fireplace properly, first  
check the operation of the flue damper.  
5. Close the damper only when your fire is  
completelyoutandashesarecold.Keepclosed  
when fireplace is not in use to prevent unnec-  
essary loss of heated or cooled air.  
Clean the glass doors by wiping with a damp  
towel followed by a clean dry towel to remove  
streaks.  
2. To prevent smoking at start-up, close any  
window located near the fireplace when first  
lighting a fire. The closed windows may be  
reopened once a chimney draft is drawn in the  
fireplace.  
GLASS DOOR OPERATING SAFETY  
PRECAUTIONS AND INSTRUCTIONS  
Remove stubborn stains from the glass with a  
mild soap solution and a towel dampened with  
clean water. Dry with a clean dry towel.  
These fireplaces may be equipped with glass  
doors. Refer to the end of this document for a  
listingoftheglassdoorsapprovedforusewith

The fire must always be confined within the  
boundaries of the fuel grate.  
To "lock" the combustion air door closed, ensure

COMBUSTION AIR  
Aproperamountofcombustionairisimportant  
for your fireplace. Fireplaces consume large  
amounts of oxygen. It is important to allow an  
adequate supply of air.  
The fireplace screens must always be closed  
whenever the fireplace is being used.  
Combustion Air  
Actuator  
Neverslamtheglassdoorsinceitcouldcause  
the glass to break.  
If the fireplace is not equipped with an outside  
air kit, it may not obtain sufficient amounts of  
combustion air from inside the house or struc-  
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.  
Do not build excessively large or hot fires —  
scorching or discoloring of the plated brass  
trim may occur.  
Extremetemperaturechangescancauseglass

Smoke spillage often occurs when a fire is first  
started, until the fireplace and the chimney has  
had the opportunity to come up to tempera-  
ture” and to begin to function normally. If  
smoke spillage problems persist, a window  
may be opened just a crack to allow the proper  
flow of combustion air to the fireplace.  
Ifthetemperedglasspanebecomesscratched

which can cause the glass to break when  
heated. Replace the pane of glass by contact-  
ing your nearest dealer.  
CAUTION: GLASS AND METAL FRAMES  
GET HOT — ALWAYS USE HANDLES TO  
OPEN AND CLOSE THE DOORS.  
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  
REFRACTORIES  
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.  
All fireboxes contain a furnace refractory floor,  
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.  
If you have reason to believe that you do not  
have a complete outside combustion system,  
contact your 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.  
IMPORTANT: Plated polished brass glass  
doors may have a plastic covering over all  
brass pieces for protection during shipping  
and handling. The plastic covering should be  
removedbeforeinstallationoftheglassdoors.  
Under the plastic covering is a protective  
lacquercoatingwhichshouldnotberemoved.  
In some instances, if it is removed, irrevers-  
ible damage to the brass finish could occur.  
Refertothefollowingforspecificinformation  
on plated polished brass.  
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.  
WARNING: DO NOT OPERATE THE COM-  
BUSTION AIR ACTUATOR UNLESS A  
COMPLETE OUTSIDE COMBUSTION AIR  
VENT SYSTEM HAS BEEN INSTALLED  
WITH YOUR FIREPLACE.  
IMPORTANT: Thelacquer coatingonthepol-  
ished brass glass doors and trim pieces can  
be damaged or removed causing corrosion  
and/or tarnish. Do not remove the protective  
lacquer coating from plated polished doors  
and trim. To help protect the finish; use a  
non-acidic wax and avoid the over-spray of  
acidic/alkali based glass cleaners on the  
brass pieces. Please understand that the  
heat of the fire will cause the protective  
lacquer finish to slightly change to a light  
caramel color. Do not be alarmed as this is  
a normal occurrence.  
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.  
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).  
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.  
3. Anypieceofrefractorylargerthan2"(51mm)  
in radius and 3/16" deep becomes dislodged.  
If conditions 1, 2 or 3 occur, the refractory  
should be replaced.

If your do not have glass doors installed, a damp  
sheet covering the fireplace opening and sealed  
with masking tape will do. Then clean the flue  
from the top down (if an offset system, clean per  
Step 2) using a proper size chimney brush with  
flexible pole sections. Don’t open the doors or  
remove the sheet until all soot has settled.  
Vacuum, don’t sweep.  
MAINTENANCE GUIDELINES  
TROUBLESHOOTING  
No Smoking Allowed  
Your fireplace is designed to operate trouble-  
free with minimum maintenance. However, like  
any fine appliance, it deserves and requires  
some housekeeping attention.  
Your new fireplace is designed not to smoke if  
properlyinstalledandoperatedperourinstruc-  
tions. If you do experience a problem, here are  
several things to check:  
Your fireplace will perform better – and cer-  
tainly look more attractive to family and friends  
ifitiscleanedbeforeeachuse. Beforethefirst  
seasonal use in Autumn and after the last fire in  
Spring, it is important to inspect the fireplace  
system carefully. We recommend at least two  
complete fireplace inspections a year.  
1. Remember – always check to ensure your  
flue damper is in the open position before  
lighting a fire!  
4. Check the metal flashing and seals around  
your chimney. Seal any cracks or loose nail-  
head openings to prevent roof leaks.  
2. When lighting your fire, a little smoke may  
escape into the room – more likely if the chim-  
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.  
5. Clean the firebox thoroughly by using a soft  
brush or equivalent.  
Before Each Use  
WARNING: CONTINUED OVERFIRING  
CAN PERMANENTLY DAMAGE YOUR  
FIREPLACE SYSTEM. SOME EXAMPLES  
OF OVERFIRING ARE:  
1. Clean the firebox of excessive ashes. Some  
owners prefer to leave a small layer to insulate  
the cold refractory below the grate which helps  
fire starting.  
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.  
• BURNING QUANTITIES OF SCRAP  
LUMBER, PINEBRANCHES, PAPEROR  
CARDBOARD BOXES WHICH EXCEED  
THE VOLUME OF THE NORMAL LOG  
FIRE.  
This fireplace has a factory supplied grate at-  
tached, it is permissible to remove the grate for  
cleaning; however, the grate must be re-at-  
tached to the fireplace before the next burn.  
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.  
2. Keep the fireplace screens clean so combus-  
tion air flows freely.  
USE OF ARTIFICIAL WAX BASE LOGS,  
TRASH OR OTHER CHEMICALS OR  
CHEMICALLY TREATED COMBUS-  
TIBLES.  
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.  
3. Spot check the brick-like refractory for small  
cracks. Heat from the fire expands it slightly.  
When it cools, it contracts.  
CREOSOTE FORMATION AND REMOVAL  
TWICE A YEAR CHECK-UP  
Normally, twiceayear, youshouldinspectyour  
fireplace following this list:  
When wood is burned slowly, it produces tar  
and other 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.  
6. Is a vent fan, exhaust hood or central  
heating/cooling system stealing combustion  
air from your fireplace? If their volume is high  
enough, this can cause negative pressure and  
an unwanted downdraft – and smoking.  
1. Inspect the opening in your chimney top and  
remove any debris that could clog it. 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.  
7. Is your wood fuel too wet or unseasoned?  
Or does it contain some chemical substance  
that causes sputtering, smoking and toxic  
fumes?  
The chimney should be inspected at least twice  
yearly during the heating season to determine  
if a creosote build-up has occurred.  
2. Inspect the entire flue from the top down for  
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  
the firebox up to the offset/return section is the  
proper method. The beam from a powerful  
flashlight will help in this inspection.  
If creosote has accumulated, it should be re-  
moved to reduce the risk of a chimney fire.  
8. Figure 6 illustrates the correct height of  
your chimney top. It is unlikely that your instal-  
lation does not adhere to the installation  
instructions. However, ifnotcorrect, youcould  
experience an unusual downdraft. Usually, the  
best solution is to increase the chimney height.  
This may also be necessary if nearby trees,  
adjoining roof lines or a hill is causing a down-  
draft condition.  
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.  
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.  
9. Remember, your fireplace has been de-  
signed as a supplemental heating device only,  
it is not intended to heat your entire home.
