c. Store wood where it will not be exces-
sively exposed to weather, such as under a
tarp or under a roof.
d. Do not stack wood directly against the
walls of your home.
Thelaststatementmeansthatonebiglogweigh-
ing 10 pounds has as much heating potential
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 space around
them, the faster the fire will burn.
8. Be a knowledgeable wood buyer.
FUELS
• 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 the equivalent of
this cubic footage. 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
littleas25%ofthewoodfoundinastandard
cord.
• 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.
Never Use Coal in Your Fireplace
DISPOSAL OF ASHES
Your fireplace system is not designed to be
used with coal derivative products. The com-
bustion process of certain types of coal can
deposit corrosive materials in the fireplace and
chimney system which can lead to premature
product failure. Never use coal as a fuel in this
fireplace system.
Ashesshouldbeplacedinametalcontainerwith
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 to be disposed of by burial in soil or other
wise locally dispersed, they should be retained
in the closed container until all cinders have
thoroughly cooled.
DECORATIVE GAS LOG SETS

SOFTWOOD VS HARDWOOD
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, 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 actual
volumeinastandardcordisbetween60and
100 cubic feet; depending on how tightly
the wood is packed. Assuming that you are
comparing two standard cords of different
species but the same volume and moisture
content,thedenserspecieswillprovidemore
BTU’s. The table of wood species/densities
reveals more helpful guidelines.
Softwoods contain about 15 percent highly
flammableresinwhichgeneratescreosotesoot
in the chimney flue. Burning softwood exclu-
sively may not be as desirable nor as safe as
burning denser hardwoods. Many experienced
fire-builders use small amounts of softwood
kindling and newspaper in conjunction with
starting a fire with split hardwood logs. Here
are some guidelines to remember:
CAUTION
When using the decorative gas
appliance, the fireplace damper
must be set in the fully open
position.
1.Softwoodsproducefastwarmingandshorter

have shorter flames and produce steady,
glowing coals.
2.Asageneralrule,denserwoodscontainmore

more slow burning and a uniform heat output.
Hardwoods are preferable for this use.
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%.

Glass Door Operating Safety
Precautions and Instructions
STARTING A FIRE
• The fire must always be confined within the
boundaries of the fuel grate.
• Thefireplacescreensmustalwaysbeclosed
whenever the fireplace is operated.
1. To start a fire in your fireplace properly, first
check the operation of the flue damper.
WARNING
To open the damper on the CST fireplaces,
push the center damper handle straight up.
To close pull handle down. See Figure 5
Thesefireplacesshouldbeoper-
atedwithbothsetsofglassdoors
fully closed. If the doors are left
openorpartiallyclosed,gasand
flame may be drawn out of the
fireplaceopening,creatingrisks
of both fire and smoke. Refer
to Figures 2 and 3 for proper
operating conditions.
•
Never slam the glass door since it could
cause the glass to break.
Do not build excessively large or hot fires.
Scorching or discoloring of the solid brass
or plated brass trim could result.
•
2. 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.
• Extreme temperature changes can cause
glass breakage — do not build a hot fire and
close the glass doors if the doors are cold.
•
If the tempered glass pane becomes
scratched or chipped, it creates a weakness
in the glass which can cause the glass to
break when heated. Replace the pane of
glass by contacting your nearest dealer or
distributor.

COMBUSTION AIR
WARNING
Aproperamountofcombustionairisimportant
for your fireplace. Fireplaces consume large
amounts of oxygen. It is important to allow an
adequate supply of air. 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 structure 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.
Thesefireplacesshouldbeoper-
ated only with the doors fully
closed (Figure 3).
CAUTION
Do not touch the doors with your
hands while the fireplace is in
use. Always use door handles.
Doorswillbecomeveryhotwhen
fireplace is in use.
Figure 4
Smoke spillage often occurs when a fire is first
started, until the fireplace and the chimney has
hadtheopportunityto“comeuptotemperature”
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.
The outside air damper should be kept closed
on all fireplaces except when the fireplace is
in operation. If there is no heat present in the
firebox,theairdampershouldbeclosedatnight
before retiring to prevent intrusion of outside
air into the home.
IMPORTANT
Plated polished brass glass
doors may have a plastic cov-
ering over all brass pieces for
protection during shipping and
handling. The plastic covering
should be removed after instal-
lation of the fireplace before its
use. Under the plastic covering
is a protective lacquer coating
whichshouldnotberemoved. In
someinstances,ifitisremoved,
irreversibledamagetothebrass
finish could occur. Refer to the
followingforspecificinformation
onplatedpolishedbrass. 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.
If your fireplace is equipped with an outside
combustion air kit, keep open at all times when
fire is burning and close when fire is out to
prevent cold air intrusion.
DAMPER OPERATION
The damper is controlled through the use of a
control lever located within the firebox opening
at the top center just behind the firebox lintel
(Figure 5). The control lever snaps into place
at the extreme range of motion, up and back in
the closed position. When pulled forward and
down, the damper is open.
Combustion Air Control
The operation and location of the outside air
control lever varies to some extent on different
fireplace models.
On the Custom Series fireplaces, the control
lever that operates the outside combustion air
valve is located on one lower side behind the
screen panel. Push the lever all the way in to
close the air valve and pull the lever all the way
out to open the air valve (Figure 4).

Proper care and “burn-in” of the firebox will
prolong the period of enjoyment without
extensive maintenance. For the first few uses,
build small fires – not roaring infernos. The
materials used in the refractories contain and
absorb moisture. It is important to “cure” the
refractories by building only modest fires.
LINTEL EXTENSION
Twice A Year Check-Up
These Custom Multi-Open Factory-Built
Fireplaces were designed, tested and listed
with an 18" (457 mm) high viewing area, floor
to lintel. However, varying conditions such as
altitude, climate, wood type, moisture content
of fuel, dwelling design peculiarities, average
ambient air pressure and humidity may effect
the performance of this fireplace. If an unac-
ceptable amount of smoking occurs while the
doors are open, the adjustable lintel can be
moved to correct the smoking condition.
Normally, twice a year, you should inspect your
fireplace following this list:
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. Removethechimneytopwhilewear-
ing gloves to guard against any sharp metal
edges.
Under normal usage, 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:
2. Inspect the entire flue from the top down for
obstructionssuchasbirdsnests,leaves,etc.
Thismaybedonebyusingaflexiblehandled
chimney cleaning brush. If the chimney
contains offset/return elbows; a soft brush
cleaningfromthetopdowntoanyelbowand
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.
3. Look up from inside the fireplace (damper
open) to see any obstructions in the lower
flue area. If present, shut the damper and
glass doors (if installed) to seal the firebox
andcontainanysootthatmightfall.Ifyourdo

brushwithflexiblepolesections.Don’topen
the doors or remove the sheet until all soot
has settled. Vacuum, don’t sweep.
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. Any piece of refractory larger than 2"
(51mm) in radius and 3/16" deep becomes
dislodged.
The lintel extension can be lowered using a
predrilled hole located at the top of the lintel
extension. See Figure 6.
TolowerthelintelextensiononModelCST38MH,
remove the screw from each end of the lintel
extension(locatedbehindthescreenassembly).
Slide the lintel extension down and align the
upperholesinthelintelextensionwiththeholes
in the lintel frame. Reattach using the screws
previously removed. Repeat this procedure for
the lintel extension on the opposite side of the
fireplace. See Figure 6.
If your refractory has a crack less than 1/4"
(19 mm) in width, a simple Refractory Patch
Kit, Model RPK, can easily be used to fill the
crack and repair the refractory.
If conditions 1, 2 or 3 occur, the refractory
should be replaced. For minor defects, repair
as noted above.

complete fireplace inspections a year.
4. Check the metal flashing and seals around
your chimney. Seal any cracks or loose
nailhead openings to prevent roof leaks.

WARNING
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.

nently damage your fireplace
system. Some examples of
overfiring are:
• Burning quantities of scrap
lumber,pinebranches,paperor
cardboard boxes which exceed
the volume of the normal log
fire.
REFRACTORIES
All fireboxes contain a furnace refractory floor.
Some models also have refractory sides and
backs. These refractories are reinforced with
steel, but can be broken by improper use.
Dropping logs on the bottom refractory and

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.
Creosote Formation and Removal
When wood is burned slowly, it produces tar
and other organic vapors, which combine with
expelledmoisturetoformcreosote.Thecreosote
vapors condense in the relatively cool chimney
flue of a slow-burning fire. As a result, creosote
residue accumulates on the flue lining. Creosote
makes an extremely hot fire when ignited.
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 7 illustrates the correct height of your chimney top. It is unlikely that your installation
does not adhere to the installation instructions. However, if not correct, you could 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 downdraft condition.
9. Remember, your fireplace has been designed as a supplemental heating device only, it is not
intended to heat your entire home.
The chimney should be inspected at least twice
yearly during the heating season to determine
if a creosote build-up has occurred.
Less Than 10'
If creosote has accumulated, it should be re-
moved to reduce the risk of a chimney fire.
2' Min.
If creosote build-up is found, do not use
chemical chimney cleaners that are poured on
a hot fire. The manufacturer considers them
dangerous and they generally only work on the
flue section nearest the fire, leaving the rest of
the flue unaffected. It is best to take the time
to clean the flue as previously described or
have the chimney professionally cleaned by a
qualified chimney sweep.
