GENERAL SAFETY PRECAUTIONS
IMPORTANT! READ AND UNDERSTAND BEFORE YOUR FIRST FIRE.
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, produce abnormally high temperatures and
sputtering, smoking fires.
WARNING: DO NOT POKE OR STIR PROCESSED SOLID FUEL LOGS WHILE THEY
ARE BURNING. ONLY USE LOGS THAT
HAVE BEEN EVALUATED FOR APPLICATION IN THE FIREPLACE AND REFER TO
ALL FIRELOG WARNINGS AND CAUTIONS
MARKED ON THE PACKAGING.
Never burn treated construction lumber or
scraps. These woods burn excessively hot and
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, or similar
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 .
4. Never block or restrict the room air intake
grille across the bottom front or the warm air
outlet grille across the top front of the fireplace.
5. Use care when selecting window treatments
for windows located near the fireplace. Avoid
using combustible flowing window treatments
such as curtains on nearby windows that are of
sufficient length to be blown in front of an open
flame when the window is opened.
6. With the fire burning, close the protective
mesh screens to keep sparks and embers
INSIDE the firebox.
7. Keep any combustible furniture or decorative 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
handling fireplace tools such as shovels, tongs
or pokers.
10. Never modify or alter your fireplace system in any way. To do so may create a potential
fire 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 the manufacturer for
use with this fireplace.
13. If you are using your fireplace as a “decorative
appliance,” such as with a permanently installed
gas log set, the fireplace damper must 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
with modern energy efficient features, the optional combustion air kit may not provide all the
air required to support combustion. Neither the
manufacturer nor the seller are responsible for
any smoking or related problems that may
result from the lack of adequate combustion
air. It is the responsibility of the builder/contractor to ensure that adequate combustion air
has been provided for the fireplace.
15. Neither the manufacturer nor the seller
warrants "smoke free" operation nor are they
responsible for inadequate system draft caused
by mechanical systems, general construction
conditions, inadequate chimney heights, adverse wind conditions and/or unusual
environmental factors or conditions beyond
our control.
GENERAL INFORMATION
1. The all-steel, multi-wall firebox is the heat
center of the system. It is well insulated for
safe clearance to combustibles.
2. The hearth floor and sidewalls of the firebox
are lined with a brick pattern reinforced refractory for the look of authenticity and to provide
safety.
3. The metal chimney sections extending from
the firebox top to beyond your roof are two
walled and air-cooled. The inner passage, or
flue, provides the exit for smoke and gases.
4. The flue damper is a two position (fully open
or fully closed) mechanism operated by a
handle found at the center top of the fireplace
opening. It must be open when fire is present
so smoke and gases can escape. It should be
closed ONLY when the fire is completely out –
keeping room air from being lost up the flue.
5. Closed screens prevent fire, sparks and
embers from popping out of the firebox while
a fire is burning. Pull screens back when
adding wood to the firebox.
6. Why use a fuel grate? Besides positioning
the firebed properly, it protects the refractory
floor, back and sides of the fireplace. Further,
it ensures a proper flow of combustion air into
and around the firebed. The grate must be
used at all times when burning. Your warranty
may be voided without the use of this grate.
7. Remember, your fireplace is not intended to
heat your entire home.
FUELS
Never Use Coal in Your Fireplace
Your fireplace system is not designed to be
used with coal derivative products. The combustion 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.

Gas Logs
If your fireplace system was installed with a gas
line, you may wish to install one of two types of
gas log sets.
This fireplace has been tested and approved for
use with a decorative gas appliance incorporating an automatic shut-off device and complying
with the Standard for Decorative Gas Appliances for installation in vented fireplaces, ANSI
Z21.60 (1991). Decorative gas appliances may
be installed in these fireplaces. Installation
must be in accordance with the national Fuel
Gas Code, ANSI Z223.1 for compliance with the
revised U.L. 127 Standard.
CAUTION: WHEN USING A DECORATIVE
GAS APPLIANCE, THE FIREPLACE
DAMPER MUST BE SET TO THE FULLY
OPEN POSITION.
These fireplaces have been tested and approved to ANSI/IAS/AGA Z21.11.2 for use with
an unvented gas appliance having a maximum
rating of 40,000 BTU and complies with the
Standard for Factory-Built Fireplaces, U.L. 127,
when installed with unvented gas log sets.
Prior to installing any gas log set, (Vented or
Unvented) refer to the fireplace installation
instructions for verification of mantle heights
and placement of combustible materials around
the firebox opening. NEVER INSTALL AN
UNVENTED GAS LOG SET WITH A BTU RATING GREATER THAN 40,000 BTU. Vented gas
log sets do not have restrictions placed upon
their BTU rating.
Wood Fuel Pointers
Wood is a wonderful renewable fuel source.
Normally it burns clean, leaving only a minimum of waste ash, provides comforting heat
and can provide a variety of aromas and visual
images.
You will want to know which woods are best for
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.
The amount of heat available from the logs will
be about equal on a weight basis. However,
logs are generally not weighed so the amount
of heat will depend on:
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 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.
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.
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.
SOFTWOOD VS HARDWOOD
Softwoods contain about 15 percent highly
flammable resin which generates creosote soot
in the chimney flue. Burning softwood exclusively 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:
1. Softwoods produce fast warming and shorter
fires. Hardwoods burn less vigorously, have
shorter flames and produce steady, glowing
coals.
2. As a general rule, denser woods contain
more potential heat per pound. Most softwoods
offer moderate heat value per pound.
3. Different woods vary widely in flame heights,
flame intensities, smoke characteristics and in
sparking. Most hardwoods do not spark.
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.
5. Moisture and resin found inside unseasoned
wood cells will build up pressure under heat
and explode as sparks.
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%.
7. Proper storage of wood, especially during
seasoning, is essential. We recommend that
you:
a. Never store wood on the ground. This will
cause rotting and insect infiltration. Raise wood
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. 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
the equivalent of this cubic footage, (
Figure 1

Cord of
8'
Wood

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.
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.
9. When comparing woods of the same moisture content and same species, we find most
woods have approximately the same heating
potential per pound.
