Neither the manufacturer nor the seller are re-
sponsible for any smoking or related problems
that may result from the lack of adequate com-
bustion 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 re-
sponsible for inadequate system draft caused by
mechanical systems, general construction con-
ditions, 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 refrac-
tory for the look of authenticity and to provide
safety. Do not light a fire in this fireplace without
the refractory panels in place.
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.
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 decora-
tive pillows at least 60" (1524 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 op-
tional combustion air kit may not provide all the
air required to support combustion.
GENERAL SAFETY PRECAUTIONS
IMPORTANT! READ AND
UNDERSTAND BEFORE
BUILDING 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.
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.
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
fire log warnings and cautions
marked on the packaging.
