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. This fireplace is not a heater. It is designed
to ensure homeowner comfort by providing
supplemental heat to its immediate area.

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
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 incorporat-
ing an automatic shut-off device and complying
with the Standard for Decorative Gas Appliances
for installation in vented fireplaces, ANSI Z21.60
(latest edition). 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 in the fully open
position.
attention
si vous utilisez un appareil
décoratif au gaz, le registre de
la cheminée du foyer doit être
ouvert complètement.

This fireplace has been tested and approved
to ANSI/IAS/AGA Z21.11.2 for use with an
unvented gas appliance having a maximum
rating of 26,000 BTU and complies with the
Standard for Factory-Built Fireplaces, U.L. 127,
when installed with unvented gas log sets. The
limit may be increased to 40,000 BTU provid-
ing that minimum combustible mantel heights
were increased to at least 18 inches when the
fireplace was installed.
Prior to installing any gas log set, (Vented or
Unvented) refer to the fireplace installation
instructions for verification of mantel heights
and placement of combustible materials around
the firebox opening.
NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.
important
never install an unvented gas
log set with a Btu greater than
26,000 if combustible mantel
projections are lower than
18 inches above the fireplace
opening.
attention
ne jamais installer un ensemble
de buches a gaz sans conduit
d'evacuation qui genere une
puissance superieure a 26000
si un manteau combustible est
installe plus bas que 18 po. au

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 prefer-
able 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 weigh-
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.
