Operating As A Fireplace
The 300i is tested and approved to be burned with the front
load door open and the
damper open
. In this mode of
operation you get a true fire sound as well as appearance.
Due to the crackling and popping of burning wood it is
necessary to place the optional screen (Part #
3-40-06960
)
over the door opening. This prevents sparks from entering
the room just like a screen over a fireplace. Load only small
amounts of fuel in this mode.
To operate as a fireplace, open the damper and keep it open.
Next, open the door and place the optional screen over the
door opening. Check for smoke spillage into the room. If
smoke is escaping into the room, remove the screen and
close the door. Always wear gloves when placing or removing
the screen.
blower Operation
To regulate the speed of the convection blowers, adjust from
low to high by turning the knob located on the blower cord.
The blower speed should be matched to the air control lever
setting.
When the air setting is low, the blower should always be at
the minimum setting. At higher settings, above the first air
slide indicator notch, the blower may be set to your desired
comfort level. Be sure that the blower cord does not run under,
over, above or in front of the insert.
The following guidelines for air settings can be used for wood
burning; as you become familiar with your insert, you will
know which settings best heat your home.
building and Maintaining the fire
Begin with the bypass damper open, and the air control
lever at the maximum setting, all the way to the right.
Start with a bed of crumpled paper and kindling sized
about finger width; place several 1" - 2" (25mm - 50mm)
split pieces of dry wood on top of the kindling, followed by a
few 2" - 3" (50mm - 80mm) split pieces. Lay the wood in a
crossed pattern to allow maximum air flow. Ignite the paper
and close the loading door. Allow this start-up fire to burn for
a few minutes, keeping the bypass damper open. Add about
five more pieces of wood in the 2" - 3" (50mm - 80mm) size
range, making sure that the fuel bed is all the way across
the firebox and staggered to allow airflow. Close the door
and allow this fuel to burn a few minutes.
Add increasingly larger pieces of wood to the fire until you
have a thick bed of hot embers, approximately 2" - 3" deep
at the back, and at least an inch deep at the front. You must
have this charcoal bed established before you close the
bypass damper.
Providing you have the charcoal bed described above,
close the bypass damper by pushing downward on the
handle. This will begin the highly efficient mode of operation
where the exhaust gases get re-burned in the secondary
combustion package. If you cannot achieve a charcoal bed
within the first 15 to 20 minutes, your wood is likely too wet,
and you may need to burn the fire longer and/or hotter to
compensate for the extra energy needed to drive out the
moisture.
If, after five minutes of burning with the damper closed,
smoke is visible coming from the chimney, you probably
do not have the proper coal bed. Open the bypass damper
and continue with the process until a significant coal bed is
formed.
DO NOT USE CHEMICALS OR FLUIDS TO START
THE FIRE.
never Use gasolIne, gasolIne-type lantern
fUel, Kerosene, charcoal lIghter flUId, or
SIMILAR LIQUIDS TO START OR “FRESHEN Up” A
FIRE IN THIS HEATER. kEEp ALL SUCH LIQUIDS
well away froM the heater whIle It Is In Use.
DO NOT INSTALL A gRATE TO SUppORT OR
OTHERWISE RAISE THE FIRE FROM THE FLOOR OF
THE FIREbOx.
