CARE AND OPERATION
PAGE 14
BREAK-IN PERIOD
Your fireplace insert finish is a high temperature paint that
requires time and temperature to completely cure. We rec-
ommend that you ventilate the house during the initial
burns. The paint emits non-toxic odors during this process.
KEEP YOUR HOUSE WELL VENTILATED DURING
THE CURING PROCESS TO PREVENT ACTIVATION
OF YOUR HOME SMOKE DETECTOR.
The paint manufacturer recommends three burn cycles to
cure the paint. The first two burns should be low heat, ap-
proximately 250°F., for 20 minutes each, using paper and
light kindling.
After each 20-minute burn, allow the appliance to cool
completely. The third burn should be at least medium high
or about 450°F. for 45 - 60 minutes. The paint will become
soft and emit non-toxic haze during these burns. Keep the
area well ventilated.
As the paint cures it will become slightly lighter in color.
Eventually the entire surface will become an even color.
Once the paint has been softened and cooled two or
three times, it will harden. Do not turn on a blower during
the curing process. Do not place anything on the fire-
place insert surface until the paint is completely cured.
Do not attempt to repaint the fireplace insert until the
paint is completely cured. If the surface later becomes
stained or marred, it may be lightly sanded and touched
up with spray paint from the same paint manufacturer
(See
Maintenance
– Small Area Paint Touch-up). Paint is
available at your local authorized Lennox Hearth Prod-
ucts dealer. Never attempt to paint a hot stove.
CATALYTIC COMBUSTOR
During the start-up of a cold stove, a medium to high firing
rate must be maintained for about 20 minutes. The high
firing rate will ensure that the stove, the flue, the catalyst,
and the fuel are all stabilized at proper operating tempera-
tures. Even though it's possible to have temperatures in
the stove reach 600°F. within two or three minutes after
the fire is started, do not set the primary air control lever to
the "LOW" position until approximately twenty minutes
have passed. Setting the primary air control on "LOW" too
early could result in either the fire or the catalytic combus-
tor going out.
At the end of a burn cycle, it's possible that the hot embers
remaining might not provide sufficient fuel value for the
catalyst to retain its minimum operating temperature of
600°F. During the refueling, we recommend that the stove
be refired for about 10 minutes with the bypass open to
ensure a good draw is established and that the catalyst
reaches 600° F. The refiring will ensure sufficient tempera-
tures and proper amounts of volatiles for the catalyst to
operate properly.
When refueling a hot stove with the catalyst still operating,
no refiring step is necessary. Just open the bypass, set the
primary air control to high, open the door approximately
1/2 inch, and wait for about thirty seconds. Load the fuel,
close the door, close the bypass and set the primary air
control to normal operation. Temperatures within the fire-
box should be hot enough to maintain the catalytic opera-
tion.
HOW TO START AND MAINTAIN A FIRE
1. Check to ensure the ash dump cover (in center of fire-
box floor) is in place and the ash drawer is closed.
2. Open the bypass damper control by pulling it out (to-
ward you). In the "OPEN" position the draft air will by-
pass the catalytic combustor and make starting the fire
easier.
3. Set the primary air control lever on "HIGH". The
"HIGH" setting will maximize your primary combustion
air.
4. Build a fire directly on the firebrick covering the bottom
of the stove.
a. Place five or six loosely crumpled sheets of news-
paper in the stove.
b. Add a small amount of dry kindling randomly on
the top of the newspaper.
c. Place a few more loosely crumpled newspapers
on top of the kindling and light the bottom paper
first, then light the top paper. Once the kindling is
ignited and burning on its own, close the fuel door.
The upper fire should help preheat the chimney
and create an effective draft while the lower fire
ignites the kindling.
5. When the kindling is burning well, add increasingly
larger pieces of wood until the fire is actively burning.
6. When the fire is well established, use the damper
hook and close the bypass by pushing the control rod
in (catalytic temperature probe should read 500-
600°F, takes approximately 20 - 25 minutes to reach
this temperature).
7.
When the fire is well-established slide the air control
lever for the desired heat output.
REFUELING
To refuel the stove, open the bypass and move the pri-
mary air control to "HIGH". Let the fire "LIVEN UP" for
about one minute. Open the fuel door about 1/2" and hold
in this position about 30 seconds or until the stove is draft-
ing well. Open the door and add wood. After refueling, re-
set the primary draft control to the desired position, and
close the bypass when the catalytic temperature probe
reaches operating temperatures.
