CARE AND OPERATION

BREAK-IN PERIOD

Your stove finish is a high temperature paint that re- quires 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 proc- ess.

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, approximately 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 stove surface until the paint is completely cured. Do not at- tempt to repaint the stove 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 Small Area Paint Touch-Up, page 18). Paint is available at your local au- thorized Lennox Hearth Products dealer. Never attempt to paint a hot stove.

CATALYTIC COMBUSTOR

During the start-up of a cold stove, a medium to high fir- ing 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 operat- ing temperatures. Even though it's possible to have tem- peratures 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 combustor going out.

At the end of a burn cycle, it's possible that the hot em- bers 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 temperatures and proper amounts of volatiles for the catalyst to operate properly.

When refueling a hot stove with the catalyst still operat- ing, no refiring step is necessary. Just open the bypass, set the primary air control to high, open the door ap- proximately ½” (1 cm), and wait for about thirty seconds. Load the fuel, close the door, close the bypass and set the primary air control to normal operation. Tempera- tures within the firebox should be hot enough to maintain the catalytic operation.

HOW TO START AND MAINTAIN A FIRE

1.Check to be sure the grate is in place and the ash drawer is closed.

2.Open the bypass damper control by pulling it toward you. In the "OPEN" position the draft air will bypass 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 combus- tion air.

4.Build a fire directly on the firebrick covering the bot- tom of the stove.

a.Place five or six loosely crumpled sheets of newspaper 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 burn- ing.

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 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.
