OPERATING YOUR APPLIANCE (Continued)

Maintaining Catalytic Light-Off

Your Fireplace Xtrordinair is equipped with a catalytic combustor which increases the efficiency of your appliance. It is located along the roof of the firebox and is accessed from within. Its purpose is to re-ignite the flue gases before they exit up the chimney. This process, called catalytic light-off, increases the heat output of your fireplace and reduces the amount of emissions.

While starting a fire the catalytic combustor is by-passed to allow the fire to get up to temperature. Once the fire is up to temperature the combustor by-pass control can be pushed in to allow the flue gases to be routed through the catalytic combustor. The amount of time it takes for the fire to get up to temperature varies depending upon the amount of draft and quality of wood. In most cases the appliance is up to temperature in 30 minutes or less.

When to Push in the Combustor By-Pass

The temperature in the appliance and the flue gases entering the combustor must be raised to between 500 and 700 degrees F. for the catalytic combustor to work correctly. During the start up of a cold appliance a medium to high heat range setting must be maintained for a minimum of 20 minutes. This insures that the appliance, catalyst and fuel are all stabilized at their proper operating temperature. Even though it is possible to have gas temperatures reach 600 degrees F. within 2 to 3 minutes after a fire is started, if the fire is allowed to die down immediately it may go out and the combustor may stop working. Once the combustor starts working, the heat generated in it by burning the smoke will keep it working.

What to do After Refueling Your Fireplace

During the refueling and rekindling of a cool fire or a fire that is in the charcoal phase, operate the appliance at a medium to high firing rate for about 10 minutes to insure that the catalyst reaches approximately 600 degrees F. This will insure catalytic light-off.
