PROCUCT FEATURES AND CONTROLS

ASH DRAWER

The large ash drawer located below the fuel door is designed to make cleaning easier by containing the ashes in a remov- able drawer.

CAUTION: Do not operate the stove with the ash dump cover off, as this will produce extreme temperatures within the stove (overfiring) and could cause damage to the appliance or other property (such damage is not covered by the manufacturers warranty). Replace the ash dump gasket if it becomes frayed or damaged.

BLOWER SYSTEM

The 250-CFM room air circulation blower system comes equipped with a variable speed control (rheostat). The blower system can be operated manually or set to operated automatically (so the blowers will turn on when the insert is hot and turn off when the insert is cool). See Care and Op- eration Section – Blower System on page 15.

PRIMARY AIR CONTROL

The primary combustion air delivery is controlled by the pri- mary air control draft module (The control handle is located above the fuel door). The heat output can be controlled by sliding the handle to a higher or lower heat output setting (see following illustrations). The fuel, the amount of heat and burn times desired, the type of installation are all variables that will affect the control setting. The same control settings in a variety of installations will produce different results. You will need to try different settings so you can learn how much heat to expect and how long the fire will burn.

CATALYTIC BYPASS DAMPER CONTROL

The bypass damper control handle is located on the front of the insert (see above illustration). By pushing in or pulling out the handle, the operator can route the exhaust either through the catalytic combustor (pushed in) or directly up the flue (pulled out). When starting a fire or refueling, the handle should be pulled out. Once the fire is established it should be pushed in.

CATALYTIC COMBUSTOR

How it works: From 5 to 30 percent of the chemical energy contained in every log escapes up the chimney when wood is burned in a conventional stove. The catalytic combustor is designed to make use of this energy, converting it into useful heat as it lessens chimney creosote build-up and air pollu- tion. The catalytic combustor consists of a durable tempera- ture resistant ceramic composition, which is extruded into a cellular, or honeycomb, configuration. After extrusion, this ceramic monolith is fired and then covered with a noble- metal catalyst. When wood smoke contacts this catalyst, chemical changes occur that causes the smoke to ignite at temperatures around 600° F. Normally, smoke will ignite and burn only at temperatures around 1000° F.
