BLOWER SYSTEM 
The 500-CFM room air circulation blower system comes 
equipped with a variable speed control (rheostat). The 
blower system can be operated manually or set to oper-
ate automatically (so the blowers will turn on when the 
insert is hot and turn off when the insert is cool). See 
Care and Operation Section – Blower System on page 
14. 
 

 

 
PRIMARY AIR CONTROL 
The primary combustion air delivery is controlled by the 
primary 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 instal-
lation 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 ex-
haust either through the catalytic combustor (pushed in) 
or directly up the flue (pulled out). When starting a fire or 
refueling, the handle must be pulled out. Once the fire is 
established it must be pushed in. 
 
CATALYTIC COMBUSTOR 
How it works: From 5 to 30 percent of the chemical en-
ergy contained in every log escapes up the chimney 
when wood is burned in a conventional stove. The cata-
lytic combustor is designed to make use of this energy, 
converting it into useful heat as it lessens chimney creo-
sote build-up and air pollution. The catalytic combustor 
consists of a durable temperature resistant ceramic com-
position, 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.
