Engaging the Catalytic Combustor
Prior to opening the front door, the catalytic combustor bypass should
be opened (swing upwards). Engage the combustor by swinging the
bypass handle on the right-hand side of the stove until it closes
completely. This applies when first starting a fire, or when reloading
wood onto hot coals. Opening the catalytic combustor bypass prior to
opening the front door when hot coals remain may also help to reduce
some smoke out into the room. It is recommended to slightly crack the
front door for up to 15 seconds to let airflow normalize before slowly
opening the front door just wide enough to reload wood. The front door
should be left open for as little time as possible.
The catalytic combustor burns the gases and particles in the exhaust
when the temperature of the smoke reaches approximately 500ºF
going through the catalytic combustor, or typically after about 5-15
minutes of establishing a strong fire. After this time, the catalytic
combustor should be closed.
