When the bypass handle is open, combustion
products are directed around the catalytic
combustor. The bypass handle should be open
when first staring a fire until the catalytic combustor
heats up to activation temperature, and whenever
opening the front door to load the stove. When the
bypass handle is closed, combustion products are
directed through the catalytic combustor. The
bypass handle should be closed once the catalytic
combustor heats up to activation temperature, and
remain closed whenever the stove is burning and in
the active temperature range.

CATALYST THERMOMETER: The catalyst
thermometer monitors the downstream
temperature of the catalysts, and indicates when
the stove is in the active range for the catalysts.
When the stove is in the "active" range, the bypass
handle should be closed. When the stove is in the
"Inactive" range, the bypass handle should be

opened until the stove heats up. If the thermometer
is in the "Too Hot" range, keep the door closed, fully
close the air control, and allow the stove to cool
down until the thermometer falls into the "Active"
Range. Once the catalyst thermometer has reached
the active range, heat generated from burning
smoke keeps the catalysts warm and active as long
as fuel remains in the stove.
