F 50 Tl Rangeley Functionality; Air Control; Top Loading - Jøtul F 50 TL Rangeley Installation And Operating Instructions Manual

NOTE: Avoid letting logs rest directly on the glass panel. The
logs should be spaced off of the glass enough to allow for
proper air flow within the firebox.

5.4 F 50 TL Rangeley Functionality

When used with dry wood and a well-drafting chimney
system, modern non-catalytic wood stoves burn fuel
efficiently by the precise control and delivery of primary and
secondary air to the fire.
Primary Air is drawn into a front inlet in the stove bottom
and directed through a regulator shutter under the front
door before entering the lower fire chamber. Additional
primary air is directed to the top of the front door to act as
an air wash which may prevent extreme soot build-up on
the glass panel. The amount of primary air available to the
fire determines the intensity of heat output and rate of fuel
combustion; the greater the amount of air, the greater the
heat output, the faster the wood burns. The primary air
setting also determines the effectiveness of the air wash over
the glass; the higher the setting, the cleaner the glass.
Additional air is separately directed into the top of the fire
chamber to support combustion of exhaust gasses before
passing out of the stove. This unregulated Secondary Air
enters through an inlet in the rear of the stove bottom
and is heated as it passes through the rear of the stove
into a two-tiered manifold at the top of the firechamber.
Additional secondary air is directed through a stainless steel
tube built into the baffle plate hinge.
Volatile gases, released unburned from the fuel bed, rise to
the baffle where they are turbulently mixed with the hot,
fresh oxygen. Secondary combustion then occurs before the
gases pass into the heat exchange chamber. See fig. 16.

5.6 Top Loading

You will want to take advantage of the convenience of
adding logs to a burning fire through the top of your stove.
The hinged heat exchanger baffle must be in the open
position in order to add wood to the fire through the top
of the stove. The baffle handle can be set in any of four
positions, however, we recommend that you orient it to
mimic the orientation of the baffle itself.; i.e. when the
side handle is in a horizontal position, the baffle is also in a
horizontal position - Closed. Swing the handle down into a
vertical position to open the baffle. See fig. 18 and section
5.7 for more details.
