5.0 Operation
Please read the following section before building the first
fire in your new Jøtul F
50
TL.
5.1 Use Solid Wood Fuel Only
This stove is designed to burn
natural wood only
. Wood
that has been air-dried for a period of 6 to 14 months will
provide the cleanest, most efficient heat.
Do not burn:
• Coal
• Treated or painted wood
• Garbage
• Chemical Chimney cleaners
• Cardboard • Colored paper
• Solvents
• Any synthetic fuel or logs
• Drift wood • Laminated wood
The burning of any of these materials can result in the
release of toxic fumes. Never use gasoline, gasoline-type
lantern fuel, kerosene, charcoal lighter fluid, or similar
liquids to start or “freshen-up” the fire. Always keep such
liquids away from the heater at all times.
Important: Never build or allow the fire to rest directly on
the glass panel. Try to keep the logs spaced at least one
inch from the glass to allow for proper air flow over the
glass and within the firebox.
5.2 How your Jøtul F
50
TL works
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,
WARNING
ALWAYS WEAR STOVE GLOVES WHILE TENDING THE FIRE.
NEVER ALLOW THE FIRE TO REST DIRECTLY ON THE
GLASS. KEEP THE LOGS SPACED AT LEAST ONE INCH FROM
THE GLASS TO ALLOW FOR PROPER AIR FLOW WITHIN THE
STOVE. AVOID STRIKING THE GLASS WITH LOGS.
OPERATE THIS STOVE ONLY WITH THE FRONT DOOR
AND ASH DOOR FULLY CLOSED. OPERATION WITH THE
DOOR PARTIALLY OPEN MAY RESULT IN OVER-FIRING.
IF THE DOOR IS LEFT PARTIALY OPEN, GAS AND FLAME
MAY BE DRAWN OUT OF THE STOVE CREATING SAFETY
RISKS FROM BOTH FIRE AND SMOKE.
Figure 16.
Combustion air paths
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.
5.3 Controlling the Fire
Combustion intensity is controlled by the position of an
air shutter located under the front door. You adjust its
position using the handle located under the ash lip. Slide
the handle to the left to decrease air to the fire. Sliding it
to the right increases air delivery and consequently, fire
intensity. See fig. 17. The shutter regulates and directs
primary air to the front of the burn chamber. Push it to
the right to allow maximum air to support combustion. It
should be fully open when first starting or rekindling a fire,
or when greater heat output is desired.
