Adjusting The Temperature; Turning Off The Fireplace; The Combustion Principle For Gas; Required Heat During Combustion - Jøtul GF 3 CF Instrucciones Para Instalación

ENGLISH
If the pilot does not stay lit, turn knob (1) to the right until it
stops. Continue to press the knob down while turning to the
right to the "OFF" position. Call your service technician or gas
supplier.
Note! When the appliance is used for the first time,
condensation may form in the fire box. Some smoke may
also appear from the appliance during the initial hours,
due to the burning off of paint and lubrication used in the
production process. See Lighting section Odours when using
the stove for the first time.
If the appliance shuts off in operation for no apparent reason
(especially during windy or stormy conditions) and will not
relight, it is possible that the flue system safety switch has
operated. Allow the appliance to cool down and relight. Any
obstruction to the flow of exhaust gases up the flue can
cause this switch to operate thereby making the situation
safe. If the appliance cuts out repeatedly, do not continue to
use the appliance and seek flue checking and service from
qualified personnel before re-using the appliance.

Adjusting the temperature

Make sure the appliance has been operating for at least
45 minutes before adjusting the flame.
To adjust the temperature, use the knob 2 on the left (fig. 2)
The knob has a scale from min. to max. This will correspond
to a scale from 15 to 45 degrees. Turn the knob to desired
temperature.

Turning off the fireplace

In order to fully extinguish the fireplace, push in the gas
control knob 1 (fig. 2) and turn clockwise to "OFF". Do not
use force.

The combustion principle for gas

Combustion requires 3 main ingredients: Heat, fuel and
oxygen. If one of the main ingredients is altered, it may
result in incomplete combustion. This basic principle is
important to remember in the trouble-shooting process.
Combustion is not possible if one of the 3 ingredients is
missing.
Oxygen blend:
Natural Gas: 10 m oxygen to 1 m
3
LPG: 24 m 3 oxygen to 1 m 3 LPG

Required heat during combustion

Constant flame heat during use of the fireplace is crucial
for complete combustion. The personnel installing and
servicing the fireplace must be certain about placing the
ceramic logs/coal set in its correct place. The customer
must also be made aware of this, if the customer personally
is going to remove and replace the logs or coals.

If the ceramic logs or coals are obstructing the flame in an
incorrect way, they may attract heat from the flame and
consequently lower the temperature of the flame. This
would result in incomplete combustion, poor flame pattern
and increasing values of carbon monoxide (CO). A high
production of CO could lead to accumulation of soot on the
ceramic logs or coals, the glass and on the exterior of the
building.
Generation of sparks at the pilot
head
Jøtul GF 3 CF is equipped with a valve with a built in spark
ignitor. When the control knob on the spark ignitor is
pushed to the bottom and turned, it generates a spark of
920°C. The spark is conducted via an insulated wire to the
pilot burner, where it is conducted into an electrode
fastened with ceramic insulation . The hot spark jumps from
the tip of the electrode, to the pilot head and returns to
the ground connection. The hot spark is sufficient to light
natural gas and LPG.
The spark ignitor in a gas stove generates: 920°C
Natural gas requires: 620 °C
LPG require: 500-600°C

Trouble-shooting

When no spark is generated at the
pilot head (fig. 6)
It is uncommon for the spark ignitor to fail, unless it has
mechanical damage. If the spark is seen at the pilot, it could
be the result of a break in the electrical circuit leading up
to the pilot head. The spark is "small" or weak if there is too
much resistance from a bent wire, or if corrosion appears
at the electrode (A) or the pilot head (B). This could result in
insufficient heat to light the gas.Inspect the pilot burner
by looking for damage to the individual parts. Check for
damaged wires or wires crushed between plate sections
of the appliance and check for loose connections.
Follow the trouble-shooting procedure below
when no sparks are generated at the pilot
head (fig. 6):
• Make sure the spark gap between electrode (A) and
pilot head (B) is smaller than or equal to 3.2 mm.
• If not: check if the electrode is loose or damaged.
• Make sure the insulated wire is intact and without
cracks and properly connected between the valve and
electrode (A).
• If not: properly fasten the insulated wire to establish a
connection between the spark ignitor and the electrode.
Replace the electrode if the wire is damaged or cracked.
• Make sure the ceramic insulation (C) is intact and
without cracks.
• If not: Replace the electrode.
