Annual Service - Jøtul GF 300 CF Installation And Operation Instructions Manual

Regulating the Pilot Flame
The pilot flame should have three flames as shown in fig.
16. The two thermo-element sticks should be surrounded
by two of the flames as shown in fig. 17.
The flames should be stable and the colour mainly blue. If
you detect a deviation from this, turn off the pilot flame
and call for service.
Adjusting the Burner
Burner adjustments must only be performed by quali-
fied personnel. To adjust the air supply, regulate the air
opening in the burner tube right above the connection of
the gas supply. See fig. 18. Loosen the wing nut under the
stove and adjust the air opening by pulling the air shutter
to the correct opening. See fig. 19.
For Natural Gas: 9.6 mm (this dimension is preset at the
factory)
For Propane: 12.6 mm (this dimension is with shutter fully
open)
Note! To avoid burns, do not adjust the air shutter
until the burner has cooled down.
Safety Switch
The TTB safety switch previously referred to in the Flue
Test section, will shut-off the gas supply to the appliance
if there is a blockage or draft reversal in the vent system.
Look for obstructions in the vent system (such as bird's
nests, or branches from bushes and trees). If the problem
persists, call for service.

Annual Service

Annual service of the appliance includes the following
check points.
Lighting the pilot flame

Cleaning the glass.

The gasket around the glass must be inspected annu-

ally for wear and replaced if necessary.
Check if the textured embers need to be replaced.

Look for soot. It could be a result of the ceramic

logs not being centered in the oven and completely
pushed onto the metal plate, or the air regulator has
been adjusted incorrectly. (see section: Adjusting the
burner)
Check the gas pressure if other gas equipment is con-

nected to the gas supply.
Look for signs of corrosion on the appliance and the

vent system.
Look for obstructions in the vent system (such as

bird's nests, or branches from bushes and trees).
