14. RECTIFYING PROBLEMS
Problem Potential causes Solutions
Insufcient heat • Gas supply not open
• Venturi tubes not situated above the
openings of the gas valves
• Burner openings blocked
• Gas bottle (almost) empty
• Pressure regulator not correctly connected
to bottle and/or hose
• Open gas supply
• Place venturi tubes above the openings of
the gas valves
• Clean burner openings or replace burners
• Replace gas bottle
• Reconnect pressure regulator to bottle and/
or hose
Too hot and/or are-ups • Food too fatty
• Fat drain openings blocked,
fat in bowl, and/or on burners
• Temperature too high
• Cut off excess fat or select a lower heat for
the burners
• Clean fat drain opening, bowl, and burners
• Select a lower heat for the burners and/or
grill food indirectly
Heat not evenly distributed
over grill surface
• Some difference in heat is normal, see
"1.7 Using the heat efciently" and "10.6
Using the heat zones". Potential causes of
considerable differences in heat:
• Appliance not pre-heated
• Pre-heat appliance
Yellow ames • Burners or venturi tubes blocked
• Salt on burners
• Appliance connected to butane
• Clean burners and venturi tubes
• Clean burners
• Connect appliance to propane and use a
suitable pressure regulator
Incomplete ame • Burner blocked, pierced, or corroded • Clean or replace burner
Flashbacks (ames outside
of venturi tubes/at control
knobs)
• Burners or venturi tubes blocked • Close the gas supply and set the burners to
OFF.
• Allow the appliance to cool.
• Clean burners and venturi tubes.
Flames higher than edge of
bowl
• Wind
• Gas bottle (almost) empty
• Fat in bowl and/or on burners
• Turn rear of appliance to wind
• Replace gas bottle
• Clean bowl and burners
Pressure regulator buzzing • Warm weather
• New (full) gas bottle
• No hazard or fault; stops automatically
after a short period of time.
Burner whistles when set to
LOW
• Gas injector, venturi tube, and/or burner
soiled
• Clean gas injector, venturi tube, and burner
Igniting burner fails
(both with igniter and
match)
• Burner or venturi tube blocked
• No gas supply
• Clean burner and venturi tube
• Open gas supply and press safety button
on pressure regulator (not present on all
regulators)
Igniting burners fails
with igniter
• No battery inserted or battery inserted
incorrectly
• Middle burner not ignited rst
• Igniter wiring not correctly connected
• Electrode damaged
• Incorrect grounding
• Defective igniter
• Re-insert/insert battery with correct polarity
• Ignite middle burner rst
• Check all igniter connections and
re-connect
• Replace electrode
• Check electrodes, burners, and igniter and
re-assemble
• Replace igniter
No sparks or sound when
pressing igniter
• No battery inserted or battery inserted
incorrectly
• Battery depleted
• Igniter button not correctly tted
• Defective spark generator
• Re-insert/insert battery with correct polarity
• Replace battery
• Re-t igniter button
• Replace spark generator
Only sound (no sparks)
when pressing igniter
• Incorrect grounding
• Burner and electrode too far apart
• Re-connect spark generator and
• electrodes
• Bend electrode slightly to move it closer to
burner
Sparks visible that do not
reach burners
• Defective wiring • Replace wiring
Sparks visible but not
on all electrodes and/or not
powerful enough
• Incorrect grounding
• Battery (almost) depleted
• Wet or defective electrodes
• Re-connect spark generator and electrodes
• Replace battery
• Dry electrodes with kitchen paper or replace
electrodes
