Maintenance
• A normal flame is blue and may have orange tips. If the flame is completely yellow adjust the ventilation plate bigger or
smaller until the flame burns blue.
• To adjust the ventilation, use a screwdriver to loosen the screw holding the ventilation in place indicated below. Adjust
ventilation to desired air flow and return screw to the secured position.
• If the flame does not turn blue it could be that the venture tube has an obstruction, or the jet is not securely fitted. If the jet
gets blocked, do not try to clean the blockage. It must be replaced with the appropriate jet. Your local approved gas dealer
or Cobb agent will be able to replace this.
• This appliance must only be serviced by an authorized person.
• Please note that any grill in storage can become a target for spiders and other insects. They can nest in the venturi section of
the burner tube which in turn may block the standard gas flow, causing the gas to flow back out of the air shutter. This could
result in a fire in or around the air shutter and has the ability to cause damage to your Cobb Gas. We recommend
that you inspect the Burner Tube annually, or when the unit is not used regularly.
