should not need adjusng under normal condions. Under extreme eld condions, adjustments might be
required. When the air shuer is adjusted correctly the ames will be dark blue, pped with light blue and
occasionally yellow.
• With too lile air ow to the burner, the ames are lazy yellow and can produce soot.
• With too much air ow, the ames li erracally and can cause dicules when lighng.
Adjusng the air shuer:
1. Remove cooking grids and sear plates and leave lid open. The back cover must be removed for rear tube
burner air shuer adjustment.
2. Loosen air-shuer lock screw located at the mouth of the burner and open or close air shuer as required.
The normal opening sengs are:
Main Tube Burner Propane 3/16” (5mm) Rear Tube Burner Propane 3/8” (10mm)
Natural 1/8” (3mm) Natural 1/8” (3mm)
*Infra-Red burners have no air adjustment.
3. Light the burners and set to high. Visually inspect burner ames. When the shuers are set correctly, turn
burners o, ghten locking screws, and replace removed parts. Ensure that the insect screens are installed.
: The burner is made from heavy wall 304 stainless steel, but extreme heat and a corrosive environment
can cause surface corrosion to occur. This can be removed with a brass wire brush.

Spiders and insects are aracted to the smell of propane and natural gas. The burner is equipped with an insect screen on
the air shuer, which reduces the likelihood of insects building nests inside the burner but does not enrely eliminate the
problem. A nest or web can cause the burner to burn with a so yellow or orange ame or cause a re (ashback) at the air
shuer underneath the control panel. To clean the inside of the burner, it must be removed from the gas grill: Remove the
screw (s) that aaches the burner to the back wall. Slide the burner back and up wards to remove.
: Use a exible venturi tube brush to clean the inside of the burner. Shake any loose debris from the
burner through the gas inlet. Check the burner ports and valve orices for blockages. Burner ports can close
over me due to cooking debris and corrosion, use an opened paperclip or the supplied port maintenance bit
to clean them. Drill out blocked ports using this drill bit in a small cordless drill. The ports are easier to clean
if the burner is removed from the grill, but it can also be done with the burner installed. Do not ex the drill
bit when drilling the ports, as this will cause the drill bit to break. This drill is for burner ports only, not for the
brass orices (jets) which regulate the ow into the burner. Take care not to enlarge the holes. Ensure the
insect screen is clean, ght, and free of any lint or other debris.
: Reverse the procedure to reinstall the burner. Check that the valve enters the burner when
installing. Replace sear plate mount and ghten screws to complete reinstallaon.
