2. Beginning with the Infrared Rotisserie Burner in the upper canopy area of the grill, access the
spud orifice shown in the image below. Disconnect the flex hose first. Then use a wrench to
hold the brass elbow steady, while using another wrench to remove the lock-nut. You may now
remove the elbow out of the burner bracket. Try not to disturb the flex hose connection by
unduly bending it too much. Be careful not to damage the wires and copper thermocouple tube
nearby.
1. Open your grill and remove the grates, radiant trays, and burners from the firebox area. Open
flame burners (Trellis burners in Hestan Grills, and U-Burners in Aspire Grills) are removed by
lifting up the rear of the burner, and carefully twisting to clear the igniter shroud. Sear burners
have a small metal cover over the igniter which must be removed first. There is also a screw at
the rear firebox wall which must be removed. The sear burner can then be carefully removed
using the same twisting action to avoid breaking the ceramic igniter. Remove the rear cover of
the grill. If your grill is mounted on a cart, remove the rear access panel of the cart as well. Also
remove the control knobs and drip pan.
