Check And Adjust Burner - Nexgrill 710-0778A Instrucciones De Instalación Y Manual De Uso Y Cuidado

The burners are tested and factory-set for most efficient
operation. However, variations in gas supply and other
conditions may make minor adjustments to air shutter or
low flame setting necessary.
It is recommended that a qualified technician make burner
adjustments.
NOTE: The rotisserie burner cannot be adjusted.
Checking and adjusting the grill burner flames requires
removing the grates and flame tamers.
Burner Flame Characteristics
The flames of the grill burners and side burners (on some
models) should be blue and stable with no excessive noise
or lifting (LP gas flames will have a slightly yellow tip). A
yellow flame indicates not enough air. If flame is noisy or
lifts away from the burner, there is too much air. Some
yellow tips on flames when the burner is set to HIGH
setting are acceptable as long as no carbon or soot
deposits appear. The flames should be approximately 1"
(2.5 cm) high.
Check that burners are not blocked by dirt, debris, insect
nests, etc., and clean burners as necessary. If they are clean,
adjust air shutters as needed.
IMPORTANT: Before adjusting air shutters, let burners cool
completely.
To Adjust:
1.Light grill using information in the "Outdoor Grill Use"
section.
2.Observe flame to determine which burners need adjustment
and how the flame is acting.
3.Turn off the valve and wait until grill and burners cool
completely.
4.Remove grill grates and flame tamers.
5.Remove the screw and cotter clip that hold the burner in
place. Remove gas burner from the grill.
