Burner Adjustments
Every burner is tested and adjusted at the factory for proper performance. If a burner
is not operating properly, it may be due to variations in the local gas supply or because
of an obstructed air shutter or orifice. Flames should be stable without lifting from the
burner. The flames should burn cleanly without creating any sooty residue.
BURNER FLAME CHARACTERISTICS:
•
The flame should be mostly blue and stable with only a small amount of orange, if
any, at the tips. There should be little noise and no lifting. A muffled “pop” when
the burner is turned off is normal.
•
The inner cone should be 1/4 inch (6.4 mm) high.
•
The outer cone should be 5/8 inch (15.9 mm) high.
Visually inspect the flames in your grill and adjust if necessary, using the instructions
below.
IMPORTANT:
A sooty flame is usually caused by dirt, debris or spider nests blocking the
air shutter or orifice. This is a dangerous condition. The grill should NOT be used until
the problem is rectified. If you are not comfortable addressing the issue yourself,
please hire a licensed technician or contact Crown Verity Service at 1-888-505-7240.
TO CLEAN THE AIR SHUTTER:
Turn off the gas supply shutoff valve or close the main valve on the LP cylinder. Ensure
the grill control knobs are in the OFF position. Be sure that the unit is cool.
Next, remove the grates. They are heavy and care should be taken in removing them,
so they do not damage the outer surface of the appliance.
Next, remove the faceplate of the burner box by first removing all of the knobs and
then removing the screws holding the face in place (See “Figure 16”). Once the screws
are removed, gently lift the face up and forward to remove. If the grill is equipped
with a light package, disconnect the wire harness from the individual burner bezels as
well as the two switch connections. Place the face down on its back to avoid surface
scratches.
