Possible Causes
Lack of gas.
Supply hose is pinched.
Dirty or clogged orifice.
Spider webs or other matter in venturi
tube.
Propane regulator in "low flow" state.
Ceramic tiles overloaded with grease
drippings and build-up. Ports are
clogged.
Burner overheated due to inadequate
ventilation (too much grill surface
covered by griddle or pan.)
Cracked ceramic tile.
Leaking gasket surrounding the ceramic
tile, or a weld failure in the burner
housing.
Solution
Check gas level in propane cylinder.
Reposition supply hose as necessary.
Clean burner orifice.
Clean out venturi tube.
Ensure lighting procedure is followed carefully.
All gas grill valves must be in the off position
when the tank valve is turned on. Turn tank
on slowly to allow pressure to equalize. See
lighting instructions.
Turn burner off and allow to cool for at least
two minutes. Relight burner and burn on high
for at least five minutes or until the ceramic
tiles are evenly glowing red.
Ensure that no more than 75% of the grill
surface is covered by objects or accessories.
Turn burner off and allow to cool for at least
two minutes, then relight.
Allow burner to cool and inspect very closely
for cracks. If any cracks are found, contact
your authorized Napoleon dealer to order a
replacement burner assembly.
