Napoleon PRESTIGE II 308 Manual De Instrucciones página 11

Problem
Burner output on "high"
setting is too low. (Rumbling
noise and fluttering blue
flame at burner surface.)
Infrared burner (if equipped)
flashes back (during
operation the burner
abruptly makes a loud
"whoosh" sound, followed by
a continuous blow-torch type
sound and grows dim.)
Possible Causes
Lack of gas.
Supply hose is pinched.
Dirty or clogged orifice.
Spider webs or other matter
in venturi tube.
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.
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.
