Napoleon LEX Series Manual page 13

Problem
Burners will not cross
light each other.
"Paint" appears to
be peeling inside lid
or hood.
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.)
N415-0434 MAY 28.18
Possible Causes
Dirty or corroded cross light
brackets.
Grease build-up on inside
surfaces.
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
Clean or replace as required.
This is not a defect. The finish on the lid and
hood is porcelain, and will not peel. The
peeling is caused by hardened grease, which
dries into paint-like shards, that flake off.
Regular cleaning will prevent this. See cleaning
instructions.
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.
