Problem
Burner output on "high"
setting is too low.
(Rumbling noise and
fluttering blue flame at

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.)
N415-0326 JAN 26.18
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.
