CLEANING FOR SAFETY
m
DANGER
Failure to correct any problems described
on this page may result in a fire, which can
cause serious bodily injury or death, and
cause damage to property.
CLEANING THE
BURNER TUBES
Over time, with repeated use,
your grill may show symptoms
that it needs a more thorough
cleaning. Some of these
symptoms are:
• Grill does not reach desired
temperature
• Grill heats unevenly
• One or more of burners fail
to ignite
• Smell of gas and improper
flame pattern
These symptoms arise
because the burner tubes
need extra care. It is essential
to clean the burner tubes to
keep your grill performing as
safely and efficiently as on day
one.
Two areas on the burner tubes that are key to optimum
performance are the ports (small openings running along
the length of the burner tubes) and the spider/insect
screens on the ends of the burner tubes. Keeping these
areas clean is essential for safe operation.
The burner tubes in your Weber grill were factory set for
the correct air and gas mixture. When the burner tubes
are performing correctly, you will see a specific flame
pattern. The tips may occasionally flicker yellow (1), with
a descending light blue (2) to dark blue flame (3). If the
flames do not match the above flame pattern description,
it could be a indication that the burner ports and/or
spider/insect screens need cleaning.
Below is important information about the maintenance of
these two key components of the burner tubes.
CLEAN THE BURNER TUBE PORTS
Over time, from repeated use of the grill, the burner tube
ports (4) may become dirty and blocked. Blocked and dirty
ports can restrict full gas flow. This obstruction could
result in a fire (5) in and around the gas valves, causing
serious damage to your grill
Common symptoms of blocked or dirty ports may include:
• Grill does not reach desired temperature
• Grill heats unevenly
• One or more of the burners fail to ignite
• Gas is smelled in conjunction with some or all of the
ports not lighting.
Note: The above symptoms can also be a sign that the
“excess gas flow control” feature has activated. Refer back
to “MAIN BURNER IGNITION” to reset the excess flow safety
device.
You will need: A clean stainless steel bristle grill brush.
Do not use a brush that has already been used to clean
the cooking grates.
A) Confirm that grill is off and cool.
B) Remove cooking grates and Flavorizer
®
bars.
C) Use the brush to clean the outside of the burner tubes
and the Crossover
®
tube (6). Do not brush lengthwise
along the tube, as this will only push debris from one
hole to another. Note that the burner tubes will move
slightly, as if they are loose, this is normal.
D) When cleaning burner tube 1, avoid damaging the
igniter electrode by carefully brushing around it (7).
m
CAUTION: Do not enlarge the burner
tube ports and do not use sharp objects
to clear the ports individually.
E) Continue onto cleaning the spider/insect screens.
