Weber SUMMIT FS38 E - Gas Flow and Flame Pattern Problems; Gas Smell and Spider Screen Issues

11
Troubleshooting
GAS FLOW
SYMPTOM
• Grill does not reach desired temperature or heatsunevenly.
• One or more of the burners fail to ignite.
• Flame is low when burner is on high position.
• Flames do not run the whole length of the burner.
• Burner flame pattern is erratic.
CAUSE SOLUTION
The “flow limiting device” has been activated. Thissafety
feature built into the regulator restricts the gas flow in
the event of a gas leak. You can inadvertently activate this
safety feature without having a gas leak. This typically
occurs when you turn on the gas at the LP tank and one or
more of the control knobs are not in the o position. It may
also occur if you turn on the LP tank too quickly.
Reset the “flow limiting device” by closing the LP tank
valve and turning all the burner control knobs to the
o position. Wait five minutes to allow accumulated
gas to dissipate, then ignite the grill again following the
instructions in the “Operation” section.
The LP tank is low or empty. Refill LP tank.
Fuel hose is bent or kinked. Straighten fuel hose.
Burner ports are dirty. Clean burner ports. Refer to “Cleaning the BurnerPorts.”
SYMPTOM
• Gas is smelled in conjunction with burner flames that appear yellow andlazy.
CAUSE SOLUTION
Spider screens on the burners are obstructed. Clean spider screens. Refer to “Cleaning the Spider
Screens” in the Product Care section. Also refer to the
illustrations and information in this section about proper
flame pattern and spiderscreens.
SYMPTOM
• The smell of gas and/or a light hissing sound.
CAUSE SOLUTION
The internal rubber seal in the LP tank valve could be
damaged.
Extinguish any open flame. Shut o gas to the appliance
(grill). Inspect the rubber seal for damage. If damaged,
return tank to place of purchase.
Connection between regulator and LP tank could be
incomplete.
Extinguish any open flame. Shut o gas to the appliance
(grill). Refer to LP TANK INSTALLATION & LEAK
CHECKING section of your owner’s manual.
Proper Burner Flame Pattern
The burners in your grill were factory set for the
correct air and gas mixture. When the burners are
performing correctly, you will see a specific flame
pattern. The tips may occasionally flicker yellow
(A), with a descending light blue (B) to dark blue
flame (C).

m WARNING: Do not attempt to make any repair to
gas carrying, gas burning, ignition components
or structural components without contacting
Weber-Stephen Products LLC, Customer Service
Department.
m CAUTION: The burner tube openings must be
positioned properly over the valve orifices.
Spider Screens
The combustion air openings of the burners(D)
are fitted with stainless steel screens to prevent
spiders and other insects from spinning webs
and building nests inside the venturi section of
the burners. These nests can obstruct the normal
gas flow, and can cause gas to flow back out of the
combustion air opening. Symptoms of this kind of
obstruction include the odour of gas in conjunction
with burner flames that appear yellow and lazy.
This obstruction could result in a fire in and around
the gas valve, causing serious damage to your grill.
Additionally, dust and debris can accumulate on the
outside of the spider/insect screen and obstruct the
oxygen flow to the burners. Keep the spider screens
clean. Refer to “Cleaning the Spider Screens” in the
Product Care section.
