The Steam-N-Chips Smoker cooks with both Weber
FireSpice Wood Chips and Chunks. For best results with
faster cooking foods like steaks, burgers and chops, etc.,
we recommend using the FireSpice Chips because they
ignite and create smoke faster. For longer cooking foods
such as roasts, chicken and turkeys, etc., we recommend
using FireSpice Chunks because they ignite slowly and
provide smoke for a longer period of time. As you gain
experience in using your Steam-N-Chips Smoker, we
encourage you to experiment with different combinations of
FireSpice Chips and Chunks to find the smoke flavor that
best suits your taste.
To use the Steam-N-Chips Smoker
As a starting point, place a handful of FireSpice Chips or a
few FireSpice Chunks in the bottom of the smoker body.(1)
Since the chunks vary in size, place as many as you can in
the smoker allowing room for the water pan(2). As you gain
experience in smoking, increase or decrease the amount of
wood to suit your taste. Fill water pan, place it in the
smoker and close the smoker lid.
Cleaning the Steam-N-Chips Smoker
Before each use, empty the Steam-N-Chips Smoker of
ash to allow proper air flow.
Note - Smoking will leave a "smoke" residue on the
surface of the smoker. This residue cannot be removed
and will not affect the function of the Steam-N-Chips
Smoker. To a lesser degree a "smoke" residue will
accumulate on the inside of your Weber Gas Barbecue.
This residue need not be removed and will not adversely
affect the function of your Weber Gas Barbecue.
Note - Remove the Steam-N-Chips Smoker when it is
not in use. If it is left in the barbecue, grease and
cooking debris can accumulate on the cover.
DANGER
Do not use any flammable fluid in the
Steam-N-Chips Smoker to ignite the wood.
This will cause serious bodily injury.
Place wood in here
(2)
USING THE STEAM-N-CHIPS SMOKER
Light the barbecue and preheat with all burners on HIGH,
lid down, for 10 minutes or until the thermometer registers
260°C - 288°C. Adjust the burners for cooking; MM or LL
will be your best settings for long duration smoking. Smoke
will start in approximately 10 minutes and last as long as
45 minutes. If you require more smoke flavor, refill the
smoker with FireSpice Chips and/or Chunks and refill the
water pan with water. The Steam-N-Chips Smoker may be
used to enhance any of the meat, poultry and fish recipes
in the gas barbecue cookbook. Cook with the lid down
according to the times indicated in charts or recipes.
Note - After refilling smoker, smoke will take about 10 to
15 minutes to start again.

REFILLING THE LIQUID PROPANE CYLINDER
We recommend that you refill the LP cylinder before it is
completely empty.
Removal of the LP cylinder
1) Close cylinder valve (turn clockwise).
2) Unscrew regulator coupling by turning
counterclockwise, by hand only.
3) Loosen cylinder lock wing nut and turn cylinder lock up
out of the way.
4) Lift cylinder off.
To refill, take LP cylinder to a “Gas Propane” dealer.
WARNING: We recommend that your LP cylinder be
filled at an authorized LP gas dealer, by a qualified
attendant, who fills the cylinder by weight. IMPROPER
FILLING IS DANGEROUS.
CAUTION: When transporting the LP cylinder make
sure the plastic dust cover is in place over the valve.
This will keep dust and dirt from the threaded portion
of the valve.

IMPORTANT LP CYLINDER INFORMATION
Failure to follow these DANGER statements exactly may
result in a fire causing death or serious injury.
DANGER
NEVER store a spare LP Cylinder under or near this
barbecue.
NEVER fill the tank beyond 80% full.
Your Weber gas grill is equipped with a cylinder
supply system designed for vapor withdrawal.
WARNING: Only use this grill outdoors in a wellventilated area. Do not use in a garage, building,
breezeway or any other enclosed area.
Raises up while filling
then stops when full.
The LP cylinder supplied with your barbecue is
equipped with an OPD (Overfilling Prevention
Device) and a QCC1 or Type 1 (CGA810) cylinder
connection. The cylinder connection is compatible
with the barbecue connection.
This is a secondary device to prevent the overfilling of
your LP cylinder. The proper filling methods for the
filling of your cylinder are by weight or volume, as
described in NFPA 58. Please make sure your filling
station fills your LP cylinder by weight or volume. Ask
your filling station to read purging and filling instructions
on the LP cylinder before attempting to fill.
WARNING: Do not exchange the LP tank provided
with your barbecue, unless the exchange LP tank is
equipped with an OPD. Otherwise you will lose the
OPD (Overfilling Prevention Device) feature. If there
is not an LP tank available for exchange equipped
with an OPD, we recommend that you have your LP
tank filled at an authorized LP gas dealer by a
qualified attendant.
CONNECT FILLED LIQUID PROPANE CYLINDER
WARNING: Make sure that the cylinder valve is
closed. Close by turning clockwise.
We utilize various LP tank manufacturers. Some of the
tanks have differing top collar assembles. (The top collar
is the metal protective ring around the valve.) One series
of tanks mount with the valve facing front. The other
tanks mount with the valve facing away from the fuel
scale. These types of tanks are illustrated below.
Page 12

Hook the liquid propane cylinder onto the fuel gauge.
Loosen the cylinder lock wing nut. Swing the cylinder lock
down. Tighten the wing nut.
Remove plastic dust cover from the fuel cylinder valve.
Screw the regulator coupling onto the cylinder valve(1),
clockwise, or to the right. Hand tighten only.
Note: This is a new type of connection. It tightens
clockwise and will not allow gas to flow unless the
connection is tight. The connection requires tightening by
hand only.
WARNING: Do not use a wrench to tighten the
connection. Using a wrench could damage the
regulator coupling and could cause a gas leak.
(1)
SAFE HANDLING TIPS FOR LIQUID PROPANE GAS CYLINDERS
• Liquid Propane (LP) gas is a petroleum product as are
gasoline and natural gas. LP gas is a gas at regular
temperatures and pressures. Under moderate
pressure, inside a cylinder, LP gas is a liquid. As the
pressure is released, the liquid readily vaporizes and
becomes gas.
• LP gas has an odor similar to natural gas. You should
be aware of this odor.
• LP gas is heavier than air. Leaking LP gas may collect
in low areas and prevent dispersion.
• To fill, take the LP cylinder to an RV center, or look up
"gas-propane" in the phone book for other sources of
LP gas.
• WARNING: We recommend that your LP cylinder
be filled at an authorized LP gas dealer, by a
qualified attendant, who fills the tank by weight.
IMPROPER FILLING IS DANGEROUS.
• WARNING: If you exchange your LP cylinder,
make sure you get a similar tank in return. Your LP
cylinder is equipped with a quick closing coupling
or type 1 valve and an OPD (Overfilling Prevention
Device). Other LP cylinders may not be compatible
with your barbecue connection.
• Air must be removed from a new LP cylinder before
the initial filling. Your LP dealer is equipped to do this.
• The LP cylinder must be installed, transported and
stored in an upright position. LP cylinders should not
be dropped or handled roughly.
• Never store or transport the LP cylinder where
temperatures can reach 125° F (too hot to hold by
hand - for example: do not leave the LP cylinder in a
car on a hot day).
Note - A refill will last about 20 hours of cooking time at
normal use. The fuel scale will indicate the propane
supply so you can refill before running out. You do not
have to run out before you refill.
• Treat "empty" LP cylinders with the same care as
when full. Even when the LP tank is empty of liquid
there still may be gas pressure in the cylinder. Always
close the cylinder valve before disconnecting.
• CAUTION: When transporting the LP cylinder
make sure the plastic dust cover is in place over
the valve. This will keep dust and dirt from the
threaded portion of the valve.
• Do not use a damaged LP cylinder. Dented or rusty LP
cylinders or LP cylinders with a damaged valve may
be hazardous and should be replaced with a new one
immediately.
Liquid Propane (LP) Cylinder(s)
• The joint where the hose connects to the LP cylinder
must be leak tested each time the LP cylinder is
reconnected. For example, test each time the LP
cylinder is refilled.
• Be sure the regulator is mounted with the small vent
hole pointed downward so that it will not collect water.
This vent should be free of dirt, grease, bugs etc.
• The LP cylinder and connections supplied with your
Weber Gas Barbecue have been designed and tested
to meet government, American Gas Association, and
Underwriters Laboratories requirements.

Spider/Insect screens
Your Gas Barbecue, as well as any outdoor gas
appliance, is a target for spiders and other insects. They
can nest in the venturi section Venturi(1) of the burner
tubes. This blocks the normal gas flow, and can cause
the gas to flow back out of the air shutter. Figure 5. This
could result in a fire in and around the air shutters, under
the control panel, causing serious damage to your
barbecue.
(1)
We recommend that you inspect the Spider/Insect
screens at least once a year. Also inspect and clean
the Spider/Insect screens if any of the following
symptoms should ever occur.
1. The smell of gas in conjunction with the burner
flames appearing yellow and lazy.
2. Barbecue does not reach temperature.
3. Barbecue heats unevenly.
4. One or more of the burners do not ignite.
DANGER
Failure to correct these symptoms may
result in a fire which can cause serious
bodily injury or death and cause damage
to property.
GENERAL MAINTENANCE
Inspection and cleaning of the Spider/Insect screens
To inspect the spider/insect screens, remove the control
panel. If there is dust or dirt on the screens, remove the
burners for cleaning the screens. Refer to Maintenance,
Replacing Main Burners. Brush the spider/inspect
screens, lightly, with a soft bristle brush (i.e. an old
toothbrush).
Caution: Do not clean the spider/insect screens
with hard or sharp tools. Do not dislodge the
spider/insect screens or enlarge the screen openings.
Lightly tap the burner to get debris and dirt out of the
burner tube. Once the spider/insect screens and burners
are clean replace the burners.
If the spider/insect screen becomes damaged or cannot
be cleaned, call Weber-Stephen Products Customer
Service for replacement parts.
The burner tube air shutter is fitted with a stainless steel
screen(1) to prevent spiders and other insects access to
the burner tubes through the air shutter openings.
Liquid Propane Cylinder requirements
• Replacement LP cylinders supplied by Weber satisfy
the above requirements. Check to be sure other
cylinders have a D.O.T. certification(1), and date
tested(2) is within five years. Your LP gas supplier can
do this for you.
If you have questions about spare LP cylinders
DOT 4BA240

If the flames do not appear to be uniform throughout the
burner tube, follow the burner cleaning procedures.
Main Burner Cleaning Procedure
Turn off the gas supply. Remove the manifold.
Look inside each burner with a torch.
Clean the inside of the burners with a wire (a
straightened-out coat hanger will work). Check and clean
the air shutter opening at the ends of the burners. Check
and clean the valve orifices at the base of the valves. Use
a brass bristle brush to clean outside of burners. This is
to make sure all the burner ports are fully open.
CAUTION: Do not enlarge the burner ports when
cleaning.

Crossover® Ignition System Operations
If the Crossover Ignition System fails to ignite the Left
burner, light the Left burner with a match. If the Left
burner lights with a match, then check the Crossover
Ignition System.
• Check that both the white(1) and black(2) ignition
wires are attached properly.
• Check that the Crossover Ignition button pushes the
igniter (button) down, and returns to the up position.
• Check to see if the igniter is loose in the frame.
Tighten if necessary; See Step “Install igniter” for
correct procedure.
If the Crossover Ignition System still fails to light, Contact
the Customer Service Representative in your region using
the contact information sheet provided with your manual.

Problem
Burners burn with a yellow or orange flame,
in conjunction with the smell of gas.
Burner does not light, or flame is low in
HIGH position.
Experiencing flare-ups:
CAUTION: Do not line the bottom tray
with aluminum foil.
Burner flame pattern is erratic. Flame is
low when burner is on HIGH. Flames do
not run the whole length of the burner tube.
Inside of lid appears to be “peeling.”
(Resembles paint peeling.)
Barbecue seems to lose heat when
cooking in cold weather temperatures
50° F or colder. (The liquid propane in the
cylinder turns to vapor too slowly to
supply the burners with gas.This is due to
the air temperature cooling the LP cylinder
which slows the vaporization process.)
Check
Inspect Spider/Insect Screens for
possible obstructions. (Blockage
of holes.)
Is LP fuel low or empty?
Is fuel hose bent or kinked?
Does the Left burner light with a
match?
Are you preheating barbecue in the
prescribed manner?
Are the cooking grates and
Flavorizer Bars heavily coated with
burned-on grease?
Is the bottom tray "dirty" and not
allowing grease to flow into catch pan?
Are burners clean?
The lid is porcelain-on-steel, not
paint. It cannot “peel.” What you
are seeing is baked on grease that
has turned to carbon and is flaking
off. THIS IS NOT A DEFECT.
Is there frost/ice on the outside of
the LP cylinder?
Cure
Clean Spider/Insect Screens and
inspect burners. (See Maintenance
Section.)
Refill LP tank.
Straighten fuel hose.
If you can light the Left burner with
a match, then check the Crossover
Ignition System.
All burners on high for 10 to 15
minutes for preheating.
Clean thoroughly. (See Cleaning
Section.)
Clean bottom tray.
Clean burners. (See Maintenance
Section.)
Clean thoroughly. (See Cleaning
Section.)
Turn off burner control knobs and
the LP cylinder. Replace with a
spare LP cylinder and resume
cooking.
WARNING:The spare or
disconnected LP cylinder must
be stored outdoors in a well
ventilated area out of the reach
of childeren. The spare or
disconnected LP cylinder must
never be stored under or near
your Weber Gas Barbecue.
