STANDARDS AND CODES INFORMATION

REFER TO YOUR STEP-BY­STEP GUIDE AT THIS TIME
FOR BARBECUE ASSEMBLY

WA R N I N G : Make sure your barbecue is set up pro p e r ly
and leak ch e cked before attempting to operate.

Your Weber Gas Barbecue is a portable outdoor cooking
appliance. With the Weber Gas Barbecue you can grill,
barbecue, roast and bake with results that are difficult to
duplicate with indoor kitchen appliances. The closed lid and
Flavorizer Bars produce that "outdoor" flavor in the food.

The Weber Gas Barbecue is portable so you can easily
change its location in your yard or on your patio.
Portability means you can take your Weber Gas
Barbecue with you if you move.

The natural gas supply is easy to use and gives you more
cooking control than charcoal fuel.

■ These instructions will give you the minimum

requirements for operating and maintaining your
Weber Gas Barbecue. Please read the instructions
carefully before using your Weber Gas Barbecue.
Improper assembly can be dangerous.

■ Not for use by children.

■ If there are local codes that apply to portable gas

grills, you will have to conform to them. If there are no
local codes, you must conform to the latest edition of
the National Fuel Gas Code: ANSI Z 223.1.

■ This Weber Gas Barbecue is designed for natural

(piped in city) gas only. Do not use Liquid Propane
(LP) bottled gas.The valves, orifices and hose are for
natural gas only.

■ Do not use with charcoal fuel.

■ Use the natural gas regulator supplied with the barbecue.

USING THE STEAM-N-CHIPS SMOKER

The Steam-N-Chips Smoker cooks with both We b e r
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.
Figure 4. Since the chunks vary in size, place as many as
you can in the smoker allowing room for the water pan. A s
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.

Do not use any flammable fluid in the
Steam-N-Chips Smoker to ignite the wo o d .
This will cause serious bodily injury.

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
s u r face of the smoke r.This residue cannot be remove d
and will not affect the function of the Steam-N-Chips
S m o ke r.To a lesser degree a "smoke" residue will
a c c u mulate on the inside of your Weber Gas Barbecue.
This residue need not be removed and will not adve r s e l y
a f fect the function of your Weber Gas Barbecue.

DA N G E R

Steam-N-Chips Body

Place wood in here

Figure 4

Light the barbecue and preheat with all burners on HIGH,
lid down, for 10 minutes or until the thermometer registers
500°F - 550°F. 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 smoke r, smoke will take about 10 to
15 minutes to start again.

MAINTENANCE

We recommend that you inspect the Spider Stopper
G u a rds at least once a ye a r. Also inspect and clean the
Spider Stopper Guards if any of the fo l l ow i n g
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.

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 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.

Venturi

Air shutter

Figure 5

The Spider Stopper Guard is factory installed. It fits tightly
around the air shutter section of the burner tube and the
valve, thereby preventing spiders and other insects
access to the burner tubes through the air shutter
openings. Figure 6.

DANGER

Failure to correct these symptoms may
result in a fire which can cause serious bodily
i n j u ry or death and cause damage to pro p e rt y.

Inspection and Cleaning of the Spider
Stopper Guards

To inspect the Spider Stopper Guards, remove the control
panel and look to see if they have dust or dirt on their
outside surfaces. If they are dirty, brush off the outside
surface of the Spider Stopper Guards with a soft bristle
brush (an old toothbrush for example). Check that there
are no gaps in the Spider Stopper Guards’ seams or in
the fit around the burners or valves.

MAINTENANCE

Main Burner Cleaning Procedure

Turn off the gas supply. Remove the manifold.

Look inside each burner with a flashlight. Figure 8.

Clean the inside of the burners with a wire (a straightened
out coat hanger will work). Figure 9. 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.

C AU T I O N: Do not enlarge the burner ports when cl e a n i n g .

TROUBLESHOOTING

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.)

Check

Inspect Spider Stopper Guards for
possible obstructions. (Blockage of
holes.)

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.

Cure

Clean Spider Stopper Guards.
(See Maintenance Section.)

Straighten fuel hose.

If you can light the Left burner
with a match, then check the
Crossover Ignition System.
(See Maintenance Section.)

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.)

If the problem cannot be corrected using these methods, please contact your Weber-Stephen Customer Service.
