INSTALLATION OF CATCH PAN INTO BOTTOM TRAY

Slide the bottom tray onto the mounting rails under the
cooking box with finger grip toward you.

CAUTION: Do not line bottom tray with aluminum foil.
It can cause grease fires by trapping the grease and
not allowing grease to flow into the catch pan.

Put the foil drip pan into the catch pan.
Slide the catch pan into the catch pan holder with its

finger grip towards you.

Smoker so it opens towards Flavorizer bars.

Note: Remove any tape or packing material. Parts are
shipped in place. Use these steps to check that they are
in position. The Flavorizer bars are already in place.

This step is only for reinstallation.

Set the long stainless steel Flavorizer bars side to side in
the lower position of the cooking box. Insert the front two
Flavorizer bars through the Steam-N-Chips Smoker flue.

SET LP FUEL SCALE

You will need: LP tank (empty).

Note - For accuracy, the fuel scale must be set with an
empty tank.

We utilize various LP tank manufacturers. Some of the
tanks we receive have differing top collar assemblies.
(The top collar is the metal protective ring around the
valve.) One series of tanks mounts with the valve facing
front. The other tanks mount with the valve facing away
from the fuel scale. These types of tanks are illustrated in
Figure 9.

Loosen the tank lock wing nut. Tighten so the lock is held
up out of the way. Figure 9 (a). Lift and hook the tank onto
the fuel scale. With an empty LP tank, adjust the fuel scale
setting to E with scale setting (top) wing nut. Figure 9 (b).

CAUTION: Do not remove adjustment wing nut from
tank scale.

After adjusting tank scale, push tank down a couple of
times to check that the tank scale is set on “E”.

FILL LP TANK

To fill, take the LP tank and filler adapter 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 tank be filled
at an authorized LP gas dealer by a qualified
attendant, who fills the tank by weight.

IMPROPER FILLING IS DANGEROUS.

Tell your LP dealer that this is a new LP tank. The air
must be removed from a new LP tank before the initial
filling. Your LP tank dealer is equipped to do this.

CAUTION: If you exchange your LP tank, make sure
you get a similar tank in return.Your LP tank is
equipped with a Type II, CGA #810 quick-disconnect
valve. Other LP tanks are not compatible with your
barbecue connection.

The LP tank must be installed, transported and stored in
an upright position. LP tank should not be dropped or
handled roughly.

Never store or transport the LP tank where temperatures
can reach 125° Fahrenheit (too hot to hold by hand – for
example: do not leave the LP tank in a car on a hot day).

For full instructions on safe handling of LP tanks, see
Section "General Tank Information”.

GENERAL TANK INFORMATION

LP Tank Manufacturer

The LP tank manufacturer is responsible for the materials,
workmanship and performance of the tank. If the tank has
a defect, malfunctions, or you have a question regarding
the tank, call the tank manufacturer's customer service
center. The phone number is on the warning decal which is
permanently attached to the tank. If the tank manufacturer
has not resolved the issue to your satisfaction, then call
Weber-Stephen Products Co., Customer Service Center.

For Y our Safety

Your LP tank is shipped empty for safety. After setting the
LP fuel scale you will need to fill it. Refer to Filling your
LP tank.

Safe handling tips for LP Gas

■ 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, LPgas 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
know this odor.

■ LP gas is heavier than air. Leaking LP gas may
collect in low areas that prevent dispersion.

■ The LP tank must be installed, transported and stored
in an upright position. LP tanks should not be
dropped or handled roughly.

■ Never store or transport the LP tank where
temperatures can reach 125° F (too hot to hold by
hand - for example: do not leave the LP tank in a car
on a hot day).

■ The LP cylinder supply must be arranged for vapor
withdrawal.

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 tanks 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 tank valve before disconnecting.

■ Do not use a damaged LP tank. Dented or rusty LP
tanks or LP tanks with a damaged valve may be
hazardous and should be replaced with a new one
immediately.

■ The joint where the hose connects to the LP tank
must be leak tested each time the LP tank is
reconnected. For example, test each time the LP tank
is refilled.

■ Be sure the regulator is mounted with the small vent
hole pointed downward so it will not collect water.
This vent should be free of dirt, grease, bugs etc.

■ The LP tank and connections supplied with your
Weber Gas Barbecue have been designed and tested
to meet government, American Gas Association and
Underwriters Laboratories requirements.

■ Replacement LP tanks supplied by Weber satisfy the
requirements. Check to be sure the tank has a D.O.T.
certification, and has been tested within five years.
Your LP gas supplier can do this for you. Figure 10.

If you have questions about spare LP tanks, please
call Weber-Stephen Customer Service.

DOT 4BA240

2/96

Date Tested

D.O.T. Certification (example)

■ All LP tank supply systems must include a collar to

■ The LP tank must be constructed and marked in
accordance with the specifications for LP gas
cylinders of the U.S. Department of Transportation
(D.O.T.).

CHECK FOR GAS LEAKS

WARNING

The gas connections of your Weber Gas
Barbecue have been factory tested. We do
however recommend that you leak check all
gas connections before operating your
Weber Gas Barbecue.

Remove the knobs from the control panel. Figure 27.

Figure 28

Figure 27

Use a Phillips screwdriver to remove the screws from the
underside of the control panel. Figure 28.

Stand at the right end of the barbecue. Lift the control
panel off. The side burner or work surface remains
in place.

View from right

underside

WARNING: You should check for gas leaks every time
you disconnect and reconnect a gas fitting.

You will need: a soap and water solution and a rag or
brush to apply it.

Note - Since some leaks test solutions, including soap
and water, may be slightly corrosive, all connections
should be rinsed with water after checking for leaks.

DANGER

Do not use an open flame to check for
gas leaks. Be sure there are no sparks or
open flames in the area while you check for
leaks. This will result in a fire or explosion
which can cause serious bodily injury or
death and damage to property.

Figure 29

To perform leak checks: open tank valve by turning the
tank valve handwheel counterclockwise. Figure 29.

WARNING

Make sure all burner control knobs are in
the OFF position, including the side burner,
if the barbecue has a side burner.

16

CHECK FOR GAS LEAKS

WARNING: Do not ignite burners while checking
for leaks.

Check for leaks by wetting the connections with the soap
and water solution and watching for bubbles. If bubbles
form or if a bubble grows there is a leak.

Check:
a) Hose to manifold connection. Figure 30 (a).

WARNING: If there is a leak at connection a, retighten
the fitting with a wrench and recheck for leaks with
soap and water solution.

If a leak persists after retightening the fitting, turn
OFF the gas. DO NOT OPERATE THE BARBECUE.
Contact Weber-Stephen Customer Service.

b) Regulator to tank connection. Figure 30 (b).
c) Manifold to side burner hose connection.

g) Hose to regulator connection. Figure 30 (g).

WARNING: If there is a leak at connections
b, c, d, e, f or g, turn OFF the gas. DO NOT OPERATE
THE BARBECUE. Contact W eber-Stephen
Customer Service.

When leak checks are complete, turn gas supply OFF at
the source and rinse connections with water.
