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 12.
Loosen the tank lock wing nut. Tighten so the lock is held
up out of the way. Figure 12 (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 12 (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.
WARNING: If you exchange your LP tank, make
sure you get a similar tank in return.Your LP tank is
equipped with a quick-disconnect valve and an OPD
(Overfilling Prevention Device). 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.
ForYour 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, 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
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 tested for leaks 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 13.
If you have questions about spare LP tanks, please
call Weber-Stephen Customer Service.

D.O.T. Certification (example)
■All LP tank supply systems must include a collar to
protect the tank valve.
■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.).
■The LP tank shipped with your barbecue is equipped
with an OPD (Overfilling Protection Device).
