Weber 5500 owner manual General Specifications for Piping

Notice Before Installation

Contact your local municipality for any building codes regulating outdoor barbecue installations. In absence of

local codes, you must conform to the latest edition of ANSI Z223.1.

WE RECOMMEND THAT THIS INSTALLATION BE DONE BY A PROFESSIONAL.

General Specifications for Piping

American National Standards Institute (ANSI) Recommendations for gas supply installations: Connections:

■This barbecue is designed to operate at 7 inches of water column pressure (.2526 psi).

■A manual shut-off valve must be installed outdoors, immediately ahead of any connections or change in pipe material.

CAUTION: If young children are in the area, a locking valve should be considered.

■An additional manual shut-off valve indoors should be installed in the branch fuel line in an accessible location near the supply line.

■The point of tie into the branch line should be carefully selected to avoid a drip leg or be downstream of a valve controlling another appliance.

■Pipe compound should be used which is resistant to action of natural gas when connections are made.

■The outdoor connector must be firmly attached to rigid, permanent construction.

Outside underground piping

Outside underground piping may be copper tubing, type K or L (ASTM B88) or polyethylene plastic tube PE3306 (Minimum wall thickness .062") meeting ASTM 2513, latest specifications.

Steel pipe is not recommended for underground use unless it is protected with an approved coating, insulated from hose piping and cathodically protected.

It is recommended that copper tubing be corrosion protected with a satisfactory material such as TC Mastic.

All buried fittings should be corrosion protected with a satisfactory material such as TC Mastic.

Underground piping must have a minimum of 10" cover.

Plastic tubing

Plastic tubing is suitable only for outside underground use.

■The transition from metallic pipe to plastic pipe should be made outside and at least 10" underground.

■When compression or crimp type mechanical joints are used with plastic pipe, it is advisable to use an internal rigid stiffener in conjunction with the fitting.

■The stiffener should be assembled flush with the end of the tube and extend at least to the outside edge of the compression fitting.

Gas line piping

■If the length of line required does not exceed 50 feet, use a 5/8" O.D. tube. One size larger should be used for lengths greater than 50 feet.

■Indoor and above ground piping can be steel or copper.

Testing connections

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

All connections and joints must be thoroughly tested for leaks after gas has been turned into the line.

Steel

New standard weight (Schedule 40) steel pipe with malleable iron fittings.

Copper

New copper tubing type K or L.

Copper tubing must meet requirements of ASTM B88 latest edition.

Use flared fittings. Metallic ball sleeve compression fittings must not be used.

Copper tube joints may be soldered or brazed with material having a melting point in excess of 1,000°F.

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 gas leaks. This will result in a fire or explosion which can cause serious bodily injury or death, and damage to property.

Wet the fitting with a soap and water solution. Any bubbles that form or grow indicate a leak. If bubbles occur shut off gas, tighten the fitting, and retest.

WARNING: If a leak persists after tightening the fitting, turn gas off at the supply. DO NOT OPERATE YOUR BARBECUE. Contact your dealer.
