SECTION 3: SYSTEM CONFIGURATION / JANUARY 2019 SECTION 3.0 SYSTEM CONFIGURATION 3.1 CONFIGURATION 3.1.1 INTRODUCTION This section is intended to help in the design and sizing of FlashShield™ CSST fuel gas piping systems. The form -printed on the previous page is to aid in keeping track of the system requirements as well as organizing the system configuration and sizing numbers. Refer to the Gastite website (www.gastite.com) for additional sizing tools.
SECTION 3: SYSTEM CONFIGURATION / JANUARY 2019 3.1.4 DETERMINING SYSTEM LAYOUT A) SERIES SYSTEMS Fig. 3-1 A series layout (Fig 3-1) is the most common arrangement utilized for rigid pipe systems for low pressure. These usually consist of a main run (header) with tees branching off to each appliance. In a traditional series system, the service pressure down stream of the meter is typically less than 1/2 PSI. B) PARALLEL SYSTEMS In a parallel system (Fig.
SECTION 3: SYSTEM CONFIGURATION / JANUARY 2019 D) MULTIPLE MANIFOLD SYSTEMS For those installations in which the energy load demand is large or the appliances are installed throughout the structure with long distances from the meter, a multiple manifold system may be used (Fig. 3-5, 3-6). Elevated pressure systems are a safe, efficient method of providing for larger BTUH load demands while maintaining smaller pipe diameters. Fig. 3-5 E) COMBINATION STEEL / CSST SYSTEM (HYBRID) In a hybrid system (Fig.
SECTION 3: SYSTEM CONFIGURATION / JANUARY 2019 3.1.5 ALLOWABLE PRESSURE DROP With respect to gas pipe sizing, the intent of all model codes is to ensure that there is sufficient gas volume and pressure supplied to the appliance for proper operation. Language from the International Fuel Gas Code clearly illustrates this point.
SECTION 3: SYSTEM CONFIGURATION / JANUARY 2019 Sizing for a Hybrid System (one that includes both rigid pipe and CSST) is accomplished by using the longest run method to determine the appropriate pipe size for a given load and run length. Each segment of the piping system uses the appropriate sizing table for that particular piping material. This procedure is shown in Examples 6 & 7.

SECTION 8: DEFINITIONS / JANUARY 2019 SECTION 8.0 DEFINITIONS APPLIANCE (EQUIPMENT) – Any device which utilizes gas as a fuel or raw material to produce light, heat, power, refrigeration or air conditioning. APPROVED – Acceptable to the authority having jurisdiction. ARC RESISTANT PROTECTIVE JACKET (AR) – A protective jacket over the CSST which has been tested and listed to ANSI LC1 Sec. 5.16, and ICC-ES PMG LC1027, for electrical arcing protection performance.
SECTION 8: DEFINITIONS / JANUARY 2019 LEAK TEST SOLUTION – A solution of commercial leak-testing fluids may be used. The use of soap buds or household detergents and water is not considered a satisfactory leak-test fluid for a bubble test, because of a lack of sensitivity due to masking by foam. The fluid should be capable of being applied free of bubbles so that a bubble appears only at a leak. The fluid selected should not bubble except in response to a leak.
