Should I replace the flexible line from the shut-off valve to the stove? All CSST products have to pass tests for safety and performance before they can be sold in the U.S. market. Reducing the number of fittings is beneficial as each additional joint needs to be fitted and checked for leaks. Most CSST fittings form a metal-to-metal seal between the brass fitting and stainless steel pipe. c) In many applications, the CSST is sized for individual gas appliance loads and is, therefore, usually small in diameter. Trac-pipe fittings can be reused. CSST. Compression fittings are used to make transitions between pipes. A CSST gas piping system has less joints, and therefore less potential leak paths. These are distances of piping runs, appliance loads, and supply pressure. While FlashShield CSST shares many of the same fitting assembly and installation guidelines as our standard CSST, there are a few important differences. This expansive standard covers the installation, manufacture and testing of tubing and fittings. CSST can be piped in parallel from a distribution manifold and in series like common steel pipe sys-tems. Most can be reused if there is no pre-sealant on the fittings. I read in the manual that this can be reused up to 4 times.-I have moved the stove in and out several times in the process. The bonding jumper shall connect to a metallic pipe or fitting between the point of delivery and the first downstream CSST fitting . HOME-FLEX CSST has been tested and certified by CSA and IAPMO for compliance with the industry standard ANSI LC-1 / CSA 6.26, “Fuel Gas Piping Systems using Corrugated Stainless Steel Tubing (CSST… The idea for the corrugations is that as the flexing hardens it in one spot, the next one can take up the movement. Here’s how they work: First, use a steel tubing cutter to cut the pipe to length along a valley in the corrugation. Gas piping systems The bonding jumper shall not be smaller than 6 AWG copper wire or equivalent. It even covers the certification of qualified installers. They go together with the two piece ring set one section back from the cut (it must be clean, straight and no burrs) the nut is placed on the tubing first, then the two ring halves go in … Yes. CSST gas piping systems shall be bonded to the electrical service grounding electrode system. ANSWER: CSST was first introduced in … Corrugated Stainless Steel Tubing, or CSST, is a flexible tubing used to supply natural gas and propane in buildings. Re: Why not reuse flare/flex gas connection pipe? Everything seemed relatively straighforward, but never having worked with CSST and these fittings, I would like some feedback. This bulletin is intended as a quick summary of those differences, and is not intended to replace our official installation guide. Easy-to-use software TracPipe ® CounterStrike ® Specifier for Windows version 3.5 is available for download in the Technical Information section of this website. d) The small diameter CSST is suitable for use with elevated pressure systems (above 1/2 psi up to 5 psi). Author: hj (AZ) When you move the appliance, the flex can bend wherever necessary. CSST was introduced here in 1990 following the adoption of ANSI standard LC-1 in 1989. (back to top) QUESTION: When was CSST first introduced into homes? In fact, Gastite ® CSST can be installed with just simple hand tools such as a tubing cutter, wrench and utility knife and because the patented Jacket-Lock ® fitting eliminates exposed stainless steel, it ensures that all cuts are neat and tidy. Can TracPipe ® CounterStrike ® fittings be concealed? Each manufacturer of CSST will provide a range of fittings allowing its CSST to be joined to rigid materials or, if required, to join CSST to CSST – manufacturers’ fittings are not interchangeable. -I reused the split ring.
