Do you have to ground CSST gas line?
CSST flexible gas piping must be bonded to reduce the risk of damage due to a lightning strike on the home. The most common issue that home inspectors find is the CSST system is not being properly bonded. You can see that the bonding clamp is over the yellow sheathing which will not enable a proper bond.
How do I ground my gas line?
Grounding means connection of a copper wire, often bare copper – to your gas line, then connecting the other end to your homes grounding system. National Electrical Code requires all homes to have a grounding system. This system consists of a ground rod (8′) driven in the ground close to your electric meter.
When should I ground CSST?
CSST needs to be bonded. If CSST is installed without being properly bonded to current standards, you have an increased risk for damage to the material from a nearby lightning strike. If CSST is damaged, it can leak gas and cause an explosion and/or a fire.
How much does it cost to ground CSST?
How Much Does It Cost? As with most electrical repairs the cost can vary significantly based on many factors, but a good rule of thumb would be between $150 – $500 for most single-family homes in Central Iowa.
Can you ground a gas line to a ground rod?
ANSWER: Yes, I said metal gas piping should be bonded to the supply system grounded conductor. Section 250-104(b) does require that metal gas piping should be bonded to the grounding electrode system. This can be done by terminating at the neutral bar, or any of the electrodes in the grounding electrode system.
Where do you bond the gas pipe?
Corrugated stainless steel tubing (CSST) gas piping systems shall be bonded to the electrical service grounding electrode system at the point where the gas service enters the building. The bonding jumper shall be not smaller than 6 AWG copper wire or equivalent.
Can CSST gas line be buried?
Can it be buried? Yes, however it must be sleeved in a non-metallic conduit ½” larger than the pipe. 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).”.
How far can you run a flexible gas line?
Three- or six-foot long and accessible: The flexible connectors can’t go through walls, floors or ceilings, nor can they be concealed. The flexible connector length usually is limited to 3 feet except for gas ranges and clothes dryers. For these appliances, 6 feet generally is allowed.
Can CSST be used outside?
Installation Guide Pro-Flex CSST can supply gas throughout a home or commercial building. Route it through walls, floor or ceiling joists, or outside to a variety of appliances.
What is difference between grounding and bonding?
Bonding is the connection of non-current-carrying conductive elements like enclosures and structures. Grounding is the attachment of bonded systems to the earth. Both are necessary to safeguard people and property from electric hazards.
What does bonding a gas line mean?
To make it really simple, when metal that can carry electricity (but shouldn’t) gets connected together to eliminate potential, we call it bonding. If the metal accidentally carries electricity or even a static charge, proper bonding will allow the electricity to be carried back to its source in a safe manner.
Can you attach a ground wire to a gas line?
In summary, you cannot use a metal underground gas piping system as a grounding electrode. However, you must bond the piping system to the grounding electrode system for safety reasons.
How far should a ground rod be from a gas line?
The NEC requires all driven rods to be a minimum eight feet in the earth and for multiple connected rods a minimum spacing of six feet between rods.
Do you have to ground black iron pipe?
Systems that are made up of black iron (steel) pipe are bonded to prevent electrical shock in case the pipe comes into contact with an electrical circuit. But, the newer yellow corrugated stainless steel tubing needs to also be grounded to prevent it from exploding if struck by lightning.
Should gas lines be grounded?
CSST Gas Lines Must Be Grounded Since 2009, US building codes have required CSST to be bonded and grounded for safety, but that was not required during the first 18 years. The reason for this safety precaution is that a nearby lightning strike could cause the systems in your structure to become electrically energized.
Why is bonding of gas piping required?
The purpose of bonding interior metal piping to the building grounding system is to provide a safe electrical path to ground should the metal piping become electrically energized. This safety requirement is intended to protect the system user from shock and the gas piping system from damage.
Should gas pipe be bonded?
Bonding is required to prevent a possible electric shock hazard for persons that may be in contact with the gas piping and other grounded metallic building components. A stock hazard can result if these systems are energized at different levels of electrical potential.
How deep should CSST be buried?
It is manufactured presleeved. 1/2″@ 100feet is good for ~30-45kbtu depending on the gas pressure and allowable pressure drop. 6″ burial is way shallow.
Does CSST need to be in conduit?
It is recommended that the CSST be one continuous piece inside the conduit from end to end. CSST mechanical fittings are not allowed or permitted inside the conduit. Here is the gastite brand instructions. They allow penetrations through wood, but must be protected through masonry.
What type of pipe is used for underground gas lines?
Polyethylene gas piping systems are specifically engineered and certified for the underground environment.
