Section 3, supplying outlets A, B, C, and D, or 230 cubic feet per hour, requires one-inch pipe.
Do not use an open flame to test for leaks. Continue this process until you have no leaks. Bubbles show a leak and you should repair it appropriately. Check for leaks by filling a spray bottle with soapy water and spraying the solution on the pipe, where it meets the fittings. If there is a drop in pressure, check for leaks. Where the gauge does not indicate the minimum pressure required for the test, or any reduction of test pressures as indicated by pressure gauges during inspection shall be deemed to indicate the presence of a leak. The piping system shall be under test (pressurized) and the test gauge visible at the time of inspection. A 10 psi test could be performed using a 50 pound gauge, but not a 100 pound gauge. For instance, a 3 psi test will require a maximum 15 pound gauge. Mechanical gauges used to measure test pressures shall have a range such that the highest end of the scale is not greater than five times the test pressure. The piping system shall withstand the test pressure specified without showing any evidence of leakage or other defects. The test duration shall not be less than 10 minutes. The test pressure shall be at least 1 ½ times the working pressure, but no less than 3 pounds per square inch (psi). The inspector does not perform the test or provide any of the equipment necessary for the test, including test gauges.Īn air pressure test is required. Testing the system is your responsibility. All gas piping installations require a permit and inspection. Within the City of Seattle only, any person who installs gas piping on property not under their ownership must possess a Seattle Gas Piping Mechanic License. Each place where you will have a gas appliance must have a gas shutoff valve. Special instructionsĭo not use ground joint unions except directly at the meter or after the shutoff valve at the appliance.

If you are cutting iron pipe, you must ream the cut of your pipe so you maintain the full inside diameter of the pipe.

CSST requires certification from the manufacturer for anyone who is going to purchase and install the material. To get BTU from cubic feet, multiply cubic x feet 1100 (45.45 cubic feet x 1100 = 50,000 BTU.) Approved gas piping fitting materialsīlack iron and corrugated stainless steel (CSST) are commonly used approved materials. See the example on the back of this insert to help further illustrate this. To convert from BTUs to cubic feet per hour divide BTU by 1100 (example: 50,000 BTU by 1100 = 45.45 cubic feet of gas per hour). Look at the chart on the back of this insert to assist you in determining the proper pipe size for your job. The chart below gives some examples of typical BTU demands. Each appliance has a minimum input demand in BTUs per hour. Proper sizing of the pipe is important so that each gas appliance receives enough gas to perform properly.
