NOT to over tighten any of the fittings. When I reconnect gas lines and open valves at tanks. Watch out: in addition to a gas supply shut off valve at the LP or propane gas cylinder or tank (or at the building gas main where piped-in natural gas is supplied), additional gas supply shutoff valves are required in the gas piping system at each gas-fired heating device or appliance. Slowly turn the cylinder valve on in a counter clockwise direction until you hear the gas begin to flow into the regulator. At individual natural gas appliances the gas pressure will be regulated to about 0.25 psi, Dwyer Instruments, 1213 Series gas pressure gauge, retrieved 2018/01/18, original source: http://www.dwyer-inst.com/Product/Pressure/Manometers/Stationary/Series1213, National Fuel Gas Code, ANSI Z223.1-yyyy - American Gas Association / National Fire Protection Association, LP-Gas Serviceman's Handbook,Fisher-Rosemount, Fisher Controls. Will help to become competent with the equip. Have checked both regulators at tanks and have 11" water column on both. A 20 Litre Bottle filled to 200 bar (approx 3000 psi), would contain 4000 Litres (20 x 200). Normally you close the LP tank gas valve by turning it "clockwise" or as my daughter Mara says, "rightie-tightie, leftie-loosie" to help remember this important information. You should refer to your equipment for the amount of gas required to operate it. Smell and sound coming from screen on regulator. 268 0 obj <> endobj Take the pressure regulator and place the connecting piece on the clip on your pressure regulator. The same problem can occur with gas water heaters. On 2020-02-18 - by (mod) - does a gas regulator problem cause "high" indoor carbon monoxide gas levels?

Slowly turn the cylinder valve on in a counter clockwise direction until you hear the gas begin to flow into the regulator. This is quite normal and will go back down once gas starts to flow again.

Gas Equipment threads do not seal at the thread and using thread sealer will most likely cause leaks and can be dangerous. Continue to turn the Control Knob until the desired Flow Rate/Pressure is reached. trailer The yellow cover on top of the valve is the connector for filling the LP gas tank. A 20 Litre Bottle filled to 200 bar (approx 3000 psi), would contain 4000 Litres (20 x 200). 0000224037 00000 n In a better installation the vent on this regulator would have been aimed downwards.

Lack of Regulator Gauge accuracy is possible, but unlikely, far more likely is the cylinder has been under filled, or has a small valve leak.
Close the torch Control Valve or deactivate the Mig/Tig Welder. Great info for us rookies. Remember to unscrew the Control Knob bar to loose and floppy before fitting to a pressurised gas cylinder. Slowly open the Cylinder Valve to turn the Gas ON. Apologies for the delay.

0000008526 00000 n Hi Barry Please let me know what you thought of this article by leaving a comment. emergency line and/or your fire department. Illustration: a typical gas pressure gauge reading in inches of water or Inch H2O as sold on eBay.

In photo at above the red LP gas regulator can be seen installed in a tipped position in upper center of the photo. I regret I don’t know the answer to the Delivery Pressure question as one usually uses Pressure OR Flow rate and you’re clearly using Flow Rate. How to Inspect & Test LP Gas Valves Regulators, or Gas Controls Mig and Tig Welders will normally specify a Flow Rate in Litres Per Minute (LPM). The pressure starts out fine at 11/12 inH20 but over time goes up and up. Open your Gas Torch Control Valve or activate Mig/Tig Welder, so gas flows, note how the Delivery Gauge and Cylinder Contents Gauge Needles drop to Zero. be possible to correct this at the regulator, but don't try boosting pressure at a gas regulator unless the pressure has always been too low. A mistake can lead to a fire, explosion, injury, or death.

Otherwise when the underlying cause for low gas pressure is corrected elsewhere, the flame will be too big and pressure too high at the burner - an unsafe condition. Well I hope you found that informative and useful. On 2019-08-06 - by (mod) - What is the typical pressure in a 2 stage regulator system, Paul all of those pressures are detailed atGAS PRESSURES LP vs NATURAL GAS. With hand over the regulator, place thumb against central spindle/shaft of control lever and press firmly towards the body of the regulator. 200 gallon and 100 gallon connected together. Thanks for the comment Jon, glad you found the article useful. 0000162050 00000 n Hi, 0000006335 00000 n Open your Gas Torch Control Valve ½  turn (note no gas will come out at this time). The purpose of the regulator is to control the flow of gas and lower the pressure from the LP Gas tank to the appliance(s) in the gas system. If your using 3 x 7 LPM, that’s 21 LPM, then it’s 4000/21 = 190 minutes (just over 3 hours). Turn the Cylinder Valve OFF. 0000002267 00000 n 0000003521 00000 n 0000276849 00000 n Follow these simple steps (if using two gases, do the following for each gas separately): Open your Gas Torch Control Valve or activate Mig/Tig Welder, so gas flows, note how the Delivery Gauge and Cylinder Contents Gauge Needles drop to Zero. Carry out procedure in a well ventilated area with no combustion sources if the gas is flammable. Watch Out: Immediate LP or natural gas safety hazards: If you smell gas you should leave the building immediately and should do so without doing anything that could create a spark such as operating a light switch or telephone. New furnace.New tanks.New regulators. %PDF-1.4 %���� Keep up the good work Graham and co. 0000009525 00000 n Try the search box just below, or if you prefer, post a question or comment in the Comments box below and we will respond promptly. Closing down your equipment correctly is as important to its long term reliability and accuracy as the set up.

Ensure the Gas Regulator Control Knob (big Black Knob with Blue Cap in the picture), is unscrewed to the point where it is loose and floppy. Thanks for the comment Jon, glad you found the article useful. If your using 3 x 7 LPM, that’s 21 LPM, then it’s 4000/21 = 190 minutes (just over 3 hours). Most 2-psi output gas regulators include a test port intended specifically for this purpose. Gas pressure too low: if the gas regulator is not properly adjusted or if there are other problems in the gas piping or supply Hi, Unscrew the Gas Regulator Control Knob until it goes loose and floppy. Slowly turn the Gas Regulator Control Knob clockwise. When you start to feel resistance the gas should start to flow and the Delivery Gauge Needle will start to move around the scale. W.C. 0000056350 00000 n

Attach the pressure gauge to the outlet tap of the regulator. The following list explains delivery Flow Rate/Pressure setting (if using two gases, do one gas at a time). 0000010563 00000 n

Wait about 10 seconds then proceed to fully open the cylinder valve.

Note the Contents Gauge Needle pops up to show the pressure in the cylinder. Any drain openings should be facing downwards.

The plumber attaches a pressure gauge or a manometer to the regulator output side where she can see what pressure the regulator is delivering. NOTE:For greater safety never stand in front of a regulator when opening the cylinder valve. Watch out: Document the regulator measurements made in both of these tests, including the date, location, test operator, test pressure results, and results of leak tests performed. 0000109636 00000 n

If the supply regulator cannot maintain the required flowing gas pressure the problem may be any of the following: An important additional gas pressure regulator safety check is for the "lock-up" gas pressure in your system. To read Lock-up (or static) gas pressure. BobThanks for asking an important life-safety question: does a gas regulator problem cause "high" indoor carbon monoxide gas levels? I would go back to the cylinder supplier and take it up with them.
