Pressure regulators (as attached) allow high pressure liquefied gas to be reduced to lower, usable pressure. These regulators are usually installed between gas cylinders and gas stoves, gas burning water heaters or other household gas appliances.
The Bureau of Standards, Metrology and Inspection (BSMI) urges the public to use certified R280 pressure regulators (ones that come with a commodity inspection mark) to save energy, cut down gas cost and avoid carbon monoxide poisoning.
Since the inlet pressure of Taiwanese household gas appliances is set at 280 mmH2O, R280 regulators (with an outlet pressure of 280 mmH2O) should be used.
The use of non-R280 regulators (R500 has an outlet pressure of 500 mmH2O) will give rise to problems such as incomplete combustion, decrease in heat efficiency of the appliances, excessive gas rate and release of unnecessary gas and carbon monoxide into the atmosphere.
The BSMI urges the public to make sure that the regulators in use are R280 regulators. A replacement should be made immediately if the regulators are not R280 ones. The followings are important safety guidelines:
1.Make sure that the regulator comes with a commodity inspection mark like
2.Check the specification symbols engraved or shown on the product
2.1 R stands for outlet pressure, or pressure that comes out of the gas cylinder after regulation. R280 stands for an outlet pressure of 280 mmH2O.
2.2 Q stands for flow, or the amount of gas that flows out of the regulator every hour. Generally speaking, gas stoves require only flow rate Q1 (one kilograms per hour) and gas burning water heaters require flow rate Q2 (two kilograms per hour) or above. Large gas burning water heaters, however, may require flow rate Q3 (three kilograms per hour) or even Q4 (four kilograms per hour). Please match the specification of the regulator with the appliance.
3. Please contact qualified technicians and professionals for installation and
regular maintenance.
The BSMI urges the public to discard the misconception that a noisy flame equals to better combustion. Matching R280 pressure regulators can deliver sufficient amount of gas for combustion. The gas flow of gas burning water heaters is bigger than that of other gas appliances; the public should make sure adequate ventilation is in place to prevent carbon monoxide poisoning.
