Oct 26, 2019 · Recognize that the pressure is high if the gauge reads higher than 3 bars or 45 psi. The pressure limits and ranges are different for each boiler depending on its size and type, but generally speaking, a pressure gauge should read between 1-2 bars or 15-30 psi. The pressure may be lower if it is warm out, or higher if it is cold out.Learn More

Jun 24, 2017 · Purpose of a pressuretrol. The pressuretrol starts and shutdown the boiler according to adjusted pressure it also controls its operating range. For example, an average operating range of a steam boiler may be 240 to 250 psi. When the steam pressure in the boiler drops 10 psi, the boiler will start up automatically.Learn More
Feb 25, 2020 · Baxi trainer Lance takes you through how to test the air pressure switch on the Baxi 105 range of boilers.Want to learn more? .baxitraining.co.ukFor more Learn More
The operator control should be set about 5–10 PSI above the actual steam pressure you want to maintain in the boiler. This allows the boiler to reach low fire and if steam pressure keeps rising, it will shut down the boiler. The boiler will restart when the pressure drops below the differential set on the operator.Learn More
When the fan operates effectively and air is proved at the air pressure switch, the micro switch moves to the proved air flow position NO terminal.. Some air pressure switches are marked with +ve or 1 and –ve or 2. (1 being positive and 2 being negative). Some air pressure switches are marked with L and H. (L being negative and H being positive).Learn More

A pressure switch in the natural gas line stops the burner if the gas pressure gets too high. If the natural gas pressure control valve fails, excessive gas can flow to the burner. If too much natural gas flows to a combustor, the burner could go out or the flame could be large enough to cause overheating.Learn More
4. When specifying low pressure steam boilers for steam demands below 293 kW (30 Boiler hp or 1,000,000 Btu/hr), the designer must ensure that adequate competition exists between at least three manufacturers.
