In closed circuit systems, due to the lack of enough space to increase or decrease the volume of water, you must use an expansion source to control these changes.

Please note that to determine the capacity of your burner, you need the boiler output capacity, the combustion efficiency of the package, and the correction factor for the elevation above sea level at the installation site.. Keep in mind that “burner efficiency” or “boiler efficiency” on their own do not have any meaningful interpretation, and the manufacturer must specify the efficiency of the package based on the particular combustion system performance test..

Due to gas pipeline pressure, attention must be paid to the capacity and the declared number by the burner seller. In some capacities, gas pressure is low (less than 5 pounds per square inch), while in others, it requires pressure higher than this figure.

The recommended height limit for the steam boiler chimney is 6 meters, but it can be higher depending on factors such as capacity, diameter, friction rate of the chimney material, volume of combustion products, barometric pressure at the installation site, momentary pressure of combustion products exiting the nozzle, and fluid velocity.
