1 Gas fitting line Sizing

2 Natural / LP Gas fitting line Sizing Information Needed.
Type of Gas = ? Natural / LPG Type of Gas Heat Value = ? Heating Value Mj/m³ & Relative Density (RD) Available Pressure at start of consumer piping The Gas Authority should be consulted to determine the maximum pressure drop Allowed in area. To minimise noise the maximum pressure drop should not exceed 10% of the operating pressure. Type A appliances minimum - inlet pressure Clause No Table 4.1 Natural Gas- minimum - inlet pressure kPa / Min. Inlet Pressure LPG 2.75 kPa Pressure drop = ? 0.075kPa Natural gas / 0.25 LPG

3 Natural / LP Gas fitting line Sizing Information Needed.
Type of Pipe = ? Copper / Steel /Plastic Mj/h each Appliance ? Appliance Data Plate Manufactures Information sheet Main Run = ? Measure plan
