To Use Chart: Having determined the required flow at point of use, locate this flow in the left hand column. If this falls between two figures, use the larger of the two. Determine total length of piping required from source to point of use. Read across chart from left (required flow) to right to find the total length which is equal to or exceeds the distance from source to use. From this point read up to find the correct size of pipe required. Reference Rego LP-Gas Serviceman’s Manual.
