Side

( 14"wc) - Typical 2 psig and 5 psig SystemsStep 1 Select the type of Gas (cell "M10")

Step 2 Enter Supply Pressure (cell "M11") - Natural Gas Meter or Propane (LPG) Regulator Outlet Pressure. Ex.: For 2 psig systems, 2 psig is approx. 56 "wc.

Step 3 Enter Minimum Inlet Pressure to the LPR (Line Pressure Regulator) (cell "M12"). This is the Supply Pressure minus the allowable pressure drop across the

elevated pressure side piping.

Step 4 Enter the LPR outlet pressure (cell "M13").

Step 5 Enter Minimum Allowable Delivery Pressure at the Appliance (Inlet pressure from equipment data plate) - (cell "M14")

Step 6 Pipe runs (Column A) on SOPL worksheet shall correspond to Pipe runs from your TracPipe-Counterstrike Windows Specifier drawing (see example below) or assign pipe runs

to a gas piping drawing corresponding to labels in Column A below.

Step 7 Select supply pressure (Source) for each run on the Elevated Pressure Side (>14"wc GREEN Column) from COLUMN Bdropdown. Note: Select "1" for meter or LPG Regulator Outlet (Supply 1).

Lettered selections (A, B, C) refer to pressure at end of the run. For example; if Pipe Run "D" is connected to the end of Pipe Run "C",

then select "C" from the dropdown.

Step 8 Select supply pressure (Source) for each run on theLOW Pressure Side (
