R600 and HSRL Series LP-Gas Regulators The inlet and outlet pressure plug may be removed using a 7/16 in. / 11 mm hexagon wrench. The pressure tap is restricted, so the plug can be removed with pressure on the outlet of the regulator. Install a pressure gauge to determine the regulator’s inlet pressure and outlet setting during adjustment, (actual pressure at the second stage regulator may be less due to line loss). After setting, add thread sealant to the 1/8 in. NPT pipe plugs. Reinstall the pipe plugs by threading into the gauge ports finger-tight and then wrench tighten 1-1/2 to 3 turns...
