The second stage regulator is a regulator reducing the pressure coming from a first stage regulator directly to the inlet pressure of the user appliance or to a medium pressure value in case of installations with pressure governors.

Therefore 988 LP Type regulators are designed for Type A installations. They have to be used outdoors in correct mounting position with vent-hole turned downwards.

In the standard version these regulators are delivered with vent-hole in line with the inlet fitting.

But there are three other configurations of the inlet and outlet fittings for the 998LP model; Back Mount 998 LP-03 and 998 LP-04, Angle Body 998 LP-05, Inline inlet and outlet Flange 998 LP-09 and 998 LP-10.
