Portable LP cylinder attached to a first stage regulator via a Model #TPF (using  M.POL connectors) with the Presto-Tap patented Ambient Temperature 300 psig gauge (Model #6800) attached.

First Stage Regulator (in this instance a Fisher R522H-HGJ) with a Presto-Tap LDS 2000/RV (Regulator Valve) in the tank pressure inlet pressure tap (with a Model #6800 attached) and a LDS 2000/RV-L (Regulator Valve Low- Pressure) in the outlet 10# pressure tap location with a 15# psi gauge attached via a Presto-Tap RV/QA (Regulator Valve Quick Adapter) and attached to the Second Stage Regulator with ½” iron pipe.

Illustrating a location outside the structure, a Presto-Tap “Tamper-Resistant” LPV (Low-Pressure Valve) installed in the piping upstream the second stage regulator is shown with a 30# psi gauge attached using a Presto-Tap RV/QA.

Second Stage Regulator (in this instance a Fisher R522-BCF) with a Presto-Tap LDS 2000/RV-L installed in the inlet pressure tap and a LDS 2000/RV installed in the outlet pressure tap.  Attached to the 2000/RV, using a Presto-Tap RV/QA with a hose barb installed, is an “Inches of Water Column” gauge.

Illustrating a location inside the structure, a Presto-Tap “Tamper-Resistant” LPV (Low-Pressure Valve) installed in the piping where an appliance is to be connected is shown with a water manometer attached using a Presto-Tap RV/QA with a hose barb installed.

After installing the appropriate M.Flare x ½” M.NPT fitting (not supplied by Presto-Tap) in the Presto-Tap LPV, an appliance can be connected.  In this instance, a Rinnai RETS-1NEA is being used.

NOTE: The products are shown with POL and hose barb connectors for illustration purposes only (these connectors must be ordered separately).

The LDS 2000/RV, the LDS TPF, and the LDS LPV are UL Listed.  The LDS 2000/RV-L is not UL Listed.
