What to check before ordering

  • Check both the pressure arriving from the first stage and the required final outlet setting.
  • Use the full appliance demand and the manufacturer’s stated rating conditions when comparing capacities.
  • Have your installer check vent clearance, protection from weather, operating pressure and system tightness.

Service reminder: A matching pipe connection is only one part of the selection. Keep the vent clear, follow the specified vent orientation and piping requirements, and replace any submerged regulator.

Have gas-system installation and service completed by qualified personnel. Use the current instructions for the exact model and the requirements that apply at the installation location.

Overview

Engineered Controls Dielectric Second Stage Gas RegulatorMFG# LV4403B46D | DLP# 1LP3277This premium dielectric second stage regulator by Engineered Controls is specifically designed to reduce first stage gas pressure (up to 10 PSIG) down to burner-ready levels, typically 11″ W.C. It’s ideal for residential and medium commercial propane and LP gas systems using multiple cylinder installations.What sets this model apart is its integrated dielectric union, eliminating the need for a separate dielectric fitting. This feature protects against stray electrical current transfer from metallic piping systems—crucial for safety when piping enters buildings.The inlet features a 1/2″ F. NPT union with brass and plated steel construction, while the 3/4″ F. NPT outlet ensures compatibility with standard LP piping systems. The bonnet includes a clear model ID marking for easy reference and an over-inlet vent design to minimize vent freeze.
