Laars Heating Systems RV2017904 Gas Valve/Venturi Kit

Laars Heating Systems RV2017904 Gas Valve/Venturi Kit

The Laars RV2017904 Gas Valve/Venturi Kit is a critical replacement component for high-efficiency Laars NeoTherm condensing boilers and volume water heaters. This assembly integrates a precision negative regulation gas valve with a high-performance venturi to ensure the exact air-fuel ratio required for modulating combustion. Engineered to maintain a 5:1 turndown ratio, the RV2017904 facilitates stable ignition and consistent thermal output across the entire firing range. It is designed to handle inlet gas pressures between 4" and 13" W.C., providing reliable gas flow control for NTH 500 and NTV 500 models. This OEM Laars replacement part features a durable 24 VAC solenoid and is essential for resolving Error Code 110 or ignition failure issues. The kit includes the necessary gaskets and O-rings to ensure a gas-tight seal at the blower and manifold connections, maintaining the safety and 95% AFUE efficiency ratings of the NeoTherm series.

Key Benefits:
  • Ensures precise negative pressure regulation for optimal combustion efficiency in NeoTherm NTH/NTV 500 units.
  • Facilitates accurate air-gas mixing, maintaining the system's 5:1 modulation capabilities and low NOx emissions.
  • Corrects gas valve solenoid failures and internal blockage issues that lead to persistent soft lockout conditions.
  • Genuine Laars Heating Systems component ensures exact fitment and compatibility with existing 24V wiring harnesses and control boards.
Common Questions:
  • How do I diagnose a failing gas valve on a NeoTherm boiler? Technicians should check for Error Code 110 (ignition failure) or Error Code 67. Use a digital manometer to verify the negative regulation settings and ensure the inlet pressure remains within the 4" to 13" W.C. range during the ignition trial.
  • Is this kit compatible with both Natural Gas and Propane units? This specific kit is often configured for Natural Gas; however, field conversion may require specific orifices or adjustments. Always verify the manifold pressure against the rating plate specifications during installation.
  • Does the kit include all necessary seals for the blower transition? Yes, the RV2017904 typically includes the flange gaskets and O-rings required to reseal the venturi-to-blower and gas-train connections.
