Laars Heating Systems RV2017903 Gas Valve
Working on a Laars NeoTherm NT210 requires precise fuel-to-air regulation to maintain the high-efficiency performance these condensing boilers are known for. The Laars Heating Systems RV2017903 Gas Valve/Venturi assembly is the OEM solution specifically engineered for the NTH210 and NTH210NXN3 models. This integrated component controls the natural gas flow and manages the pressure differential necessary for a stoichiometric air-fuel mixture. As a critical part of the gas train assembly, it ensures stable combustion across the unit's full modulation range, preventing issues with flame rectification or nuisance lockouts. When field-replacing a Laars RV2017903, technicians must verify the 13" W.C. maximum inlet pressure and perform a combustion analysis to calibrate Hi-Fire and Low-Fire CO2 levels. This replacement gas valve is built for durability in residential and commercial hydronic systems, ensuring the secondary heat exchanger remains free of soot caused by improper combustion gas mixing.
Key Benefits:- OEM Compatibility: Exact fit for Laars NeoTherm 210 series, eliminating the need for manifold modifications.
- Integrated Venturi: Factory-matched Gas Valve/Venturi NT 210 assembly ensures a precise pressure drop for optimal 10:1 modulation.
- Efficient Combustion: Designed to maintain strict CO2 and O2 levels for clean operation and reduced emissions.
- System Reliability: Replaces worn internal diaphragms that cause "failed to ignite" or "flame lost" boiler error codes.
- Does this valve support Propane (LP) conversion? This assembly is configured for natural gas; always verify the orifice and spring kit requirements if converting a NeoTherm NTH unit.
- Is a combustion analyzer required for installation? Yes, per Laars technical specifications, any gas valve replacement requires a digital combustion analysis to set the high and low modulation firing rates.
- Does it include the venturi gaskets? The RV2017903 typically includes the assembly, but technicians should always inspect the cork gasket and gas valve O-ring for a gas-tight seal.
