Laars Heating Systems V0079400 Gas Valve
The Laars V0079400 Gas Valve is a critical replacement component engineered specifically for Laars heating systems requiring a 24V gas control valve. This valve is calibrated for a 3" WC manifold pressure (Natural Gas) and features a standard 1/2" NPT inlet and outlet for seamless integration into existing manifolds. Designed for high-reliability ignition sequences, the V0079400 ensures precise fuel metering and consistent pilot or hot surface ignition performance. It is a direct OEM match for specific Laars Pennant pool heaters and commercial boiler models. When replacing this unit, technicians should verify the Honeywell or White-Rodgers cross-reference to ensure electrical load compatibility with the 24-volt transformer and controller. This robust HVAC gas valve is built to handle the cycling demands of high-efficiency hydronic systems while maintaining narrow pressure tolerances for optimal combustion efficiency and boiler troubleshooting accuracy.
Key Technical Benefits
- Precise Pressure Regulation: Fixed 3.0" WC setting ensures stable burner manifold pressure for efficient combustion.
- OEM Compatibility: Specifically engineered for Laars Heating Systems, facilitating a direct "drop-in" replacement without piping modifications.
- Standardized Connections: Utilizes 1/2" NPT threading for universal fitment in standard HVACR gas lines.
- Reliable 24V Operation: Designed for standard low-voltage control circuits typical in commercial and residential boiler applications.
- Integrated Safety: Features high-integrity internal shut-off mechanisms to maintain system safety during standby or lockout modes.
Common Technical Questions
Can this gas valve be converted to Liquid Propane (LP)?
The V0079400 is factory-set for Natural Gas at 3" WC. For LP applications, a manufacturer-approved conversion kit must be installed to adjust the orifice and spring tension for the higher pressure requirements of propane systems.
What are the symptoms of a failing Laars gas valve?
Common failure points include a cracked internal diaphragm, sticking solenoid coils, or a failure to open despite receiving 24V from the control board. If you measure 24V at the terminals but have no manifold pressure, the valve likely requires replacement.
Is this a slow-opening or fast-opening valve?
This specific model is typically a fast-opening valve, ensuring immediate gas flow to the burner assembly upon ignition signal to prevent delayed ignition or "booming" in the heat exchanger.
