Slant Fin 411-929-000 Gas Valve

The Slant Fin 411-929-000 Gas Valve is a critical component for technicians servicing gas-fired boilers and hydronic heating systems. This 24V intermittent pilot gas valve is engineered specifically for natural gas applications, featuring a standard 3/4" x 3/4" NPT inlet and outlet configuration for seamless integration into existing manifolds. As an industry-standard step-opening gas valve, it provides a controlled initial ignition pressure of 0.9" WC, eventually reaching a full-rate 3.5" WC manifold pressure. This modulation ensures stable combustion and prevents hard ignitions in Slant Fin boiler modules and residential units. With a capacity rating of up to 300,000 BTU/hr, it supports a wide range of appliance sizes. The dual-valve design incorporates redundant safety shutoffs, meeting rigorous codes for fuel control. All necessary technical adjustments, including the pressure regulator and pilot gas outlet, are accessible from the top of the control, facilitating efficient field tuning and testing during maintenance calls.

• Precise Pressure Regulation: Factory-set at 3.5" WC for natural gas with a step-opening feature to ensure quiet and reliable burner ignition.
• Universal Compatibility: Standard 3/4" gas valve threading matches common piping requirements for Slant Fin and other high-capacity boilers.
• High BTU Capacity: Rated for up to 300,000 BTU/hr (at 1" pressure drop), making it suitable for both modular and single-unit heating systems.
• Direct Tech Access: Top-mounted 1/4" quick-connect terminals and pilot adjustments allow for fast wiring and troubleshooting.
• Standard 24V Operation: Compatible with common HVAC intermittent pilot controls and 24VAC transformer circuits.

Is the Slant Fin 411-929-000 compatible with LP gas?
This valve is factory-configured for natural gas. For propane applications, a specific manufacturer-approved conversion kit must be used to adjust the spring and regulator settings to the required manifold pressure.

What ignition systems work with this valve?
This is an intermittent pilot gas valve (IP) designed for use with electronic ignition modules. It is not intended for standing pilot systems where a thermocouple is the primary safety device.

Can this valve be mounted in any orientation?
Field standards permit mounting from 0 to 90 degrees in any direction from the upright position of the control knob, including vertical applications, though horizontal mounting is most common for manifold stability.
