Imperial 451-CB Replacement Gauge Low Side

For service technicians requiring a reliable intermittent pilot ignition control, the Lennox 30W33 Ignition Module Kit serves as the direct OEM replacement for aging Honeywell S8670K3000 units. This kit is engineered for 24V gas-fired systems, providing a 30-second pre-purge and a 90-second trial for ignition to ensure safe and efficient burner cycles. As a comprehensive HVAC furnace repair kit, it includes the necessary flame sensor (49L76), mounting bracket, and wiring harness to facilitate a seamless field installation. The module features continuous retry logic and integrated LED diagnostic codes to streamline troubleshooting of common flame-sensing or internal error issues. Designed specifically for compatibility with Lennox G20, G23, and G26 series furnaces, this genuine Lennox part restores precise 2nd-rod sensing and pilot gas valve control (PV/MV outputs) without the need for additional modifications.

Key Benefits:

• OEM Compatibility: Specifically designed to replace Lennox part numbers 18G91, 63K24, and 80N92.
• Complete Installation Kit: Includes the Honeywell S8670K module, spark ignitor, and flame sensor for a full ignition system overhaul.
• Advanced Diagnostics: Built-in LED flash codes allow technicians to quickly identify low input voltage or flame out of sequence faults.
• Robust Performance: Rated for 1A PV / 2A MV maximum loads at 60Hz, ensuring reliable operation of the pilot and main gas valves.
• Enhanced Safety: Features a regulated 30s pre-purge period to clear the combustion chamber before each ignition attempt.

Common Questions:

What does it mean if the 30W33 module shows 2 flashes?
A 2-flash code typically indicates the system is in a 'Retry' state, meaning the module failed to sense a flame during the 90-second trial and is attempting to re-establish ignition.

Is this kit compatible with older Lennox G12 models?
Yes, this ignition control kit is frequently used as a field replacement for the Lennox G12 series, provided the electrical specifications and bracket mounting meet the original furnace requirements.

Does the kit include a new flame sensor?
The Lennox 30W33 kit includes the 49L76 flame sensor and the necessary insulated 1/4" quick connects for a secure electrical interface.
