Description
The Laars Heating Systems E2305400 is an OEM 24-volt intermittent pilot (IP) ignition module engineered for reliable, safe burner ignition in Laars boilers and heating systems. Featuring a 5-minute trial-for-ignition (5mTFI) period and a single-try (1Try) lockout sequence, this module provides precise ignition control while protecting against unsafe operating conditions.
How It Works
On a call for heat, the module energizes the pilot valve and spark igniter simultaneously. If a flame is not established and proven within the 5-minute trial-for-ignition window, the module enters hard lockout after a single attempt, shutting down the ignition sequence to prevent unburned gas accumulation. Manual reset is required to restart the ignition cycle, ensuring technician awareness before re-energizing the system.
Key Features
- 24-volt operating voltage — compatible with standard low-voltage heating system controls
- Intermittent pilot (IP) ignition — pilot lights only on demand, improving energy efficiency
- 5-minute trial-for-ignition (5mTFI) — extended ignition window for reliable pilot establishment
- 1-try lockout — hard lockout after a single failed ignition attempt for maximum safety
- OEM Laars Heating Systems replacement part — ensures proper fit and function
- Designed for use in Laars boilers and hydronic heating equipment
Why Choose the Laars E2305400
Using a genuine OEM ignition module ensures compatibility with your Laars heating system’s control sequence and flame-sensing circuitry. The intermittent pilot design conserves energy by eliminating the standing pilot, while the single-try lockout provides an added layer of safety for residential and light commercial hydronic applications.
