Product Details
The Fireye YP138 is a plug‑in interchangeable programmer module for Fireye BurnerLogix YB and ZB burner management chassis, featuring non‑recycle operation, 4‑second flame failure response time, damper proving and indefinite pilot hold function. This plug‑in programmer module supports revert‑to‑pilot from auto modulation mode, with all core timings configurable through the local display keypad. As a reliable indefinite pilot hold sequencer, it is designed for modulating gas and dual‑fuel burners that require stable pilot flame retention during load swings, and it works with UV self‑check or IR flame amplifiers depending on the matched chassis. This Fireye YP138 burner programmer is stocked as genuine replacement spare part, widely used on industrial boilers, packaged heaters and process combustion systems demanding pilot‑hold capability.

Product type: Original Fireye burner sequencer spare programmer module
Supported Functions
This plug‑in programmer module executes the full automatic firing sequence including pre‑purge, pilot trial for ignition, main flame light‑off and run‑time flame supervision. The indefinite pilot hold sequencer maintains pilot flame continuously when the dedicated terminal is energized and can drop back to pilot operation automatically under special load conditions. If flame loss occurs, it triggers safety lockout and fuel shutoff within 4 seconds. This Fireye YP138 burner programmer allows adjustment of purge, ignition and safety timings on‑site and supports modulation control for stable firing rate regulation.
Core Functions
The built‑in pilot hold logic keeps the pilot lit instead of cutting it off after main flame establishment, ideal for processes with frequent load fluctuation. The plug‑in programmer module governs blower, igniter, pilot and main fuel valve outputs following certified safety timing and non‑recycle lockout rules. Its hot‑swap plug‑in design enables drop‑in substitution for a faulty YP138 without full chassis rewiring, provided the existing BurnerLogix host hardware is compatible.
