Product Details

The Fireye YP148 is a plug‑in interchangeable programmer module exclusively built for the Fireye BurnerLogix YB and ZB series burner management chassis. This plug‑in programmer module defines the full burner safety sequence, featuring a 4‑second flame failure response time and built‑in valve proving system to verify gas valve integrity before ignition starts. As a reliable valve proving burner sequencer, it supports modulating burners, pilot and main fuel valve control, and field configurable timings including pre‑purge, pilot trial for ignition and safety interlock behaviour. This Fireye YP148 sequencer is stocked as genuine replacement spare part, widely used for gas‑fired boilers, packaged process heaters and commercial industrial burner systems that require valve proving compliance.

Supported Functions

This plug‑in programmer module controls the complete automatic firing sequence including pre‑purge, pilot ignition trial, main flame light‑off and steady‑state run supervision. The valve proving burner sequencer performs valve leak testing prior to ignition to confirm fuel tightness. If flame loss is detected, it triggers lockout and fuel shutoff within 4 seconds. This Fireye YP148 sequencer allows adjustment of timing parameters via local display and works with UV, self‑check UV or IR flame amplifiers depending on the paired chassis.

Core Functions

The built‑in valve proving function reduces risk from leaking fuel valves and helps meet modern combustion safety codes. The plug‑in programmer module governs recycle / non‑recycle logic and coordinates blower, ignition, pilot and main valve outputs following certified safety timing. Its hot‑swap plug‑in design enables drop‑in substitution for a faulty YP148 without rewiring the entire chassis, provided the existing BurnerLogix hardware matches.
