Honeywell ZT870 Flame Detector
Technical specs, application notes, replacement checks, and related model references.
Product Overview
The Honeywell ZT870 is a high-voltage ignition transformer specifically engineered to generate the powerful electrical spark required to ignite gas or light oil in industrial burners. It steps up standard line voltage to thousands of volts, ensuring a consistent and robust ignition arc even under challenging high-velocity airflow conditions within the combustion head. A fundamental component for commercial boilers, process heaters, and forced-draft furnaces, the ZT870 guarantees reliable and immediate burner start-ups during every firing sequence. Built with heavy-duty insulation and durable casings, it provides long-lasting performance and exceptional resistance to thermal and electrical stress.
