Fida Ignition transformer 26/35 IT ENTB32

The Fida Ignition transformer 26/35 IT ENTB32 is a component designed to step up mains voltage to a level sufficient for creating a spark at the ignition electrode gap in gas burners and boilers. It operates only during the ignition phase, under command from the burner control, and is de-energized once flame is proved. This transformer is compact and suitable for installation in confined spaces, and it is compatible with boiler models requiring characteristics of 26/35 IT. It is manufactured by Fida and falls under the category of ignition transformers.

When selecting a replacement ignition transformer of this type, verify that the primary voltage, secondary output, and mechanical mounting match the original. Check the terminal layout and any cable connector pattern to ensure fit with the burner's wiring. Also confirm the duty cycle rating suits the application, as continuous or extended sparking can shorten transformer life. Mounting types may include flange or bracket, and the ignition cable must be silicone-insulated to withstand high voltage and heat.

Typical failure modes for ignition transformers of this kind include internal short circuits or open windings, leading to no spark at the electrodes. The equipment may fail to ignite, causing the burner to lock out after repeated attempts. Check the ignition cable for hardening or cracks, as a damaged cable can leak the spark to earth and mimic a faulty transformer. Also inspect the electrode gap and condition, as incorrect gap or fouled electrodes can prevent ignition.
