Kromschroder Ignition transformer TGI8-20/33WE 84391280

The Kromschroder TGI8-20/33WE is an ignition transformer with SKU 84391280, designed for burner systems. It steps up the mains voltage to generate a spark across an ignition electrode gap, operating only during the ignition phase under burner control. The transformer is built to comply with the Machinery Directive 2006/42/EC and CSA C22.2 No. 13-1962 standards. Its ignition cable is silicone-insulated to withstand high voltage and heat.

When selecting a replacement ignition transformer of this type, key parameters include primary voltage (e. g., 230 V, 110 V, or 24 V), secondary output sufficient for ionization, duty cycle (intermittent vs. continuous), mounting dimensions, and high-voltage cable connector pattern. The mounting arrangement and connector type must match the existing installation. Always inspect the ignition cable for insulation breakdown and replace if hardened, cracked, or chafed. Verify electrode gap and position per burner specifications to avoid spark failure or arcing.

Typical failures include insulation breakdown of the ignition cable, leading to spark leakage to earth and apparent transformer malfunction. A hardened, cracked, or chafed cable can cause this. Additionally, an excessively wide electrode gap may prevent spark striking, while a too-narrow gap can cause arcing that stresses the transformer. Check cable condition and electrode gap when ignition issues occur.
