Description

The Kromschroder Thermo pilot burner ZT40G-100A (SKU 84221014) is a thermoelectric pilot burner designed for gas-fired systems. It has a tube diameter of 40 mm and is compatible with the Kromschroder S11T valve. This burner operates without external power supply and provides a continuous flame signal for safety circuits. It is manufactured in Germany.

Further details

Common failure modes	blocked gas orifice, distorted flame tube, damaged thermocouple/electrode assembly
Comparison before order	compare physical length, thread type, electrode configuration with existing unit
Ignition sequence	spark from ignition transformer lights pilot flame; flame-sensing device confirms pilot is burning
Replacement factors	burner series, gas flow rate, mounting flange dimensions, flame position
Safety lockout	control box locks out if pilot flame lost

Choosing and fitting

When selecting a pilot burner of this type, verify the tube diameter, length, and mounting configuration against the existing unit. Ensure compatibility with the thermoelectric safety valve (e.g., S11T) and check the gas orifice size for the specific gas type. Compare the flame position relative to the main burner head to ensure proper ignition.

Signs of failure

Common failures include blocked gas orifices, distorted flame tubes, or damaged thermocouples, leading to loss of pilot flame or weak signal. Symptoms may include failure to ignite the main burner, intermittent flame loss, or safety lockout. Check for debris, physical damage, and continuity of the thermocouple circuit.
