Q: What is an Ignition Transformer?
A: Ignition transformers are used to ignite a mixture of gas and air by delivering a high-energy spark to the end of an ignition electrode rod. The ignition transformer takes an input voltage & current and outputs a much higher voltage. For example, 120 volts can become thousands of volts — perhaps 10,000 (or more), so be very careful!
Ignition transformers are considered “direct spark” ignition. Before the popularization of direct spark technology, most burners were piloted. Unless they’re very big, burners today are primarily direct spark.
Combustion 911 offers several different ignition transformers.
Allanson’s 2260 and 2265 ignition transformers are compact, lightweight, and versatile. Though they only draw ½ an amp, these ignition transformers have full wave output and are designed for constant duty. The 2260 is for use with 120 Volts, while the 2265 is for use with 230 Volts.
TAR-10 ignition transformers are designed to provide a high-energy ignition spark for industrial burners. They can be used in systems which have UV sensors or a second electrode for flame detection. They can also be used in systems where a single electrode rod performs both the ignition and flame sensing duties (spark-and-sense).
