Question

Name three types of furnace ignition systems.

a) Standing pilot, hot surface ignition, intermittent pilot
b) Spark ignition, direct ignition, induced draft ignition
c) Piezo ignition, electric ignition, manual ignition
d) Electronic ignition, battery ignition, constant pilot

Answer 1

Three types of furnace ignition systems are standing pilot, hot surface ignition, and intermittent pilot.

Step-by-step explanation:

Three types of furnace ignition systems include:

1. Standing pilot: This type of ignition system uses a continuously burning pilot flame to ignite the main burner. It is commonly found in older furnaces.
2. Hot surface ignition: In this system, an electric resistance element becomes hot when an electrical current passes through it. The hot surface then ignites the gas and starts the burner.
3. Intermittent pilot: This ignition system uses a spark to ignite the pilot, and once the pilot is established, it ignites the main burner.
