Understanding Ignition Lock Assemblies
Hot Surface Ignitor (HSI)
AHot Surface Ignitoris an electronic ignition device that heats up to extremely high temperatures (typically 1800-2500°F) to ignite the gas in your furnace or heating system. Made from silicon carbide or silicon nitride, it glows bright orange when activated.
What it does:
- Receives electrical current and heats up rapidly
- Ignites the gas when it reaches proper temperature
- Provides reliable, consistent ignition
- Eliminates the need for a standing pilot light
Direct Spark Ignitor
ADirect Spark Ignitoris an electronic device that creates a high-voltage electrical spark to ignite the gas. It's similar to a spark plug in your car but designed specifically for heating appliances.
What it does:
- Creates a controlled electrical spark
- Ignites gas directly without pre-heating
- Provides instant ignition
- Operates with high reliability in various conditions
Intermittent Pilot Ignitor
AnIntermittent Pilot Ignitoris a hybrid system that uses a spark to light a small pilot flame, which then ignites the main burner. This system only operates the pilot when heat is called for.
What it does:
- Creates a spark to light the pilot flame
- Monitors the pilot flame through a flame sensor
- Conserves gas by only operating when needed
- Provides reliable ignition in cold conditions
Standing Pilot Ignitor
AStanding Pilot Ignitoris the traditional ignition system that maintains a constant small flame (pilot light) to ignite the main burner when needed. While less common in modern appliances, they're still found in older systems.
What it does:
- Maintains a continuous pilot flame
- Ignites main burner when heat is called for
- Operates without electricity
- Provides simple, straightforward operation
Note: The type of ignitor your system needs depends on your specific appliance model and manufacturer specifications. Always consult with a qualified technician for proper selection and installation.
