Hot surface ignition is a common method used to ignite gas burners. It involves the use of a hot surface to light the gas, eliminating the need for a pilot light. The 1018 series hot surface ignition wiring diagram is an important document for HVAC technicians who need to troubleshoot or repair a hot surface ignition system.
What is a 1018 Series Hot Surface Ignition System?
A 1018 series hot surface ignition system is a type of electronic ignition system used in gas furnaces. It uses a silicon nitride hot surface ignitor to ignite the burner. The ignitor is heated by an electrical current and glows red hot, igniting the gas when it is released into the burner.
The 1018 series hot surface ignition system is reliable, efficient, and cost-effective. It is commonly used in residential and commercial HVAC systems.
Components of a 1018 Series Hot Surface Ignition System
A 1018 series hot surface ignition system consists of several components, including:
| Component | Description |
|---|---|
| Control board | The control board is the brain of the system. It receives input from the thermostat and other sensors and controls the operation of the furnace. |
| Hot surface ignitor | The hot surface ignitor is a small, rectangular device made of silicon nitride. It is heated by an electrical current and glows red hot to ignite the gas in the burner. |
| Flame sensor | The flame sensor is a metal rod that detects the presence of a flame. If the sensor does not detect a flame within a few seconds of the gas being released, it will shut off the gas to prevent a dangerous buildup of gas. |
| Gas valve | The gas valve controls the flow of gas into the burner. It is opened by the control board when the furnace needs to be heated. |
