Components of a Dexen Electronic Ignition Pilot Assembly
1. Pilot Burner
The pilot burner is where the gas flows to produce a flame. It ignites the main burner once the system detects a safe and stable pilot flame.
2. Igniter/Electrode
The igniter generates a spark to ignite the gas coming out of the pilot burner. It is typically connected to the dexen fireplace control module, which sends a voltage to create the spark.
3. Thermocouple and Thermopile
These components are responsible for detecting the pilot flame and generating a small electrical current to keep the gas valve open. If the flame goes out, they signal the control module to shut off the gas supply to prevent leaks.
4. Control Module
The control module is the brain of the electronic ignition system. It monitors the ignition process, checks for safety issues, and controls the entire sequence of events from sparking to gas flow regulation.
How the Dexen Electronic Ignition System Works
The Dexen electronic ignition system simplifies the process of lighting a gas fireplace. When you turn on the fireplace, the control module sends a signal to the igniter to produce a spark.
The spark ignites the gas released from the pilot burner. The thermocouple or thermopile detects the pilot flame and sends a signal back to the control module to keep the gas valve open.
Once the pilot flame is stable, the system opens the gas valve to the main burner, and your fireplace lights up.
Benefits of Using Electronic Ignition Pilot Assembly
1. Energy Efficiency
Traditional standing pilots consume gas continuously, even when the fireplace isn’t in use. With an electronic ignition system, gas is only used when the fireplace is turned on, reducing energy consumption.
2. Improved Safety
Electronic ignition systems come with built-in safety features that automatically shut off the gas if the pilot flame goes out or if the system detects an issue. This reduces the risk of gas leaks and fire hazards.
3. Convenience and Ease of Use
Gone are the days of manually lighting your fireplace. With Dexen’s electronic ignition, you can control your fireplace with a switch, remote control, or even a smartphone app, depending on your system’s compatibility.
Common Applications of Dexen Ignition Systems
- Many homeowners prefer Dexen systems for their fireplaces due to their reliability and efficiency.
- In restaurants, hotels, and other commercial settings, Dexen ignition systems provide safe and efficient heating solutions.
- Dexen systems are also popular in outdoor fire pits where manual lighting can be challenging.
Step-by-Step Installation Guide
Installing a Dexen Electronic Ignition Pilot Assembly may seem complicated at first, but with the right tools and a clear understanding of the process, you can do it successfully. Below is a detailed step-by-step guide to help you through the installation process.
Tools Required for Installation
- Screwdrivers (Phillips and flathead)
- Adjustable wrench
- Gas leak detector or soapy water solution
- Wire cutters/strippers
- Multimeter (for electrical checks)
- Safety gloves and goggles
Safety Precautions to Follow
Working with gas appliances can be dangerous if proper safety measures are not taken. Follow these safety precautions to avoid accidents:
- Always shut off the gas supply before starting the installation.
- Ensure that the fireplace is disconnected from any electrical source.
- If there’s a gas leak, ensure the room is well-ventilated before proceeding.
- Check for leaks after installation using a gas leak detector or soapy water solution.
Step 1: Disconnect the Power Supply
Locate the power switch or circuit breaker that controls your fireplace and turn it off. This ensures there’s no risk of electrical shock during the installation process.
Step 2: Remove the Old Pilot Assembly
- Carefully remove the glass panel or front screen of your gas fireplace to access the internal components.
- Locate the old pilot assembly and disconnect the gas line and wiring connected to it.
- Use an adjustable wrench to unscrew the pilot assembly from its mounting bracket.
Tip: Take a picture of the wiring connections before removing the old assembly. This will help you reconnect the new assembly correctly.
Step 3: Install the New Dexen Pilot Assembly
- Position the Dexen Electronic Ignition Pilot Assembly in the same spot as the old assembly.
- Secure it using the mounting screws provided.
- Reconnect the gas line to the new pilot assembly and tighten it with a wrench to ensure a secure fit.
Step 4: Reconnect the Gas Line and Electrical Wiring
- Reconnect the electrical wiring according to the manufacturer’s instructions.
- Ensure that the connections are tight and secure to avoid any loose wiring, which can cause ignition issues.
- Use wire connectors or electrical tape to cover exposed wires.
Step 5: Test the System
- Turn on the Gas Supply: Slowly turn on the gas supply to the fireplace.
- Power On the Fireplace: Reconnect the power and switch on the fireplace.
- Check for Proper Ignition: Observe whether the pilot ignites correctly and that the main burner lights up.
- Check for Gas Leaks: Use a gas leak detector or a soapy water solution to check for leaks around the gas connections. If bubbles form, it indicates a gas leak.
Dexen Electronic Ignition Troubleshooting
Even with proper installation, you might encounter some issues with your Dexen ignition system. Below are common problems and solutions:
Problem 1: Pilot Won’t Ignite
Possible Causes:
- No gas supply
- Loose wiring connections
- Faulty igniter
Solution:
- Check that the gas supply is turned on and there are no blockages in the gas line.
- Inspect and tighten any loose wiring connections.
- If the igniter is faulty, replace it with a new one.
Problem 2: Ignition Fails After a Few Seconds
Possible Causes:
- Dirty thermocouple
- Weak thermopile
- Faulty control module
Solution:
- Clean the thermocouple with fine-grit sandpaper to remove any dirt or debris.
- Test the thermopile’s voltage output using a multimeter. If the output is below the recommended level, replace the thermopile.
- If the control module is not sending the correct signals, it may need to be replaced.
Problem 3: No Spark from the Igniter
Possible Causes:
- Damaged igniter electrode
- Disconnected or loose wiring
- Faulty control module
Solution:
- Inspect the igniter electrode for cracks or damage. Replace if necessary.
- Check all wiring connections to ensure they are secure.
- Test the control module for proper functionality. If it’s not working, replace it.
Problem 4: Control Module Malfunctions
Possible Causes:
- Power supply issues
- Faulty control module
Solution:
