Reliable Push-Button Ignition SystemThe Warming Trends Mercury Ignition system replaces the need for manual lighters or matches, one push of a button and your fire feature ignites reliably. This natural gas–compatible ignitor features a built-in safety shutoff that prevents gas from flowing if the spark fails to ignite the burner. The mercury-based ignition mechanism is proven, durable technology that operates consistently across thousands of light cycles.Key FeaturesSpark Type: Mercury ignition (dependable and weather-resistant). Fuel Compatibility: Natural gas only (not propane). Safety Shutoff: Auto-cutoff prevents gas leak if spark fails. Installation: Retrofit-compatible with most Warming Trends burner systems and standard fire features.How Mercury Ignition WorksA small mercury switch completes a circuit when you press the ignition button, creating a high-voltage spark at the burner. The spark ignites natural gas flowing from your burner head. If the spark fails to produce a flame within 5–10 seconds, the safety mechanism shuts off gas flow, preventing dangerous accumulation of unburned gas.InstallationInstall the mercury ignitor near your burner control area, typically on the rim or side of your fire bowl or pit. Connect the ignitor button, spark electrode, and ground wire per manufacturer instructions. Test in 5-second increments to confirm reliable ignition. If ignition fails after 2–3 attempts, check spark electrode gap and gas flow before troubleshooting further.MaintenanceMercury ignitors require minimal maintenance. Occasionally clean the spark electrode of dust or corrosion using a wire brush. Replace the spark wire every 3–5 years or if it visibly corrodes.Why Mercury Ignition?Compared to electronic ignition, mercury systems are simpler, more durable, and less affected by moisture and temperature extremes. They are ideal for outdoor applications exposed to weather.
