Power your large outdoor fire features with the upgraded Low Voltage Ignition System (High Capacity) from The Outdoor Plus. Built for setups up to 500,000 BTU/hr, this versatile 30V DC electronic ignition system delivers dependable, commercial-grade flame management for custom fire pits, bowls, and outdoor features.
Designed to stand up to harsh weather, it's the right choice for pool-adjacent fire features and code-compliant outdoor installations where consistent ignition and advanced safety monitoring actually matter.
Direct Replacement & Upgrade
This unit (TOP-500EIS-300-30DC) is the official replacement and upgraded model for the discontinued 12V AC version (TOP-500EIS-300-12-H). It adds enhanced 30V DC power delivery, improved potted control electronics for weatherproofing, and robust LED diagnostics.
Key Features
- Built for the outdoors. The control module is fully sealed to protect electronics from rain, humidity, and temperature swings — rated for -20°F to 175°F.
- Fast, dependable flame sensing. The nickel-plated thermocouple responds quickly and resists wind and rain better than standard flame sensors.
- Commercial-grade safety and diagnostics. Built-in LED codes help troubleshoot in the field. If internal temperatures climb past 175°F, the system shuts off automatically.
- Works with your smart home. Compatible with automated pool controllers, home automation hubs, light switches, wireless remotes, and dial timers.
- One transformer, two units. The included 240W external transformer can power up to two low-voltage ignition units at once.

- Do not connect 110V/120V directly to the ignition control box. High voltage will damage the electronic valve module. Always route main supply power through the provided 30V DC transformer.
- The transformer must be plugged into or hardwired to a GFCI outlet for safety.
- The included heat shield must be installed between the burner pan and the valve box. This prevents thermal shutdown and protects your warranty.
