As outdoor living spaces continue to evolve, gas fire pits are increasingly being updated with modern ignition technologies that offer enhanced safety, convenience, and reliability. Retrofitting an existing fire pit with a contemporary HPC Fire Inspired ignition system can bring new life to an older feature—provided it is installed correctly. This article outlines the key considerations, challenges, and best practices when upgrading older fire pits with modern HPC ignition systems.

Evaluate the Existing Fire Pit Structure

Before selecting an ignition upgrade from HPC, the installer should perform a full assessment of the fire pit’s construction and internal environment. Below are critical factors to review before installation of a new HPC ignition system to ensure proper operation, safety, and reliability.

  • Ventilation: Modern ignition systems require proper cross-ventilation (minimum 18 sq. in. per side per ANSI Z21.97). Many older enclosures lack this.
  • Drainage: To protect electronic modules, valves, and wiring the interior of the enclosure must have a means of drainage to prevent a flooded enclosure. Enclosures built too tightly or fully sealed may require modification to add drainage.
  • Gas Supply Line: Ensuring proper gas supply is imperative for proper functioning, gas supply should meet the demands of the BTU loads. A retrofit may require resizing or replacing the existing gas line. HPC recommends consulting a licensed professional to verify gas supply.
  • Burner Type & Condition: Some burners from early installations are not compatible with flame-sensing systems. Contact HPC’s team of experts to verify compatibility or to inquire about upgrades to further enhance your appliance.
  • Clearances: Adherence to all manufacturer’s clearances to combustibles is imperative for safe operation. Refer to manufacturer’s installation instructions for full clearance requirements.

For a successful installation, all these factors must be addressed to prepare the HPC appliance for modern ignition components

Select the Right Ignition System for the Upgrade

Modern HPC Fire Inspired ignition options vary in complexity and functionality. The correct system depends on the fire pit size, gas type, owner preference, and site condition. HPC offers a variety of ignition systems sure to fit any of your outdoor needs.

Push-Button / Flame Sense (Manual Safety Pilot)

  • Best for: Smaller or simpler retrofits
  • Features: Pilot flame, thermocouple safety shutdown
  • Benefits: No electricity needed

Electronic Ignition (120v/24v/12v)

  • Best for: Poolside installs, wet environments, long-distance runs
  • Features: Automatic relight, flame sensing, controlled via switch/remotes
  • Benefits: Easy convenient operation and safe for proximity to water; with low voltage systems.

Smart-Controlled Ignition Systems

  • WiFi/phone app compatibility
  • Timer and emergency stop compatibility.
  • Integration with home automation systems

Important: Always select a system tested to ANSI standards for the intended application.

Electrical Considerations for Electronic Ignition

If the retrofit upgrade includes an HPC electronic ignition system, proper electrical supply must be set up. HPC offers electronic ignition system in 12v 24v and 120v electrical requirements, verify the power source on site before installing electronic ignition.

  • Confirm 12V/24V or 120V requirement
  • Ensure wiring is outdoor-rated (direct-burial cable if applicable)
  • Use watertight conduit where required
  • Install proper grounding per manufacturer recommendations
  • To protect the ignition module, proper drainage should be established.

Water intrusion is a leading cause of premature electronic ignition failure; proper drainage electrical installation prevents this.

Testing, Certification, and Safety Verification

After the installation of your HPC ignition system, the system must undergo comprehensive safety testing to ensure safe operation and installation:

  • Leak test (gas sniffer, soap solution and/or approved pressure method)
  • Ignition test (cold start and warm restart)
  • Ventilation (ensure unit operates with proper airflow in enclosure)
  • Drainage evaluation (ensure enclosure does not trap water)

As with any gas appliance any HPC retrofitted systems must meet the same safety expectations as new installations.

When a Retrofit ignition system Isn’t Recommended

In some cases, upgrading an older fire pit with a new modern HPC ignition system may not be practical or safe. Below are a few cases in which an upgrade is not appropriate .

  • The enclosure cannot be modified to meet ventilation requirements
  • The gas supply cannot be upsized or corrected
  • There is insufficient access to service electronics
  • The structure is deteriorated or unsafe
  • The project involves homemade or uncertified fire pit designs

In these cases, replacing the burner and pan assembly or replacing the fire pit—may be more cost-effective and safer.

Retrofitting an older fire pit with a modern HPC Fire Inspired ignition system is an excellent way to improve safety, convenience, and performance—but it requires careful evaluation and proper integration of gas, electrical, and mechanical components. When performed correctly, the result is a reliable, code-compliant fire feature that performs to modern standards for many years to come.
