If you own an older HPC Fire Hot Wire Ignition (HWI) system, you’ve likely run into a wall recently. While the HWI systems themselves were discontinued years ago, replacement parts and the popular HWI-913 repair kits remained available as a lifeline—until early 2023.
At that point, the third-party manufacturer of the specific hot-wire igniter and repair kit ceased production. This left owners with a “dead” system and a costly dilemma: spend upwards of $2,200 for a replacement ignition system, or even more for a replacement electronic fire pit kit, including the pan & burner.
A Smarter Engineering Solution
Recognizing the need for a more affordable alternative, HPC Fire developed a technical workaround in early 2025: the HWI to EI Conversion Kit.
Instead of trying to find a discontinued part that no longer exists, this kit adapts the system to use modern, readily available components. It focuses strictly on the hardware that fails: the electronic module and the igniter, an integral component of the pilot assembly.
By retaining your existing valve box and internal plumbing, you bring the unit up to 2025 Electronic Ignition (EI) specs for $875.96 (price at the time of publication).
Compatibility Check
Before you commit to the repair, verify your pan style. This retrofit is compatible with the HWI Ignition Fire Pit Kits featuring round and square pans, as well as rectangular models fitted with H-Burners.
Important Fact: This kit is not compatible with HPC Troughs or Interlink Fire Pit Pans. If you have these specific models, a full system upgrade remains the only viable path.
You will need the gas type (Natural Gas or Propane) and the BTU range of your existing system. This info can be found on the specification plate on your HWI valve box. Once you have these details, you can select the appropriate Conversion Kit.
Why This Upgrade Makes Sense
- Supply Chain Security: By converting to EI technology, you are moving to modern, more reliable igniters that are currently in production.
- Significant Savings: The Conversion Kit offers a significantly more affordable solution compared to a complete system replacement, potentially saving thousands of dollars.
- Ease of Installation: You can download the Repair Kit Manual to review the technical steps.
- Warranty Considerations: The conversion kit carries a 90-day warranty. Existing components retain their original warranty status, so customers should consider the age and condition of their equipment before choosing between conversion and replacement.
Other Replacement Options
While the HWI to EI Conversion Kit offers the most economical solution, there are two other options worth considering, particularly for older installations.
Complete Kit Replacement
Start fresh with a complete electronic ignition kit. Every part is new and current, from the pan and burner to the gas valve, electronics, and pilot assembly.
This offers the opportunity to upgrade the burner configuration. Round and square kits are available with either a standard Penta Burner or a Torpedo Burner, while rectangular and linear kits feature Torpedo Burners exclusively.
Although more expensive, a complete replacement may be the better long-term investment for aging fire pit equipment, providing entirely new equipment with full manufacturer warranty coverage.
Electronic Ignition System Replacement
For customers who prefer to retain their existing pan and burner, HPC offers a replacement ignition system including the pilot assembly, gas valve, electronic controls, and associated ignition components.
These replacement systems serve as a direct upgrade to the latest technology. Depending on your current HWI setup, choose the specific HI/LO or On/Off Replacement System.
The replacement equipment receives full manufacturer warranty coverage, while the existing pan and burner remain subject to their original warranty terms.
