HPC Fire Octagon Unfinished Fire Pit Enclosure with Burner

HPC Fire Octagon Unfinished Fire Pit Enclosure with Burner

The HPC Fire Octagon Unfinished Fire Pit Enclosure with Burner (widely designated across structural builds as a Ready-to-Finish or RTF kit) is an industrial-tier, structural framing system manufactured by Hearth Products Controls (HPC). Explicitly engineered for professional builders, landscape architects, and masonry contractors, this heavy-duty system removes the complex on-site drafting phase required to frame flawless geometric corners.

Arriving with a pre-plumbed, fully integrated gas fire pit burner insert, this eight-sided chassis serves as a secure, non-combustible foundation ready to accept your signature choice of outdoor cladding.

Structural Framework & Architectural Freedom

• Ready-to-Finish Geometric Cage: Constructed around a heavy, rigid 22-gauge galvanized steel welded skeleton. This architectural layout distributes extreme weight loads evenly, guaranteeing zero structural warping, sagging, or joint separation over decades of seasonal frost shifts.

• Pre-Sheathed Hardieboard Skin: The galvanized framework arrives fully wrapped in durable, non-combustible 1/2" thick Hardieboard cement sheets. This provides an optimal, porous bonding surface that directly accepts custom exterior masonry veneers including stacked ledge stone, porcelain tile, stucco finish, outdoor brick pavers, or marble.

• Integrated Venting Infrastructure: Safety-engineered to incorporate factory-cut lower air tracks. Included structural louver covers satisfy mandatory code ventilation parameters, actively venting non-combustible fuel pockets out of the frame cavity to prevent gas pooling and back-flashes.

• Flawless Octagon Drafting: Constructing precise, symmetrical 45-degree angle stone corners on a job site requires intense labor and measurement. This pre-fabricated system arrives perfectly uniform, slashing installation time and reducing hardscape masonry labor costs.

Choose Your Core Burner Ignition Platform

This octagonal RTF enclosure package comes pre-equipped from the factory with a matching, fully certified 304 stainless steel burner array, custom selectable across three distinct ignition tracks:

• Platform A – Smart Electronic Ignition (EI - On/Off or Hi/Lo): The premier automated option. Employs a hot surface igniter (HSI) with a robust pilot flame loop and thermocouple. Features a built-in smart antenna that pairs wirelessly with the free, proprietary HPC Fire Bluetooth App, enabling total on/off or variable flame-height adjustments via a handheld remote control or smartphone from up to 20 feet away.

• Platform B – Push-Button Flame Sensing (FPPK): A battery-powered electronic pulse mechanical ignition track. Pressing the console push-switch generates high-frequency sparks to ignite the pilot. Includes an integrated internal thermocouple flame-sensing safety valve that immediately cuts down gas distribution if wind knocks the flame out.

• Platform C – Traditional Match Lit (MLFPK): The ultimate heavy-duty analog format. Completely free of internal electrical loops, battery modules, or wiring lines, this system relies on a physical match or torch wand for starting. Gas volume and thermal height are managed via a decorative solid brass key valve mounted cleanly onto the enclosure's outer face.

Technical Specifications & Sizing Configurations

• Enclosure Size Proportions: Highly ergonomic 18-inch height profile (chat-height) that lines up beautifully alongside surrounding outdoor patio sectionals and lounge chairs. Available in standard outer diameter sizes:

  • 54" Octagon Model: Fits mid-to-large hardscape landscape plans cleanly.

• Burner Layout Architecture: Comes equipped standard with HPC's iconic Penta Burner hub machine-welded from premium 304 stainless steel. Its staggered five-point port geometry draws fuel toward the center, creating a full, natural campfire-style flame presentation that looks stunning from every angle. (Upgradable to high-velocity brass Torpedo Nozzle jets for extra tall, roaring flames).

• Thermal Output Capability: Generates robust thermal heat performance ranging between 125,000 to 140,000+ BTUs depending on chosen gas dynamics and orifice tuning.
