Before You Buy
Verify These First
You need a 43" round bowl insert rather than a flat-pan or other fire-pit geometry.
You want the standard penta burner shown on this page.
You will select the Fuel Type that matches the installed Natural Gas or Liquid Propane supply.
The electrical design is specifically 120VAC.
The project can accommodate up to 400,000 BTU input for the selected configuration.
The enclosure can provide the required ventilation, drainage, gas access, service access, and clearances.
The installation is outdoors and will follow the exact manufacturer drawing and local codes.
Do Not Assume
That the Standard Penta and Torpedo Penta burner versions are interchangeable product pages.
That fuel type can be changed without ordering the correct fuel-specific SKU.
That 120VAC can be substituted with the other voltage without choosing the correct product page.
That a finished fire-pit enclosure, fire media, wind guard, or cover is automatically included.
That catalog dimensions replace the model-specific installation drawing.
That modifying the appliance will preserve certification or warranty.
Burner-page distinction: This listing is only for the Standard Penta Burner. The Standard and Torpedo burner versions are intentionally separated into different product pages.
PENTA43 43" Overview
This model is designed for a built-in outdoor enclosure where the round bowl-pan format, selected burner architecture, fuel supply, ignition method, and installation requirements have all been verified before ordering.
HPC's patented five-lobe Penta geometry is designed to concentrate flame toward the center for a natural campfire-style presentation while using less fuel to reach comparable flame height than a conventional fire ring.
The round bowl pan includes a 1.25" lip intended to rest over the surrounding enclosure surface. HPC also identifies a raised burner hub and drainage weep holes as part of its outdoor water-management design.

Installation, Ventilation & Safety Requirements
This is a built-in outdoor fire pit insert, not a complete freestanding fire pit. The enclosure must provide appropriate support, ventilation, drainage, gas access, service access, and required clearances.
Enclosure Ventilation
For applicable enclosures above 200,000 BTU and up to 400,000 BTU, the supplied HPC drawing calls for four 18 sq. in. vents arranged on opposing sides.
The supplied catalog also calls for ventilation on at least two sides and a minimum 50% free-air space within the enclosure.
Clearances & Access
HPC lists a minimum 2" clearance below the insert and 36"–48" clearance to combustibles depending on insert size and application. Confirm the exact model drawing before construction.
Do not modify the appliance. HPC states that modification of the product voids certification and warranty. Follow manufacturer installation instructions and applicable local codes.
120VAC configuration: Provide the required electrical supply and follow the manufacturer wiring instructions and local electrical code for this voltage-specific product page.
What’s Included
The insert is supplied as an assembled pan-and-burner system with the related electronic-ignition components. The supplied 2026 pricing resource identifies a remote with the Hi/Lo configuration. The finished enclosure and decorative fire media are not stated as included.
Important Before You Buy
Outdoor use only.
Confirm the correct Fuel Type before ordering.
Gas piping and any flexible connector must be sized and rated for the selected SKU’s maximum BTU input.
Clearances, ventilation, drainage, and service access must be incorporated into the enclosure design.
California Proposition 65: the supplied manufacturer catalog states that this product can expose users to lead and chromium.

Manufacturer Documentation & Technical Resources
The supplied 2026 HPC Outdoor Living Product Catalog directs installers and specifiers to HPC product references for instructions and drawings. Review the exact documentation for the selected SKU, fuel, ignition, and voltage before installation or service.
Documentation rule: Use the model-specific manufacturer instructions and drawings as the controlling installation reference. The specifications on this product page are intended to support product selection and pre-purchase verification.
Flame Authority Product Guidance
The HPC Fire PENTA43 43" Standard Penta Burner Hi/Lo Electronic Ignition Round Fire Pit Insert – 120VAC is best suited to an outdoor built-in project that specifically calls for a 43" round bowl insert with the standard penta burner and hi/lo electronic ignition.
The most important ordering checks are the burner architecture, Fuel Type, maximum BTU input and 120VAC electrical configuration. These choices affect gas supply, controls, enclosure planning, and installation requirements.
Do not select the insert by diameter alone. Confirm the exact SKU, burner, fuel, ignition, gas-supply capacity, enclosure ventilation, clearances, and manufacturer installation requirements before purchase.
PENTA43 FAQs
Is the PENTA43 available for Natural Gas and Liquid Propane?
Yes, when both Fuel Type variants appear on this page. Select the variant that matches the installed gas supply; do not assume the two fuel configurations are interchangeable.
Is this PENTA43 product page for the standard burner or Torpedo burner?
This page is only for the standard penta burner. The other burner architecture is intentionally listed on a separate product page.
Does this PENTA43 require 120VAC?
Yes. This product page is dedicated to the 120VAC configuration; use the separate voltage-specific product page if the project requires the other electrical option.
What does Hi/Lo mean on this PENTA43?
Hi/Lo provides adjustable flame output. HPC states that the low setting reduces BTU input by approximately 40%.
Can the PENTA43 round fire pit insert be installed indoors?
No. HPC identifies these certified fire pit inserts for outdoor use only.
What ventilation does the enclosure need?
The enclosure must meet the ventilation requirements for the selected BTU input and installation. Do not build or close the enclosure until the exact model drawing and local code requirements have been verified.
Is fire media included with the PENTA43 insert?
The supplied resources do not state that decorative fire media is included with this insert. Do not assume media is included unless it is specifically listed with the ordered SKU.

Beautiful Mantel
The mantel required a little bit of sanding and prep before painting, but was good quality. Flame Authority did an excellent job shipping and it arrived by freight in perfect condition.
The mantel assembled well. I ended up using some construction adhesive to glue the legs on to make it a little more sturdy. I cut pocket holes in the top to attach it to the wall.
Very happy with our purchase!

Blaze Pro Portable Grill
I shopped for a grill for two people. I want it to last for ten years or more. I want it to get really hot for grilling steaks after they have been cooled sous vide. I want it to be useful also for lower temp cooking. This Blaze grill is perfect for me and my wife. Our purchase through Flame Authority was completed with no problems. I am totally satisfied with this grill and highly recommend it for anyone with similar needs.

Great heating stove
I bought the stove couple weeks ago and ended up having a chance running it a few days I am very pleased with the outcome of the amount of heat it gets out also with the amount of hours it burns at least eight hours. I would recommend this for anyone who is looking for hours of heat output. At first when I bought it I didn’t quite know if mine hopes will be for filled but now they are happy with it. I would recommend this to anyone as a trusted tester of it I am very pleased of the outcome it rains.!

Great Customer Service
I believe it was David Novak that helped me. Someone ALWAYS answered the phone and located this burner when I couldn't find it anywhere else. It almost seemed too good to be true. But it wasn't. The burner is now nestled in my new outdoor kitchen and am very pleased.
