The ProCom 36-inch universal ventless firebox is the closest match for shoppers who need a 36-inch gas-fireplace enclosure; it accepts compatible ventless gas log sets, which are separate components. The Duluth Forge is a gas-burning option with remote control, while the Touchstone and Valuxhome models are electric alternatives, not gas inserts. Check the opening dimensions, fuel and venting requirements, and local code before choosing.

ProCom 36-Inch Universal Ventless Firebox, Black
Best for: Shoppers who need a 36-inch zero-clearance firebox and plan to select a compatible ventless gas log set separately. It accepts most 18-, 24-, or 30-inch ventless gas log sets, according to the listed product details.
The firebox includes a draw screen and hood. Its listed Airflow Technology System is intended to promote heat flow. The zero-clearance design is described as installable against or recessed into a wall accessible to a gas line. The listing also says the product is assembled in the USA.
Limitation: This is a firebox, not a complete gas-log set. Confirm the required opening, clearances, log-set fit, and installation rules before purchase.
ProCom 36-Inch Universal Ventless Firebox
Best for: Buyers comparing another listing for the ProCom PC36VFC model. The product name identifies it as a 36-inch universal ventless firebox with zero-clearance design, making it relevant when the project calls for an enclosure rather than a ready-to-use gas insert.
The product name matches the black PC36VFC option above. The other listing for this model specifies acceptance of most 18-, 24-, or 30-inch ventless gas log sets, plus a screen and hood; confirm those details on this specific listing before ordering.
Limitation: The supplied information does not establish whether this listing differs in finish or included parts. It does not replace a gas log set.
Duluth Forge Dual Fuel Ventless Fireplace Insert
Best for: Shoppers looking for a ventless gas fireplace insert with remote control. The product name lists dual-fuel operation and a 32,000 BTU rating, making it a distinct choice from the ProCom firebox, which requires a separately selected gas log set.
Choose this if the listed insert format and remote control suit your project. Verify the allowed fuel types, dimensions, installation clearances, and what is included in the box using the manufacturer’s documentation.
Limitation: The supplied product information does not provide dimensions, so do not assume it fits a 36-inch opening. Its 32,000 BTU figure is not proof of suitability for every room.
Touchstone Sideline Smart Electric Fireplace
Best for: Buyers open to electric rather than gas who want a recessed fireplace with app-connected features. The listing describes a 50-inch-wide model with Wi-Fi and Alexa support, a 1,500-watt heater with thermostat, and 30 flame and ember color options.
It also lists log and crystal hearth options. This may suit a design-focused project where gas plumbing is not desired, but it is not a gas insert and does not provide gas heat.
Limitation: Its 50-inch width means it is not a direct 36-inch substitute. Check the installation opening and electrical requirements before choosing it.
Valuxhome 36-Inch Electric Fireplace Insert
Best for: Buyers seeking an electric insert with published opening dimensions. The listing gives a minimum opening of 32.6 inches wide, 8.6 inches deep, and 26.4 inches high. It describes supplemental heat for rooms up to 400 square feet, 750- or 1,500-watt settings, remote control, and overheat protection.
Additional listed details include five flame brightness levels, three top-light colors, flame-only operation, and an optional crackling sound. It uses a 120-volt supply and has a six-foot power cable.
Limitation: This is electric, not gas. Measure the full opening and compare it with both the front and back dimensions before purchase.
Buying Guide: How to Choose a 36-Inch Gas Fireplace Insert
Is a firebox the same as a gas insert?
No. The ProCom PC36VFC is a ventless firebox designed to house a compatible gas log set; the product information says the set is accepted in several sizes but does not say it is included. A gas insert is a more complete appliance category. Confirm exactly which components come with the product.
What should I measure before ordering?
Measure the existing opening’s width, height, and depth, and check the manufacturer’s required clearances. A product described as 36 inches wide may not fit a 36-inch opening. For the Duluth Forge, dimensions were not supplied here, so obtain them before deciding.
Should I choose ventless gas or electric?
Ventless gas models use gas and must meet applicable local rules and installation requirements. Electric models avoid gas connections but need an appropriate electrical supply and are not gas-heating appliances. Choose based on the existing setup, intended heat source, and project constraints.
What else should I verify?
Check fuel type, venting method, BTU output, included accessories, and professional installation requirements. Follow product instructions and local building and fire codes. Do not select a model based on nominal width alone.
