Our take on the Vent-Free IP 28000 BTU Fireplace Insert

This is a ventless gas fireplace insert rated up to 28,000 BTUs, sized to drop into an existing masonry or factory-built firebox. It runs on propane or natural gas with a millivolt valve, on/off switch, thermostat and blower, and it carries a fine mesh barrier screen plus an oxygen depletion sensor for automatic shutoff. The cast-iron look and banded brick ceramic liner aim to mimic a real masonry firebox. Against vented inserts it installs without a chimney flue, which suits rooms where running venting is impractical, but ventless units release combustion moisture and require a clear, code-approved firebox and local vent-free rules.

Questions and answers

Does this insert need a chimney or vent?

No. It is ventless, so it does not use a flue. It still must sit in a code-compliant firebox, and some states and cities restrict vent-free gas appliances, so check local rules first.

Can it run on natural gas or propane?

It is offered for both propane and natural gas, and the 28,000 BTU rating is stated for propane. Confirm the fuel version you order matches your home's supply, since the two are not interchangeable.

What size firebox does it fit?

The unit is about 15 inches deep and 22.18 inches high, so measure your existing firebox opening and compare against the insert's dimensions and clearance requirements before buying.

Does it have a thermostat and blower?

Yes. It uses a millivolt valve with an on/off switch, a thermostat and a blower, so it can cycle heat and push warm air into the room rather than relying on radiant heat alone.

Is it safe to leave running unattended?

It has an oxygen depletion sensor that shuts the unit off if oxygen drops, and a fine mesh barrier screen. Follow the manufacturer's clearances and never block the firebox openings.

How does it compare with a vented insert?

Vented inserts exhaust combustion gases outside and handle larger fireboxes, while this ventless unit installs without a flue and adds moisture indoors. Choose ventless for simple installation, vented for a more sealed, drier burn.
