Room Definer 100 with 24" Glass in Utah

Yes. Utah's mandatory action days restrict solid-fuel burning, not sealed gas units, so this one runs on any air quality day. That's much of why gas became the default along the Wasatch Front.

Yes—Utah requires a safety pilot on gas appliances, and has for years, so a match-lit setup isn't an option here regardless of what a national site says. Gas piping has to be done by a licensed gas-fitter, and the install needs a permit from your city building division, or the county if you're outside city limits. Every shop in this network pulls the permit and handles the inspection as part of the job.

Simple test: an insert slides into a masonry fireplace you already have; a zero-clearance unit gets framed into a wall. This one installs as a Zero Clearance Multi Side unit, so neither rule quite applies—your shop will walk the placement with you.

Most modern gas units do. Pilot-on-demand ignition carries a battery backup that takes over automatically, and some brands' pilots generate their own current and need no power at all. Ask your dealer which this one is—it's the kind of thing you want to know before you need it.

Photos of the wall or firebox, and four measurements if you already have a fireplace: front width, front height, back width, and depth. A masonry firebox tapers, so the back is usually narrower than the front—those four numbers decide which units even fit.
