About the Oakville 3X

Questions on This Model

What to Ask about this one

We don't print sizes and output here on purpose—they depend on your wall, and a wrong number costs you a trip. These are the questions that get you a straight answer in about a minute at the counter.

Can I run the Oakville 3X on a red air day?

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.

Does Utah require anything special to install the Oakville 3X?

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.

Insert or zero-clearance—which am I buying?

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 Insert unit, so neither rule quite applies—your shop will walk the placement with you.

Will it work when the power goes out?

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.

What should I bring to the showroom?

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.
