What size gas log set fits a see-through fireplace?
See-through fireboxes need a see-through-specific log set — one finished on both sides so it looks right from either room, sized to the firebox rather than a single face. You measure the opening's front width, rear width, depth, and height like any set, but you must buy logs rated "see-through" or "double-sided," never a standard single-view set that shows an unfinished back.
It has to be a see-through set
A two-sided firebox needs a see-through (double-sided) gas log set — logs finished and arranged to look right from both rooms, not a standard set with a plain, unfinished back. Drop a single-view set into a two-sided opening and one room ends up staring at the ugly side. You still size it to the firebox's width, depth, and height, the same measurements any log set needs, but the non-negotiable part is that the set itself is rated double-sided. That's the difference between a fireplace that reads beautifully from both rooms and one that only works from the couch.
How we measure it
We measure the front width, the rear width — fireboxes often narrow toward the back — the depth front-to-back, and the opening height. On a see-through, depth matters more than usual because both faces are open and the logs are viewed in the round rather than against a back wall. Those numbers pick the set size; note that a nominal "24-inch" set refers to the log length, not the opening. They also keep the burner and logs the proper clearance off the firebox walls so the flame burns clean.
Vented, ventless, and the licensed line
On a two-sided opening, vented sets are the common, worry-free choice — ambiance with the damper open. Ventless see-through sets exist but carry the usual rules: room-size BTU limits, added indoor moisture, an ODS shutoff, and restrictions in some jurisdictions and rooms — so we spec them carefully or steer you vented. Either way, connecting the fuel is licensed gas work in NC; a showroom or mason legally can't do it. We size the set, run and pressure-test the line, and permit it. Call (828) 545-0525.
