Monessen Mezmer Split: split firewood looks for your existing fireplace
The Monessen Mezmer Split is a vent free gas log set for the fireplace you already have. It comes 18, 24, or 30 inches wide. Pick the size on the page. The hand painted cement logs have pale split faces, with flames spread across the stack. It puts out up to 38,000 BTU for warmth in the room.
Order it for natural gas or propane. Vent free means it needs no chimney or vent pipe at all, and nearly all the heat stays in the room. Check your local code first, since some areas restrict vent free heaters. The price covers the logs and the burner. On the page you pick the size, the fuel, and the control. Light it with a match, or choose the millivolt burner and run it from a remote. Millivolt means it has a standing pilot and needs no electricity, so it keeps working when the power is out.

FAQ
How does the Mezmer Split differ from the standard Mezmer?
Same family, different firewood. The standard set stacks full-bodied logs, while the Split version styles its logs as split firewood, the look of a stack that has met an axe. The specification grid is identical between the two, so the choice is purely visual: classic rounds on one, rougher split-wood character on the other.
Is the flame display balanced across the whole set?
Balance is the design brief. Monessen describes this set as a mesmerizing balance of flames, fire distributed across the stack rather than piling into one hot spot, with plenty of heat behind it. If you have seen gas log fires where a single clump of flame dominates, this layout is the answer to that.
Can a shallow 13-inch firebox still host a real log fire?
Yes. Every length of this set needs just 13 inches of firebox depth, which brings older and slimmer fireboxes into play. Height and width minimums still apply, so verify those against the spec chart, but depth, the measurement that eliminates so many log sets, is rarely the obstacle with this one.
Can you get vent-free logs in a split-wood style?
You can; this set exists precisely for that taste. Among ventless gas logs, the Mezmer Split takes the split-firewood route and pairs it with hand-painted finishing for a personal touch. You get the informal, work-of-the-woodpile look without giving up the convenience of gas.
What finish does the burner hardware wear?
Sleek black. The burner beneath the logs is finished in black so it sits quietly against brick or stone and lets the split stack and the flames carry the scene. The set also arrives remote ready, should you later pair the millivolt version with a hand-held control.
Can I go bigger than the 18-inch version?
Two steps bigger. The set is also offered in 24-inch and 30-inch lengths, each for natural gas or propane, all wearing the same split-log styling. Larger lengths need wider openings, so check the minimum width for the size you are considering before committing to the most dramatic stack.
Is this a complete fire, or an add-on to the standard set?
Complete. The Mezmer Split ships as its own vent-free package, logs matched with their own burner system, and it is not an accessory that bolts onto the standard Mezmer. Pick one set or the other; each is self-contained, with its own choice of manual or millivolt ignition.
