Majestic Vesper 42" Outdoor Vent Free Gas Firebox
A traditional 42" by 27" opening, lined in concrete panels and burning on the Lumonessen Outdoor burner. The Majestic Vesper 42" is an outdoor vent-free gas firebox: two fire screens and the hood come with it, and it needs no chimney or vent pipe. The burner and logs are not included with the firebox. Your fuel choice above adds the Lumonessen Outdoor burner with its grate and volcanic rock; then choose a stacked or herringbone interior and a Mezmer, Mezmer Split or Mountain Oak log set. It frames into an opening 48-1/2" wide, 34-1/4" high and 19-3/4" deep, and is priced from $2,808, with a Limited Lifetime warranty on the body and firebox.
Choose the Vesper 42" if you want a classic log fire on a patio, porch or outdoor wall with no vent pipe to run. Pick a traditional or herringbone concrete interior and one of three log styles, and set it on a deck or slab inside its own framing or a wall.
It is not right for you if you want a long, low ribbon of flame. The Vesper 42" is built around a traditional 42" by 27" opening, so the fire reads as a log fire in a firebox.
Specifications
The framed opening is 48-1/2" wide, 34-1/4" high and 19-3/4" deep; the firebox itself is 48" wide at the front, 37-1/8" at the back, 34" high and 20" deep, and weighs 155 lb. It needs 0 in. clearance at the back and sides, at least 9 in. from the opening to a side wall, 42 in. to the ceiling and 36" clear in front. Framing, including a corner layout, is in Figure 3.3 on page 9 of the installation manual, clearances in Figure 3.4 on page 10, and mantel clearances in Figures 7.1 to 7.4 on pages 16 and 17. The burner needs no household power; if you wire the firebox junction box, it takes an unswitched 110-120 VAC circuit.
The Vesper 42" vs. the 36"
The Vesper 36" narrows the opening to 36", frames 42-1/2" wide and takes the 24" log sets, on the same burner. This 42" is from $2,808 and fits a 48-1/2" wide framed opening.

Answers to common questions
What’s included, what’s required, and what’s optional?
-
Included in the box: Concrete interior panels lining the back and sides of the firebox; Two fire screens on screen rods; Hood and a 3 in. non-combustible board for above the unit; Limited Lifetime warranty on the body and firebox.
-
Required to complete the installation, purchased separately: Burner - not included with the firebox; your fuel choice above adds the Lumonessen Outdoor burner for that fuel, with its grate and volcanic rock; Enclosure - stand-alone framing or a built-in wall, finished in non-combustible material and sealed at every joint; see Figure 3.3 on page 9 of the installation manual; Gas Line - natural gas or propane to the burner, with a manual shutoff valve, run by a qualified installer.
-
Optional: Log Set - not included with the firebox; add Mezmer, Mezmer Split or Mountain Oak 30" logs above, or select No Thanks. The Torch Guys recommend 24" - 30" log sets for this firebox; Stainless steel mesh cabinet style doors and two drain pans, sold below; the fireplace operates fully without them.
Where can the Vesper 42" be installed?
Outdoors only, with the Lumonessen Outdoor burner sold here. It can go inside walls with no roof, under a roof with no more than two side walls, or under a roof with three side walls as long as at least 30 percent of the perimeter stays permanently open; 14x18 or 16x18 screen mesh may cover the open sides. It can stand alone or be built into a wall, on a flat wood, composite or non-combustible surface that runs its full width and depth.
Does it need a chimney or vent pipe?
No. The Vesper 42" is a vent-free firebox, so it needs no chimney or vent pipe, and its front opening must never be obstructed or its combustion and ventilation air restricted. Keep 42 in. to the ceiling, at least 9 in. from the opening to a side wall, and 36" clear in front; clearances are drawn in Figure 3.4 on page 10 of the installation manual.
Can it run on propane?
Yes. Choose Propane above and the page includes the propane Lumonessen Outdoor burner, LUM-OD-PM, in place of the natural gas burner, at the same price. It runs up to 38,000 BTU/hr on either fuel, turning down to 31,000 on propane and 19,000 on natural gas. In the U.S. the input is reduced 4% for each 1,000 ft above 2,000 ft.
What is the difference between the interior panel choices?
Both line the back and sides of the firebox in concrete panels. Traditional Concrete Refractory is the VOFB42T-B, laid in a stacked pattern; Herringbone Concrete Refractory is the VOFB42H-B, laid in a herringbone pattern. The panels are built into the firebox you order.
How does it handle rain?
The Vesper is made to run outdoors in rain, and drain holes in its base let the water through. It sheds moderate water but is not waterproof, so the enclosure has to be finished in non-combustible material, sealed at every joint and let that water out at its lowest point. Majestic sells a drain pan and a flat drain pan, below. Glass doors must not be fitted to it.
Can I put a mantel above it?
Yes. How high it has to sit depends on the mantel's depth and on whether it is combustible: Figures 7.1 and 7.2 on pages 16 and 17 of the installation manual chart it, and Figures 7.3 and 7.4 on page 17 cover mantel legs. You can also send us your mantel depth. We're here to help!
