Superior DRL6048 48" Linear Direct Vent Gas Fireplace
Forty-eight inches of linear flame over Platinum crushed glass, with the blower, the floor lighting, the porcelain liner interior and the hand-held remote all standard. The Superior DRL6048 is a sealed direct-vent linear fireplace: 35,000 BTU/hr high / 23,500 low on natural gas at 62.5% P4 efficiency, venting vertically through the roof or horizontally through an outside wall on 4.5"/7.5" Secure Vent components. from $7,179, with a 20-year limited warranty on the body, firebox and barrier.
Choose the DRL6048 if you want the fully-loaded 48" linear — the blower, floor lighting, liner and remote are already in the box, so the price shown is close to the finished spec and the only decisions left are the fuel, the media bed and the liner finish.
It is not right if there is no route to an outside wall or the roof, or no power at the wall. This is a sealed direct-vent firebox with electronic ignition: it must vent outside and it needs a 120 VAC supply. For an interior room with no venting path, the vent-free Superior VRL6048 puts the same 48" linear format on a ventless platform, and an electric linear fireplace needs only the outlet.
Specifications
Frame an opening 55-5/8" wide, with 84" minimum from the appliance base to the ceiling, and do not insulate the space between the fireplace and the area above it. Keep the back 3/4" from the wrapper and the sides 1/2" (0" to the spacers). A combustible mantel follows the manual's depth chart (4" to 12" of depth), and combustible side walls may close to 8-1/4" if they project no more than 12". Listed by PFS TECO to ANSI Z21.88, report F22-797, and rated for standard orifices to 4,500 ft.
How the DRL6048 compares to the other DRL6000 sizes — and the DRL4048
The four DRL6000 sizes share the Signature Series standard kit — blower, floor lighting, porcelain liner and remote; they differ in width and output. This 48" runs 35,000 BTU/hr high on natural gas at from $7,179, against the 60" at from $10,259, the 72" at from $12,389 and the 84" at from $15,869. The same-width Superior DRL4048 (from $5,519) shares this firebox's ratings but leaves the blower and controls as separate options and carries no floor lighting — the DRL6048 is the loaded build of the two.

Answers to common questions
What’s included, what’s required, and what’s optional?
-
Included in the box: 35,000 BTU/hr high / 23,500 low (natural gas); 31,000 / 25,500 (propane, conversion kit); Electronic intermittent pilot ignition (SIT Proflame II, IPI/CPI switchable); Battery backup — four AA batteries included; Ceramic glass; Platinum crushed glass media (two 5 lb bags), installed in the media tray; Black porcelain interior liner; Factory-installed variable-speed blower and interior floor lighting; Proflame II full-function hand-held remote (batteries included); PFS TECO listed to ANSI Z21.88 (report F22-797); 20-year limited warranty.
-
Required to complete the installation, purchased separately: Venting - Secure Vent, Secure Flex or Z-FLEX Model GA 4.5"/7.5" pipe and a termination sized for your run; Gas Line and Electrical - a gas supply line and an unswitched 120 VAC, 60 Hz circuit, run by a qualified installer; this is electronic ignition only, so power is required at all times, not just for a blower.
-
Optional: A colored or textured floor media upgrade — two bags of crushed glass in another color, a 25-piece rock kit, a driftwood-and-rock kit, or a driftwood log set — over the standard Platinum crushed glass; A Black Reflective Glass liner upgrade over the standard black porcelain interior; See-Thru conversion kits, a black Linear Trim Kit, a HeatFlo heat-management kit, a Power Vent kit and an On/Off thermostat remote kit — the fireplace operates fully without them.
Will it work if the power goes out?
Yes — every DRL6048 has battery backup built in. Four AA batteries in the Proflame II battery holder take over during a line-power interruption: the unit sparks at the pilot, lights, and operates normally. The blower and the floor lighting are the exception — they stay off until line power returns. Superior recommends installing fresh batteries before each burn season so the switchover is automatic.
How do I vent it, and is the vent in the box?
The vent is sold separately, and the run is 4.5" inner / 7.5" outer pipe on the manual's approved systems only — Secure Vent rigid, Secure Flex, or Z-FLEX Model GA — with no other manufacturer's components permitted. The flue collar is on top: run it vertically through the roof or elbow it horizontally through an outside wall, and for a down-and-out run the Power Vent kit (PVK-PF2-SV4.5) is the route. Send us your wall build-up and we will size the run with you.
Can I mount a TV above it?
Yes, with the manual's clearances — keep the TV at least 12" above the fireplace opening on a flush wall, or 18" above it in a recessed wall pocket, and note the recessed pocket itself is only available with the HeatFlo kit (maximum pocket depth 3-1/2"). The HeatFlo kit is the heat-management option here: it redirects the convective heat from above the glass to a register higher on the wall. Superior gives these TV clearances as guidance only, so check your TV maker's own temperature limits too.
Can it go in a bedroom or a manufactured home?
Yes to both — the DRL6048 is listed for installation in bedrooms, aftermarket mobile homes and manufactured homes (USA, where not prohibited by local codes; grounded to the chassis in a manufactured home). Wherever it goes, keep furniture and other combustibles at least 36" from the front of the viewing area, and give it 84" from the appliance base to the ceiling.
Do I have to buy the media or the liner upgrades?
No — the firebox is complete as it ships, with the Platinum crushed glass over the burner and the black porcelain liner fitted at the factory. The upgrades only change the look. On the media bed that means two bags of Reflective Black or Reflective Blue crushed glass, the 25-piece River Rock kit, the Driftwood Pieces and Rock kit, or the Driftwood Log Set; on the interior it means the five-panel Black Reflective Glass liner kit in place of the porcelain.
How does the warranty work if something goes wrong?
Superior warrants the DRL6048 — 20 years limited on the body, firebox and barrier, one year on the burner and gas components — and The Torch Guys handles it for you: we register the appliance and, if you ever need to claim, we deal with the manufacturer on your behalf rather than handing you a phone number. Keep your invoice and the model number; we hold the rest on file.
