A 35" linear direct-vent gas fireplace that ships with the blower, the floor lighting and the multi-function remote already in the build. The Superior DRL3535 is the Pro Series 35" linear — a 30" by 16-3/4" view of the fire over standard Platinum crushed glass media, running 18,000 BTU/hr high and 12,000 low on natural gas at 65.11% P4 efficiency, with four AA batteries backing up the electronic ignition through a power outage. It vents out the top on 4-1/2"/7-1/2" Secure Vent rigid or Secure Flex pipe, vertically through the roof or horizontally through an outside wall. from $3,999.
Choose the DRL3535 if you want the 35" linear delivered complete — the blower, floor lighting and remote are factory-standard, 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. The clean face with integrated tile stops finishes without a mantel or surround (though a surround is offered).
It is not right if you need a primary heat source — Superior designs these as supplemental heaters, and the DRL3535 tops out at 18,000 BTU/hr. For serious heat in the same linear format, step up to Superior's larger DRL4000 or DRL6000 series linears. It is also not the unit for an interior room with no path to the roof or an outside wall: this is a sealed direct-vent firebox, and a vent-free or electric linear model is the one to look at there instead.
Frame a minimum opening 35-7/8" wide — Superior recommends an extra 1/8" per side — and hold 1/2" clearance to the wrapper at the back and sides (0" to the spacers). The minimum opening height is 42" with a 12" vertical vent section then an elbow, or 31-1/2" with an elbow directly off the unit. The fireplace sits directly on the floor — on a metal or wood panel if the floor is carpet or vinyl tile — or at least 6" up if you plan the decorative surround. It is listed by PFS TECO to ANSI Z21.88 (report F19-008), for bedrooms and manufactured homes, at elevations to 4,500 ft on the standard orifices.
The three DRL3500 sizes share the Pro Series standard kit — blower, floor lighting, Platinum media and remote; they differ in width and output. This 35" runs 18,000 BTU/hr high on natural gas at from $3,999, against the 45" at from $4,499 and the 55" at from $5,119. The same-width Superior DRL2035 (from $2,789) is the value build of the two — it leaves the control, blower and lighting as separate options and ships black glass media — where the DRL3535 carries all three standard.
Yes — every DRL3535 has battery backup built in. Four AA batteries in the battery holder provide backup power for fireplace operation during an outage; the blower is the exception and stays off until line power returns. The electronic ignition normally runs on house power — a 120 VAC unswitched circuit is required — and the book calls the arrangement "electronic IPI/CPI ignition with seamless battery back-up."
Out the top only, on 4-1/2"/7-1/2" direct-vent pipe — Secure Vent rigid, Secure Flex flexible, or Z-FLEX Model GA components are the listed systems, and no other manufacturer's vent may be used. The run can go vertically through the roof or horizontally through an outside wall. Superior strongly recommends at least a foot of vertical rise directly off the top before the first elbow, and if a 90-degree elbow sits directly off the fireplace, the packaged elbow shield is required on this model. Send us your wall build-up and roof line and we will size the run with you.
Combustible mantel clearance depends on how deep the mantel is — see Figure 5A on page 16 of the installation manual, and Figure 5C on the same page for combustible side walls and mantel legs. You can also send us your mantel depth. We're here to help! A combustible utility shelf above the 35" unit (the spot people use for a television) must sit at least 47" over a Secure Vent rigid elbow, 49" over a Secure Flex flex elbow above the fireplace base, with no insulation in between; a non-combustible mantel can go at any height.
No — the firebox is complete as it ships, with the Platinum crushed glass over the burner and Superior's black painted interior as the standard finish. The upgrades only change the look. On the media bed that means a bag of Reflective Black or Reflective Blue crushed glass, the 25-piece River Rock kit, or the Driftwood Log Set sized for this 35" firebox; on the interior it means the Black Porcelain Liner Kit in place of the painted walls.
Yes — Superior catalogues stepper gas conversion kits for the DRL3535 in both directions, natural gas to propane (GCK-S-L3535NP) and propane to natural gas (GCK-S-L3535PN), and the conversion must be carried out by a qualified service agency. Buying the right dedicated model up front is still the cleaner path, so pick the fuel you have at the meter or tank today.
Superior covers the DRL3535 with a 20-year limited warranty 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.
