A 45" traditional direct-vent gas fireplace with a 39-1/4" by 24-1/2" view of the fire. The Superior DRT4045 is sealed combustion — it draws its air from outside and vents from the top flue, through the roof or an outside wall, so it needs no chimney. Natural gas runs 31,000 BTU/hr high and turns down to 21,000, at 59.6% P4 efficiency, and the electronic ignition keeps running on four AA backup batteries when the power goes out. from $4,389.
Choose the DRT4045 if you want the widest Custom Series firebox — a 45" opening with a 39-1/4" view — and would rather pick the front yourself: the Vista Frame, Reflection and Craftsman facades are a choice on this page, not a fixed look, and the painted-black interior can stay as it comes or take a stacked ceramic or porcelain liner.
It is not right if you need a rear-vent run or cannot give the wall 43-3/4" of framing height — this firebox vents from the top only, so a low knee-wall or under-window installation is better served by the Superior DRT3000 series, which vents top or rear. And if there is no route to the roof or an outside wall at all, a vent-free or an electric model is the one to look at instead.
Frame an opening 45-7/8" wide and 23" deep with 1/2" drywall, allowing 43-3/4" of height for the top-vent installation. It sits directly on the floor — over carpet or vinyl tile, set it on a metal or wood panel the full width and depth of the appliance. Combustible mantel and side-wall clearances are read off drawings — see Figure 6 and Figure 5 on page 16 of the installation manual. Venting is 4.5"/7.5" Secure Vent rigid, Secure Flex or Z-FLEX Model GA — 6 to 60 feet of vertical run, up to three 90° elbows. Listed by PFS TECO to ANSI Z21.88, report 16-120, for bedrooms and manufactured homes, to 4,500 ft elevation on the standard orifices.
The two DRT4000 sizes share the firebox design, facade range and liner options; they differ in width and output. This 45" runs 31,000 BTU/hr high on natural gas at from $4,389, against the 40" at 28,000 BTU/hr and from $3,659. Want more fire at the same width? The DRT4245 runs 42,000 BTU/hr high in the same 45-7/8" framing width — it needs a taller 55-3/4" framed opening — at from $5,669.
Yes — every DRT4045 uses electronic intermittent pilot ignition with battery backup: external power runs it day to day, and in an outage four AA batteries in the battery holder keep the fireplace operating. The blower is the exception — it needs mains power and will not run on the batteries.
From the top flue, on 4.5"/7.5" Secure Vent rigid, Secure Flex, or Z-FLEX Model GA components — the manual approves no other manufacturer's vent. Run vertically through the roof (6 to 60 feet of vertical venting, up to three 90° elbows) or horizontally through an outside wall with the SV4.5HT-2 termination. There is no rear-vent option. Send us your wall build-up and we will size the run with you.
Combustible mantel clearance depends on how deep the mantel is — see Figure 6 on page 16 of the installation manual, and Figure 5 on the same page for combustible side walls. You can also send us your mantel depth. We're here to help! For a utility shelf above the fireplace — the kind the manual describes for locating television sets — the shelf must sit at least 52" above the base of the fireplace with Secure Vent rigid elbow venting, or 54" with Secure Flex.
Yes — one control is required and none ships in the box. Superior's wiring instructions call for an ON/OFF wall switch, a wall thermostat, or a remote control on the DRT4000-E, so plan on adding one from the controls range when you order.
Only with Superior's certified conversion kit, installed by a qualified technician — the fireplace is built for the gas type on its rating plate and is not convertible without one. That is also why this page sells dedicated natural-gas and propane models at the same price: pick the right fuel up front and no kit is needed.
Superior warrants the fireplace, 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.
