A direct-vent gas fireplace is the unit most designers and builders specify for a new gas fireplace, and for a $5,000–$13,000 purchase the decisions that matter are made before you pick a model: where the vent goes, how big the wall is, whether a TV is going above it, and which look you want. This guide walks those decisions in order and ends with the two Napoleon lines we recommend and why.
The Short Answer
| You want | Buy this | From |
|---|---|---|
| A fireplace that reads as a fireplace — upright opening, brick panels, log set — for a living room, family room or new build | Napoleon Elevation X (EX36 or EX42) | $4,929 |
| A wide, low ribbon of flame on a feature wall — contemporary, with glass or driftwood media and LED accent lighting | Napoleon Vector Linear (38", 50", 62", 74") | $5,039 |
| One fireplace visible from two rooms, or a room divider | Napoleon Vector See-Through (38"–74") | $6,179 |
| No exterior wall, finished basement, or no budget for a vent run | Not direct vent — see the Monessen Artisan vent-free | $2,969 |

What "Direct Vent" Actually Means
A direct-vent fireplace is a sealed firebox behind ceramic glass. It draws combustion air from outside and sends exhaust back outside through a coaxial pipe — one pipe inside another — that runs through an exterior wall or up through the roof. Nothing from the fire enters the room. That's why it's allowed in bedrooms and tightly sealed new homes where vent-free units are restricted, why it doesn't affect indoor air or humidity, and why it needs no chimney.
The trade-off is the vent path. The pipe has to get outside, and the route (horizontal through a wall vs. vertical through a roof), the length and the number of elbows are set by the manufacturer's installation manual. Plan the vent before you frame the wall, not after.
Step 1: Vent Path — the Decision That Sets Your Budget
Horizontal through an exterior wall. The simplest and least expensive install: short run, one termination cap on the outside wall. If the fireplace sits on an exterior wall, this is usually the answer.
Vertical through the roof. Needed when the fireplace is on an interior wall, or when a deck, window or property line rules out a wall termination. More pipe, a roof flashing and more labor.
No workable path. If the vent run would mean opening a finished ceiling or roof you didn't plan to touch, a vent-free unit removes the vent entirely. Vent-free vs. direct vent, honestly compared →
Venting components are not included with the fireplace and are sized to your route. If your installer isn't sourcing them, we quote the vent kit as a separate line on the same build.
Step 2: Size the Fireplace to the Wall
Two different rules depending on the format.
Traditional (Elevation X): pick the width by the room. The EX36 (38¾" wide, 44" tall) suits standard living rooms and bedrooms; the EX42 (44¾" × 48") suits great rooms and walls over 12 ft. Both are 22" deep — that depth is the framing you're giving up.
Linear (Vector): the unit should span roughly half to two-thirds of the wall section it anchors. Vector framing widths run 53.81" (38"), 65.81" (50"), 77.81" (62") and 89.81" (74"), at 73" or 91" framing height. A 10-ft feature wall wants the 50 or 62; a 14-ft wall wants the 74. Buying a size down to save money is the regret we hear most — the wall doesn't change after installation.
| Model | Max BTU/hr | Viewing area | Framing W × H × D |
|---|---|---|---|
| Elevation X EX36 | 37,000 | Upright firebox | 38¾" × 44" × 22" (unit) |
| Elevation X EX42 | 45,000 | Upright firebox | 44¾" × 48" × 22" (unit) |
| Vector 38 | 30,000 | 40.75" × 18.62" | 53.81" × 73" × 20.13" |
| Vector 50 | 36,000 | 52.75" × 18.62" | 65.81" × 73" × 20.13" |
| Vector 62 | 42,000 | 64.75" × 18.62" | 77.81" × 91" × 20.13" |
| Vector 74 | 48,000 | 76.75" × 18.62" | 89.81" × 91" × 20.13" |
Vector see-through models are shallower (16.19" framing depth) because there's no back wall. Build to the installation manual, not to this table — we send it with every quote.
Step 3: Heat — Ambiance or a Room Heater?
Every model here is a real heater, 30,000–48,000 BTU/hr, with a modulating flame you can turn down. If you're heating the room you sit in through a Pennsylvania or Minnesota winter, that output matters and direct vent keeps the heat in the house rather than pulling conditioned air up a chimney. If the fireplace is mostly for the look, size by the wall and run it low.
Heat management options change what you can put near the fireplace. Napoleon's Dynamic Heat Control (DHC) lowers wall temperatures above the unit without a fan; the Hot Air Distribution Kit (LHAD) ducts warm air to another room. They can't be ordered together — choose one.
Step 4: Mounting a TV Above It
This is the single most common question on linear fireplaces, and it's answered by clearances, not wishful thinking. Heat rises off the glass; without heat management the wall above a 40,000-BTU unit gets hot enough to matter for a television. On both Napoleon lines, ordering the Dynamic Heat Control ($125 on the Elevation X; available on the Vector) gives the lowest possible clearance above the firebox. Decide this before framing, because the DHC changes the opening.
Step 5: Natural Gas or Propane?
Whatever is at the house. Utility line → natural gas. Tank → propane. Every model here comes in both; the wrong fuel type is the most common avoidable mistake on a gas fireplace order, which is why we confirm it before anything ships.
Step 6: The Look — Elevation X vs. Vector
Both are Napoleon direct-vent units with the same electronics (ProFlame II / eFIRE remote and app), the same President's Limited Lifetime Warranty and the same fuel options. The choice is about the room.
| Elevation X | Vector | |
|---|---|---|
| Format | Traditional upright firebox, deep-set | Linear ribbon, wide and low |
| Sizes | 36", 42" | 38", 50", 62", 74" — single-sided or see-through |
| Interior | Decorative brick, ledgestone or porcelain panels (required) + log set (required) | MIRRO-FLAME reflective panels (included) + logs, glass or media (required) |
| Lighting | Top lights + ENDLESS EMBERS modulating ember bed | Multi-color LED accent lighting |
| Best in | Living rooms, traditional and transitional homes, new construction where the fireplace is the room's anchor | Feature walls, contemporary and modern spaces, two-room installs |
| Starting price | $4,929 (EX36) / $5,549 (EX42) | $5,039 (38) to $11,459 (74); see-through $6,179–$13,189 |
| Required add-ons | Log set from $429 + panels from $369 | Media/log set (call for pricing) |
| Lead time | Ships in days | 38 and 50 ship in days; 62 and 74 about 4 weeks |
A useful shortcut: the Elevation X gas shares its rough framing with the Elevation X Electric. If you're framing now and haven't settled on fuel, frame the opening and decide later.
Step 7: What the Complete Build Costs
The fireplace is one line on the invoice. Here's the full list, so the number you plan around is the real one.
| Line | Elevation X | Vector | Who supplies it |
|---|---|---|---|
| Fireplace | $4,929–$5,549 | $5,039–$13,189 | Us — freight included |
| Required interior (panels, log set or media) | $798+ | Quoted per media choice | Us — on the same quote |
| Vent kit (pipe, elbows, termination) | Sized to your route; quoted separately | Us or your installer | |
| Front, trim, heat management (optional) | $115–$1,149 | DHC / LHAD available | Us |
| Gas line, electrical, vent installation, framing and finish | Local labor — get your installer's quote against the manual | Your licensed gas installer / contractor | |
We don't install and we won't guess at your labor. What we do is send the installation manual, clearance drawings and a complete parts list with the quote, so your installer's estimate is built on the right document and nothing is missing on install day.
New Construction? Do These Three Things Before Drywall
- Choose the model and size so the rough opening and vent route go on the plans.
- Decide on the TV / heat-management option, because it changes the framing above the unit.
- Run the gas line and a 120 V outlet to the firebox location — the ignition and blower need power.
Ordering the fireplace at framing stage, not at finish stage, is how builders avoid the four-week lead time on the larger Vectors landing on the critical path.
Direct Vent vs. the Alternatives
Vent-free: no vent at all, more usable heat, lower install cost, but restricted in some jurisdictions and room-size rated. The Monessen Artisan is the vent-free linear we recommend. Full comparison →
Electric: no gas, no vent, plugs in or hardwires, supplemental heat only. Right for bedrooms, condos and rentals. Electric vs. gas →
Gas insert: a direct-vent insert retrofits an existing masonry fireplace. We don't currently carry inserts; if you have a working chimney and want to convert it, tell us and we'll say so rather than sell you the wrong unit.
Frequently Asked
Does a direct-vent gas fireplace need a chimney?
No. It vents through a sealed pipe to an exterior wall or roof. It does need a vent path, which is the main planning constraint.
Can I put a direct-vent fireplace in a bedroom?
Direct vent is the gas format generally permitted in bedrooms because combustion is sealed from the room. Confirm with local code and the installation manual.
Does it work in a power outage?
The Vector includes a battery back-up control system for ignition. The blower needs power.
Who installs it?
A licensed gas professional handles the gas connection and venting; framing and finish is standard carpentry. Budget the installer into the project.
How does a fireplace ship?
Insured freight with liftgate and a scheduled delivery appointment, free to the lower 48. Exactly how it works →
