MountingWall mount, recessed or built-in
A linear fire, planned around your wall.
OR52-SLIM-V2 is the 52-inch Orion Slim V2 model. Its overall appliance footprint is 52⅜″ W × 19⅝″ H × 6⁵⁄₁₆″ D; the viewing area and opening below are different measurements.
Choose wall-mounted, recessed or built-in installation before framing. Each method has its own instructions; confirm the opening and finished wall with the installer.
Know what belongs in the plan.
The fireplace includes a lit log set, crushed glass, wood chips, twigs and a remote with AAA batteries.
The supplied wall-mount bracket and built-in trim serve different installation choices. Use the exact model instructions rather than a generic mounting assumption.
A choice of ember-bed effects.
The ember bed can stay steady, vary its brightness in breathing mode, react to fireplace sounds or Bluetooth audio, or be switched off.
Brightness that responds to the room.
An adaptive sensor adjusts flame brightness as room lighting changes, with a 10–15 second response. Keep the sensor unobstructed, or adjust the brightness yourself.
See the V2 flame in motion.
The manufacturer links this Orion V2 flame clip on its Slim page. It shows the shared V2 flame presentation in a Traditional firebox; it does not show this model’s dimensions or mounting method.
Measure the opening before the finish.
Overall appliance, viewing area and finished opening are different measurements. Select the recessed or built-in method before using its depth reference; follow the complete manual for clearances and electrical requirements.
| Reference | Dimensions |
|---|---|
| Overall appliance | 52⅜″ W × 19⅝″ H × 6⁵⁄₁₆″ D |
| Viewing area | 47⅞″ W × 14⅜″ H |
| Finished opening | 50¾″ W × 19⅛″ H |
| Recessed depth reference | 6″ minimum |
| Built-in depth reference | 6½″ minimum |
Know what comes with the fireplace.
The fireplace includes the decorative media, remote and installation equipment below.
| Reference | Contents |
|---|---|
| Decorative media | Lit log set · crushed glass · wood chips · twigs |
| Control | Remote control · AAA batteries |
| Installation equipment | Wall-mount bracket · built-in trim kit · side skirt · strain relief · cover plate · suction cups · screws and drywall anchors |
Plan a properly covered outdoor location.
Only the built-in installation is approved outdoors, under a patio cover and away from direct water contact and direct sunlight. Wall-mounted outdoor installation and an uncovered patio are outside that permission.
Front and side protection must each be at least half the roof height measured from the fireplace bottom. Keep the base at least two inches above the floor; have a qualified installer confirm the full instructions and electrical requirements.
Questions to settle before installation.
Is the nominal size the opening width?
No. OR52-SLIM-V2 has an overall width of 52⅜ inches. Its finished-opening width is 50¾ inches; viewing width is 47⅞ inches. Use the appliance width for its footprint and the opening width for the selected installation method.
What are the overall appliance dimensions?
The overall appliance measures 52⅜″ W × 19⅝″ H × 6⁵⁄₁₆″ D. The finished opening and viewing area have separate measurements.
How deep should the opening be?
Allow at least six inches of depth for the recessed method or six and a half inches for the built-in method. These belong to different installation methods. Have the installer confirm the method and full requirements before framing.
Which decorative media comes with it?
The fireplace includes a lit log set, crushed glass, wood chips and twigs. Follow the installation instructions when arranging them.
Is a remote supplied?
Yes. A remote control and AAA batteries are included.
Is the built-in trim optional?
A built-in trim kit is listed among the appliance parts. That does not establish compatibility with a separately sold trim, cabinet or accessory; check each exact part number before adding it.
Can it be wall mounted?
Choose wall-mounted, recessed or built-in installation. Use the applicable instructions and supplied wall-mount bracket; the different methods do not share an identical depth reference.
Can it be installed outdoors?
Only the built-in method is approved outdoors under the manual’s patio-cover conditions. Keep the fireplace away from direct water and sunlight; this does not authorize an uncovered patio or outdoor wall-mounted installation.
How much outdoor protection is needed?
Front overhang and side protection must each be at least half the roof height measured from the fireplace bottom. The base must be at least two inches above the floor. Have a qualified installer check the complete location and instructions.
What should I confirm before ordering?
Confirm the complete V2 model, overall footprint, finished opening, mounting method, power supply and finish. For an outdoor project, also confirm the built-in method and complete front/side shelter requirements. A qualified installer should check the exact manual before work begins.
Does this V2 model include sound and reactive lighting?
Choose fire and ambient sounds, stream Bluetooth audio, and select static, breathing or reactive ember lighting. Adaptive flame brightness responds to the room’s lighting.

OUR PRODUCT ASSESSMENT
Hearth Outpost Score
8.0/10
For a front-facing media wall, the appeal of Orion Slim is how much depth the fire appears to have when you are sitting straight across from it. V2 is designed for a two-by-six wall and gives you a choice of clean-face, self-trimming or wall-mounted installation. We would look at the display in a room as dark as yours before choosing. Brightness, visible edges and reflections are easier to judge from your evening chair than in a brightly lit showroom.

What owners are saying
Two owners of the earlier Slim describe different limits of the display. One liked the overall effect but noticed a distracting edge in the picture when the room was dark. Another saw a lit screen without flames and reported that the problem returned after replacing the USB. Their comments concern the earlier display system.
What stands out
The V2 offers adjustable scenes and sound. Try one quiet, low-light setting as well as the brightest demonstration. That is the setting many people will live with most evenings.
What to weigh before buying
Decide how you want the edge of the glass to meet the finished wall. Then check the framing drawing for your width and allow for removal of the front before choosing wall panels.
Value Consideration
The upgrade makes sense when the flame picture is the point of the purchase. If you mainly want occasional warmth, compare simpler linear models before paying for the screen and audio.
