A fireside that follows your room.
Choose the width that works with your furniture and wall composition, then decide how the fireplace will be installed. The four nominal sizes are 50, 60, 74 and 100 inches, but the finished opening is smaller than the overall front. Keep both measurements in view: one determines the opening; the other determines how the fireplace sits against the finished wall. Choose wall mounting or recessing before the electrical connection and wall finish are completed.
Set the flame. Keep the choice.
Use the supplied remote or the on-appliance touch controls to change the presentation. Choose from ten flame colors and a fade mode, with separate ember-bed color control. Keep the flame on with the heater off when warmth is not wanted, or select low or high supplemental heat. The heater operates only while the flame is on; the controls do not provide a heat-only presentation.
Plan the opening before the finish.
Overall dimensions, the recessed body and the finished opening are different measurements. Use the exact model’s finished-opening row when planning the recess, and keep the overall front size separate. Fully recessed installation requires hardwiring by a qualified electrician. Use a dedicated 15-amp circuit; outlet location, local electrical requirements and the mounting method should be agreed before the wall is finished. The mantel, ceiling and front-of-heater clearances also remain part of the plan.
| Detail | Specification |
|---|---|
| Overall front | 59¾″ W × 17″ H × 4¾″ D |
| Recessed body | 58⅝″ W × 16⅛″ H × 4″ D |
| Finished opening | 58⅞″ W × 16¼″ H × 4″ minimum D |
| Viewing area | 55 13/16″ W × 12″ H |
The media is part of the package.
The package includes a log set and glacier crystals, along with the remote, mounting components and installation hardware listed in the included-items table. You do not need to buy a separate decorative set to complete the standard presentation. Log arrangements vary by size; follow the placement instructions for your fireplace.

Let’s get your project right.
Is the 60-inch size the opening I should frame?
No. SPS-60B has a 59¾-inch overall width and a 58⅞-inch finished-opening width. Use its 16¼-inch opening height and minimum 4-inch opening depth as well; do not frame a 60-inch opening simply from the model name.
Should I choose wall mounting or recessing first?
Yes. A wall-mounted installation and a fully recessed installation have different mounting and connection requirements. The fully recessed method calls for hardwiring by a qualified electrician. Decide on the method before finishing the wall so the power supply and access can be planned correctly.
Can I use it on a covered patio?
No. Spectrum Slimline fireplaces are for indoor use only.
Can it replace my main heating system?
No. This fireplace provides supplemental warmth. Use it alongside your home’s primary heating system.
Can I leave the flame on without heating the room?
Yes. Select the heater-off setting to keep the flame on without the heater and blower operating. The reverse is different: the heater works only while the flame is on, so this is not a heat-only appliance.
Do I need a phone to change the flame?
No phone is needed. Use the included remote or the touch controls on the upper-right part of the fireplace.
Can I change the arrangement of the supplied logs?
Arrange the logs to your liking with glacier crystals around them, following the placement steps for your fireplace size. Have the media fitted using the manual’s sequence after the fireplace is mounted in its final location. Log sets may vary by model.
Can I plug it into an extension cord?
No. The manual prohibits extension cords and power strips. It requires a dedicated circuit; discuss the outlet location and installation method with the installer before the fireplace arrives.
Can a mantel sit directly above the glass?
No. The clearance table specifies an 11.8-inch top clearance to a mantel and an 11.8-inch top clearance to the ceiling, with measurements referenced to the glass front. The installer must use the full clearance instructions and check the finish requirements; a room photograph does not establish a safe mantel or television position.
Why does the fan run briefly when I change heat settings?
The fan runs cool air for 8–10 seconds before the heater turns on and after it turns off. Keep the airflow clear during this normal heating cycle.

OUR PRODUCT ASSESSMENT
Hearth Outpost Score
8.0/10
Spectrum Slimline suits a wall where you want a long line of fire without giving up much room in front of it. Separate lighting settings let you keep the flame fairly natural and change just the glow around the media. We like that flexibility in a living room that does double duty for television and entertaining. Start with the wall depth and your normal viewing distance, then choose the width that leaves space on either side for the rest of the furniture.

What owners are saying
A 74-inch owner specifically liked the way the unit worked in a shallow wall. Another described the color options and flame appearance as the parts they enjoyed most. Those observations help explain its appeal as an everyday focal point.
What stands out
Independent flame and ember lighting gives you a useful middle ground between a bright multicolor display and a subdued evening fire.
What to weigh before buying
Check the recess detail for the actual model. Nominal stud depth alone does not account for wall finish, wiring or obstructions behind the proposed opening.
Value Consideration
Choose the width in proportion to the seating group. A larger fire occupies more wall, but the ability to adjust the look is useful even on the smaller sizes.
