Fire & Ice RusticStone RS42 42-Inch Smart Built-In Electric Fireplace
The Fire & Ice RusticStone RS42 is a 42-inch indoor built-in electric fireplace designed for homeowners, builders, designers, and remodelers who want the appearance of a traditional fireplace without a chimney, gas line, wood storage, or combustion. Its deep firebox presentation, pre-installed oak-style log set, mirrored back panel, adjustable flame effects, WiFi connectivity, programmable remote, and dual-voltage heating make it suitable for both new construction and fireplace retrofit projects.
The RS42 can operate from a standard 120V electrical connection or be hardwired for 240V operation. At 120V, it provides up to 5,000 BTU of supplemental heat. A properly installed 240V hardwired connection increases the maximum output to 10,000 BTU for larger rooms or applications requiring greater heating capacity.
Flame effects can operate independently from the heater, allowing the fireplace to provide visual ambiance throughout the year. Users can manage the flame, ember lighting, heater, thermostat, timer, and selected operating functions from the touch controls, included programmable remote, or compatible TuyaSmart mobile application.

Why Choose the Fire & Ice RusticStone RS42?
Traditional Fireplace Character Without Combustion
The RusticStone RS42 is designed to create the visual character of a traditional fireplace while operating entirely on electricity. It does not burn wood or gas and does not require a chimney or exhaust vent. This makes it appropriate for projects where a conventional vented fireplace is impractical, restricted, or unnecessary.
Pre-Installed Oak-Style Log Display
A one-piece oak-style log set is pre-installed in the firebox to create a familiar, traditional fireplace appearance. Individual illuminated elements within the log display add depth and visual variation while the flame system is operating.
Mirrored Firebox Depth
The mirrored back panel reflects flame movement and lighting within the firebox. This visual treatment increases the perceived depth of the fire presentation and helps the flame display appear fuller than a shallow flat-panel electric fireplace.
Adjustable Flame Presentation
Users can adjust the flame brightness and choose from three flame-speed settings. Yellow and orange flame and lighting combinations allow the appearance to be changed from a brighter active flame to a slower, more subdued presentation.
Use the Flames With or Without Heat
The flame effects are not dependent on heater operation. The RS42 can therefore be used for ambiance during warmer seasons without producing supplemental room heat.
WiFi and Programmable Controls
Built-in WiFi allows the fireplace to connect to a compatible mobile device through the TuyaSmart application. The included programmable remote and onboard touch controls provide additional ways to operate the flame, heater, lighting, thermostat, and timer functions.
120V or 240V Installation Flexibility
A standard 120V configuration supports straightforward residential installation and provides up to 5,000 BTU. For greater heating output, the fireplace can be hardwired to 240V by a qualified installer, increasing the rated maximum output to 10,000 BTU.
Designed for Installation Below a Television
The manufacturer identifies the RusticStone series as TV-safe when installed correctly. The fireplace and television must still be positioned according to the applicable installation instructions, clearances, wall construction requirements, and equipment manufacturer guidance.
Best Applications for the RusticStone RS42
The RS42 is best suited to indoor projects where a traditional firebox appearance, integrated installation, and electric supplemental heat are preferred.
- Living-room feature walls
- Family rooms and entertainment spaces
- Primary bedrooms and bedroom sitting areas
- Home offices and libraries
- Condominiums and townhomes where venting is impractical
- New-construction fireplace surrounds
- Remodeling projects
- Existing compatible fireplace openings
- Traditional or transitional interiors
- Built-in millwork and media-wall installations
- Projects requiring year-round flame ambiance
- Rooms where electric supplemental heat is appropriate
When the RS42 Is Not the Right Fireplace
Do not choose the RusticStone RS42 when the project requires an appliance outside its documented application.
- Do not install it outdoors. The RS42 is an indoor-only electric fireplace.
- Do not use it as a whole-home heating system. It is intended to provide supplemental room heat.
- Do not expect 10,000 BTU from a standard 120V connection. Maximum 10,000 BTU output requires a proper 240V hardwired installation.
- Do not install it in a location exposed to prolonged moisture or condensation. Moisture exposure can damage the appliance and can void warranty coverage.
- Do not install it without the required framed opening and ventilation access. Restricted airflow or incorrect framing can affect safety and performance.
- Do not use external switching devices that automatically energize the heater. The manual warns against external timers, programmers, or separate switching devices that can create a fire risk if the heater is covered or positioned incorrectly.
- Do not select this model when a gas or wood-burning flame is required. The RS42 produces an electric flame effect and does not create combustion.
Flame, Log, and Lighting System
Multi-Color Flame Effects
The RS42 uses low-energy LED lighting to create its flame presentation. Yellow and orange flame combinations can be adjusted to coordinate with the log display and firebox lighting.
Seven Flame Brightness Levels
The manual control system provides seven flame-brightness settings. This allows the fire appearance to be reduced for softer evening ambiance or increased for a more prominent visual focal point.
Three Flame-Speed Settings
High, medium, and low flame-speed settings allow users to change the rate of visible flame movement. The slower setting creates a calmer effect, while the higher setting produces more active movement.
Adjustable Ember and Tray Lighting
The ember-bed and tray lighting can be controlled independently through the available controls. Multiple brightness and color combinations provide additional customization around the log set.
Optional Decorative Media
The fireplace is supplied with its pre-set log display. The manufacturer manual states that optional decorative media may be purchased separately through an authorized dealer. Do not replace or modify the supplied media arrangement unless the alternative media is approved for the fireplace and installed according to the manufacturer instructions.
Heating Performance
The RusticStone RS42 provides two electrical configurations. Actual room-heating performance depends on ceiling height, insulation, exterior temperatures, room layout, air movement, and the electrical configuration used.
| Electrical Configuration | Maximum Power | Maximum Heat Output | Manufacturer-Rated Heating Area |
|---|---|---|---|
| 120V, 60Hz | 1,400W | 5,000 BTU | Approximately 400 sq. ft. |
| 240V, 60Hz hardwired | 2,800W | 10,000 BTU | Approximately 800 sq. ft. |
Low and High Heat Modes
When operated through the remote, the fireplace includes low and high heat modes. The 120V control documentation identifies approximately 700W for low heat and 1,400W for high heat.
Thermostatic Automatic Mode
Automatic mode allows the heater to respond to a selected temperature setting. The manual lists an adjustable temperature range from approximately 59°F to 83°F, or 15°C to 28°C.
Supplemental Heat Only
The RS42 should be treated as a supplemental room heater rather than the sole heating source for a residence. Select the electrical configuration based on the room, climate, installation design, and available branch circuit.
Smart, Remote, and Manual Controls
WiFi Mobile App Control
The RS42 includes a WiFi module and can be paired with the TuyaSmart application. During setup, Bluetooth, WiFi, and location access may need to be enabled on the mobile device. The phone should remain close to the fireplace while pairing, and a stable compatible WiFi signal is required.
Depending on the app interface and connected configuration, users can access fireplace power, temperature, flame lighting, ember-bed lighting, flame speed, heating, and timer functions.
Programmable Remote Control
The included remote provides access to power, heater operation, temperature, flame lighting, tray lighting, mood lighting, flame speed, countdown timing, and weekly timer functions.
Seven-Day Timer
The programmable remote supports day-specific startup and shutdown settings. Timer programming must be completed and used according to the remote-control instructions.
Countdown Timer
The fireplace supports timed shutoff operation. Available timer settings vary by the control method, with remote settings extending up to eight hours.
Onboard Touch Controls
Touch controls located on the appliance provide direct access to power, flame brightness, ember-bed brightness, timer, heater, and temperature settings without requiring the remote or mobile app.
Installation Options and Requirements
Built-In Installation
The RS42 can be framed into a wall for a finished built-in appearance. The fireplace is inserted into the prepared opening and secured at the designated side mounting locations. The installation must preserve the required air intake and ventilation areas.
Insert and Retrofit Applications
The RusticStone design can be used in compatible existing fireplace openings when the opening provides the necessary dimensions, depth, electrical service, dryness, airflow, and access. Measure the opening before ordering and compare it with the appliance and framing dimensions below.
120V Plug-In Installation
The fireplace can be tested and operated from a properly grounded 120V, 60Hz electrical outlet. The manual requires a 15-amp branch circuit and recommends a dedicated circuit to reduce the risk of a tripped breaker or blown fuse.
240V Hardwire Installation
A 240V hardwired connection is required to access the maximum 2,800W and 10,000 BTU output. When the fireplace is hardwired, the factory power cord must be removed. Hardwiring must be completed by a qualified person in accordance with the wiring diagram and applicable electrical codes.
Framing and Clearance Guidance
Prepare a framed opening that accommodates the specified rough-opening dimensions. The installation manual instructs installers to leave at least 1/4 inch around the edge of the appliance and to position the fireplace at least 3 feet from combustible materials such as curtains, furniture, bedding, paper, and clothing.
Wall materials and construction methods vary. Consult a qualified builder or installer before cutting, modifying, or framing the installation wall. All new wiring must comply with applicable local and national regulations.
Location Requirements
- Select a dry indoor location that is not prone to moisture.
- Avoid locations where direct sunlight will wash out the flame display.
- Keep the power cord away from traffic areas and trip hazards.
- Do not cover the cord with rugs, runners, or carpeting.
- Maintain access to the fireplace for future service and removal.
- Do not block the air intake located at the lower portion of the appliance.
- Test the fireplace before completing permanent framing or finish work.
Optional RS42 Trim Configurations
Optional trim configurations allow the RS42 to be adapted to different fireplace openings and finished surround designs.
RS42 Three-Sided Trim
Choose a three-sided trim when the fireplace is installed at floor or hearth level and the lower edge does not require a finished trim return. Confirm opening dimensions and trim compatibility before ordering.
RS42 Four-Sided Trim
Choose a four-sided trim when all four sides of the fireplace opening remain visible or when the installation is raised above the floor. Confirm the required finished coverage before selecting the trim configuration.
Optional trim kits are not represented as included unless specifically stated in the selected product configuration. Verify the exact fireplace and trim package before purchase.

Let customers speak for us
from 4074 reviewsI was able to get a Novus 33 in brick refractory back for my NG Novus fireplace insert. Novus is a high demand item and Flame authority was only supplier without a huge delay from manufacturer. I recommend them for all fireplace needs.
Great service and great product
Product is great, free shipping was good, and unpacking and installing it was easy. Customer support was great too, both with the sales and shipping carrier. After much research…the Modern Flames Redstone is the one.
A+ = both the sale, the shipping process, and the product
I purchased burner and fire box. I emailed and spoke with Jim . He helped me from start to finish. Great service
The mantel required a little bit of sanding and prep before painting, but was good quality. Flame Authority did an excellent job shipping and it arrived by freight in perfect condition.
The mantel assembled well. I ended up using some construction adhesive to glue the legs on to make it a little more sturdy. I cut pocket holes in the top to attach it to the wall.
Very happy with our purchase!
I shopped for a grill for two people. I want it to last for ten years or more. I want it to get really hot for grilling steaks after they have been cooled sous vide. I want it to be useful also for lower temp cooking. This Blaze grill is perfect for me and my wife. Our purchase through Flame Authority was completed with no problems. I am totally satisfied with this grill and highly recommend it for anyone with similar needs.
Came as advertised and without any delays. Arrived quickly. No issues and would buy from flame authority again.
I wanted to make sure of the size and features of this oven. I called Flame Authority and Mary answered the call. She gave me all the details and I was really amazed coz she really knows what she is selling. Expert with sales and communication. Thumbs Up!
I bought the stove couple weeks ago and ended up having a chance running it a few days I am very pleased with the outcome of the amount of heat it gets out also with the amount of hours it burns at least eight hours. I would recommend this for anyone who is looking for hours of heat output. At first when I bought it I didn’t quite know if mine hopes will be for filled but now they are happy with it. I would recommend this to anyone as a trusted tester of it I am very pleased of the outcome it rains.!
Nice , polite and helpful, when you would call with questions.Fireplace looks nice and throws a decent amount of heat , just a bit of a delay in delivery. Ended up getting it End of January, right before guests arrived. But still only took 3 weeks to get. Thank you Flame Authority !!!
I didn't expect to have this fireplace earlier than the lead time they promised. It looks stunning in my living room and now we are prepared for the upcoming winter season! I am happy with all the updates! Customer service representatives keep on updating me with the process of my order until delivery they are checking it for you! 10 stars for Flame Authority!
Simply beautifully designed. Very efficient. Looks gorgeous in our mid century modern home in a corner space. Will save us $$$ on electric heat bills and is easy to clean with fireplace glass cleaner.
I believe it was David Novak that helped me. Someone ALWAYS answered the phone and located this burner when I couldn't find it anywhere else. It almost seemed too good to be true. But it wasn't. The burner is now nestled in my new outdoor kitchen and am very pleased.
Thank you for a very smooth transaction. the remote is very useful. It is very easy to install
