Empire White Mountain Hearth Super Sassafras Gas Logs
Empire White Mountain Hearth LS24RSS 24" Super Sassafras Refractory Gas Log Set
The Empire White Mountain Hearth LS24RSS is a 24-inch, seven-piece Super Sassafras refractory gas log set designed for compatible 24" Empire Slope Glaze burner systems. Its hand-painted refractory logs create a substantial traditional wood-fire appearance, while the separately selected burner determines the fuel type, ignition, controls, BTU input, and vented or approved vent-free operating configuration.

Important: Log Set Only — Burner Not Included
The LS24RSS includes the seven-piece decorative refractory log set only. A compatible 24" Empire Slope Glaze burner is required separately to create an operating gas-log system.
Do not select by fuel type alone.
The logs themselves are not Natural Gas- or Propane-specific. The exact burner determines fuel type, ignition, controls, BTU input, and the approved installation configuration.
Layered 24" Super Sassafras Fireplace Presentation
The LS24RSS is designed for homeowners completing or upgrading a compatible Empire gas-log system who want a fuller, traditionally styled refractory log arrangement.
Its seven separately positioned logs create visual depth across the rear, front, center, and upper areas of the fireplace rather than relying on a single molded assembly.
Correct log placement is especially important. Empire prescribes the location of every log because incorrect positioning can alter flame movement, interfere with burner operation, and contribute to soot.

Not a universal 24" log set: Confirm the exact burner model before ordering. Burner family, fuel type, control system, and installation requirements all matter.
Natural Gas or Propane?
The LS24RSS logs are not fuel-specific. Natural Gas or Propane operation is determined entirely by the selected compatible burner.
Natural Gas
Use the corresponding Natural Gas version of the approved 24" Slope Glaze burner.
Propane / LP
Use the corresponding Propane version of the approved 24" Slope Glaze burner.
Do not assume field conversion is allowed. Select the burner specifically designed and rated for the fuel supplied to the installation.
Compatible Burner Output
The LS24RSS does not have an independent BTU rating because it is the decorative log set rather than the gas-burning appliance.

Specification distinction: BTU input, turndown, gas pressure, ignition, and controls belong to the selected burner—not to the LS24RSS logs.
Fireplace Fit & Minimum Dimensions
Do not determine fireplace compatibility from the 24-inch nominal log size alone. Required firebox dimensions depend on the burner configuration.
For applicable VFSE-24 and VFSV-24 installations, Empire lists the following minimum dimensions:
| Minimum Rear Width |
23" |
| Minimum Depth |
14" |
| Minimum Front Width |
30" |
| Minimum Height |
18" |
Burner-specific dimensions: These measurements apply to the documented VFSE-24 and VFSV-24 configurations and should not be treated as universal LS24RSS firebox dimensions.
Vented vs. Vent-Free Installation
Vent-Free Configuration
- Use an approved vent-free 24" Slope Glaze burner.
- Provide adequate combustion and ventilation air.
- Verify firebox and combustible clearances.
- Maintain the exact seven-log arrangement.
- Follow the selected burner's instructions.
- Verify that local regulations permit vent-free operation.
Vented Configuration
- Use an approved compatible vented burner.
- Maintain the required fireplace flue configuration.
- Follow applicable damper requirements.
- Follow the exact burner and fireplace instructions.
- Verify all venting and clearance provisions.
The logs do not determine venting. The completed system's operating configuration depends on the selected burner, fireplace, installation, and applicable codes.
Canadian Installation Restriction
The LS24RSS cannot be installed as an unvented application in Canada.
The supplied manufacturer instructions limit Canadian installations to an approved vented configuration.
Correct LS24RSS Seven-Log Placement
Empire specifies an exact seven-position installation sequence for the Super Sassafras logs.
| Position |
Log |
| 1 |
Left Rear Log |
| 2 |
Right Rear Log |
| 3 |
Left Front Log |
| 4 |
Right Front Log |
| 5 |
Left Top Log |
| 6 |
Center Top Log |
| 7 |
Right Top Log |
Do not rearrange the logs for appearance. Incorrect placement can interfere with flame patterns, burner operation, and soot prevention.
Glowing Ember & Lava Rock Placement
Decorative media must be installed only where permitted by Empire.
- Do not place decorative lava rock directly on the burner.
- Do not cover large burner ports with glowing ember material.
- Use only the amount of ember material specified by the manufacturer.
- Remove previously applied loose ember material before reapplication when instructed.
- Follow the LS24RSS installation photographs and diagrams.
Why placement matters: Excessive or incorrectly positioned media can interfere with flame characteristics and burner performance.
Glass Fireplace Door Requirements
Glass doors must remain open during operation.
The manufacturer's instructions require fireplace glass doors to remain open while the gas-log system is operating.
The glass-door frame opening must also be considered when measuring the available front opening of the firebox.
Combustion Air & Airflow
Approved vent-free operation requires adequate combustion and ventilation air.
Vent-free burners use air from the room in which they are installed, so the room must satisfy the applicable manufacturer's combustion-air requirements.
Avoid Direct Drafts
Do not allow ceiling fans, portable fans, or other airflow sources to blow directly into the fireplace.
Keep Air Openings Clear
Keep burner ports, venturi areas, and required combustion-air openings free from dirt, debris, and obstruction.
Important Installation & Operating Requirements
- Installation and service should be performed by qualified personnel.
- Use only approved burner and control components.
- Verify the exact Natural Gas or Propane burner model.
- Follow the seven-log placement sequence exactly.
- Do not place additional logs or debris on the burner.
- Keep burner ports and primary-air openings clear.
- Do not allow fans or drafts to disturb the flame pattern.
- Provide adequate combustion and ventilation air for vent-free operation.
- Follow all applicable state and local vent-free regulations.
- Keep fireplace glass doors open while operating.
- Have the appliance inspected and serviced according to the applicable burner manual.

Flame Authority Expert Recommendation
Choose the Empire White Mountain Hearth LS24RSS when you specifically want a 24" seven-piece Super Sassafras refractory log presentation and already have or plan to purchase a compatible 24" Empire Slope Glaze burner.
The biggest advantage of the LS24RSS is its layered seven-log arrangement, which creates a fuller traditional fireplace appearance while allowing you to choose the burner controls and fuel configuration separately.
Before ordering, verify the exact burner model, Natural Gas or Propane fuel, control system, minimum firebox dimensions, vented or vent-free application, combustion-air requirements, log placement, ember placement, and local installation rules.
