Empire White Mountain Hearth Super Stacked Wildwood Gas Logs
Empire White Mountain Hearth LS24WRS 24" Super Stacked Wildwood Refractory Gas Log Set
The Empire White Mountain Hearth LS24WRS is a 24-inch, seven-piece Super Stacked Wildwood refractory gas log set designed for compatible 24" Empire Slope Glaze burner systems. Its individually positioned rear, front, center, and top logs create a fuller naturally stacked wood-fire appearance while allowing the burner, Natural Gas or Propane fuel configuration, ignition, controls, and operating setup to be selected separately.

Important: Log Set Only — Burner Not Included
The LS24WRS includes the seven-piece Super Stacked Wildwood refractory log set only. A compatible 24" Empire Slope Glaze burner must be selected separately to create an operating gas-log system.
System specifications come from the burner:
BTU input, fuel type, ignition, control system, remote capability, gas pressure, and flame adjustment are determined by the separately selected burner—not by the LS24WRS logs.
Layered 24" Super Stacked Wildwood Fireplace Presentation
The LS24WRS is designed for homeowners who want a substantial stacked-log appearance instead of a minimal gas-log layout.
Its seven individually positioned logs build depth across the rear, front, center, and upper areas of the fireplace. The arrangement works with the prescribed flame path of compatible Empire Slope Glaze burners.
Empire specifies the placement of each log because correct positioning directly affects flame appearance, burner performance, and cleaner operation.

Not a universal 24" log set: Confirm the exact burner model, fuel configuration, controls, fireplace dimensions, and intended installation before ordering.
Natural Gas or Propane?
The LS24WRS logs themselves are not fuel-specific. Fuel type is determined by the compatible burner installed beneath them.
Natural Gas
Use the exact Natural Gas version of the compatible Empire Slope Glaze burner.
Propane / LP
Use the exact Propane version of the compatible Empire Slope Glaze burner.
Do not assume fuel conversion is permitted.
The supplied Empire burner instructions state that the gas appliance must be used with the gas type shown on its rating plate and that field conversion to another gas type is not permitted on the applicable models.
Compatible 24" Burner Performance
The LS24WRS does not have an independent BTU rating. Heating performance comes from the selected burner.

Specification distinction: BTU input, gas pressure, flame adjustment, ignition, and remote capability are burner specifications—not LS24WRS log specifications.
Fireplace Fit & Minimum Firebox Requirements
Do not determine compatibility from the 24-inch nominal log size alone. The complete burner-and-log system must fit the fireplace.
For documented VFSE-24 and VFSV-24 installations, Empire provides the following A/B/C/D minimums:
| Manufacturer Diagram Reference |
Minimum |
| A |
23" |
| B |
14" |
| C |
30" |
| D |
18" |
Use the manufacturer diagram to interpret A–D. These are burner-installation dimensions and are not physical LS24WRS log dimensions.
Compatible Fireplace Types
The supplied Empire burner documentation identifies applicable installation in:
- Solid-fuel-burning masonry fireplaces
- Applicable UL 127 factory-built fireplaces
- Listed ventless firebox enclosures
Factory-built fireplace restriction: Do not install an unvented burner in a factory-built fireplace whose manufacturer instructions state that unvented gas logs have not been tested or are not permitted.
Correct LS24WRS Log Placement
The seven logs are not intended to be arranged arbitrarily. Empire requires the manufacturer-prescribed placement sequence.
| Step |
Log |
Placement |
| 1 |
Rear Left — Log A |
Place on the left rear pin of the rear log support. |
| 2 |
Rear Right — Log B |
Place on the right rear pin of the rear log support. |
| 3 |
Front Right — Log C |
Place on the two right-front pins on the burner pan. |
| 4 |
Front Left — Log D |
Place on the two left-front pins on the burner pan. |
| 5 |
Center — Log E |
Position using the corresponding recesses in the left rear and left front logs. |
| 6 |
Top Left — Log F |
Position using the manufacturer-specified bosses and recesses. |
| 7 |
Top Right — Log G |
Position using the corresponding recesses in the center and right-rear logs. |
Do not rearrange the logs for appearance. Empire states that proper log positioning is critical to burner performance. Improper or unstable placement can contribute to sooting and other operating problems.
Vented vs. Vent-Free Installation
Vent-Free Configuration
- Use an approved compatible vent-free Slope Glaze burner.
- Provide required combustion and ventilation air.
- Meet fireplace and combustible clearances.
- Maintain the prescribed log arrangement.
- Verify local vent-free requirements before installation.
Vented Decorative Configuration
- Use an approved compatible vented appliance configuration.
- Maintain the required working flue.
- Follow the applicable damper requirements.
- Follow the burner and fireplace manufacturer instructions.
Manufacturer standards noted: The supplied Super Stacked Wildwood documentation references ANSI Z21.11.2 for unvented heaters and ANSI Z21.60 for decorative vented appliances for solid-fuel-burning fireplaces.
Canadian Installation Restriction
The LS24WRS cannot be installed as an unvented application in Canada.
Empire limits Canadian installations to the applicable approved vented configuration.
Combustion Air & Ventilation
Vent-free gas heaters use room air for combustion and require adequate combustion and ventilation air.
Vent-free does not mean air-free.
Verify the complete room-volume and ventilation requirements in the applicable burner manual before installation.
Glass Fireplace Door Requirements
Keep fireplace glass doors open during operation.
Empire also instructs installers to consider the opening of the glass-door frame when determining the minimum usable front opening of the firebox.
Fans, Drafts & Flame Behavior
Do not allow ceiling fans, portable fans, air registers, or other direct drafts to blow into the fireplace.
Air movement can alter the intended flame path, cause flame impingement, and contribute to soot or improper combustion.
Accessory caution: Do not use a blower insert, heat-exchanger insert, or other accessory unless it is approved for use with the heater.
Existing Wood-Burning Fireplace Preparation
Before installation in an existing solid-fuel-burning fireplace, Empire requires the fireplace and chimney to be properly prepared.
- Clean soot from the chimney flue and firebox.
- Remove creosote.
- Remove ashes.
- Remove loose paint.
- Use a qualified chimney cleaner where required.
- Verify the selected burner's minimum fireplace dimensions.
- Follow all burner gas-supply and installation requirements.
Initial Operation After Installation
After the logs and applicable ember material are correctly positioned, Empire instructs users to operate the burner on high for a minimum of three continuous hours during initial operation.
Open windows or doors as needed during this initial period to allow odors and excess heat associated with the first operation to escape.
Do not move the logs after correct installation. If soot appears on a log, stop operation and arrange for service rather than continuing to use the system.
Installation & Service Requirements
- Gas piping, installation, service, and related work should be completed by a qualified agency.
- Use only the gas type specified for the selected burner.
- Verify the fireplace or firebox dimensions before installation.
- Confirm the exact 24" Slope Glaze burner model.
- Follow the manufacturer-prescribed log arrangement.
- Provide adequate combustion and ventilation air for vent-free operation.
- Maintain all required sidewall, mantel, ceiling, and combustible clearances.
- Keep burner ports, controls, venturi areas, and air openings clean and unobstructed.
- Do not allow fans or drafts to disturb the flame pattern.
- Keep fireplace glass doors open during operation.
- Follow the applicable Empire manuals and local codes.

Flame Authority Expert Recommendation
Choose the Empire White Mountain Hearth LS24WRS when you want a 24" seven-piece Super Stacked Wildwood refractory presentation and have identified a compatible 24" Empire Slope Glaze burner.
Its main advantage is the layered seven-log design, which creates more depth than a simple few-piece arrangement while still allowing you to choose the burner fuel and control system separately.
Before ordering, verify the exact burner model, Natural Gas or Propane supply, control type, fireplace dimensions, vented or vent-free operating configuration, combustion-air requirements, log placement, and applicable local requirements.
