Empire White Mountain Hearth LS24P 24" Ponderosa Refractory Gas Log Set
The Empire White Mountain Hearth LS24P is a 24-inch, 13-piece Ponderosa refractory gas log set designed for compatible 24" Empire Slope Glaze burner systems. Its layered multi-level arrangement creates a fuller traditional wood-fire appearance while allowing the burner, Natural Gas or Propane fuel configuration, ignition, controls, and vented or vent-free operating setup to be selected separately.
The LS24P includes the 13-piece decorative refractory log set only. The gas burner, gas valve, ignition system, controls, remote, and complete operating gas-log system are not included.
Fuller 13-Piece Ponderosa Fireplace Presentation
The LS24P is designed for buyers who want a more layered gas-fireplace appearance than a simpler few-piece log arrangement.
Its 13 separately positioned refractory logs are arranged across front, rear, middle, upper, and top positions to build depth throughout the fireplace.
Because the LS24P is the decorative log component rather than the gas-burning appliance, the final BTU input, fuel type, gas pressure, ignition system, remote capability, and operating range come from the exact compatible burner selected.

Propane / LP
Use the exact compatible Propane version of the required 24" Slope Glaze burner.
Documented 24" Burner Performance
The LS24P has no independent BTU rating. Heat input and turndown are determined by the compatible burner.
| Burner | Maximum Input | Medium Input | Minimum Input |
|---|---|---|---|
| VFSE-24 | 36,000 BTU/hr | — | 28,800 BTU/hr |
| VFSV-24 | 36,000 BTU/hr | — | 24,000 BTU/hr |

Glowing Embers & Decorative Media
The Ponderosa manual provides dedicated glowing-ember placement instructions for the LS-24P-1.
- Place glowing embers only where Empire specifies.
- Do not obstruct burner openings.
- Do not place decorative lava rock directly on the burner.

- Do not place lava rock over burner ports.
- Do not cover prohibited burner areas with glowing embers.
- Do not allow fans to blow directly into the fireplace.
- Correct drafts that push flame against logs or the firebox.
- Maintain required combustible clearances.
Glass Door Requirements
The supplied Empire Ponderosa instructions require glass doors to remain open when the gas-log system is operating.
The glass-door frame opening can also affect the usable front opening when evaluating fireplace compatibility.
Existing Wood-Burning Fireplace Preparation
Before installing the LS24P with a compatible burner into an existing solid-fuel fireplace, Empire requires appropriate fireplace and chimney preparation.
- Clean soot from the chimney flue and firebox.
- Remove creosote buildup.
- Remove ashes.
- Remove loose paint.
- Use a qualified chimney cleaner for the required cleaning.
- Follow the applicable burner instructions for damper, gas line, anchoring, and final installation.

Flame Authority Expert Recommendation
Choose the Empire White Mountain Hearth LS24P when you specifically want a 24" Ponderosa 13-piece refractory presentation and have identified a compatible 24" Empire Slope Glaze burner.
The strongest reason to choose the LS24P is its layered 13-log arrangement, which creates more visual depth than a simpler log set. But proper system selection is critical: verify the exact burner, Natural Gas or Propane fuel, control system, BTU range, fireplace fit, vented or vent-free configuration, and local requirements before ordering.
For Canadian installations, plan for an approved vented configuration only. For vent-free installations elsewhere, verify combustion-air requirements and local code acceptance before installation.
Official Manufacturer Resources
Empire LS24P FAQs
Does the Empire LS24P include a gas burner?
No. The LS24P includes the 13-piece Ponderosa refractory log set only. A compatible 24" Empire Slope Glaze burner and required controls must be purchased separately.
How many logs are included with the Empire LS24P?
The LS24P contains 13 individual refractory logs.
Is the LS24P a 24" gas log set?
Yes. LS24P / LS-24P-1 is the 24" Ponderosa refractory log set and requires an appropriate compatible 24" burner.
Can the LS24P be used with Natural Gas?
Yes, when paired with a compatible 24" Natural Gas Slope Glaze burner. The logs themselves do not determine fuel type.
Can the LS24P be used with Propane?
Yes, when paired with a compatible 24" Propane Slope Glaze burner.
Can a Natural Gas burner be converted to Propane?
Do not assume field conversion is permitted. Use the exact burner model and fuel type approved in the applicable Empire burner instructions.
Which burner families are compatible with the LS24P?
The supplied information identifies VFSE24, VFSM24, VFSR24, VFSV24, and VSR24 families. Verify the exact fuel and control version before ordering.
How many BTUs does the Empire LS24P produce?
The LS24P logs do not have an independent BTU output. Documented compatible 24" Slope Glaze burners provide up to 36,000 BTU/hr, depending on burner model and configuration.
Can the LS24P be installed vent-free?
Yes, where permitted, when paired with an approved compatible vent-free burner and installed with the required combustion air, clearances, and manufacturer requirements.
Can the LS24P be used in a vented fireplace?
Yes, when paired with an appropriate vented burner configuration and installed according to the applicable flue, damper, fireplace-preparation, and burner requirements.
Can the LS24P be installed vent-free in Canada?
No. Empire's Ponderosa instructions state that Canadian installations are limited to the specified vented configuration.
Which Empire fireboxes are listed for the LS24P?
The supplied brochure lists VFD36FB, VFP36FB, and VFS36FB. Exact burner and installation compatibility still must be verified.
Can I rearrange the 13 Ponderosa logs?
No. Install the LS24P logs only in the manufacturer-prescribed positions because incorrect placement can interfere with proper burner operation and contribute to sooting.
Why is correct log placement important?
Correct placement maintains the intended relationship between flame, logs, burner airflow, and combustion. Incorrect positioning can result in improper burning or soot formation.
Can decorative lava rock be placed directly on the burner?
No. The supplied Ponderosa instructions state that decorative lava rock or small decorative wood pieces should not be placed directly on the burner.
Can I operate the LS24P with fireplace glass doors closed?
No. Empire's Ponderosa instructions require glass doors to remain open during operation.
Can a ceiling fan affect the gas-log system?
Yes. Do not allow fans or drafts to blow directly into the fireplace because altered flame movement can contribute to improper burning and soot.
Does an existing wood-burning fireplace need to be cleaned first?
Yes. The chimney flue and firebox should be cleaned of soot, creosote, ashes, and loose paint by a qualified chimney cleaner before gas-log installation.
Should the LS24P gas-log system be professionally installed?
Yes. Gas piping, burner installation, testing, repair, and servicing should be completed by qualified personnel according to the manufacturer instructions and applicable codes.
Is the LS24P a complete gas-log kit?
No. The LS24P is the Ponderosa refractory log set only. Burner, gas controls, ignition, and other required installation components are separate.
