White Mountain Hearth Fallen Timber Gas Logs
White Mountain Hearth LS30CT 30" Fallen Timber Burncrete® Gas Log Set
The White Mountain Hearth LS30CT is a 30-inch, 8-piece Fallen Timber Burncrete® gas log set designed for a compatible 30" White Mountain Hearth Slope Glaze Burner. Its irregular, layered log arrangement creates the look of naturally fallen wood while the separately selected burner determines fuel type, ignition, controls, BTU input, and final operating configuration.

Important: Log Set Only — Burner Not Included
The LS30CT includes the 8-piece Fallen Timber Burncrete® log set only. A compatible 30" White Mountain Hearth Slope Glaze Burner is required for operation and must be purchased separately.
Do not treat LS30CT as a complete heater.
Fuel type, BTU input, ignition, controls, gas pressure, and installation configuration are burner-dependent specifications.
Natural Fallen Timber Styling for a Large 30" Fireplace
The LS30CT is designed for buyers who want a less uniform, more naturally fallen wood appearance than a tightly stacked log arrangement.
Its 8-piece Burncrete® construction uses White Mountain Hearth's hand-painted detailing to create an irregular layered presentation. When correctly positioned over the compatible Slope Glaze Burner, the logs are arranged to complement the burner's flame pattern.
White Mountain Hearth's Slope Glaze Burner system uses ceramic beads to tumble gas and create flame movement through the log presentation.

What's Included?

- 8-piece manufacturer-defined log configuration
Required Separately
- Compatible 30" White Mountain Hearth Slope Glaze Burner
- Correct burner fuel configuration

- Compatible fireplace or firebox
Compatible Empire Fireboxes
White Mountain Hearth lists the LS30CT for use with the following Empire firebox models:
VFD42FB
Manufacturer-listed compatible firebox reference.
VFP42FB
Manufacturer-listed compatible firebox reference.
VFS42FB
Manufacturer-listed compatible firebox reference.
Firebox listing does not replace full compatibility verification. Confirm the burner, fuel configuration, clearances, and installation requirements for the completed system.
Compatible 30" Slope Glaze Burner Options
White Mountain Hearth offers compatible Slope Glaze Burners in multiple control configurations.
Manual
Manual burner-control configurations are available within the Slope Glaze family.
Millivolt
Millivolt configurations provide alternative control options depending on the burner model.
Variable Flame
Variable-flame models provide adjustable flame-height functionality.
Intermittent Pilot
Intermittent-pilot configurations provide another ignition and control option within the burner family.
BTU Output Comes From the Burner
The LS30CT logs do not have an independent BTU input rating.
White Mountain Hearth literature lists up to 38,000 BTU input for applicable 30" Slope Glaze Burners.
Do not describe LS30CT alone as a 38,000 BTU heater.
That figure belongs to the compatible burner system, not to the decorative Burncrete® logs.
Fireplace & Firebox Sizing
The LS30CT's 30-inch nominal size does not by itself establish fireplace fit.
Minimum fireplace dimensions vary by the exact 30" Slope Glaze Burner and control configuration selected.
Fitment rule: Verify the installation manual for the exact burner before ordering or beginning installation. Do not assume that a fireplace is compatible simply because it appears large enough for a 30" log set.
Correct Fallen Timber Log Placement Is Required
White Mountain Hearth provides a model-specific placement arrangement for the LS18CT, LS24CT, and LS30CT Fallen Timber family.
The logs must be firmly and correctly positioned in the locations shown by the manufacturer.
Flame Pattern
Correct placement supports the intended flame path around the logs.
Burner Performance
Incorrect positioning can interfere with normal burner operation.
Soot Prevention
Improper log placement can contribute to soot and other operating problems.
Do not rearrange the logs for appearance. Follow the LS30CT placement diagrams in the manufacturer installation manual.
Glowing Embers & Decorative Material
Rock wool used for the glowing-ember effect must be placed only in the designated burner area shown in the manufacturer's instructions.
- Do not apply excessive glowing-ember material.
- Do not cover burner-port areas that must remain open.
- Do not place decorative lava rock directly on the burner.
- Do not place small decorative wood pieces directly on the burner.
- Place permitted decorative material only on the fireplace or firebox floor as directed.
Vented vs. Vent-Free Installation
Vent-Free Configuration
- Use an approved compatible vent-free burner.
- Meet all combustion-air requirements.
- Follow all fireplace and clearance requirements.
- Maintain the exact log arrangement.
- Confirm local codes permit vent-free operation.
Vented Decorative Configuration
- Use an approved compatible vented configuration.
- Follow applicable fireplace and flue requirements.
- Follow all damper and burner instructions.
- Verify the installation against applicable codes.
Standards referenced by the manufacturer: The LS18CT / LS24CT / LS30CT family 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 LS30CT cannot be installed as an unvented application in Canada.
Canadian installations are limited to the manufacturer-permitted vented configuration and must comply with the applicable installation requirements.
Glass Fireplace Door Requirements
Keep fireplace glass doors open during operation.
Do not operate the applicable gas-log system with glass doors closed.
Fans, Drafts & Flame Behavior
Ceiling fans, portable fans, cold-air returns, and nearby vents can alter the burner flame pattern.
Do not allow direct drafts to push flame against the logs or firebox.
Why this matters: Disturbed flame patterns can contribute to flame impingement, improper combustion, and soot.
Existing Wood-Burning Fireplace Preparation
Before installing the LS30CT and compatible burner in an existing solid-fuel-burning fireplace, the fireplace and chimney must be properly cleaned.
- Remove soot.
- Remove creosote.
- Remove ashes.
- Remove loose paint.
- Use a qualified chimney cleaner.
- Verify all burner and fireplace requirements before installation.
Initial Operation After Installation
After installation is complete and the logs and ember material are correctly positioned, White Mountain Hearth instructs users to operate the burner on high for a minimum of three continuous hours.
Open windows or doors as needed during this initial period to allow excess heat and temporary odors to escape.
Initial-break-in purpose: The high-burn period helps burn off temporary foreign materials such as dust or paint overspray.
Installation & Safety Requirements
- Gas piping, equipment installation, replacement, service, and repair should be performed by qualified personnel.
- Follow the manufacturer instructions for the exact burner.
- Confirm fireplace or firebox compatibility before ordering.
- Use only approved log components.
- Do not alter the prescribed Fallen Timber arrangement.
- Keep burner-port areas unobstructed.
- Do not place decorative lava rock or wood pieces directly on the burner.
- Keep fireplace glass doors open during operation.
- Do not allow drafts to alter the flame pattern.
- Do not use unapproved blower inserts, heat exchangers, or other accessories.
- Keep combustible materials, gasoline, and flammable vapors away from the appliance.
If soot appears on the logs: Stop operating the system and arrange for service.

Flame Authority Expert Recommendation
Choose the White Mountain Hearth LS30CT when you specifically want a 30" Fallen Timber Burncrete® presentation and have identified a compatible 30" Slope Glaze Burner.
Its main advantage is the irregular 8-piece Fallen Timber arrangement, which gives the fireplace a more naturally fallen wood appearance than a uniform stacked-log configuration.
Before ordering, verify the exact burner model, fuel type, control configuration, fireplace dimensions, compatible firebox, vented or vent-free installation, log placement, ember placement, glass-door requirements, and applicable local codes.
