This listing includes the Crescent Hill decorative log set only. Burner/heater components, gas controls, remote controls, wall controls, gas installation components, and other accessories are not identified as included. Use the logs only with an approved compatible Superior burner system.
Realistic Vent-Free Gas Logs for Compatible Superior Systems
The Crescent Hill log set is designed for buyers completing or replacing the decorative log portion of a compatible Superior vent-free gas fireplace system.
The layered log arrangement creates a traditional wood-fire appearance while maintaining the specific placement required by the approved burner system.
Because the logs, burner, control system, and fuel configuration are separate components, buyers should verify the exact burner model, log-set size, fireplace dimensions, fuel type, and control configuration before ordering.
Compatibility matters more than nominal size: Do not select the Crescent Hill logs based only on whether an 18-inch or 24-inch set physically fits inside the fireplace.

ODS Safety Shutoff System
Compatible heater assemblies incorporate an Oxygen Depletion Sensing (ODS) safety shutoff system.
This safety feature belongs to the compatible burner/heater assembly rather than the decorative Crescent Hill logs themselves.
System distinction: Do not represent the decorative log set alone as containing the gas valve, pilot, ODS assembly, or other heater controls.
Vent-Free Operation & Combustion Air
Vent-free operation does not eliminate room-air requirements. The compatible heater uses air from the room where it is installed and requires adequate combustion and ventilation air.
Do not install the heater in a space that fails the manufacturer's combustion-air requirements. If the room does not provide the required indoor air volume, combustion and ventilation air must be provided using an approved method permitted by the manufacturer's instructions and applicable requirements.
Installation conditions can vary according to room size, fireplace construction, combustible clearances, local requirements, and the approved operating configuration.
Fireplace Fit & Clearance Requirements
Minimum firebox dimensions are only one part of determining whether the complete vent-free system can be installed.
Firebox Dimensions
Meet all minimum size requirements for the selected 18" or 24" log configuration.
Side-Wall Clearances
Maintain the manufacturer-required clearance from combustible side-wall materials.
Materials Above Opening
Follow requirements for combustible and noncombustible materials above the fireplace opening.
Mantel Clearances
Verify mantel position and clearance before installation.
Floor Protection
Follow the applicable floor-clearance requirements when combustible flooring is present.
Combustion Air
Confirm adequate room-air volume and ventilation before installation.
Physical fit does not establish safe compatibility. The complete system must satisfy firebox, clearance, ventilation, gas-supply, burner, and installation requirements.
Log Placement Is Critical
Each Crescent Hill log must be installed in the exact manufacturer-specified position using the designated mounting points, pins, notches, and placement sequence.
Use the Correct Sequence
Install logs in the order shown by the manufacturer.
Seat Every Log Firmly
Each log should rest securely in its specified position.
Do Not Mix Logs
Do not combine logs from different models or nominal sizes.
Do Not Modify Logs
Changing log shape or placement is not an approved installation method.
Check Flame Contact
Flames should not strike or impinge on the logs.
Recheck If Soot Appears
Incorrect placement can contribute to soot and improper operation.
No flame impingement: If flame strikes a log, recheck and correct the log placement according to the manufacturer instructions.
Gas Supply Requirements
The complete heater must be connected to the fuel type specified for the selected burner model.
Natural Gas
Use only a compatible natural-gas burner configuration designed for the Crescent Hill system.
Propane / LP
Use only the compatible propane/LP burner configuration and applicable regulator arrangement specified by the manufacturer.
Propane warning: Do not connect a propane/LP appliance directly to a propane supply tank. The applicable manufacturer documentation requires an external regulator for propane/LP installations.
Installation Requirements
- Installation and service must be performed by a qualified installer, service agency, or gas supplier.
- Verify the exact burner/heater model before installing the Crescent Hill logs.
- Confirm whether the required log size is 18" or 24".
- Confirm the correct natural-gas or propane/LP configuration.
- Verify the control configuration of the selected burner.
- Verify all required fireplace dimensions and combustible clearances.
- Provide adequate combustion and ventilation air.
- Secure the heater base as specified by the manufacturer.
- Confirm the burner assembly is level.
- Install all logs in the exact required positions.
- Do not modify the logs.
- Do not mix logs from different models or sizes.
- Confirm that flames do not strike the logs after installation.
- Replace any required screen, guard, or barrier before operating the system.
Safety & Operating Considerations
Read the Manual
Review the applicable installation and operation manual before installation or operation.
No Broken or Misplaced Logs
Do not operate the appliance with damaged or incorrectly positioned logs.
No Solid Fuel
Do not burn wood or other solid fuels in the fireplace while the unvented heater is installed.
Keep Flammables Away
Keep clothing, combustible materials, gasoline, and flammable vapors away from the appliance.
Avoid Direct Fan Airflow
Do not allow fans to blow directly into the fireplace and disturb the burner flame pattern.
Maintain Burner Openings
Keep burner air passages and flame openings clean.

Flame Authority Expert Recommendation
Choose the Superior Fireplaces Crescent Hill LVDCH when you are completing or replacing the decorative logs for an approved Superior vent-free gas log system and have already confirmed the exact burner configuration and required log-set size.
The most important buying decision is compatibility, not appearance alone. Confirm the 18" or 24" size, burner model, natural-gas or propane/LP configuration, control type, fireplace opening, clearances, combustion-air requirements, and log-placement instructions before ordering.
Do not use the Crescent Hill LVDCH as a universal gas-log replacement. Use only the approved components identified for the compatible Superior burner/heater system.
