What's Included?
Included Components
- Gas log grate/burner assembly
- Five-piece ceramic fiber log set
- Glowing ember material
- Manufacturer-specified anchoring hardware
Optional / Separate Items
- Compatible VFDR remote controls
- Wall switches
- Thermostat accessories
- Other optional accessories unless specifically included
Vent-Free Supplemental Heating
When installed as an unvented appliance where permitted, the Flint Hill uses combustion air from the room.
- Adequate combustion and ventilation air must be provided.
- The appliance is intended for supplemental zone heating.
- It is not intended to serve as a primary whole-house heating system.
- Vent-free gas combustion produces water vapor.
- Proper sizing and room ventilation remain important.
Vented Decorative Operation
The VFDR millivolt and VFDM manual configurations can also be installed as vented decorative gas-log appliances when manufacturer requirements are satisfied.
- The fireplace damper must remain appropriately open.
- A damper clamp must be installed to prevent accidental closure.
- Thermostat operation is not approved for vented decorative appliance operation.
- The fireplace must meet all venting and installation requirements.
Canada:
The manufacturer states that this unit cannot be installed as an unvented application in Canada. Applicable Canadian installations must use the permitted vented configuration.
Flame Appearance & Glowing Embers
When the logs are correctly positioned and the burner is operating normally at full rate, the documented flame presentation includes:
-
Yellow flames above the rear burner section
-
Shorter blue flames toward the front burner section
-
Glowing ember appearance across the front burner area
- Natural variation in flame height during operation
Correct log and ember placement is essential.
Improper positioning can affect the flame pattern and contribute to sooting or other operating problems.
ODS Pilot Safety System
The Flint Hill includes an Oxygen Depletion Sensor (ODS) pilot safety system.
The system is designed to shut the appliance down if adequate fresh air is unavailable during vent-free operation.
ODS does not replace ventilation.
Adequate combustion and ventilation air must still be provided.
Glass Doors, Screens & Airflow
Glass Doors
Fireplace glass doors must remain open during operation.
Fireplace Screen
Operate the appliance with the required fireplace screen in place.
Fans & Drafts
Do not direct fans or strong drafts into the fireplace because they can alter the flame pattern.
Existing Fireplace Preparation
Before installation in an existing solid-fuel-burning fireplace, the chimney flue and firebox should be cleaned by a qualified professional.
- Remove soot.
- Remove creosote.
- Remove ashes.
- Remove loose paint.
- Verify fireplace dimensions afterward.
- Secure the burner and grate assembly properly to the fireplace floor.
A loose burner assembly can shift the logs away from their intended positions and affect combustion.

- Applicable local codes
Remember
- VFDM = manual control
- VFDT = thermostat control

- VFDT thermostat use is vent-free only
Care & Maintenance
Annual inspection and cleaning by a dealer or qualified service technician is recommended.

Flame Authority Expert Recommendation
Choose the Empire White Mountain Hearth 24" Flint Hill Gas Log Set when you want a complete five-piece ceramic fiber log and Contour Burner system with multiple control options.
The most important choice is the control configuration. Select VFDM for straightforward manual operation, VFDT for vent-free thermostat control, or VFDR when remote-ready millivolt flexibility is the priority.
Before ordering, verify the fuel type, control configuration, fireplace A/B/C/D dimensions, intended vented or vent-free installation, local code requirements, combustion-air provisions, and fireplace-door conditions.
