Important Safety Information

Failure to follow these instructions can result in fire, explosion, property damage, personal injury, or loss of life. Installation and service must be performed by a qualified installer, service agency, or gas supplier.

• Local Codes: Always check state and local codes for installation restrictions and requirements before purchase and installation. Some regions, such as California, prohibit the use of this product.
• Elevation Restrictions: Due to the built-in oxygen safety sensor, vent-free products may not function properly at elevations above 4500 feet. Verify local regulations and product suitability for your elevation.
• Vent-Free Operation: This is a vent-free appliance. It draws combustion air from the room and exhausts combustion products into the room. Ensure adequate ventilation as specified in the installation instructions.
• Gas Type: Ensure the appliance is configured for the correct gas type (Natural Gas or Liquid Propane) before connection. Do not attempt to convert the unit yourself.
• Clearances: Maintain proper clearances to combustible materials as specified in the installation section.
• Children and Pets: Keep children and pets away from the hot surface of the appliance.
• Carbon Monoxide: Vent-free appliances produce carbon monoxide. Install a carbon monoxide detector in the vicinity of the appliance.

Installation and Setup

Installation must be performed by a qualified professional in accordance with all local codes and the National Fuel Gas Code ANSI Z223.1/NFPA 54.

1. Pre-Installation Check:
   • Ensure the fireplace or firebox is clean and free of debris.
   • Confirm the gas supply type (LP or NG) matches the appliance's configuration.
   • Verify adequate combustion air and room size for vent-free operation.
2. Positioning the Burner:

   Carefully place the U-shaped burner assembly within the fireplace opening. Ensure it is level and centered. The "Smart Select™ Installation" feature assists in proper placement.

3. Gas Connection:

   Connect the gas supply line to the appliance's inlet. Use appropriate gas-rated sealant and ensure all connections are leak-tested using a non-corrosive leak detection solution.

4. Log Placement:

   Arrange the 6 concrete Black Forest style logs on the burner grate according to the diagrams provided in the separate log placement guide (if included) or the general guidelines below. Proper log placement is critical for efficient combustion and flame appearance. Avoid blocking the burner ports or the oxygen depletion sensor (ODS).

   • Place the largest log(s) at the base.
   • Stack smaller logs to create a natural, realistic appearance.
   • Ensure logs do not touch the burner ports directly.
5. Embers/Lava Rocks:

   Distribute the provided lava rocks or embers evenly over the burner pan, avoiding direct contact with the burner ports or pilot assembly. This enhances the glowing effect.

6. Initial Start-Up:

   After installation, perform an initial start-up to check for proper operation, flame appearance, and gas leaks. Refer to the "Operation" section for ignition procedures.

Operation

Electronic Ignition Procedure:

1. Ensure Gas Supply: Confirm the main gas supply valve to the appliance is open.
2. Pilot Light: Locate the control knob on the appliance. Turn the knob to the "PILOT" position and push it in. While holding it in, press the electronic igniter button repeatedly until the pilot flame ignites. Continue to hold the knob in for approximately 30-60 seconds after ignition to allow the thermocouple to heat up.
3. Main Burner Ignition: Once the pilot flame is stable, release the control knob. Slowly turn the control knob to the "ON" position. The main burner should ignite, producing a double yellow flame.
4. Adjusting Flame: This unit features an adjustable thermostat. Use the thermostat control (if equipped) to set the desired heat output. The flame height will adjust accordingly.

Turning Off the Appliance:

• Temporary Shut-off: Turn the control knob to the "OFF" position. This will extinguish both the main burner and the pilot light.
• Complete Shut-off: For extended periods of non-use or maintenance, turn off the main gas supply valve to the appliance.

Oxygen Depletion Sensor (ODS): Your appliance is equipped with an ODS safety pilot system. If the oxygen level in the room drops below a safe threshold, the ODS will automatically shut off the gas supply to the appliance, extinguishing the flames. If this occurs, ventilate the area and do not operate the appliance until the cause of the low oxygen level has been identified and corrected.

Maintenance

Regular maintenance ensures safe and efficient operation of your gas log insert.

• Annual Inspection: It is recommended to have the appliance inspected annually by a qualified service technician.
• Cleaning Logs: Periodically, gently brush the logs with a soft brush to remove any dust or soot. Ensure the logs are cool before handling. Do not use abrasive cleaners.
• Burner and Pilot: Keep the burner ports and pilot assembly clean and free of lint or debris. A vacuum cleaner with a brush attachment can be used.
• Ventilation: Ensure that the room where the appliance is installed has adequate ventilation as per local codes and manufacturer guidelines.
• Gas Connections: Periodically check gas connections for leaks using a non-corrosive leak detection solution.
