Locating My Fireplace Model
If you need replacement parts for your gas fireplace, the most important piece of information is your appliance model number. The model number allows you to identify the exact fireplace configuration and locate compatible replacement parts, manuals, and technical documentation.
Most gas fireplaces include a manufacturer rating plate that contains the model number, serial number, gas type, BTU ratings, and other technical specifications. This plate is permanently attached to the appliance and is typically located inside the lower control compartment of the fireplace.
Step 1: Locate the Lower Access Panel
The first step is to open the lower access panel or louver on the front of the fireplace. This panel provides access to the internal control compartment, where components such as the gas valve, wiring, and pilot assembly are located.
Inside this compartment, manufacturers typically place the fireplace rating plate.


Step 2: Look Near the Gas Valve and Controls
Once the lower panel is open, look for the gas control valve and other internal components. The rating plate is often mounted on the metal floor or frame of the control compartment, usually near the gas valve.
In many fireplaces, the rating plate is positioned so it can be easily read without removing internal components.


Step 3: Identify the Fireplace Rating Plate
The rating plate is usually a metal or durable label attached to the fireplace chassis. It contains important information used to identify the appliance and verify operating specifications.
Common information found on the rating plate includes:
- Manufacturer or brand name
- Fireplace model number
- Serial number
- Fuel type (Natural Gas or Liquid Propane)
- Input/BTU ratings
- Certification markings (such as UL listing)


Step 4: Locate the Model Number on the Plate
On the rating plate, the model number is typically labeled clearly as “MODEL” or “MODEL NO.” This value identifies the exact fireplace design and configuration.
In the example shown below, the model number GCDC42 NAT indicates the specific fireplace model and gas type.
When ordering replacement parts or searching for manuals, this model number is the most important identifier.
Why the Fireplace Model Number Is Important
Gas fireplaces often share components across models, but many parts are designed specifically for certain models. Using the correct model number helps ensure that replacement parts match the original equipment specifications.
With the correct model number, you can:
- Locate the correct parts diagrams
- Identify compatible replacement components
- Access the correct owner’s manual
- Verify gas type and technical specifications
If the model number cannot be located or the rating plate is damaged, identifying parts becomes significantly more difficult.

Once you locate the model number, you can use it to search for compatible parts.
