Williams 4163 Floorboard
The Williams 4163 Floorboard is a heavy-duty, insulated metal protection plate designed specifically for Williams hearth heaters with 50,000 and 65,000 BTU capacities. As a critical installation component for vented hearth heaters, this floorboard acts as a thermal barrier and structural support, safeguarding finished flooring from the high-temperature output and weight of the unit. It is engineered for a precise fit with Williams 5001A and 6501A enclosed front models, as well as 5002A and 6502A fireplace front models. Finished in a black powder-coat, the 35-inch by 23.5-inch metal plate offers a scratch-resistant surface that maintains its aesthetic integrity under rigorous HVAC service conditions. For contractors, installing this OEM replacement part is standard practice when placing console heaters on combustible surfaces like carpeting or vinyl to ensure local code compliance and long-term subfloor protection.
Key Benefits
- Structural Integrity: Distributes the weight of high-capacity 50K and 65K BTU units to prevent subfloor sagging or joist stress.
- Thermal Shielding: Provides essential insulation to mitigate heat transfer, preventing floor discoloration or charring.
- Universal Heater Compatibility: Designed to fit both enclosed front and fireplace front Williams console heater configurations.
- Durable Construction: Features a 1/2-inch profile and powder-coated metal for superior resistance to wear and environmental corrosion.
- Flooring Preservation: Ideal for installations over vinyl, hardwood, or carpet where direct contact with the heater base is restricted.
Common Questions
Is this floorboard required for all Williams heater installations?
While specific requirements vary by local building codes, floorboards are highly recommended for any installation on combustible flooring to manage heat dissipation and unit stability.
Which specific Williams models does the 4163 fit?
This part is specifically sized for 50,000 BTU and 65,000 BTU units, including the 5001, 5002, 6501, and 6502 series. For smaller 20K or 35K BTU units, a different part number (typically the 4167) is required.
Does the floorboard include insulation?
Yes, the Williams 4163 is an insulated metal floorboard, meaning it features internal thermal damping to better protect the underlying floor surface compared to non-insulated alternatives.
