The Williams 2102 blower kit is a field-installed accessory engineered to enhance thermal distribution for Williams vented hearth heaters. This heavy-duty automatic blower is the direct performance replacement for the P500250 and is compatible with 35,000, 50,000, and 65,000 BTU models, including relevant 350, 500, and 650 series units. Operating on a standard 120V AC circuit, this kit moves air at 150 CFM, effectively reducing heat stratification by forced convection. The assembly consists of a galvanized steel centrifugal blower, a pre-wired high/low/off speed switch, and a thermostatic fan switch that automates the cycle based on the heat exchanger temperature. For service technicians, this replacement blower assembly fits internally within the furnace casing, securing directly to the floor and inlet duct using factory-drilled mounting holes. It terminates in a three-prong grounding plug, simplifying the electrical integration. The Williams furnace fan kit is essential for larger floor plans where gravity-fed circulation is insufficient. By maintaining a 150 CFM airflow, it optimizes the output of 3501, 5001, and 6501 series heaters, ensuring the vented gas fireplace blower operates efficiently without interfering with the combustion air requirements of the unit. Key Benefits Direct OEM Substitute: Functional replacement for the legacy P500250 blower, ensuring a precise mechanical and electrical fit. Automated Operation: Internal thermo-disk fan switch engages the motor only when the furnace is at operating temperature to prevent cold drafts. Dual-Speed Control: Includes a factory-wired toggle allowing the contractor or end-user to select between high and low performance settings. Heavy-Duty Construction: Built with galvanized steel and UL-standard components for long-term reliability in high-heat environments. Improved Heat Cycle: Increases the BTU distribution efficiency, forcing heated air into the living space rather than allowing it to rise and trap at the ceiling. Common Questions Is the 2102 blower compatible with all Williams heaters? This kit is specifically designed for vented hearth heaters (35K, 50K, and 65K BTU). It is not for use with 2001622A or 2001621A models. Use it as a direct upgrade for the Williams 2102 blower kit or replacement for the P500250. Does this blower require a dedicated electrical circuit? The unit runs on 120V and draws approximately 1.5 to 3.6 amps depending on the specific motor iteration. It includes a standard three-prong plug for a grounded outlet, so a dedicated hardwired circuit is typically not required, though code-compliant grounding is mandatory. Will the furnace still work if there is a power outage? Yes, the vented hearth heater will continue to provide gravity-fed heat without power. However, the 150 CFM forced-air circulation provided by the blower will be disabled until power is restored. This item is not eligible for free shipping.
