Field Controls 46234800 Motor Kit

The Field Controls 46234800 Motor Kit (Model SWG-4HDRMK) is the heavy-duty stainless steel replacement motor kit engineered for SWG series power venters, including the SWG-4HD, SWGII-4HD, and SWG-4HDS. This OEM assembly is a direct replacement for the legacy 46275900 part number, providing a drop-in solution for contractors servicing LP gas, natural gas, or oil-fired heating systems. Since power venting relies on mechanical draft, this 1/20 HP shaded pole motor is calibrated to provide 3,000 RPM at 115V AC (1.8 Amps), ensuring consistent flue gas extraction and maintaining 100% negative pressure within the vent pipe.

Built with technical durability in mind, the 46234800 features a corrosion-resistant 3.3 frame motor and a heavy-duty blower wheel pre-mounted on a 4-inch HD plate. The counter-clockwise (CCW) rotation effectively pulls combustion gases from the appliance, allowing for longer vent runs than traditional direct-vent configurations. By utilizing a high-performance induced draft setup, this kit permits the use of standard galvanized piping in many applications, eliminating the equipment cost of dedicated stainless steel venting while preventing flue gas leakage into the structure.

Key Benefits for HVAC Contractors:

• Direct OEM Compatibility: Serves as the precise replacement for 46275900 and SWG-4HDRMK, ensuring exact bolt-on alignment with 4" SWG housings.
• Industrial-Grade Construction: The stainless steel blower assembly is designed to withstand high-temperature flue gases and corrosive condensation in oil or gas applications.
• Complete Professional Kit: Includes the replacement motor, blower wheel on a mounting bracket, high-temperature silicone sealant, fasteners, and a hex wrench for field efficiency.
• Enhanced Safety: Engineered to maintain negative pressure, which prevents hazardous combustion byproducts from entering the mechanical room.

Common Questions & Troubleshooting:

• Is this compatible with older SWG-4HD units? Yes, the 46234800 is designed to upgrade both legacy and current SWG series 4-inch power venters.
• Does this include the blower wheel? Yes, this is a full fan and motor assembly, including the 46310400 blower wheel pre-installed on the bracket.
• What voltage is required for the SWG-4HDRMK? This is a standard 115V, 60Hz single-phase motor commonly used in residential and light commercial venting.
