Manufacturer replacement parts for boilers, water heaters and heating appliances: ignition assemblies, gas valves, blowers and fan assemblies, switches and sensors, conversion kits and control boards.
These are appliance-specific. A gas valve or ignition assembly is matched to the model and often to the serial range within that model, because manufacturers revise components mid-production without changing the appliance name. Order from the data plate — model and serial — not from the appliance description.
Fuel conversion kits deserve particular care. A natural gas to propane conversion changes orifice size and regulator spring, and it is only legal when the manufacturer lists that specific kit for that specific appliance; a generic kit or a field-drilled orifice voids the listing and the warranty.
Brands include IBC, US Boiler, Rheem and Navien.
