The Maximum length of 4-inch diameter rigid metal duct that can be run for the Energy Star® Qualified LG 4.5 Cu. Ft. HE Smart Front Load Washer and 7.4 Cu. Ft. Electric Dryer WashTower™ with Steam and Built-In Intelligence - White, Model # WKE100HWA, without any 90° elbows is 65 ft. (19.8 m), when using a 4 ‘’ (10 cm) wall cap. According to standard building codes (IRC Section M1502), the maximum length for a 4-inch diameter rigid metal dryer duct is typically 35 feet (10.7 meters), so the LG recommendations supersede general code, allowing for longer runs of up to 65 Ft. However, you generally cannot exceed the manufacturer's recommended maximum duct length without modifying the system, as doing so violates most local building codes and creates significant safety risks. Building codes such as the International Residential Code (IRC) and International Mechanical Code (IMC) strictly regulate dryer ducting to prevent house fires caused by lint accumulation. If your specific dryer manufacturer provides installation instructions that allow for a longer run, like LG's instructions for this dryer, the building code typically defers to those instructions. If the run must be longer than the dryer can handle, you can install a dryer exhaust duct power ventilator (booster fan). These fans help maintain airflow over long distances (up to 100–150 feet) and must be installed according to the fan's specific instructions...^Ivan.
