Tagaki T-KD20 uses a “Direct Vent System”. With a three-inch round combustible air intake vent and four-inch round exhaust power vent, Flash T-KD20 is designed to work when indoor combustion air is not available – making it the perfect system for climate controlled environments such as colder areas. This system is called a “sealed combustion” system and is required in Minnesota.
