MARS Concentric Vent Kits provide a single wall or roof penetration solution for high-efficiency gas furnaces or condensing tankless water heaters. Concentric vents save time and money by streamlining installation compared to the traditional 2 pipe system. Concentric vents also improve the aesthetics of the home by reducing the number of wall and roof penetrations. All necessary fittings are included in the kit. (The installing contractor needs to supply pipe and fittings between the furnace/tankless water heater and concentric vent.)
