Description
The Pentair 461031 Direct Air Intake Duct Kit provides indoor MasterTemp pool heater installations with a dedicated pathway for drawing clean outside combustion air through a 3-inch PVC duct routed vertically or horizontally to suit your equipment room layout. Shipped as a complete OEM package, the kit contains a heater panel cut-out, air orifice adapter, a section of 3″ PVC pipe, a union fitting, and a screened termination cap engineered to block insects, rodents, and airborne debris from reaching the burner. By channeling fresh exterior air directly to the combustion chamber instead of drawing from potentially humid or chemically saturated indoor air, this duct kit optimizes burner performance, helps satisfy local ventilation code requirements, and extends the operational life of your MasterTemp heater.
