The Dutchwest Natural Vent stove will accept decora- tive 6” (150mm) stove pipe around the Type B venting system, for aesthetic purposes.
Complete Type B vent systems are available from a number of manufacturers, and your dealer can usually supply one. Pipe sections from different makers are not interchangeable; do not mix pipe or vent sections from different makers. Follow the vent system manufacturer’s instructions.
The vent system should conform to the specifications of the National Fuel Gas Code, latest edition.
If connecting to a Class A chimney system, use 4” (100mm) single wall or 4” Type B vent connector. Single wall vent connector requires a minimum 6” (150mm) clearance to combustible surfaces.
Exterior chimneys may be subject to flow reversal or condensation. To lessen these conditions, enclose Type B vents in an insulated chase, or reline exterior Class A chimneys.
An approved
Venting terminals shall not be recessed into a wall or siding.
Vent Layout and Height Requirements
Venting for a Dutchwest can rise vertically through the home, or can pass through an exterior wall and rise along the outside of the home. Some codes require that a Type B vent system rising on the outside of the home be enclosed in a chase. Check your local codes for requirements.
The minimum vent system height for the Dutchwest Natural Vent Stove is 8’ (2.43m), (Fig. 7) measured from the top of the stove. To determine the minimum height the vent system must extend through or past the roof, refer to the 1993 edition of the National Fuel Gas Code.
