Dutchwest Natural Vent Gas Heater
30002008
Venting Requirements and Options
The Dutchwest must be properly connected to a listed
4” (102 mm) Type B venting system or to an approved
Class A masonry or factory-built chimney system. In
Canada, a complete relining of Class A chimney sys-
tems is required.
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 manufactur-
er’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” (102
mm) single wall or 4” Type B vent connector. Single wall
vent connector requires a minimum 6” (152 mm) clear-
ance 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 pass-through device is always required,
whether the vent system passes through a wall or
a ceiling. Use a pass-through device from the same
maker who supplies the venting system.
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’ (2.43 m), (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.
