WARNING: Improper installation, adjustment,
alteration, service or maintenance can cause
injury or property damage. Refer to this manual
for correct installation and operational procedures. For assistance or additional information
consult a qualified installer, service agency, or
the gas supplier.
Venting Requirements and Options
The Dutchwest must be properly connected to a listed
4” (100mm) 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
systems is required.
The Dutchwest Natural Vent stove will accept decorative 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 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’ (2.43m), (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.

30002008
Dutchwest Natural Vent Gas Heater
Passing Through a
Combustible Wall or Ceiling
An approved pass-through device is always required
when a vent passes through a combustible wall or
ceiling. Check with the maker of the vent system for
the correct listed devices that are available. A listed
pass-through device is required whether or not the
installation includes decorative pipe around the Type B
venting system. NOTE: It is essential to seal between
the ceiling support (sometimes called a ‘firestop
spacer’) and the decorative pipe, if installed, with a
high-temperature silicone sealant. (Fig. 6)

Install the Optional Fan
1. The fan kit includes a blower assembly and a
rheostat assembly, connected by a cable. The
blower assembly mounts to the bottom rear of the
stove, and the rheostat mounts to the left side of the
valve. The assembly includes a ‘snapstat’ which
automatically turns the fan ON (or OFF) above (or
below) approximately 109°F. The rheostat also
provides a range of fan speed settings from Off
(which overrides the snapstat function) to High.
Unpack and inspect the blower assembly. Confirm
that the fan spins freely.
2. Attach the fan assembly to the bracket provided in
the log box. Use #10 sheet metal screws provided
with fan kit. Do not remove finger guard screws.

that bracket.
• Attach the control knob to the rheostat shaft.
• Use the wire tie to secure the fan and rheostat
wire harnesses together.
10.Plug the power cord into a standard grounded 110
volt household outlet. If the fan control knob is not
turned to the OFF position, the fan will turn on when
the temperature at the snapstat reaches
approximately 109°F.
Venting System Assembly
The venting collar is on the sheet metal draft hood/heat
exchanger assembly, over the firebox. Use a B-vent
adapter, from the same maker as the rest of the B-vent
components, to join the first section of venting to the
draft hood.
The stove includes a spill switch. Operating this stove
when not connected to a properly installed and maintained venting system, or tampering with or disconnecting the spill switch, can result in carbon monoxide (CO)
poisoning and possible death.
The stove includes a bracket for installing decorative 6”
(150mm) round stove pipe around the B-vent, for
appearance purposes only. The decorative pipe need
not be concentric with the vent pipe.
If the installation includes decorative stove pipe around
the venting system, make a cardboard template of the
decorative pipe by tracing its circumference. Put this
template in the flue recess in the stove top. Position
the template to fit well against the front of the recess.
(Fig. 16) Use this template to locate the bracket to hold
the decorative pipe. Depending on spacing, the bracket
may fit inside the decorative pipe without interfering
with the vent system. Fasten the bracket to the draft
hood/heat exchanger assembly with a sheet metal
screw.
