Venting System Assembly - Natural Vent
General Information
The Dutchwest Heater is shipped from the factory as
a Direct Vent Heater. It may be converted to a Natural
Vent heater by installing the Model Z31D00 FSDHAG
Draft Hood Adapter.
The Dutchwest Heater is approved for installation as
a Natural Vent. CFM Direct Vent pipe could be used
directly after the Draft Hood Adapter up to the ceiling,
then B-vent pipe must be used. Do not mix types of
B-vent pipe; use components from one maker or the
other. Follow the vent component maker’s instructions
exactly. The heater will also accept standard or enam-
elled 7” (150mm) diameter pipe, around the Type B
venting, for decorative purposes only. (Fig. 32)
NOTE: The restrictor plate supplied with the stove
is not used for Natural Vent applications.

The Dutchwest stove, when installed as a Natural vent
heater, includes a vent safety switch. (Fig. 60, Page
32) Operating the stove when it is not connected to a
properly installed and maintained venting system, or
tampering with or disconnecting the vent safety switch,
can result in carbon monoxide (CO) poisoning and pos-
sible death.
For U.S. installations: The venting system must con-
form with local codes and/or the current National Fuel
Gas Code, ANSI Z22.1.
For Canadian installations: The venting system must
conform to the current CSA B149.1 installation code.
Install the Vent Pipe
Apply a bead of sealant around bottom end of inner
starter pipe (found in bag with logset) and attach to
stove. Apply a bead of sealant around top of inner
starter pipe and install the Z31D00 FSDHAG Draft
Hood according to Draft Hood instructions. (Fig. 33)
