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 another. Follow the vent component
maker’s instructions exactly. The heater will also accept
standard or enamelled 7” (150 mm) diameter pipe,
aroudn 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 Jefferson stove, when installed as a Natural vent
heater, includes a vent safety switch. (Page 32, Fig. 63)
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
possible death.
For U.S. installations: The venting system must
conform 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 Z31B00 FSDHAG Draft
Hood according to Draft Hood instructions. (Fig. 33)
Attach the first section of venting to the draft hood.
Depending on the length of the individual venting
sections and the lengths of the decorative pipe (if
installed), you may need to slip the decorative pipe over
the venting sections before attaching upper sections
to lower ones. The sections of decorative pipe should
be oriented with their seams (if any) toward the wall;

joint, other than slip sections. If the layout includes
a slip section, this should be the last section of pipe
