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;
