Venting System Assembly - Natural Vent

General Information

The Jefferson Heater is shipped from the factory as a Direct Vent Heater. It may be converted to a Natural Vent heater by installing the Vermont Castings Model Z31D00 FSDHAG Draft Hood Adapter.

The Jefferson 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 makerÕs instructions exactly. The heater will also accept standard or enamelled 7Ó (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 Jefferson stove, when installed as a Natural vent heater, includes a vent safety switch. (Fig. 64, Page 33)

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 Z31D00 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; sections usually do not need to be fastened at each joint, other than slip sections. If the layout includes a slip section, this should be the last section of pipe visible in the room, at the ceiling. Complete the venting according to the vent makerÕs instructions.
