Vent Adapter (17735 & 29035 Series)

The Vent Adapter Accessory is used to compensate for the extra space left around the vent hole when replacing a furnace with a larger vent opening. It can also be used to extend the flue terminal on homes with vinyl siding so that the vent cap lies flush against the edge of the siding.

Air necessary for combustion is drawn into the chamber from outside through direct wall vent, and all combustion products are vented directly to the outside. Only clean, gentle heat, in continuous circulation is delivered into the room. Windows and doors can stay closed because no room air is used for combustion.
