1998-2006 Edition
A conventional direct vent system must be constructed from a 3" (76mm) diameter listed "PL" type pipe and
1-5/8" (41mm) diameter rigid or flexible hose or pipe. The 3" (76mm) diameter "L" type pipe transports the
exhaust gases while the 1-5/8" (41mm) diameter hose or pipe transports combustion air from the outside of
the home to the stove. This type of vent system is easy to install and maintain. However, two holes must be
cut in the exterior wall for this system to pass through. All components required for this vent system are
available at all local hardware stores and at the local Jamestown Dealer.
It is necessary to cut a 7" (178mm) and a 1-3/4" (45mm) diameter hole in the wall as passages for the vent pipe and the air
intake tube.
1. Determine the location of the 7" (178mm) diameter hole by referring to the section labeled "J3020A kit Installation
Instructions" in this manual. Mark the hole location.
2. Determine the location of the 1-3/4" (45mm) hole. Determine this location based on the tube material that you are
using. Remember that the openings in the exhaust vent cap must be a minimum of 12" (305mm) from the openings
in the air intake rodent screen openings.
3. Cut the 7" and the 1-3/4" (178mm and 45mm) holes in the wall using an appropriate saw.
4. Move the stove away from the wall to provide enough clearance for the entire length of the exhaust pipe.
