Dutchwest Direct Vent / Natural Vent Gas Heater
For DuraVent pipe only: Install vent pipe by align- ing the locking system together, sliding the pipes together and twisting clockwise.
•Install 90° elbow. Twist lock as before.
•Slide the wall plate over horizontal run before at- taching the horizontal run to the elbow. Fasten wall plate to wall.
4.For CFM Vent Pipe only: If necessary, measure to determine the vertical length (X) of pipe required from the adapter pipe to the wall cutout centerline, including a 2” (51mm) overlap at the joint. (Fig.
24) use a hacksaw or tin snips to trim the pipe as needed.

5.Install first the inner then the outer straight pipe section(s), trimmed end down, to the point of the el- bow. Drill 3 holes through each joint and fasten with sheet metal screws.
6.Seal and install the elbow using 3 sheet metal screws at each joint.
7.Measure, and cut if needed, the appropriate length of pipe section needed to make the connection through the wall. Include a 2” overlap; i.e. from the elbow to the outside wall face, about 2” or the dis- tance required if installing a second 90° elbow. (Fig. 25)
8.Slip the wall plate and trim collar over the interior end of the horizontal pipe and install into the wall sleeve. Seal the joint inside the wall plate if needed to keep cold air from being drawn into the home.
9.Seal the ends and connect the horizontal pipe to the elbow. Fasten the wall plate to the pipe with three sheet metal screws. Slide the trim collar up against the wall plate to cover the screws. (Fig. 26)

10.For both CFM and DuraVent Systems: Install the vent terminal. (Fig. 27) Apply high temperature seal- ant one inch from the ends of the inner and outer collars. Guide the inner and outer vent termination collars into the adjacent pipes. Double check that the vent pipes overlap the collars by 2”. Fasten the termination to the wall with the screws provided, and caulk the joint with weatherproof sealant.
11.For CFM only: Install Charcoal Gray Pipe Rings (#7FSDRG) or Polished Brass Pipe Rings (#7FS- DRP) at pipe joints, if desired.
