DV400S DIRECT VENT ROOM HEATER

The Dura-Vent GS is unitized and twist-locks together. For the twist-lock procedure, consult Figure 5 and do the following:

(1)Four indentations, located on the female ends of pipes and fittings, are designed to slide straight onto the male ends of adjacent pipes and fittings, by orienting the four pipe indentations so they match and slide into the four entry slots on the male ends. See Figure 5. Push the pipe sections completely together, then twist-lock one section clockwise approximately one-quarter turn, until the two sections are fully locked. The female locking lugs will not be visible from the outside, on the Black Pipe or fittings. They may be located by examining the inside of the female ends.

(2)Horizontal runs of vent must be supported every three feet. Wall Straps are available for this purpose.

Before connecting the horizontal run of vent pipe to the vent termination, slide the black decorative wall thimble cover over the vent pipe.

When using the adjustable section, maintain a 1” overlap on pipe sections and secure. It is also important that the vent pipe extends a minimum of 1 1/2” into vent cap.

3.Termination Cap. Position the horizontal vent termination so that 1 1/2” clearance is maintained on top of the vent sections and 1 1/2” on sides.

Before attaching the Vent Termination to the exterior wall, run a bead of non-hardening mastic around the outside edges to make a seal between the Cap and the wall.

Attach Cap to exterior wall with four (4) wood screws, making sure that arrow on Cap is pointing up. After Cap is attached, make sure that a 1 1/2” is maintained from top of vent to combustibles.

Secure the connection between the vent pipe and the vent cap by attaching the two sheet metal strips extending from the vent cap assembly into the outer wall of the vent pipe. Use the two sheet metal screws provided to connect the strips to the pipe section. Bend any remaining portion of the sheet metal strip back towards the vent cap, so it will be concealed by the decorative wall thimble cover. See Fig.6.

Slide the Decorative Wall Thimble up the wall surface and attach with the screws provided. Apply Decorative Brass or Chrome Trim if desired. See Fig. 7.

4.Vertical Rise on the Exterior. For installations requiring a vertical rise on the exterior of a building, 14” and 36” tall Snorkel Terminations are available. Follow the same installation procedures that are used for the standard horizontal termination found in Step 3.
