DV400S DIRECT VENT ROOM HEATER

To attach a straight section to the top of the Heater, with the female end down, slide that pipe over the outer Collar on the Heater while the Vent Inner slips into the Flue of the Heater.

MAINTAIN MINIMUM 1" CLEARANCES OR GREATER AROUND THE VENT SYSTEM.

Do not pack air spaces with insulation or other material.

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. (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.

Assemble the desired lengths of black pipe and elbows. It is necessary to reach from the Heater up through the round support box. Ensure that all pipe and elbow connections are in their fully twist lock position.

Using the mark from Step 2, drive a nail up through the roof to mark the center. Measure to either side of the nail and mark the opening required. This is measured on the horizontal; actual length may be larger depending on the pitch of the roof. Cut out and frame the opening. See chapter 25 of the Uniform Building Code

for Roof Framing details. A one inch minimum air space clearance must be maintained between the vent system and the roof.

Assemble lengths of pipe and elbows necessary to reach from the ceiling support box up through the roof line. Galvanized pipe and elbows may be utilized

in the attic, as well as above the roof line. The galvanized finish is desirable above the roof line due to its higher corrosion resistance.

4.Installing the Roof Flashing or Site-Produced Chase Top. Position a Roof Flashing (or construct a Chase and Chase Top) and secure in place with nails.

Continue to add Vent sections through the Roof Opening, maintaining at least 1” Air Space clearance. Major Building Codes specify a minimum Vent (Chimney) height above the Roof top depending on Roof Pitch. See Figure 10. Add Pipe sections

until the height of the Vent Cap meets the minimum Building Code requirements described in Figure 10. Note that for steep roof Pitches, the vent height must be increased.

These Vent System heights are necessary in the interest of safety, however, they do not ensure draft- free operation. Trees, buildings, adjoining Roof lines, adverse wind conditions, etc., may create a need for a taller Vent System should down drafting occur.

5.Termination Cap. Twist lock the Vent Cap.

WARNING!

THIS APPLIANCE MAY ONLY USE THE APPROVED VENTING SYSTEMS SHOWN IN THESE INSTALLATION INSTRUCTIONS. IT MUST NOT BE CONNECTED TO CHIMNEY FLUE SERVICING A SEPARATE SOLID FUEL OR GAS FUEL BURNING APPLIANCE.
