Draft Control Installation

See Figure 4 for typical vent system layout.

CAUTION: This draft control is shipped as a single acting draft control. If the draft control is not being used on a gas draft induced furnace, remove the gate stop on the draft control ring before installing.

COLLAR INSTALLATION

This control is shipped with a collar patterned to fit a single wall round vent pipe. To attach this collar to the flue, see Figure 5 and follow the instructions below.

1.Bend outward the two ears at the front corners of the collar. Bend 90 degrees, 1/4 inch behind the single hole on the

straps.

2. Insert clamping screw in ears on collar and bolt the remainder of the collar together.

3. Hold the collar against the side of the flue in the exact position it is to be installed (shown by dotted lines) and mark the outline of the collar on the flue.

4.Cut a hole in the flue about 1/2" inside of this outline.

5.Make a series of cuts about 1/2" apart from the edge of this hole to the outline marks.

6.Strap the collar to the flue pipe.
