RULES FOR CONNECTOR PIPE INSTALLATION
1.The crimped end of the chimney connector fits inside the furnace flue collar. Install additional chimney connector and elbow with the CRIMPED END TOWARD THE FURNACE. This will allow any condensa- tion in the flue to run back into the furnace. Use 6" dia. (minimum 24 gauge) black chimney connector.
2.Slope anyhorizontalpipe upwardtowardthe chimney at least 1/4 inch for each foot of horizontal run.
3.You must have at least 18 inches of clearance between any horizontal piping and the ceiling. (See Fig. 3)
4.The chimney connector must not extend into the chimney flue (See Fig. 6).
5.Seal each chimney connector pipe joint with furnace cement. Also seal the pipe at the chimney.
6.Use 3 sheet metal screws at each chimney pipe joint to make the piping rigid.
7.The chimney connector may include a sec- tion for a barometric draft regulator between the furnace and the chimney (Fig. 4, 5, 6, & 7). The barometric draft regulator must be installed in the same room (same pressure zone) as the furnace.
8.Install the barometric draft regulator strictly in accordance with the instructions that are provided with the barometric draft regulator. A solid damper can be placed between the
9.barometric draft regulator and the chimney. (Fig. 4, 5, 6, & 7)
Adjusting the
Barometric Draft Regulator
1.Drill a hole in the chimney connector within 18" of the flue collar below the barometric draft regulator just large enough for the tube of the manometer.
2.Build a fire after all chimney connections have been made.
3.Use a manometer to measure the draft in the flue. (U.S. Stove Model
4.Adjust the barometric draft regulator to obtain a draft of 0.05" - 0.06" W.C. under stable conditions.
