Rules for Connector Pipe Installation
1.The crimped end of the chimney con- nector fits inside the furnace flue collar. Install additional chimney connector and elbow with the CRIMPED END TOWARD THE FURNACE. This will allow any con- densation in the flue to run back into the furnace. Use 6" dia. (minimum 24 gauge) black chimney connector.
2.Slope any horizontal pipe upward toward the 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 chim- ney pipe joint to make the piping rigid.
7.The chimney connector may include a section 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 fur- nace.
8.Install the barometric draft regulator strictly in accordance with the instruc- tions that are provided with the baromet- ric draft regulator.
9.A solid damper can be placed between the 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 connec- tions 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.
