RULES FOR CONNECTOR PIPE INSTALLATION

SERVICE HINTS

1.The crimped end of the stovepipe fits inside the heater flue collar. Install ad- ditional pipe and elbow with the

CRIMPED END TOWARD THE HEATER. This will allow any condensation in the flue to run back into the heater. Smoke will not escape when installed in this manner.

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 pip- ing and the ceiling.

4.The pipe cannot extend into the chimney flue. (Fig. 8)

5.Seal each connector pipe joint with furnace cement. Also seal the pipe at the chimney.

6.Use 3 Sheet Metal screws at each joint to make the piping rigid.

7.It is recommended that no more than two 90 degree bends be used in the stovepipe installation as more than two may decrease the amount of draw and possible, use only corrugated (nonad- justable) elbows. They are much more airtight.

8.The chimney connector must not pass through an attic or roof space, closet, or any concealed space, or floor, ceiling, wall or combustive construc- tion.
