surface of the burner. Note this dimension here

________.

2.Using the tape measure, transfer this measure- ment to the inside surface of the exterior wall that the vent will penetrate; make a reference mark. Check the location of the hole to ensure that there are no internal wall structures (i.e. studs) to pre- vent penetration. Also check that the outlet of the vent does not compromise the general venting requirements, See Section 5.1.

3.Using a tape measure, measure distances ‘A’, ‘B’, ‘C’ and ‘D’ as shown in Figure 18. Note these dimensions here (A= ______, B= ______, C=______, D=______) and add them together.

NOTE: If the total of dimensions above are greater than 5' (1524 mm), a 5’ (1524 mm) balanced flue vent extension kit (P/N 08039000) will be required.

4.From the reference mark made in step 2, measure down vertically 1/4" (6 mm) per foot measured in step 3. Cut 5” (125 mm) vent terminal clearance hole at the lower reference.

5.Cut the 3” (80 mm) vent to length as follows: Length A

3” diameter = A – 8”

Length B

3” diameter = B + C + D – 7 3/4”

Always cut a non-swaged end.

6.Wrap the 1" (2.5 cm) diameter spring around the outside diameter of the 3" (80 mm) elbow as shown in Figure 19.

7.Interlock the loops at each end of the spring coils together as shown in Figure 19. The loops will lock together to produce a continuous coil spring spacer around the outside diameter of the 3" (80 mm) elbow.

8.Fit the 5" (125 mm) elbow over the 3" (80 mm) elbow (Figure 20).
