4.Tighten the upper gear clamp to ensure the vent pipe is firmly secured and gas tight.

5.Check that the lower gear clamp is firmly seated, secured and gas tight.

6.As a final check, the vent pipe should be gently moved side to side and vertically. There should be no slippage or movement of the vent pipe within the coupling.

7.Seal around the termination assembly where it passes through the wall, inside and out, with silicone sealant.

Notes:

1. Each 50mm (2 in.), 90° long radius elbow is equivalent to 1.5m (5 ft.) of vent length.

2. Each 76mm (3 in.), 90° long radius elbow is equivalent to 2.1m (7 ft.) of vent length.

3. Each 50mm (2 in.), 45° long-radius elbow is equivalent to 0.9m (3 ft.) of vent length.

4. Each 76mm (3 in.), 45° long radius elbow is equivalent to 1.2m (4 ft.) of vent length.

5. Minimum distance between elbows is 150mm (6 in.).

6. Do not mismatch venting materials. *Check local codes to determine which materials are allowed in your area.

7. **Pipe assembly adaptor must be used with PVC venting material (see Figure 14). Table 2 Allowable Vent Lengths and Materials (Vert. and Horiz.).
