When penetrating an outside wall the air intake and vent pipes must be constrained as shown in Figure 6. The openings through which the air intake and vent pipes pass must be properly sealed to prevent products of combustion from entering the building.

WARNING: Failure to properly install and seal the air intake and vent system can result in excessive levels of carbon monoxide which can cause severe personal injury or death!

Figure 6 - Wall Penetration Detail

In some cases it may be necessary to attach the air intake and vent pipes to the outside wall for added rigidity, Figure 7. If this is the case, special bracket GT-82075 must be ordered for each pipe. Proper clearances must be maintained.

Figure 7 - Air Intake & Vent Pipe Attachment

For installations that have to exit the foundation below grade excavate the site as shown in Figure 8 to a point below where the pipes exit the building. Maintain the proper vent clearances as outlined above. Attach the vent and air intake pipes to the outside of the building using special bracket 82075. Ensure that the wall penetrations are properly sealed before backfilling the site.

Figure 8 - Below Grade Installation

If required, the air intake and vent systems may be run along an outside wall, Figure 9, providing the following conditions are met:

1.The maximum length on the outside of the building is not more than 20 ft, 6.1 m.

2.All normal termination clearances are maintained.

3.The entire vent system external to the building is insulated using closed cell foamed polyolefin tubing having a minimum wall thickness of 1/2 in, 13 mm.

4.The air intake and vent systems are supported every 24 in, 610 mm.

5.The air intake and vent systems are sloped 1/4 in/ft, 21mm/m back toward the boiler.
