Installation & Operation Manual

Prepare wall penetrations

1.Air pipe penetration:

a.Cut a hole for the air pipe. Size the air pipe hole as close as desired to the air pipe outside diameter.

Vent pipe penetration:

a.Cut a hole for the vent pipe. For either combustible or noncombustible construction, size the vent pipe hole per the vent manufacturer’s instructions.

2.Install the vent and air intake piping. Seal all gaps between the pipes and wall with RTV silicone sealant.

3.Seal all wall cavities.

Termination and fittings

1.The air termination must be oriented at least 12 inches above grade or snow line as shown in FIG. 4-1, page 21.

2.Maintain the required dimensions of the finished termination piping as shown in FIG. 4-1, page 21.

3.Do not extend exposed vent pipe outside of the building more than what is shown in this document. Condensate could freeze and block vent pipe.

4.Stainless steel terminations are designed to penetrate walls with a thickness up to 9.25 inches of standard construction.

Multiple vent/air terminations

1.When terminating multiple Crest boilers terminate each vent/air connection as described in this manual (FIG. 4-4).

￿WARNING All vent pipes and air inlets must terminate at the same height to avoid

possibility of severe personal injury, death, or substantial property damage.
