Termination and fittings

4 Sidewall direct venting

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

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

3.If using the alternate sidewall termination 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.PVC/CPVC terminations are designed to accommodate any wall thickness of standard constructions per the directions found in this manual.

5.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 Knight boilers terminate each vent/air connection as described in this manual (FIG. 4-5A).

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.

2.Place wall penetrations to obtain minimum clearance of 12 inches between edge of air inlet and adjacent vent outlet, as shown in FIG. 4-5A for U.S. installations. For Canadian installations, provide clearances required by CSA B149.1 Installation Code.

3.The air inlet of a Knight boiler is part of a direct vent connection. It is not classified as a forced air intake with regard to spacing from adjacent boiler vents.
