Combined Air Inlet Points

The air inlet pipes from multiple appliances installed with an Intelli-Vent system can be combined to a single common connection based on the cross sectional area of the common pipe as defined in the Direct Vent basic information section.

Maximum Length of an Intelli-Vent System

The maximum installed length of the air inlet pipe from the appliance to the air inlet cap is 100 equivalent feet (30.5 m) in length. The maximum installed length of the flue pipe from the appliance to the termination cap is 100 equivalent feet (30.5 m) in length. Subtract 5 feet (1.52 m) of equivalent length for each 90° elbow installed in either the flue pipe or the air inlet pipe.

Subtract 2 1/2 feet (0.7 m) of equivalent length for each 45° elbow installed in either the flue pipe or the air inlet pipe.

VERTICAL INTELLI-VENT WITH SIDEWALL COMBUSTION AIR

FIG. 27 Vertical Intelli-Vent Installation - Sidewall Combustion Air Inlet

Intelli-Vent systems are installed with a Category IV flue and a separate combustion air pipe to the outdoors. The Vertical Intelli-Vent system terminates the flue at the rooftop and air inlet at the sidewall. The flue outlet and combustion air intake terminates in different pressure zones.

Follow all requirements in the General Category IV Venting sections for proper installation and venting of flue products vertically to the outdoors. All other general installation requirements must be followed.

The Intelli-Vent system requires the installation of an additional pipe to supply combustion air from outdoors directly to the appliance.

Termination point for the flue products must follow the clearance requirements in the Vertical Vent Termination section of the Category IV Venting.

CAUTION￿

Appliances that are shut down or will not operate may experience freezing due to convective airflow in the air inlet pipe connected to the appliance.

SIDEWALL COMBUSTION

AIR INLET

FIG. 28 Air Inlet Cap for Sidewall Termination

The air inlet cap for the sidewall air inlet must be purchased from the appliance manufacturer.

The part numbers for the required sidewall air inlet cap kit are listed by unit size. The appliance manufacturer, in accordance with CSA requirements, must furnish the sidewall air inlet cap. Each kit includes the special combustion air inlet cap for installation on an exterior sidewall.
