FIG. 25 Air Inlet Cap for Sidewall Termination

The sidewall combustion air inlet cap MUST NOT be installed above the sidewall flue outlet if it is located within a 10 foot (3.05 m) radius of the flue outlet.

The sidewall combustion air inlet cap must not be installed closer than 10 feet (3.05 m) from an inside corner of an L-shaped structure.

The sidewall combustion air cap assembly used MUST adequately protect the combustion air inlet from wind and weather.

The sidewall combustion air inlet cap and flue gas outlet MUST be located on the same sidewall surface and in the same pressure zone.

Combustion air supplied from outdoors must be free of contaminants (see Combustion and Ventilation Air). To prevent recirculation of flue products into the combustion air inlet, follow all instructions in this section.

FIG. 26 Multiple Horizontal Direct Vent Caps Installed on a Sidewall

The combustion air inlet caps for multiple appliance installations must maintain the same minimum clearance from the closest vent cap installed within a 10 foot (3.05 m) radius of the point of flue gas termination as specified in single appliance installations. Multiple flue outlet caps may be installed side by side and multiple air inlet caps may be installed side by side but the minimum clearance of 3 feet (0.91 m) horizontal radius and 12 inches (0.30 m) below the closest flue outlet to the air inlet cap must be maintained. All clearance and installation requirements in this section and the applicable portions of the general Category IV venting section must be maintained on multiple appliance installations.

INTELLI-VENT SYSTEMS

An Intelli-Vent system is a Category IV flue installed with a separate combustion air pipe to the outdoors. The Intelli-Vent system terminates the flue and the combustion air inlet pipe in different pressure zones. The Intelli-Vent system may terminate the flue and combustion air in any one of three configurations.

These are:

(1)

The

flue

on

the

roof

top

and

combustion

air intake

 

on the sidewall;

 

 

 

 

 

 

(2)

The

flue

on

the

sidewall

and

combustion

air

from

 

the rooftop;

 

 

 

 

 

 

 

(3)

the

sidewall and the combustion air on

 

a sidewall other

than

the

sidewall where

the

flue

 

is located.

 

 

 

 

 

 

 

 

All appliances are shipped from the factory equipped for Category IV venting system. The optional Intelli-Vent systems require the installation of specific venting materials that are purchased locally. Sidewall termination caps for flue products and combustion air must be purchased from the manufacturer. The sidewall caps for combustion air and flue products are available as vent kits. The following is a detailed explanation of the installation requirements for each venting system, components used and part numbers of vent kits for each model.

Follow all requirements in the General Category IV Venting sections for proper installation and of venting flue products to the outdoors with either a rooftop or a sidewall termination. 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. The air inlet pipe must use one of the specified materials.
