Lochinvar 000 Construction Air Filter Kits Table - C, Venting, Input, Btu/hr, Vent System Options

The construction air filter MUST be removed from the appliance’s air inlet before the appliance is placed in normal operation. Once the construction air filter is removed, ensure that either the equipment room is supplied with combustion air from properly sized combustion and ventilation air openings or a combustion air duct from a Direct Vent or Intelli-Ventsystem is connected to the appliance. The optional Direct Vent and Intelli-Ventventing systems have specific requirements for a special combustion air duct from the outside that is directly connected to the appliance. See the requirements for this combustion air duct in the venting section for each specialized vent system.

VENTING

Vent System Options

This appliance has three venting system options. They are: (A) Category IV Venting system with vertical roof top termination or sidewall termination of the flue and combustion air supplied from the mechanical room. (B) Direct Vent with a Category IV flue and a separate combustion air pipe to the outdoors. The Direct Vent system terminates both the flue and air inlet in the same pressure zone. The flue outlet and combustion air intake may terminate on either the sidewall or with a rooftop termination.

(C)Intelli-Ventwith a Category IV flue and 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 on the roof top and combustion air intake on the sidewall, the flue on the sidewall and combustion air from the rooftop or the flue on the sidewall and combustion air from a different sidewall. All appliances are shipped from the factory equipped for Category IV venting. The optional Direct Vent and Intelli-Ventventing systems will require the installation of specific vent kits and venting materials. 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.

General

Vent installations for connection to gas vents or chimneys must be in accordance with Part 7, “Venting of Equipment,” of the latest edition of the National Fuel Gas Code, ANSI Z223.1, in Canada, the latest edition of CAN/CGA Standard B149 Installation Codes for Gas Burning Appliances and Equipment or applicable provisions of the local building codes.

Adequate combustion and ventilation air must be supplied to the equipment room in accordance with the latest edition of the National Fuel Gas Code, ANSI Z223.1, in Canada, the latest edition of CAN/CGA Standard B149 Installation Codes for Gas Burning Appliances and Equipment, or applicable provisions of the local building codes.

The distance of the vent terminal from adjacent buildings, windows that open and building openings MUST comply with the latest edition of the National Fuel Gas Code, ANSI Z223.1, in Canada, the latest edition of CAN/CGA Standard B149 Installation Code for Gas Burning Appliances and Equipment.

Vent connection is made directly to the flue outlet opening on the back of the unit. The connection from the appliance vent to the stack must be made as direct as possible.

IMPORTANT

Examine the venting system at least once a year. Check all joints and vent pipe connections for tightness. Also, check for corrosion or deterioration. Immediately correct any prob- lems observed in the venting system.
