Lochinvar 000, 1 Sidewall Combustion AIR Inlet, Table G, Location of a Sidewall Air Inlet Cap

Page 17

The Direct 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.

The maximum installed length of the air inlet pipe from the appliance to the air inlet cap is 100 equivalent feet (30.48 m) in length. The maximum installed length of the flue pipe from the appliance to the termination cap is 100 equivalent feet (30.48 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 or the air inlet pipe.

Termination point for the flue products must follow the clearance requirements in the Sidewall Venting Termination sections of the Category IV Venting.

FIG. 23 Horizontal Direct Vent Installations with Sidewall Combustion Air Inlet

SIDEWALL COMBUSTION

AIR INLET

Horizontal Direct Vent systems installed with sidewall terminations for both combustion air and flue products must purchase the termination caps from the appliance manufacturer. The sidewall air inlet cap and sidewall vent cap for flue products are available as a vent kit.

FIG. 24 Sidewall Vent Cap

The part numbers for the required sidewall air inlet cap kit are listed by unit size. The 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. The sidewall air inlet cap supplied in the kit is sized to provide combustion air for a single appliance only.

*Piping from the appliance to the air inlet cap may be either 7" or 8" connecting to an 8" sidewall cap provided in the kit.

Location of a Sidewall Air Inlet Cap

Incorrect installation and/or location of the air inlet cap can allow the discharge of flue products to be drawn into the combustion process on the heater. This can result in incomplete combustion and potentially hazardous levels of carbon monoxide in the flue products. This will cause operational problems with the heater and possible spillage of flue products that can cause personal injury, death or property damage.

The termination point of the sidewall air inlet must be installed a minimum of 12 inches (0.30 m) above ground level and above normal levels of snow accumulation.

The point of termination for the sidewall combustion air inlet cap MUST be located a minimum of 3 feet (0.92 m) horizontally and 12 inches (0.30 m) below the point of flue gas termination (vent cap) if it is located within a 10 foot (3.05 m) radius of the flue outlet.
