Connectors shall be used to connect fuel-burning appliances to a vertical chimney or vent except where the chimney or vent is attached directly to the appliance.

Vent and chimney connectors shall be installed in accordance with the manufacturer's instructions and within the space where the appliance is located.

Appliances shall be located as close as practical to the vent or chimney. Connectors shall be securely supported and joints shall be fastened with sheet metal screws or rivets. Devices that obstruct the flow of flue gases shall not be installed in a connector unless listed and labeled or approved for such installation. Connectors for oil-fired appliances listed and labeled for Type L vents , passing through walls or partitions shall be in accordance with the following: Type L vent material for oil appliances shall be installed with not less than listed and labeled clearances to combustible material.

Single-wall metal pipe shall be guarded by a ventilated metal thimble not less than 4 inches mm larger in diameter than the vent connector. Not less than 6 inches mm of clearance shall be maintained between the thimble and combustibles. The horizontal run of an uninsulated connector to a natural draft chimney shall not exceed 75 percent of the height of the vertical portion of the chimney above the connector. See Figure 2. Safety concerns are of primary importance with any heating system and should be with direct vented applications.

As previously stated, air flow proving switches are typically used to ensure proper draft from the induced draft fan. Temperature sensing switches can be utilized as back-up protection for a blocked vent condition.

Through-the-wall fittings must be designed for walls constructed of combustible materials. Reliable operation is a second concern. Wind direction and velocity can have a great impact on a side wall exhaust vent and must be considered both in system design and in installation. A closed air system with outside intake on the same wall as the exhaust vent will tend to reduce this problem.
