VENTING
The Caddy Alterna is certified for use with a chimney certified to UL-103 or ULC S629M and a chimney type vent
certified to UL-641 or ULC-S-609-M89 and ULC/ORD C441-M90, with 4" inner diameter. In Canada, we recommend
that you use a listed pellet vent that meets the ULC S-609-M89 and ULC/ORD C441-M90 Standards. For the United
th
States, we recommend that you use a listed pellet vent that meets the UL-641, 7
edition Standard. This unit can be
vented in an existing chimney with the addition of a liner if the chimney is more than 4" in diameter. Class "A"
chimney is not required. Where passage through an attic of roof space, closet or similar concealed space, of a floor,
or ceiling, never use a chimney connector. Always use a chimney type vent or a chimney. Refer to the instructions
provided by the vent or chimney manufacturer, especially when passing through a wall, ceiling, or roof, and the
installation shall conform to CAN/CSA B365 and NFPA 211.
Your venting system should have at least one foot of vertical rise for each foot of horizontal run. The total
vertical rise on the outside wall should never be less than 3 feet (see Horizontal and Vertical Vent Chart).
This is a pressurized exhaust system. All vent connector joints must be sealed and fastened in accordance with the
pellet pipe manufacturer's instructions to ensure consistent performance and avoid smoke and ash spillage.
