Alterna II to use the same hot air ducts is not allowed.
5.7 VENTING SYSTEM
5.7.1 GENERAL
Even though the chimney draft is mechanical, a suitable venting system will ensure a natural draft which will
prevent smoke spillage in your home if a power outage occurs. Moreover, a suitable venting system
configuration will help get the best efficiency out of your furnace when installed in accordance with the required
EVL (see
Section 5.7.4: Equivalent Vent Length (EVL) ).
Even the best furnace will not function safely and efficiently as intended if it is not connected to a suitable
venting system.
5.7.2 STANDARDS
The Caddy Alterna II is certified for use with a chimney certified to UL 103 or ULC S629M and a chimney type
vent certified to UL 641 or CAN/ULC-S-609 and ULC/ORD C441
, with 4” inner diameter. In Canada, we
recommend that you use a listed pellet vent that meets the CAN/ULC S-609 and ULC/ORD C441 Standards.
For the United States, we recommend that you use a listed pellet vent that meets the UL 641. 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 CSA B365 IN Canada or NFPA 211 in the United States.
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
Section 5.7.5 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.
