4 Venting system

4.1 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 getting the best efficiency out of your stove
when installed in accordance with the required EVL (see Section 4.3 Equivalent Vent
Length (EVL)).
Even the best stove will not function safely and efficiently as intended if it is not connected to
a suitable venting system.

4.2 Recommendations

In Canada, we recommend that you use a listed pellet vent that meets the CAN/ULC S609 or
ULC/ORD C441 Standard. A pellet vent listed to ULC S629M is also suitable for installation
with this stove.
For the United States, we recommend that you use a listed pellet vent that meets the UL 641
Standard. A pellet vent listed to UL 103 is also suitable for installation with this stove.
This stove can be vented in an existing factory-built or masonry chimney with the addition of a
stainless steel liner, provided the chimney is more than 4" in diameter. The liner should be
listed and should meet the ULC S635 CAN/ULC S640 standard in Canada and the UL 1777
standard in the USA. Refer to the instructions provided by the vent manufacturer, especially
when passing through a wall, ceiling or roof.
