1.2 Venting Requirements

The flue is a critical component to a satisfactory installation. Your Osburn insert will attain its best

performance if installed with a chimney that generates its own draft. The minimum requirement of a flue

will be the installation of a flue connector (the liner must conform to UL1777 chimney liners) from the

insert into the first flue tile of the chimney (USA), see Figure 2.6a, or a continuous stainless steel liner (the

liner must conform to the Class 3 requirements of CAN/ULC-S635) directly connected to the flue outlet

(Canada), see Figure 2.6b. A continuous 6" (152mm) stainless steel liner from the top of the chimney is the

optimum system and will provide the best performance, as well as compensate for poor draft situations

caused by large cross-sectional chimneys. The insert will not work without a positive seal in the chimney.

Chimneys constructed outside of the home, on an exterior wall, should be avoided if possible, especially in

colder climates. Outside chimneys may not draw as well and may downdraft due to the difficulty in heating

them up to operating temperature. Cooler chimneys will result in increased creosoting, less draft, and poorer

performance. Draft is proportional to overall chimney height as well as to stack temperature. Draft can be

increased by increasing chimney height, and by reducing heat loss from the chimney through an insulated

liner.

Ensure that all joints in the flue systems are tightly sealed, since any leaks will result in reduced

performance as well as a possible safety hazard.

This heating unit must serve as a supplementary heat source. An alternate heat source should be available in

the home if needed. The manufacturer cannot be responsible for additional heating costs associated with the

use of an alternative heat source.

It is highly recommended that the user buys this product from a retailer who can provide installation and

maintenance advices.
