1.2 Venting Requirements
The flue is a critical component to a satisfactory installation. Your Drolet 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 2.3 , or a continuous stainless steel liner (the liner must conform to the Class 3 requirements of
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 creosoteing, 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.
