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. Using a fire screen at the extremity of the chimney
requires regular inspection in order to insure that it is not obstructed thus blocking the draught, and it
should be cleaned when necessary.
Do not connect this unit to a chimney flue serving another appliance.
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 recommended that the user buys this product from a retailer who can provide installation and
maintenance advices.
