Into a Factory Built Fireplace
Your Insert may be installed into a factory built fireplace (size permitting) with the following requirements:
1) Inspect your fireplace for damage or other physical defects. The fireplace must be in good working condition. If in doubt
about its condition, seek professional advice. Check for creosote build up or other obstructions inside the chimney,
especially if it has not been in use for some time. Before installing, clean your chimney system thoroughly.
2) A full stainless steel rigid or flexible flue liner meeting UL1777 (U.S.) or ULC S635 (Canada) must be used for both
safety and performance. The liner must be securely attached to the Insert flue collar and the chimney top.
3) The surround must be sealed to the fireplace front or the damper area around the chimney liner must be sealed to
prevent room air entering the chimney cavity of the fireplace.
4) The air flow within and around the fireplace must not be altered by the installation of the Insert (i.e. no blockage of
louvers or cooling air inlet or outlet ports). This includes the circulating air chambers in a steel fireplace or metal heat
circulator.
5) Alteration of the fireplace in any manner is not permitted with the following exceptions:
a: external trim pieces which do not affect the operation of the fireplace may be removed and stored on or within the
fireplace for re-assembly if the Insert is removed.
b: the chimney damper may be removed to install the liner.
