This unit does not require a full reline (in USA only) when installing into a masonry fireplace, however, it
is recommended to ensure proper drafting of the appliance.
IMPORTANT: Ensure the chimney and firebox are cleaned and free of all debris, including soot and ashes,
before proceeding with this installation. If it is not clean soot maybe blown into the room through the
unit’s blower. Ensure the fireplace and chimney have not deteriorated in any way. If there is any sign of
corrosion or damage in the chimney the unit can not be installed. This unit can be installing in a masonry
fireplace built to (UBC 37 or ULC S628 standards) or a factory built fireplace (built to UL 127 or ULC S610
standards).
1. If installing the Empress with a skirt, the skirt must be installed before the installation.
2. Install the hearth pad. The floor 6” (150 mm) in front of the unit and 6” (150 mm) to each side of the
unit must be protected with a non-combustible hearth pad.
3. The vent connector from the insert must extend a minimum of 18” above the chimney seal plate. The
chimney seal plate area must be sealed to prevent the exhaust from the chimney from coming back

into the fireplace and prevent air
from the fireplace from entering
the chimney which will affect
proper drafting of appliance.
A qualified installer should evaluate
the existing fireplace to determine
the best method for achieving a
positive flue connection between
the vent pipe or liner and the
chimney. Whatever method used
must effectively seal the area to
prevent room air passage to the
chimney cavity of the fireplace.
A couple examples of Approved
Methods of Achieving a Positive
Flue Connection are:
a) Secure a seal-off plate (i.e.
22-gage sheet steel) in the
masonry fireplace throat using
masonry screws.
b) Pack non-combustible material
(i.e. rockwool) around the vent
pipe or using a flue adapter.
4. Set leveling leg to approximate
height.
5. Connect the Exhaust Starter Quick
Connect, straight or elbow, to the
exhaust pipe.
IMPORTANT:
The chimney seal plate must be removed for the annually chimney cleaning as ash will
build up on top of the plate.
