OFFSETS
Offsets can be handled with an offset adapter (it aligns
flue outlet of appliance with fireplace flue). For more
information on the offset adapter, see pages 9 and 25.
FIREPLACE CHIMNEY MAXIMUM SIZE TO ENSURE
PROPER DRAFT – USA ONLY
Note: Installations in Canada require a full-length liner.
The fireplace insert flue size is 6 inches (152 mm) di-
ameter, which is approximately 28 square inches (711
square mm), the minimum. The maximum flue size
should be no more than (3) three times the cross sec-
tional area of the size of the fireplace insert flue collar.
In this case, that would be no larger than a 10 inch (254
mm) diameter stack (area = approx. 85 sq. inches [216
sq. cm]).
Note: Formulas for calculating Area:
Calculating area of a circle:
π
x r
2
= Area (
π
= 3.1416, r = 1/2 diameter)
To calculate area of square or rectangle:
Width x Depth = Area
Notes:
It may be necessary to use a full-length liner to
achieve adequate draft for the appliance. A draft
gauge should .05” W.C., to .07” W.C. for opti-
mum performance
.
This appliance is approved for all heatform style
fireplaces (masonry fireplace with a metal fire-
box liner).
